SECTION 12: WCC III INST ALLA TION GUIDE __________________________________________
WCC III System Requirements
To accomplish remote communications via the internet, the following items are needed in addition to the WCC III system in order to control the building mechanical systems. The WCC III system is not to be used in any application where Fire/Life/Safety is an issue.
WCC III – MCD System Requirements (On-Site WCC III – MCD Computer):
DSL, or a Cable router/switch that connects to the
internet. Or, as an alternative, an internal jobsite IP network that does not connect to the internet, but when using this internal jobsite IP network, the external internet Email of alarms from the WCC III
- MCD will not be possible. Also, external access via the internet may not be possible.
A fi xed static IP address or a fi xed IP domain host
name.
Enabled port forwarding on the Firewall of the
router/switch. This is only if a fi rewall is used.
On earlier versions, antivirus software is initially
provided by WattMaster Controls, with Norton antivirus software for a period of 1 year. The customer must maintain the antivirus software after this 1-year period. Later versions are shipped with Linux as the operating system and do not require anti-virus software.
An Email address that supports a SMTP
server for SENDING with a pop server for RECEIVING Emails, and it must have “auth login” authentication. TLS or SSL modes are not supported. WattMaster Controls can provide an Email address with these requirements.
An Uninterruptible Power Supply (UPS) – 750-
Watt minimum
A wall mounting surface is preferred.
A dedicated 120VAC power circuit is required.
Front End Software Requirements (Operator Console Software):
A Microsoft Windows XP /Vista/Windows 7-based
computer.
Minimum hardware specifi cation for the Microsoft
Windows XP / Vista based computer is a Pentium IV running at 2.4 Giga Hertz with at least 1 GB of RAM, and 10 GB of spare hard drive space. A CDROM/DVD player is also required for software installation.

Basic Operating Conditions and Wall Mounting
The WCC III – MCD Basic Operating Conditions
The WCC III - MCD must be kept in a clean and dry area in the building. The ambient temperature must be between 50 and 100 °F, and the relative humidity must be kept between 0 and 90% (non­condensing). The interior components are cooled by ventilation fans within the WCC III – MCD unit, and therefore the unit should not be kept in tightly confi ned or enclosed areas. The WCC III - MCD is primarily designed to mount on a wall with the supplied brackets.
The WCC III – MCD computer requires 115 VAC power and must remain powered at all times for proper operation and control. The 115 VAC power circuit must be separate and dedicated exclusively to the WCC III – MCD computer.
The WCC III - MCD system is designed to automatically restart after a power failure. However, the industrial computer which acts as the WCC III Master Communications Device will not automatically reboot unless the power is shut off cleanly and then restored cleanly. During most power outages, the incoming 115 AC voltage could have great fl uctuations before the power nally fails. In a like manner, brownouts will usually cause the industrial computer to “lock-up.” That is to say, the screen will continue to display on the monitor, but the cursor will not respond to the keyboard commands. To prevent this “lock-up” issue from happening to the WCC III – MCD, an Uninterruptible Power Supply (UPS) is required on each and every WCC III – MCD computer.
An Uninterruptible Power Supply (UPS) provides emergency power to keep the WCC III Master Communications Device (personal computer) on-line for several minutes after a primary power failure. The UPS regulates the incoming power to the computer and shuts the power off cleanly several seconds after the power outage, or brownout. When the primary power is restored, the UPS brings the MCD back on-line automatically. The WCC III system does not lose any information since all of the programs and user entered data are stored on either a disk in the MCD, on rmware, or on battery backed memory in the satellite controllers.
Figure 12-1: Installing the six screws for the two wall mounting brackets of the WCC III – MCD Computer
Do not mount the WCC III – MCD computer straight into the drywall. The use of a ¾-inch plywood “Backer Plate Board” is required. You may want to paint this plywood “Backer Plate Board” to match the color of the wall before mounting to the wall.
See Figure 12-2 for further application.
Backer Plate Mounting Notes:
Use correct type of wall mounting anchors for mounting on a concrete wall for the mounting of the “Backer Plate Board” if and when mounting the Backer Plate Board to a concrete wall. Use at least 2-inch dry wall type screws if mounting the Backer Plate Board to a “Dry-Wall” type wall. Mount the “Backer Plate Board” so that the screws that are holding the “Backer Plate Board” are on the 16-inch centers of the wall studs where applicable.
Mount the WCC III - MCD 4-½ to 5-½ feet off of the ground on a suitable wall, in an air conditioned space. This area should not have any radio transmitting or telephone switching gear in the space, or near the space, or located on the back side of the adjacent wall.
Wall Mounting of the WCC III – MCD
It is strongly suggested that the WCC III – MCD is mounted on the wall. General guidelines are as follows:
Always install the supplied six screws for the two supplied wall mounting brackets for the WCC III – MCD Computer as shown in
Figure 12-1. Be sure to tighten the six screws so that they do not
loosen over time.
12-2
Do not block the airfl ow vents that are coming out of the WCC III- MCD. Do not apply paint to the WCC III-MCD enclosure. Do not cover the WCC III-MCD with any protective plastic while painting with the WCC III-MCD turned on. The UPS battery backup unit should be located within 3 or 4 feet of this WCC III – MCD.

WCC III - MCD Internet Access
WCC III – MCD Internet Access
The most common question asked is: Why does the WCC III – MCD computer need to have Internet access?
If WattMaster Controls factory assistance or troubleshooting is required for a WCC III system, a representative from the factory can access the system with a remote computer and view the same WCC III Screens as the end user or contractor in the building. This allows the end user or the contractor for the building installation to talk to the factory representative while they are both viewing the same screens.
The Emailing of important alarm notifi cations for up to 60 Email Addresses is provided for from the WCC III – MCD.
The ability to send alarm notifi cation via a text message to a cellular phone.
Secure Remote communications package (WCC III software) is provided for FREE. A CD-ROM is supplied for installation.
World-wide, multiple remote connections (up to 255 simultaneous connections possible)
On earlier versions, antivirus software is initially provided by WattMaster Controls, with Norton antivirus software for a period of 1 year. The customer must maintain the antivirus software after this 1-year period. Later versions are shipped with Linux as the operating system and do not require anti-virus software.
The ability for internet based tenant override requires internet access.
WCC III – MCD Cable Modem/Router T echnical Considerations
The WCC III-MCD uses internet access to e-mail alarms and to provide remote IP access for multiple remote WCC III operator programs.
The DSL / Cable modem USB connection should not be connected to any of the USB ports on the WCC III – MCD. The DSL / Cable modem Ethernet connection should only be connected to the Ethernet port on the WCC III – MCD if the DSL / Cable modem has a built-in internal router with Ethernet switch.
The use of a DSL / Cable modem with an external router that is then connected to the WCC III - MCD is also a recommended way to connect the internet to the WCC III – MCD. The use of only a plain DSL / Cable modem without an internal router with a built-in switch is not currently recommended by WattMaster Controls.
It is recommended that the WCC III-MCD computer be connected to the internet via a high-speed cable modem or NAT enabled router.
This is best accomplished by what is called Port Forwarding (also sometimes referred to as tunneling) and is the act of forwarding a network port (located External on the internet) to another network node (located Internal on the LAN). This technique can allow an external user (The WCC III program) to reach a port that is on a private LAN (Local Area Network) IP address (The WCC III ­MCD) from the outside via a NAT enabled router. This external port number that is used for the WCC III – MCD computer is port
39289.
Custom remote WCC III system programming or analyzing of the existing WCC III program is also available for a nominal charge.
Some cable modem devices may incorporate a router along with the cable modem functionality, to provide the LAN with its own IP network addressing. From a data forwarding and network topology perspective, this router functionality is typically kept distinct from the cable modem functionality (at least logically) even though the two may share a single enclosure and appear as one unit. So, the cable modem function will have its own IP address and MAC address as will the router.

WCC III - MCD Internet Access
In a typical WCC III - MCD networking setup, internet access is through a DSL or Cable modem. This modem may then be connected to a router with a built in switch, (or typically the router with switch is also built-in to the modem) which is then connected to the internal LAN of networked computers by Ethernet cabling. The NAT enabled router is the only device that the Internet sees as it holds the public IP address. On the other hand, the WCC III – MCD, located behind the NAT enabled router, is invisible to the Internet as it holds a local IP address on the NAT enabled router. Port forwarding is necessary in the NAT enabled router because computers that are running the WCC III program will send information that is directed to the public IP address and the NAT enabled router needs to know where to send and then redirect that information to the WCC III – MCD.
NOTE: A DSL modem is not recommended due to yet
another layer of setup complexity. DSL modem/routers also have a maximum distance from the local telephone company’s
main central offi ce. That distance is 18,000 feet.
Step 1: You will need a high-speed cable or DSL modem/router
that is NAT enabled and it must be setup by the ISP, or by IT (Information Technology) knowledgeable personnel, and it must also be connected to the Internet.
The default IP addresses that the WCC III – MCD is shipped with are:
WCC III-MCD IP Address: 192.168.100.100
WCC III-MCD Subnet Mask: 255.255.255.0
WCC III-MCD Default Gateway: 192.168.100.1
WCC III-MCD Preferred DNS Server: 208.67.222.222
WCC III-MCD Alternate DNS Server: 208.67.220.220
The external port number that is used for the WCC III – MCD computer is port 39289.
For WCC III – MCD’s running windows set up the WCC III – MCD BACKTASK.EXE Program
Com Port # ____________
External Port Range ____________
Default for the backtask.exe program is Comm port # 5 and port # 39289.
Step 2: The following three items are needed from your ISP
(Internet Service Provider) in order to set up the Cable / DSL modem/router for stand alone internet access. The ISP should have already supplied a sheet of paper that has this important information on it.

WCC III - MCD Internet Access
Supported Networks
Only Microsoft based networks are currently supported by the WCC III system. Any of the older 10 base T only networks are not supported by the WCC III system, only 100 base T or faster networks are supported. (10/100 base T are OK) The slower the network, the slower the data returned from the WCC III-MCD will be displayed, and the faster speed is always better.
Also, network “hub” devices are not recommended, because “hub” devices divide the network’s bandwidth amongst the active connections that are connected to the network hub. For example, if you have a 16-port network hub on a 100 base T connection with 10 active connections, then your effective network speed is the same as a 10 base T connection.
A 10/100 base T network switch is the recommended connection to the WCC III-MCD device. A network switch device has a full 100 base T connection to all active ports at the same time.
Benefi ts of Using a Separate DSL / Cable Modem Internet connection for the WCC III-MCD
1. It provides a layer of network isolation. A connection to the building’s internal computer network may not be desirable to the IT department. If the WCC III – MCD is connected to the building’s internal computer network an additional fi rewall into the building’s internal computer network may be required.
2. A dedicated high speed internet connection is a faster connection. WCC III displayed data will be displayed quicker and updated faster.
How to send a T e xt Message to a Cellular phone via an Email from the WCC III system
Most cellular telephone providers have as a free* option (Charges may apply in some instances) an Email-to-TEXT service for their cellular phone plans. *Usually the cellular telephone providers will have an unlimited text messaging option in one or more of their plans.
When using Verizon cellular service, the text messaging email address for your phone is your 10-digit phone number followed by @VTEXT.com. For example, if your phone number is 1-555­555-5555, your email address (for TEXT MESSAGING) would be 5555555555@VTEXT.com
When using Sprint cellular service, the text messaging email address for your phone is your 10-digit phone number followed by @messaging.sprintpcs.com. For example, if your phone number is 1-555-555-5555, your email address (for TEXT MESSAGING) would be 5555555555@messaging.sprintpcs.com.
When using AT&T cellular service, the text messaging email address for your phone is your 10-digit phone number followed by @txt.att.net. For example, if your phone number is 1-555-555­5555, your email address (for TEXT MESSAGING) would be 5555555555@txt.att.net.
Example: 5555555555@VTEXT.com, 5555555555@messaging. sprintpcs.com, or 5555555555@txt.att.net would be programmed into the WCC III System parameters screen as an Email address. Any alarm type level that is generated would be sent to that cellular telephone number as a text message.
3. Network outages should be less frequent, due to the fact that there is no overhead of a pre-existing internal computer network. A pre-existing internal computer network will always require periodic “downing of the network servers” to do maintenance work to the existing computer network regardless of having the WCC III-MCD connected to the pre-existing internal computer network.
4. The need for having an onsite IT person to setup, and then administer the WCC III-MCD will be reduced.
5. Setup and maintenance of e-mail accounts would be easier, because they would be automatically provided by the Internet Service Provider.

RS-485 Communication Wiring
The WCC III System RS-485 Communication Wiring
The WCC III - MCD can communicate with up to 239 satellite controllers via a two-wire RS-485 communication loop. On the back of the WCC III – MCD there are two RS-485 communication loop ports that come as standard. Each one of these communications loop ports can communicate with up to 60 satellites for a total of 120 satellites.
Two more additional RS-485 communication loop ports can be added at an additional cost for any WCC III system that has more than 120 satellites. The two-wire RS-485 communication loop should be stranded 2 wire twisted pair of 18-gauge wire with a shield wire, and it also must be plenum rated were applicable.
The use of stranded wire is mandatory to ensure a good connection with the ¼ inch Sta-Con connectors which are used to terminate the wires at the satellite controllers. The RS-485 communication wire does not have to be run from each satellite controller back to the WCC III – MCD, but rather the RS-485 communication wire can be “daisy-chained,” which means that only one twisted pair of wires is connected to each of the WCC III - MCD communications loops. The maximum allowable length of wire from the WCC III - MCD to the farthest satellite is 4000 feet per RS-485 communications loop.
The RS-485 wire specifi cations are generally a stranded 18- gauge - 2 wire twisted pair with shield. 18-gauge stranded wire is mandatory to ensure a good connection with the ¼ inch Sta-Con connectors, which are used to terminate the wires at the WCC III
- MCD and at the satellite controllers. The old SAT II Manchester communications loop was supposed to have used a 2-wire twisted pair with shield, but this was not used in every installation. This old SAT II communications loop should not be used for the new SAT III communications loop. A new RS-485 communications loop should be ran to each new replacement SAT III controller. The shield wire must be used on the new SAT III controller, as it provides a “ground” reference for the RS-485 communication loop. WattMaster Controls sells two versions of 18-gauge - 2-wire twisted pair with shield communications wire— (1) WattMaster part #WR-NL-WR-18 which is marked “Network Loop” with a red stripe for rapid identifi cation. This connection is intended to run from the WCC III – MCD to the SAT III, SAT 3C/D/F, SAT 3P, and then to the next SAT 3 type controllers. (2) WattMaster part # WR-LL-WG-18 which is marked “Local Loop” with a green stripe for rapid identifi cation for the TUC loops that run from the SAT 3C/D/F controllers out to the TUC controllers.
“Wire Nuts” on the RS-485 communications loop should be avoided at all costs. As an alternative to the “Wire Nuts”, WattMaster Controls has a Power and Switchable RS-485 communications board, and the WattMaster part number is PL102224. This Power and Switchable RS-485 communications board can be thought of as a 24-VAC power and communication distribution system for the SAT III communications loop, and this board will aid in initial startup and future troubleshooting of the SAT III communications loop. These boards should be used on a fl oor-by-fl oor basis. This Power and Switchable RS-485 communications board is also available in a small metal electrical enclosure.

WCC III Technical Guide
12. WCC III INSTALLATION GUIDE
WCC III - MCD Typical System Architecture
The wire that makes up the communication loop should be shielded. Shielded cable has an aluminum jacket over the wires that could act as an “antenna” to carry away any “stray” electrical signals that could interfere with the communication process. The shield should be grounded throughout the SAT Loop.
The SAT RS-485 communication loop wires are connected to the “R” and “T” and shield terminals on the satellite controllers using ¼-inch Sta-Con connectors. Make sure the polarity is correct. That is to say, the wire connected to the “R” and “T” terminal on the MCD must be connected to the “R” and “T” terminal on the satellite controllers. If the “R” and “T” and shield wires are crossed, the WCC III system will not communicate. The shield should be connected together when the cable is cut in order to terminate the wires at the satellite controller.
The communication loop wire from the WCC III - MCD is connected to one of the “R” and one of the “T” terminals on the satellite controller, which is physically located nearest the WCC III - MCD. The other “R” and “T” terminals located on the satellite controller can be used to extend the two-wire loop to the next satellite controller, or the wires can branch off of a two-wire loop
running through the center of a building as shown in Figure 12-6.
NOTE: The shield wire must be connected at each and every
Satellite Controller also.

Satellite Controller
Mounting in an Enclosure
The satellite controllers are designed to mount in any NEMA 1 or NEMA 3 standard, six-inch deep, electrical enclosure. Typically, this is a fi eld-mounted enclosure that contains transformers and any accessory items required such as a binary input board, V-Out Binary output board, control relays, etc. The best location for these satellite panels is mounted on a wall in equipment or storage areas or rooms at eye level near the controlled loads.
The satellite controllers may be ordered with or without the NEMA type enclosures. If you order the satellite controller from the factory without an enclosure, the SAT III and SAT 3C/D/F
dimensions as shown in Figure 12-13 and Figure 12-14 may be
helpful when selecting a suitable NEMA type enclosure.
The satellite controller must be mounted in an electrical enclosure. If you do not order the satellite controller with an electrical enclosure, you must provide your own electrical enclosure and then provide and then install your own fused disconnect switch, transformer, and terminal strip.
The size of the standard single SAT enclosure is designed to hold only one satellite controller (or up to two SAT 3C/D/F controllers), one fused disconnect switch, one transformer, one fi lter, and one terminal strip which is normally about 15” x 15” x 6” deep with an inter panel for mounting the SAT III controller, fuse block, 100VA transformer, etc. The size of the standard dual SAT enclosure is designed to hold two satellite controllers (or up to four SAT 3C/D/F controllers), one fused disconnect switch, two transformers, two lters, and two terminal strips is 30” x 18” x 6” deep with an inter panel for mounting the two SAT III controllers, fuse block, 100VA transformer, etc. If you install the satellite controller yourself, make sure you leave room for wires that need to be connected to the following terminals that are located on the sides of the SAT III satellite controller (minimum recommended clearance is 2 inches):
You can also have both a SAT III controller and up to two SAT 3C/D/F controllers in the same dual enclosure.

Satellite Controller Wiring
If you order the satellite controller in an enclosure, the factory will provide and install the wires from the transformer to the satellite. If you order the satellite controller separately, you must provide a NEMA panel with an inter panel, disconnect switch, transformer(s), fusing, terminal block(s), wire, crimp connectors, and then install the wires from the transformer to the satellite controller. A typical satellite controller wiring diagram is shown below:

SA T III LED Descriptions
SA T III Controller—LED Information (SS5003)
The SAT III Controller has 24 LEDs on the cover of the SAT III controller. The top 8 Status LED functions are as follows:
SAT REC - This LED will be lit when communications are being
received by the SAT III Communications Loop.
SAT XMIT - This LED will be lit when communications are being
transmitted by the SAT III Communications Loop.
HSS REC - This LED will be lit when communications are being
received from the HSS port.
HSS XMIT - This LED will be lit when communications are
being transmitted to the HSS port.
LOCAL SET - This LED will be lit when communications
with the WCC III-MCD has not occurred for at least the last two minutes. This means that the SAT III is not communicating on the SAT III communications loop. Setpoint control in the SAT III is dependent on the LOCAL SET parameters which are programmed into each control point by the user.
STATUS 1 - LED blinks every 1 second if SAT III is alive. STATUS 2 - LED blinks every 1 second during power on delay,
and then blinks every 8 seconds when watchdog is enabled.
STATUS 3 - LED blinks for every internal calculation loop
completion.
The lower 16 LEDs display the status of the 16 “H” and “C” Relay Outputs. The 16 LEDs display the status of the eight “H” and eight “C” contacts.

SA T III Connection Points
SA T III Controller — Connection Points
All of the external SAT III connection points are single tab ¼-inch Sta-Con connectors. With the exception of the “old” connection method of connecting the Binary Inputs which are 16-pin dip cable connections and the HSS EXP COMM port which is a 6-pin pre­made MOLEX type mini-fi t cable connection.
+V Connections.
There are eight +12-VDC connections that power analog type sensors of which the fi rst seven of these connections are fi xed to +12VDC only. The eighth +V connector is jumper (JP1) selectable for either +12VDC, or +24VDC. This (JP1) jumper can be set to +12VDC, or +24VDC so that the voltage at the eighth +V connection point is either +12VDC or +24VDC. The +24VDC is useful when connecting 4-to-20 mA sensors that require a connection voltage greater than +12VDC. You may connect up to eight 4-to-20 mA sensors to this eight +V (+24VDC) connection point. This JP1 jumper is located under the cover of the SAT III controller, just to the right of the eighth +V connector.
A TI Connections
These eight connections are connection points for ATI #1 to ATI #8 analog inputs. ATI is the acronym for Analog Temperature Input. These eight connection points are for Analog Inputs. This is where analog type sensors are connected to the SAT III controller. The types of sensors inputs that are supported on the SAT III controllers are: 0-1V, 0-5V, 0-10V, 10K Type 3 Thermistor, 4-20mA (On both the 0-1V, and 0-5V inputs). There are also eight Analog Input selection jumpers that are located under the cover of the SAT III controller near the Analog Inputs that actually set the type input voltage ranges for each of the eight analog inputs. These Analog Input selection jumpers are labeled JO1 to JO8. JO1 corresponds to analog input #1, JO2 corresponds to analog input #2, JO3 corresponds to analog input #3, JO4 corresponds to analog input #4, JO5 corresponds to analog input #5, JO6 corresponds to analog input #6, JO7 corresponds to analog input #7, JO8 corresponds to analog input #8. Each of these Analog Input selection jumpers has four jumper options: 0-1V, 0-5V, 0-10V, and THERM. See
Figure 12-34 and 12-35 for further wiring details. See Section 3
for further programming instructions.
GND Connections
These GND connections are analog ground common connection points for all of the analog input (ATI), and analog output (VOUT) connections.
VOUT 1 to V OUT 8 Connections
These eight analog outputs are set up to provide 0 to +15 DC Volts outputs at up to 15 milli-amps per output. These outputs are typically used to drive a VFD, 0-10VDC or 2-10VDC actuator or
valve. VOUT is the acronym for Voltage Output. See Section 3 for
additional programming instructions.
H 1 to H 8 Connections
The eight “H” connection points of the SAT III controller were originally classifi ed and labeled as “HEAT” contacts starting with the SAT 0, SAT I, and SAT II controllers. They do not need to be used only for “HEAT” contacts, as these contacts are general purpose relay outputs. There is a load protection device called a varistor across each of the eight “H” output connections that limit the allowable voltage to no more than 32 volts AC\DC maximum at 1 amp current draw for each contact. Attempting to switch any voltage greater than 32 Volts, or current draws of more than 1 amp per contact could and will result in damage to the SAT III controller. These “H” and “C” contact outputs are meant to control tri-state actuators, contactors, relays, solenoids, and the PI board AKA “ECC II ANALOG OUTPUT” board that WattMaster
Controls used to manufacture. See Figure 12-18 for further wiring details. See Section 3 for additional programming instructions.
COM 1 to COM 8 Connections
The COM1 connection point is a common connection point for H1 and C1 Relays. None of the COM connections are connected to any of the other seven COM connection points. A jumper cable is available to connect all of the COM connection points together. Each corresponding “H” and “C” contact are connected to a single corresponding “COM” connection point. So “H1” and “C1” are connected to “COM1”, “H2” and “C2” are connected to “COM2”,
etc. See Figure 12-18 for further wiring details.
WCC III Technical Guide
12-17
12. WCC III INSTALLATION
SA T III Connection Points
C 1 to C 8 Connections
The eight “C” connection points of the SAT III controller were originally classifi ed and labeled as “COOL” contacts starting with the SAT 0, SAT I, and SAT II controllers. They do not need to be used only for “COOL” contacts, as these contacts are general purpose relay outputs. There is a load protection device called a varistor across each of the eight “COOL” output connections that limits the allowable voltage to no more than 32 volts AC\DC maximum at 1 amp current draw for each contact. Attempting to switch any voltage greater than 32 Volts, or current draws of more than 1 amp per contact could and will result in damage to the SAT III controller. These “H” and “C” contact outputs are meant to control tri-state actuators, contactors, relays, solenoids, and the PI board AKA “ECC II ANALOG OUTPUT” board that WattMaster
Controls used to manufacture. See Figure 12-18 for further wiring details. See Section 3 for additional programming instructions.
Binary Inputs
The SAT III controller has two sets of eight-position dipswitches on its front panel labeled L1 - L8 and L9 - L16. Switches L1-L8 are housed together in one dipswitch, and switches L9-L16 are housed together in another dipswitch. For the old connection method one dipswitch is removed for each Binary Input with Time Delay board, and is then replaced with a ribbon cable which connects the Binary Input with Time Delay board to the SAT III controller. The binary devices to be monitored are then wired to the terminal strip of the Binary Input with Time Delay board. The Binary Input with Time Delay board requires a 24-VAC power source. Warning you must observe polarity on the 24-VAC and GND connections of both the Binary Input with Time Delay board and the SAT III controller, as the grounds must be the same. Or, an alternative connection method to the SAT III controller is now provided by the 6-pin HSS
expansion port on the side of the SAT III controller. See Figures 12-26, 12-27, & 12-28 for further wiring details.
24V AC & GND Connection
Located on the bottom side of the SAT III controller is a 24 VAC and GND connection. This is the main power connection to the SAT III controller. Each SAT III Controller draws - 15VA. External relays and contactors are not included, but need to be considered for total VA draw. The GND connection points must be the same between all of the externally powered expansion boards and the
SAT III Controller. See Figure 12-27 for further wiring details.
SA T Communica tion Connection
These connection points are for wiring of the RS-485 communication loop. There are two “T” (Transmit) connections, two “R” (Receive) connections and two “SHIELD” connection points. There are two connection points provided for each connection for easy “daisy chaining” to the next Satellite Controller. When connecting the RS-485 wiring from SAT III to SAT III or SAT 3C/D/F, or SAT 3P controller the wiring connections are as follows: connect “R” TO “R”, “T” TO “T”, AND “SHIELD” TO “SHIELD” OR “SH”. The RS-485 wire specifi cations are plenum-rated, jacketed stranded 18-gauge, 2-wire twisted pair with shield. 18-gauge stranded wire is mandatory to ensure a good connection with the ¼-inch Sta-Con connectors which are used to terminate the wires at the WCC III ­MCD and at the satellite controllers.
HSS EXP COMM Connection
The HSS EXP (Expansion) Port enables newer versions of the satellite expansion boards, most notably the Binary Input with Time Delay Board and V-Out RELAY Board to work without connecting the previous way (separate power and hard wiring was required). The SAT III has a single connection via the built-in HSS EXP port on the side of the SAT III. It is designed to connect and power up 5 HSS Expansion Boards. Connecting more than 5 HSS Boards is possible, but each additional board will require a 24VAC power supply.
The HSS EXP port provides power and ground, along with communications on a 6-pin pre-made MOLEX type mini-fi t cable connection. This cable is made with 16-gauge wire.
Each HSS Expansion Board has an 8-position address dipswitch that is used to set up the function of the board.
The HSS EXP port can be daisy chained to the next board. The HSS cable connections allow the HSS expansion boards to be located up to 150 feet away from the SAT III Controller.
HSS connection cables are available in the following sizes: 6-inch, 12-inch, 18-inch, 3 feet, 25 feet, 40 feet, 80 feet, and 120 feet.

SA T III Addressing
Addressing (Numbering) of SA T III Controllers
The WCC III system can have up to 239 SAT III controllers. In order for the central computer to communicate properly with each individual SAT III controller, each controller must be assigned a separate number, or address. The number is assigned by placing the small dip switches on the front of the SAT III controller marked “SAT ADDRESS” in the proper position.
The address dip switches are additive; that is to say placing switches 1 and 2 in the ON position will cause the SAT III controller to be identifi ed as satellite controller number 3. The SAT III controller looks at the position of these switches only when it is going through its initialization process after being powered up. Simply changing the switch positions on a SAT III controller that is currently “on-line” will not change its number. The switches need to be placed in the proper position before powering up the SAT III controller, or the SAT III must be powered down and then back up for the SAT III to “read” the new position of the switches. When placing the switches in the desired position, make sure the switch has “clicked” into place and is properly seated.
Figure 12-16: SAT III address switch loca tion
WCC III Technical Guide
12-19
12. WCC III INSTALLATION
SA T III Addressing
Care must be taken to ensure that two SAT III controllers do not have the same address. When this condition is present, the central computer does not know where to send the information, and the information that should be sent to the SAT III controller is usually lost.
You should be aware of the symptoms caused by two satellite controllers having the same number. Let’s consider a new job in which the satellite controllers have not yet been programmed and 2 SAT III controllers are named number #3. When you call up satellite controller #3 to enter data, everything will appear to be ne. You will be able to enter data on the screens as if nothing is wrong. However, when you leave a screen and then return to the same screen, all of the data you entered will be missing. Also, if you fi nish programming the analog inputs for example, and then go to the analog input summary screen to review your inputs, all of the data you have entered will be missing.
Another situation that you might encounter is adding a SAT III controller to an existing system and accidentally giving it the same number as a SAT III presently “on-line.” Again, when you begin to program the new SAT III controller, everything will appear fi ne until you leave a screen or if you go to a summary screen. Only now, all of the data is usually not missing. Generally, you get parts of your data back and parts will be missing.
If you suspect you might have two SAT III controllers with the same address (number 3 for example) the best thing to do is go to the SAT III controller that you know is number 3, and remove the 2-wire RS-485 communication loop from it. Then, go back to the computer and call up satellite controller #3. If the computer can still “talk” to satellite controller #3, there is another satellite controller that is addressed #3 connected somewhere on the RS­485 communication loop.
If a satellite controller was accidentally addressed #3, there will be a satellite number missing. For example, if satellite controller #7 was accidentally misaddressed to #3, satellite controller #7 will not be present. One way of telling which satellite controllers are
“on-line” is to go to the Satellite Summary Screen (see Section
3) and see which satellite controllers the computer recognizes as
being “on-line.”
If satellite controller #7 was accidentally miss-addressed #3, there would not be a satellite controller at address #7, and the computer will give a “Non-Existing” message for satellite controller #7.
Option 1, 2, and 3 Switches
Option switches 2 and 3 do nothing. But, the SAT III controller option “1” switch selects the A-to-D converter type that is on the mother board. With the switch turned OFF, the A-to-D curve is selected for the Maxim MAX147 part, and with the switch turned “ON” for the TI-ADS7844 (BB marked) the software will use the
special A-to-D curve for the TI-ADS7844 part. See Section 3 for
proper A-to-D identifi cation.
BA TT ON/OFF s witc h
This switch is used to turn the Battery (Rechargeable Super cap) ON and OFF to the SRAM located inside of the SAT III processor.
Since version 2.00 of the Satellite software the non-volatile memory is now also stored in the EEPROM, instead of the SRAM, and upon power up the memory is read from the EEPROM back into the SRAM. This switch is not of any importance anymore.
Local Set Switch
When the LOCAL dipswitch is in the ON position, the SAT III controller will operate according to their predefi ned user programmed “local set” setpoints. That is, if the SAT III controller was programmed by the user to correctly operate when and if the WCC III - MCD is off-line or disconnected.
Local Set Disable Switch
When the LOCAL SET Disable dipswitch is in the ON position, the SAT III controller will operate according to their predefi ned user programmed “On” setpoints. That is, if the SAT III controller were programmed by the user to correctly operate when and if the WCC III - MCD is off-line or disconnected.
Test Switc h
The test mode is active only if the TEST dipswitch is in the ON position. The word “TEST” can be input as the binary value within the SAT III. Example of use would be if the user programmed the word “TEST” into one of the control point values in the SAT III controller to check the operation of the SAT III controller with an alternate setpoint or schedule, the user could then place the TEST switch in the ON position to make this function work with out physically having to go back to the front-end computer to change a setpoint via the computer.

SA T III Relay Outputs
SA T III Relay Outputs
The standard SAT III controller is capable of providing 16 binary (on/off) relay outputs. These 16 relay outputs are for driving pilot duty relays. There is a load protection device called a varistor across each of the 16 output connections that limits the allowable voltage to no more than 32 volts AC\DC maximum at 1.0 or 1 amp current draw for each contact.
Attempting to switch any voltage greater than 32 Volts, or current draws of more than 1.0 or 1 amp per contact could and will result in damage to the SAT III controller. These “H” and “C” contact outputs are meant to control tri-state actuators, contactors, relays, solenoids, and the PI board AKA “ECC II ANALOG OUTPUT” board that WattMaster Controls used to manufacture. These relay outputs can be programmed in three different types of modes of basic operation: Time Clock, Dual Limit, and EA Mode. See
Section 3 for further details on Satellite programming instructions.

SA T III Relay Outputs
The terminals for the binary outputs are found at the lower left­hand corner of the SAT III controller and are labeled “H”, “COM”, and “C”. The relay contact can make or break a 24-VAC or 24­VDC circuit between the COM to H or COM to C terminals. The COM to H contacts are referred to as XXXK1h-K8h in the WCC III point addressing scheme, and the COM to C contacts are referred to as XXXK1c-K8c in the WCC III point addressing scheme. XXX is the Satellite address number 1 to 239, “K” stands for contact, and the numbers 1-8 stand for the channel on the SAT III controller.
Each “H” and “C” contact connection has a “COM” connection associated with it. Please note that each one of the sets of the corresponding “H” and “C” contacts are also isolated from each other. The “COM” connection means common. When wiring the control outputs, typically all of the “COM” connections are wired together, using the supplied jumper wire (PL100867). This “COM” common connection can either be connected to 24VAC / 24VDC or GROUND depending on the application.
Figure 12-18: SAT III “H” and “C” control output schematic
Figure 12-19: A control output common jumper wire is provided (PL100867) for connecting the eight “COM” connections together
The pre-made control output common jumper wire is provided in the initial spare parts kit that came with the SAT III controller. This spare parts kit contains various input load resistor packs, spare fuse, and the control output common jumper. The spare parts kit is WattMaster part number PL102029.

The “COM” or common connection point can either be connected to 24 VAC / 24 VDC or GROUND. It is basically a point of view of turning power “on” to a device, or removing “ground” going to the device. It makes no difference, as both methods will work equally well, and really depends on the application you are trying to control.

Proportional-Integral (PI) Output Board
Proportional-Integral (PI) Output Board
The Proportional-Integral (PI) Board is a separate integrated circuit board which works in conjunction with the SAT III controller to convert a pair of SAT III binary outputs to a varying DC voltage signal. When one contact on the SAT III controller closes, the voltage supplied by the PI board will ramp down at a pre-set rate. When the other SAT III contact closes, the voltage ramps up at the preset rate. When both contacts are open, the voltage supplied by the PI board will remain at its present value. The maximum DC voltage range is 0-14.5 volts, and the minimum allowable
resistance of the controlled device is 1000 ohms. See Section 3 for
further details on Satellite programming instructions.
Figure 12-21: ECC II Analog Output Board
12-24
WCC III Technical Guide
12. WCC III INSTALLATION GUIDE
PI Board Connection Points
The DC voltage range along with the ramp speed is set at the PI board. The ramp speed can be adjusted from 23 seconds to 38 minutes, and the maximum range is 0-14.5 volts DC.
To control a VFD drive from a SAT III controller using the Proportional-Integral board, you must use two control outputs and a circuit board (PI Board) that we no longer make. WattMaster Controls does not make the PI Output Board anymore, but Kele makes a similar circuit board that should work. It is a Tri-State-to­Analog Output circuit board (Kele Part # PWA-2T).
If only one contact closure is available to drive the PI Board, move jumper J01 on the WattMaster PI board to the B-C position and use the SAT III’s control output in the Dual Limit mode to control the PI Board. Although when using this method with the WattMaster PI Board, the DC voltages supplied by the WattMaster PI Board will either be increasing or decreasing at the set ramp speed depending on if the contact is open or closed.
The Global Analog Mode 9 Dual Ramp Screen was created to help emulate the old WattMaster PI board in software. It basically uses the control set points of two control outputs on a satellite controller to control a single analog output on a satellite controller and should be used when controlling an analog actuator or VFD that needs to
have an analog control setpoint. See Section 3 for further details on
Satellite programming instructions.
The Proportional-Integral (PI) Board ­connection points
All of external connections to Proportional-Integral (PI) Board connection points are non de-pluggable screw-cage type of wire clamped based terminal blocks.
24 V AC (TB1-5) & GND (TB1-6)
ANALOG OUT (TB2-1) & GND (TB2-3&4)
The “ANALOG OUT” and “GND” terminals supply the DC voltage from the PI board.
Adjust Minimum Voltage
The PI board is factory set for a minimum voltage of 0 VDC +/-
0.2 VDC. If you want a minimum voltage other than 0 VDC, you can reset it by adjusting the potentiometer (pot) labeled “R9.” The voltage between test point #3 (labeled “TP #3” on the PI board) and ground is set 300 mV lower than the desired minimum voltage. That is to say, if you want 5 VDC as the minimum voltage to be supplied between the “ANALOG OUT” and “GND” terminals, adjust pot “R9” to get 4.7 VDC between “TP #3” and “GND.”
NOTE: The minimum voltage setpoint must be lower than the
maximum voltage setpoint.
Adjust Maximum Voltage
The PI board is factory set for a maximum voltage of 14.5 VDC +/- 0.2 VDC. If you want a maximum voltage other than 14.5 VDC, you can reset it by adjusting the potentiometer (pot) labeled “R10.” The voltage between test point #2 (labeled “TP #2” on the PI board) and ground is set at 300 mV above the desired maximum voltage. That is to say, if you want a maximum voltage of 10 VDC to be supplied by the “ANALOG OUT” and “GND” terminals, adjust pot “R10” to get 10.3 VDC between “TP #2” and “GND.”
NOTE: The maximum voltage setpoint must be higher than
the minimum voltage setpoint.
The PI board requires a 24 VAC power supply which is connected to these terminals. The PI board is generally powered by the same 24 VAC transformer that powers the satellite controller. The GND connection points must be the same between the PI board and the SAT III Controller.
HEA T (TB1-1) & COM1 (TB1-2)
When 24 volts AC is supplied between the “HEAT” and “COM1” terminals, the DC voltage supplied by the PI board will start increasing at the set ramp speed.
COOL (TB1-1) & COM2 (TB1-4)
When 24 volts AC is supplied between the “COOL” and “COM2” terminals, the voltage supplied by the PI board will start decreasing at the set ramp speed.
WCC III Technical Guide
Adjust “Ramp” Speed
The ramp speed is the time it takes for the DC voltage between the “ANALOG OUT” and “GND” terminals to change from the minimum voltage to the maximum voltage and vice versa. The ramp speed is factory set at about 19 minutes. If you want a ramp speed other than 19 minutes, you can reset it by adjusting the potentiometer (pot) located at R2. When R2 is fully counterclockwise, the ramp speed is 38 minutes (+/- 10%). When R2 is fully clockwise, the ramp speed is 23 seconds (+/- 10%). As the voltage is ramping up, the small light labeled D1 will fl ash and as the voltage is ramping down, the small light labeled D2 will fl ash.

If you want to test the ramp speed, disconnect all wires from the “HEAT,” “COM1,” “COOL,” and “COM2” terminals and use a volt meter to measure the DC voltage between “ANALOG OUT” and “GND” as you jumper test point #4 (TP #4) to ground.
The voltage should increase from the minimum to the maximum voltage during the set time interval. Then, remove the jumper from “TP #4” and jumper “TP #5” to “GND.” The voltage between the “ANALOG OUT” and “GND” terminals should decrease from the maximum to the minimum voltage during the set time interval.

Old SA T II Type Binary Input with Time Delay Board
Sequence of Operation
When the SAT III controller makes COM to H, 24 VAC is supplied to the “HEAT” terminal on the PI board which causes the DC output voltage supplied by the PI board to increase the output voltage at the preset rate.
When the SAT III controller makes COM to C, 24 VAC is supplied to the “COOL” terminal on the PI board which causes the DC output voltage supplied by the PI board to decrease the output voltage at the preset rate. When both the COM to H and COM to C terminals are open on the SAT III controller, the DC output voltage supplied by the PI board will remain at its present value.
Previous “Old” SA T II Type Binary Input with Time Delay Board
The SAT II type Binary Input with Time Delay board is an optional integrated circuit board which can interface with the “old” SAT II as well as the “new” SAT III controllers to allow it to monitor the status of remote mounted binary (on/off) devices such as switch closures, air fl ow switches, etc. One binary input board enables the SAT II or SAT III controller to monitor up to 8 binary inputs, and 2 binary input boards can be used with 1 SAT II or SAT III controller for a total of 16 binary inputs per SAT II or SAT III controller.
The SAT III controller comes standard with two eight-position dipswitch switches on its front panel labeled L1 - L8 and L9 - L16 which are in effect manually controlled binary inputs. The SAT III controller monitors the on/off status of these switches and can control and/or alarm based on the position of these dipswitches. The Binary Input with Time Delay board allows the eight-position dipswitches to be replaced with a terminal connection points which will accept wiring for remote-mounted binary input devices.
The SAT III controller has two sets of eight-position dipswitches on its front panel labeled L1 - L8 and L9 - L16. Switches L1-L8 are housed together in one dipswitch, and switches L9-L16 are housed together in another dipswitch. One of the dipswitches is removed for each Binary Input with Time Delay board, and is then replaced with a ribbon cable that connects the Binary Input with Time Delay board to the SAT III controller. The binary devices to be monitored are then wired to the terminal strip of the Binary Input with Time Delay board. The Binary Input with Time Delay board requires a 24 VAC power source. Warning: You must observe polarity on the 24 VAC and GND connections of both the Binary Input with Time Delay board and the SAT III controller, as the grounds must be the
same. See Section 3 for further details on Satellite programming
instructions.

With the exception of the “old” connection method of connecting the Binary Input with Time Delay board to the SAT III controller which is a 16- pin dip cable connection.
24 V AC & GND (TB2)
The SAT II type Binary Input board requires a 24 VAC power supply that is connected to these terminals. The SAT II type Binary Input board is generally powered by the same 24 VAC transformer that powers the satellite controller. The GND connection points must be the same between the SAT II type Binary Input board and the SAT III Controller.
Contact Inputs 1 to 8 and GND
When the contact is closed between one of eight inputs of the contact inputs connector and ground it will activate one of the eight LEDs and makes a simulated contact closure on the P1 connector. This P1 connector is then connected via a 16-pin ribbon cable to one of the SAT III controller’s former Binary Input dipswitch locations. This input is automatically kept on for a timed duration depending on the value of the dipswitch that is located on the “old” SAT II type Binary Input with Time Delay board.
P1 (Socket Connection to One of the
SA T III Binary Input Former Dipswitch Locations)
This connector is polarized, and must be properly inserted at both ends. Pin #1 of the P1 socket must mate with Pin # 1 of one of the SAT III former dipswitch locations. (The dipswitch on the SAT III must be removed).

The “Old” SAT II T ype Binary Input with Time Delay Board Installation and Mounting
It is important to mount the “old” SAT II type Binary Input with Time Delay board in a location that is free from extreme high or low temperatures, moisture, dust, and dirt. Be careful not to damage any of the electronic components when mounting the “old” SAT II type Binary Input with Time Delay board. Remove the “old” SAT II type Binary Input with Time Delay board from its Snap-Track mount. Using the Snap-Track as a template, mark the two mounting holes. Drill pilot holes in the enclosure back panel, and secure the Snap-Track using sheet metal screws. Do not allow metal shavings to fall onto the “old” SAT II type Binary Input with Time Delay board. Reattach the “old” SAT II type Binary Input with Time Delay board into the Snap-Track.
Latest WCC III Binary Input with Time Delay Expansion Board (HSS EXP PORT) - (SS5006)
The new WCC III Binary Input with Time Delay board provides a terminal point for landing wire for an external input switch / relay contact. It can interface to the SAT III controller via a 16-pin ribbon cable with “DIP” connectors on both sides. Connect “J1” on the Binary Input board to one of the two removable dipswitches on the cover of the SAT III controller. These two switches are labeled Binary Inputs on the cover of the SAT III controller. Or, an alternative method of connection to the SAT III controller is provided by the 6-pin HSS communications port on the side of the SAT III controller. The eight Binary Inputs on the new WCC III Binary Input with Time Delay board are dry contact closures to ground only. There is a Time Delay switch on the new WCC III Binary Input with Time Delay board. This Time Delay switch determines how long the input will stay on after a momentary switch contact is applied to the input of the new WCC III Binary Input with Time Delay Board.
With the Time Delay dipswitch (1 to 6) all OFF, there is no delay ON for all eight inputs. Time Delay dipswitch (1 - 15 MIN) ON there is a 15-minute delay ON for all eight inputs. Time Delay dipswitch (2 - 30 MIN) ON there is a ½ hour delay ON for all eight inputs. Time Delay dipswitch (3 - 1 HOUR) ON there is a 1 hour delay ON for all eight inputs. Time Delay dipswitch (4 - 2 HOUR) ON there is a 2-hour delay ON for all eight inputs. Time Delay dipswitch (5 - 3 HOUR) ON there is a 3-hour delay ON for all eight inputs. Time Delay dipswitch (6 - 4 HOUR) ON there is a 4-hour delay ON for all eight inputs. These Dipswitch settings are additive. With Time Delay dipswitch (1 - 15 MIN, 2 - 30 MIN, and 3 - 1 HOUR) ON, there is a 1 hour and 45 minute delay ON for all eight inputs.
NOTE: This Time Delay dipswitch is ignored when the
Binary Input with Time Delay board is connected via the HSS port. There are 16 independent Time Delays on the Binary Input screen of the WCC III front-end software. One for each of the 16 binary inputs.
The eight input status LEDs on the new WCC III Binary Input with Time Delay board also do not work during a time delay when it is connected to the SAT III via the HSS port.
The Binary Input board power requirements are 24VAC and it draws 5 VA. The 24 VAC power connection is P2, and you must observe polarity when connecting this power connection to the SAT III.
HSS connection cables are available in the following sizes: 6-inch, 12-inch, 18-inch, 3 feet, 25 feet, 40 feet, 80 feet, and 120 feet.

All external WCC III Binary Input with Time Delay board connection points are de-pluggable screw-cage type of wire clamped based terminal blocks. With the exception of the “old” connection method of connecting the Binary Inputs which are a 16-pin dip cable connection, and the HSS EXP COMM port which is a 6-pin pre-made MOLEX type mini-fi t cable connection.
HSS Connectors (P2 & P3 Communications)
There are two of these 6-pin Mini-fi t connectors, and each of these connectors could provide power and communications to and from the WCC III Binary Input with Time Delay board to the SAT III controller. These connectors are generally called HSS ports. The WCC III Binary Input with Time Delay board requires 24 VAC and ground connections which are then connected into these connector terminals. The WCC III Binary Input with Time Delay board is generally powered by the same 24 VAC transformer that powers the satellite controller. Communications to the SAT III controller is also in this cable, along with a shield wire. The 6-pin HSS cable connections can also be daisy chained to other WCC III Binary Inputs with Time Delay boards and WCC III V-Out relay boards.
Contact Inputs 1 to 8 and GND
When the contact is closed between one of eight inputs of the contact inputs connector and ground it will activate one of the eight LEDs and makes a simulated contact closure on the J1 connector. This J1 connector is then connected via a 16-pin ribbon cable to one of the SAT III controller’s former Binary Input dipswitch locations. This input is automatically kept on for a timed duration depending on the value of the dipswitch that is located on the WCC III Binary Input with Time Delay board. As an alternative connection method the HSS connection between the SAT III controller and the WCC III Binary Input with Time Delay board delay board has the ability to instantaneously notify the SAT III controller that an Input has changed. And, from within the SAT III Binary Input screen, the individual time duration for each and every binary input could be set differently.
J1 (Socket connection to one of the SA T III
Binary Input former dipswitch loca tions)
This connector is polarized, and must be properly inserted at both ends. Pin #1 of the J1 socket must mate with Pin #1 of one of the SAT III former dipswitch locations. (The dipswitch on the SAT III must be removed) If using the HSS connection method, this connection to the SAT III controller does not need to be connected.

SA T III V-Out Board
SA T III V-Out
The SAT III controller has the capability of providing 8 analog output signals which have a maximum range of 0-15 VDC. These eight voltage outputs can be used to control actuators, and WattMaster Controls V-Out boards.
Previous “Old” SA T II T ype V-Out Binary Interface Board
A standard SAT III controller is capable of providing 8 analog outputs and 16 binary outputs. The “older” V-Out Binary Interface Board (V-Out board) allows the user to obtain additional binary outputs from the SAT III controller by converting the analog outputs to binary outputs.
Chip switches located on the “older” V-Out board open and close based on the 0-15 VDC signal from the analog outputs. The chip switches on the “older” V-Out boards are not identical to those used for the binary outputs on the SAT III controller.
The changeover setpoint along with the hysteresis is adjustable at the V-Out board. The changeover setpoint is the DC voltage required to open the chip switches on the “older” V-Out board. The hysteresis is the amount the voltage signal must change before the relay changes state. The changeover setpoint is set at 7.5 VDC at the factory, and the hysteresis is set at 2 VDC.
The “older” V-Out board has one changeover setpoint and one hysteresis setpoint which affects all eight binary outputs unless optional potentiometers are ordered separately. One potentiometer is required for each separate changeover setpoint, and one potentiometer is required for each separate hysteresis setpoint. Therefore, a binary output board with a separate changeover and hysteresis setpoint for each binary output would require 16 potentiometers.
If you have a standard “older” V-Out board, R19 is the potentiometer which controls the changeover setpoint and is marked “SET 1.” The potentiometer at R9 controls the value of hysteresis and is labeled “DELTA B.” To adjust the changeover setpoint, use a meter to measure the DC voltage between pin 3 of U4 and ground as you adjust potentiometer R19. To adjust the hysteresis, measure the DC voltage between pin 5 of U4 and ground as you adjust the potentiometer at R9.
To understand how the “older” V-Out board works better, consider a changeover setpoint of 7.5 VDC with a hysteresis of 1 VDC. The chipswitch on the “older” V-Out board will open when the voltage is 8.5 VDC and will not close until the voltage drops to 6.5 VDC. Assume the Analog Input Screen on the WCC III system is set up according to the following parameters:
When the space temperature rises to 73 °F, the voltage supplied to the V-Out board from the SAT III controller will be 8.5 VDC which will cause the relay to open. As the space temperature drops to 72°F, the voltage supplied to the V-Out board will be 6.5 VDC which will cause the relay to close.
For the older SAT II controller: The V-Out board can convert from 1 to 8 of the analog outputs to binary outputs. One digital to analog converter (DAC or V-Out module) is required for each set of 4 analog outputs to be converted to binary outputs. Therefore, if 1 to 4 analog outputs are to be converted to binary outputs, 1 V-Out module is required, and if 5 to 8 analog outputs are to be converted to binary outputs, 2 V-Out modules are required. These V-Out Modules are now built into the SAT III controller and do not need to be ordered separately.

The “Old” SAT II T ype V -Out Board ­Connection Points
All external “old” SAT II type V-Out board connection points are single tab ¼-inch Sta-Con connectors.
VIN1 to VIN8 Connection
These analog inputs are set up as 0 to +15 DC Volts inputs. They should be connected to and mated up with the SAT III controller’s 8 Analog Outputs. These eight inputs need to be connected to the SAT III V-Out connections for the V-Out mode of operation to function.
GND Connection
This is an analog ground common connection point for VIN1 to VIN8 analog inputs. It is important that this “analog” ground is connected to the Analog Input ground of the SAT III controller.
24 V AC & GND
The “old” SAT II type V-Out board requires a 24 VAC power supply, which is connected to these terminals. The “old” SAT II type V-Out board is generally powered by the same 24 VAC transformer that powers the satellite controller. The GND connection points must be the same between the “old” SAT II type V-Out board and the SAT III Controller.
RL Y 1 to RLY 8 COM – N.O . Connections
These are the eight “Chip-switch” relay driver contacts on the “old” SAT II type V-Out board. These are to be used for powering of pilot duty relays. No more than 24 VAC to be switched by these “Chip­switches”. There is no load protection device called a varistor on any of these 8 “Chip-switch” relay driver output connections of the “old” SAT II type V-Out board. These chip-switches can only switch AC type voltage, not DC type voltage, with a maximum at ½ amp current draw for each chip-switch relay driver output contact. Attempting to switch any current draws of more than 1/2 amps per contact could and will result in damage to the “old” SAT II type V-Out board and/or to the SAT III controller.
A pre-made control output common jumper wire (PL100867) can be used to connect all eight of the relay common connections of the “old” SAT II type V-Out board together.
The “Old” SAT II T ype V -Out Board Installation and Mounting
It is important to mount the “old” SAT II type V-Out board in a location that is free from extreme high or low temperatures, moisture, dust, and dirt. Be careful not to damage any of the electronic components when mounting the “old” SAT II type V-Out board. Remove the “old” SAT II type V-Out board from its Snap-Track mount. Using the Snap-Track as a template, mark the two mounting holes. Drill pilot holes in the enclosure back panel, and secure the Snap-Track using sheet metal screws. Do not allow metal shavings to fall onto the “old” SAT II type V-Out circuit board. Reattach the “old” SAT II type V-Out board into the Snap-Track.
WCC III V -Out RELA Y Board Sequence (SS5008)
There are two modes of operation for the WCC III V-Out RELAY board. One is the V-Out mode, and the other is the Binary Output mode.
The WCC III V-Out RELAY board has eight relays each with N.O. (Normally Open) contacts. These relay contacts are rated for 1 Amp at 24 VAC/VDC operation only. This WCC III V-Out RELAY board connects to the HSS expansion port on the side of the SAT III controller. The WCC III V-Out RELAY board is an expansion board that allows for another 8 binary outputs (Relay Contacts) to be used with the SAT III controller. Up to three of these WCC III V-Out RELAY boards may be connected to the SAT III HSS expansion port. Two boards in the Binary Output mode are supported, and one board in the V-Out mode is supported. One HSS expansion board will add 10 VA of VA load to the SAT III power requirement.
These eight Analog Inputs connections must be connected to the eight Analog Outputs of the SAT III controller in the V-Out mode of operation. These analog values are not digitally transmitted via the HSS port on the SAT III to the WCC III V-Out RELAY board in the V-Out mode.
There is a load protection device called a varistor across each of the 8 relay output connections of the WCC III V-Out RELAY board that limit the allowable voltage to no more than 32 volts AC\DC maximum at 1 amp current draw for each relay output contact. Attempting to switch any voltage greater than 32 volts or current draws of more than 1 amp per contact could and will result in damage to the WCC III V-Out RELAY board and/ or to the SAT III controller.

WCC III V -Out Relay Board
The connecting HSS cable is available in 1-ft, 1½-ft, 3-ft, 25-ft, 40-ft, 80-ft, and 120-ft lengths. No more than 150 feet of total wire can be used to power a SAT III HSS loop.
The dipswitch on the WCC III V-Out RELAY board sets the various modes of operation, and dead band in the V-Out mode.
Dipswitch SW1-7 (MODE 2 - V-Out Mode) and SW1-8 (MODE 1 - Binary Output Mode) selects the MODE of operation for the WCC III V-Out RELAY board.
If both MODE (SW1-7 and SW1-8) switches are OFF then the WCC III V-Out RELAY board is in Binary Output mode. Binary Output 1 to 8 is selected. If MODE 1 switch (SW1-8) is “ON” then Binary Output 9 to 16 is then selected. If MODE 2 Switch (SW1-7) is “ON” then the V-Out mode is selected. You must cycle power to the WCC III V-Out RELAY circuit board after setting dip switch SW1-8. You may select any other switch setting without cycling power to the board.
SW1-1 (1) (V-OUT MODE - ADDS 1 VOLT TO DEAD BAND)
SW1-2 (2) (V-OUT MODE - ADDS 2 VOLTS TO DEAD BAND) (V-OUT MODE DEFAULT SETTING ON)
SW1-3 (4) (V-OUT MODE - ADDS 4 VOLTS TO DEAD BAND)
SW1-4 (8)
SW1-5 (16)
SW1-6 INVERT (V-OUT MODE) (FLIPS CONDITION OF THE RELAY OUTPUTS)
SW1-7 MODE 2 (V-OUT MODE) (V-OUT MODE DEFAULT SETTING ON)
SW1-8 MODE 1 (When changing this switch, you must cycle power to the circuit board)
Binary Output Mode of Operation
When the WCC V-Out RELAY board is set for the Binary Output mode (SW1- switch # 8 is either “ON” or “OFF” and SW1 - switch #7 is “OFF”) the eight relays of the WCC V-Out RELAY board are controlled by the WCC III program setup of the SAT Binary Output screens for each satellite controller. SW1- switch # 8 “OFF” is Binary Output board address relays 1 to 8, and SW1- switch # 8 “ON” is Binary Output board address relays 9 to 16. This assumes that SW1 - switch #7 is “OFF”.
V-Out Mode of Operation (Hysteresis is Added to the Setpoint via Setting of the SW1 Dipswitch)
When the WCC V-Out RELAY board is set for the V-Out mode (SW1- switch # 7 “ON”), the relay output will turn “ON” when the input voltage rises above 7.5 VDC (+/- .25V) plus the dead band setting that is determined by SW1 settings. When the WCC III V-Out RELAY board is set for the V-Out mode, the relay output will turn “OFF” when the input voltage drops below 7.5 VDC (+/- .25V) minus the dead band setting that is determined by SW1 dipswitch settings. These dipswitch settings apply for all eight inputs and outputs.
When SW1-1 is selected, 1 volt is added to the dead band. (Dead Band = +/- 1 volts)
When SW1-2 is selected, 2 volts are added to the dead band. (Dead Band = +/- 2 volts) (DEFAULT)
When SW1-1 and SW1-2 is selected, 3 volts are added to the dead band. (Dead Band = +/- 3 volts)
When SW1-3 is selected, 4 volts are added to the dead band. (Dead Band = +/- 4 volts)
When SW1-3 and SW1-1is selected, 5 volts are added to the dead band. (Dead Band = +/- 5 volts)
WCC III Technical Guide
The eight analog inputs on the WCC III V-Out Relay board must be wired to the eight analog outputs on the SAT III or SAT II controller in order for the V-Out mode to function. Also, the HSS connector must be connected to the SAT III HSS expansion port for power and ground connections to the SAT III controller, or a special two­wire power and ground pigtail must be provided for connection to 24VAC and GND to power the WCC III V-Out Relay board.

These analog inputs are set up as 0 to +15 DC Volts inputs. They should be connected to and mated up with the SAT III controller’s 8 Analog Outputs. These eight inputs are only used for the V-Out mode of operation, and are not needed for the Binary Output mode of operation.
GND Connection
This is an analog ground common connection point for VIN1 to VIN8 analog inputs. It is important that this “analog” ground on the WCC III V-Out RELAY board is connected to the Analog Input ground of the SAT III controller.
HSS Connectors
This is a 6-pin Mini-fi t connector that provides power and communications to the WCC III V-Out RELAY board from the SAT III controller. It is called an HSS port. The WCC III V-Out RELAY board requires 24 VAC and ground connections which are connected into these connector terminals. The WCC III V-Out RELAY board is generally powered by the same 24 VAC transformer that powers the satellite controller. Communications to the SAT III controller is also in this cable, along with a shield wire. The 6-pin HSS cable connections can also be daisy chained to other WCC III V-Out RELAY boards and WCC III Binary Inputs with Time Delay boards.

0 - 1, 0 – 5, 0 - 10 VDC, and Thermistor Type Sensors
The SAT III controller can accept a 0-1VDC, 0-5VDC, 0-10VDC, or THERM signal from a sensor. Since the SAT III controller is designed with eight settable analog input jumpers, these eight analog input jumpers must be correctly set for the type of input that is needed for the desired VDC across the load resistor to represent the full scale value of the analog input. On the older SAT II controller, the voltage from the 0-10 and 0-5 VDC sensors needed to be reduced before it reached the analog inputs of the older SAT II controller. This was accomplished by placing a line resistor in the circuit in addition to the load resistor.
“Older” 2-Wire Flush Mount Sensors
Wiring connections for the “older” 2-Wire Flush mount sensors is as follows: The “+V” terminal on the SAT III controller is a +12 VDC power source, and the ATI connection from the “older” 2-Wire Flush mount sensor is then connected to the SAT III ATI input(s). The temperature sensor is a current transducer which transmits a current proportional to the temperature it is sensing. The load resistor on the front of the SAT III controller is in series with the temperature sensor and connects the “ATI” terminal to the “GND” terminal. The satellite controller then monitors the voltage between the “ATI” terminal and “GND” on the SAT III controller to determine the temperature that is then sensed by the sensing element of the 2-wire Flush mount sensor. The SAT III controller could use either a 1-VDC or a 5-VDC input for the “older” 2-wire Flush mount sensor. With a 1-VDC input between “ATI” and “GND” to represent the 100 percent scale value on the Analog Input Screen, and 0 VDC represents the 0 percent scale value. The maximum allowable voltage across the load resistor is
1.2 volts. This is with the 0-1V analog input jumper installed. With the 0-5V analog input jumper installed, the satellite controller is designed for 5 VDC between “ATI” and “GND” to represent the 500 percent scale value on the Analog Input Screen, and 0 VDC represents the 0 percent scale value. The maximum allowable voltage across the load resistor is 5.2 volts with the 0-5V analog input jumper installed.
The specifi cations of the temperature sensor determine the value of the SAT III load resistor and the 0 percent and 100 percent scale value on the Analog Input Screen. The load resistors must be fi eld installed.
The older 2-wire air/water temperature sensor was used to monitor the temperature of the air in duct work or the temperature of fl uid in a pipe. For fl uid pipe applications, the probe may be removed from the transmitter, strapped to the pipe, and thermally insulated
from the ambient air. The transmitter should be mounted remotely by extending the two wires connecting the probe to the transmitter. The transmitter may be located up to 100 feet from the probe, or the sensor may be mounted in an immersion well with the use of thermal compound to ensure good thermal conduction between the water and the sensor. For chilled water sensing, it is highly recommended that the sensing element be removed from the transmitter (control head) to prevent condensation in the head.
The air/water sensor has two temperature ranges available, depending on which load resistor is used. A 100 ohm load resistor gives the sensor a control range of 30-120°F, and a 49.9 ohm load resistor gives the sensor a control range of 40-240 °F. This is with either the 0-1V or 0-5V analog input jumper installed. 100 percent scaling must be changed between the “Units @ 0% scale” and the “Units @ full scale” on the Analog Input Screen.
NOTE: These 2-wire based sensors are now considered
obsolete. When any 2-wire based sensor fails, a replacement thermistor type sensor is available for replacement for the SAT
III controller.
“Older” 3-Wire Voltage Type T emperature Sensors
The older 3-wire temperature sensors accomplish the same thing as the older 2-wire sensors, only you can think of the load resistor as being in the sensor and not at the satellite controller. The 3-wire sensor is wired to the “+V,” “ATI,” and “GND” terminals on the SAT III controller. The 3-wire sensor transmits a voltage between “ATI” and “GND” that directly corresponds to temperature, and therefore, a load resistor at the SAT III controller is not required when using a 3-wire voltage type sensor. 3 – wire sensors should not be used for long distance wiring, as wire length will affect the voltage coming back from the sensor. This voltage is again proportional to the temperature, so a 0.1 volt voltage drop is actually equivalent to a 10 deg °F error in temperature. 200 feet is about the maximum distance for a 3-wire sensor due to voltage drop of the small gauge wire (18 gauge and lower) that sensors are typically wired with.
NOTE: These 3-wire based sensors are now considered
obsolete, and when any 3-wire based sensor fails, a replacement thermistor type sensor is available for the SAT III controller.

4-to-20 Milli-Amp Current Sensors
4-to-20 Milli-Amp Current Sensors
The connection of a 4-to-20 milli-amp sensor to a SAT III controller will require simple math to determine the “Zero” point of the 4-to­20 milli-amp sensor. This is because the “Zero” point of the 4-to­20 milli-amp sensor is actually not at zero volts. This “Zero” point is actually at the 4 milli-amp point.
Various sensors that provide a 4-to-20 mA current output signal can be used with the SAT III controllers. The SAT III controllers are designed to work with a 4-to-20 milli-amp sensor to have either a +1VDC selected input scaling range or +5VDC selected input scaling range. The current that is measured across the load resistor(s) on the SAT III input at full scale (20mA) on either of the two input scaling range determines the load resistance value. Since the SAT III load resistor(s) will have at most a 20 milli-amp current going through them at full scale, and when the maximum input voltage of either +1VDC or + 5VDC that is required across the SAT III load resistor at 20 milli-amp. Therefore, when doing the required math at +1VDC input scaling range, a 4-20 mA sensor will require a 50 Ohm load resistor, and at a +5VDC input scaling range, a 4-20 mA sensor will require a 250 Ohm load resistor.
V 1 Volt R = --------- = ------------ = 50 Ohms I 0.020 Amps
V 5 Volts R = --------- = ------------ = 250 Ohms I 0.020 Amps
Both values of load resistors - the 50 Ohm (Actually 49.9 Ohm) & 250 Ohm are provided in the resistor pack kit that is provided with each new SAT III controller. The WattMaster part number of this kit is PL102029.
When programming the WCC III Analog Input Screen for a 4-20 mA sensor, the 100% scale value is the value represented when the sensor sends 20 mA to the SAT III controller, and the zero percent scale value is the value represented when the sensor sends 0 mA to the SAT III controller. For example, consider a 4-20 mA sensor which measures duct static pressure. The sensor provides 4 mA when the duct static pressure is 0 inches of water column and 20 mA when the duct pressure is 2 inches of water column. The 100 percent scale value on the Analog Input Screen is 2.00” W.C., and the zero percent scale value is -0.50” W.C.
The full scale value is fairly straightforward and very easy to understand. The zero percent scale value, on the other hand, is a bit more complicated. The following table shows the signal out of the sensor versus the duct static pressure.

20 2.00” W.C. 16 1.50” W.C. 12 1.00” W.C.

When programming the Analog Input Screen, the zero percent scale value is the value when 0 mA are supplied by the sensor. Since 0 mA represents -0.50” W.C., -0.50” W.C. is input for the zero percent scale value.
Thermistor Sensors
The Thermistor Flush mount sensor (WattMaster part # OE210) is connected to the “ATI”, and “GND” connections of the SAT III controller. A thermistor is a type of resistor with resistance that will vary according to its temperature. The SAT III controller is set up for 10K Type 3 thermistor sensors. The SAT III controller does all of the complex math to linearize the temperature versus voltage curve of the thermistor sensor. There is no calibration necessary for thermistor type sensors, but an offset is provided for the sensor on
the satellite analog input set-up screen. The 10K Type 3 Thermistor Flush Mount sensor is one of the most accurate room sensors on the market today for sensing basic room temperature, as the thermistor element is thermally isolated from the wall with a patented process developed by WattMaster Controls years ago.
There seems to be an almost endless supply of third-party sensors that use the 10K Type 3 thermistor as the sensing element. WattMaster Controls, Inc. can provide the following 10K Type 3 thermistor sensors:
2-Wire Thermistor Duct sensor with 6-inch probe (WattMaster part # OE230)
2-Wire Thermistor Duct sensor with 12-inch probe (WattMaster part # OE231)
Immersion well for 6-inch thermistor probe (WattMaster part # OE291)
2-Wire Thermistor Outside Air sensor (WattMaster part # OE250)
Figure 12-38: The WattMaster Controls, Inc. 10K Type 3 Flush Mount Sensor variations. Only the OE210 can be used with the SAT III controller. There are no connections or programming points on the SA T III controller for the additional slide pot (OE212, and OE213), or OVR switc h (OE211 and OE213). All of these 10K Type 3 Flush Mount sensors variations may be used with the RTU/TUC family of application-specifi c controllers.

GUIDE
Figure 12-40: SAT 3C Controller
The system architecture for the WCC III system interfacing with the TUC/RTU controllers through the SAT 3C is shown below:
The SAT3C - General Information (SS5004)
The SAT3C Controller has 8 status lights. The functions of these LEDs are listed below.
SAT REC - This LED will be lit when communications are being received by the SAT 3C Controller.
SAT XMIT - This LED will be lit when communications are being transmitted by the SAT 3C Controller.
TUC REC - This LED will be lit when communications are being received from the TUC/RTU RS-485 Communications Loop.
TUC XMIT - This LED will be lit when communications are being transmitted to the TUC/RTU RS-485 Communications Loop.
LOCAL SET - This LED will be lit when no communications with the WCC III-MCD has occurred in at least the last 2 minutes. This means that this SAT 3C communications loop is not communicating with the WCC III-MCD. All standalone setpoint control is dependent on the LOCAL SET parameters that are programmed into the SAT 3C controller by the user.
STATUS - This LED blinks for every second if SAT 3C is alive.
“C” MODE - This LED will be lit if this Controller is programmed as a SAT 3C and blinks for every internal calculation loop completion.
“D” MODE - This LED blinks for every second during power on delay and blinks every 8 seconds when watchdog is enabled.
SAT ADDRESS DIPSWITCH - There are two dipswitches on the cover of the SAT 3C controller, one dipswitch sets the address of the SAT 3C controller. The other dipswitch sets various local control options.

SA T 3C Controller
SA T 3C Controller - Connections points
All of the external SAT 3C connection points are single-tab ¼ inch Sta-Con connectors. With the exception of the TUC RS­485 communications connection which is a three-position, de­pluggable terminal block.
24V AC & GND Connection
Located on the bottom side of the SAT III controller is a 24 VAC and GND connection. This is the main power connection to the SAT 3C controller. Each SAT 3C Controller draws - 10VA. The GND connection points must be the same between all of the externally powered TUC/RTU boards and the SAT 3C Controller.
SA T Communica tion Connection
These connection points are for wiring of the SAT RS-485 communication loop. There are two “T” (Transmit) connections, two “R” (Receive) connections and two “SHIELD” connection points. There are two connection points provided for each connection for easy “daisy chaining” to the next Satellite Controller.
When connecting the RS-485 wiring from SAT III to SAT III or SAT 3C/D/F, or SAT 3P controller the wiring connections are as follows: connect “R” TO “R”, “T” TO “T”, AND “SHIELD” TO “SHIELD” OR “SH”. The RS-485 wire specifi cations are plenum rated jacketed stranded 18-gauge, 2-wire twisted pair with shield. 18-gauge stranded wire is mandatory to ensure a good connection with the ¼-inch Sta-Con connectors which are used to terminate the wires at the WCC III - MCD and at the satellite controllers.
TUC Communication Connection
These connection points are for wiring of the TUC RS-485 communication loop. There is a single three position, de-pluggable terminal block. Connect the wiring for the communications connections between the TUC/RTU’s as follows: “R” TO “R”, “T” TO “T”, AND “SHLD” TO “SHLD” OR “SH”. Connect the wiring from TUC/RTU controller to TUC/RTU controller. But, on the SAT 3C/D/F controller the TUC “R” connection must be wired to the SAT 3C/D/F “T” connection, and the SAT 3C/D/F controller “R” connection must be wired to the TUC “T” connection. The RS-485 wire specifi cations are plenum-rated jacketed stranded 18-gauge, 2-wire twisted pair with shield. 18-gauge stranded wire is mandatory to ensure a good connection between TUC/RTU controllers.

SA T 3C Addressing
Figure 12-41: SAT 3C Address Switch location
The address dip switches are additive; that is to say placing switches 4 and 5 in the ON position will cause the SAT 3C controller to be identifi ed as satellite controller number 24. The SAT 3C controller looks at the position of these switches only when it is going through its initialization process after being powered up. Simply changing the switch positions on a SAT 3C controller that is currently “on­line” will not change its address number. The switches need to be placed in the proper position before powering up the SAT 3C controller, or the SAT 3C must be powered down and then back up for the SAT 3C to “read” the new position of the switches. When placing the switches in the desired position, make sure the switch has “clicked” into place and is properly seated.
WCC III Technical Guide
There can be up to 29 SAT 3C controller connected together on a 2-wire communication loop. In order for the WCC III system to communicate properly with each SAT 3C, each SAT 3C must be assigned a separate address number. The number is assigned by positioning the small address dipswitch on the front of the SAT 3C in the proper position.
The SAT 3C uses up 8 satellite addresses. The lowest possible SAT 3C address is #8. The address must start in multiples of 8, starting at address # 8, then the next available address is #16, then next available address is #24, then next available address is #32, then next available address is 40, then next available address is 48, then next available address is 56, etc. The only legitimate SAT 3C address are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136, 144, 152, 160, 168, 176, 184, 192, 200, 208, 216, 224, and 232.

For example the following Satellite Addresses will not work as a SAT 3C starting address. 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 17, 18, 19, 20, 21, 22, 23, 25, 26, 27, 28, 29, 30, 31, 33, 34, 35, 36, 37, 38, 39, 41, 42, 43, 44, 45, 46, 47, 49, 50, 51, 52, 53, 54, 55, 57, 58, 59, 60, 61, 62, 63, 65, 66, 67, 68, 69, 70, 71,73, 74, 75, 76, 77, 78, 79, 81, 82, 83, 84, 85, 86, 87, 89, 90, 91, 92, 93, 94, 95, 97, 98, 99, 100, 101, 102, 103, 105, 106, 107, 108, 109, 110, 111, 113, 114, 115, 116, 117, 118, 119, 121, 122, 123, 124, 125, 126, 127, 129, 130, 131, 132, 133, 134, 135, 137, 138, 139, 140, 141, 142, 143, 145, 146, 147, 148, 149, 150, 151, 153, 154, 155, 156, 157, 158, 159, 161, 162, 163, 164, 165, 166, 167, 169, 170, 171, 172, 173, 174, 175, 177, 178, 179, 180, 181, 182, 183, 185, 186, 187, 188, 190, 191, 193, 194, 195, 196, 197, 198, 199, 201, 202, 203, 204, 205, 206, 207, 209, 210, 211, 212, 213, 214, 215, 217, 218, 219, 220, 221, 222, 223, 225, 226, 227, 228, 229, 230, 231, 233, 234, 235, 236, 237, 238, 239, and 240.
Care must be taken to ensure that two SAT 3C controllers do not have the same address. When this condition is present, the central computer (WCC III – MCD) does not know where to send the information, and the information which should be sent to the SAT 3C controller is then usually lost.
You should be aware of the symptoms that are caused by two satellite controllers having the same number. Let’s consider a new job in which the satellite controllers have not yet been programmed and 2 SAT 3C controllers are named number #8. When you call up satellite controller #8 to enter data, everything will appear to be ne. You will be able to enter data on the screens as if nothing is wrong. However, when you leave a screen and then return to the same screen, all of the data you entered will be missing. Also, if you fi nish programming the analog inputs for example, and then go to the analog input summary screen to review your inputs, all of the data you have entered will be missing.
Another situation that you might encounter is adding a SAT 3C controller to an existing system and accidentally giving it the same number as a SAT 3C presently “on-line.” Again, when you begin to program the new SAT 3C controller, everything will appear fi ne until you leave a screen or if you go to a summary screen. Only now, all of the data is usually not missing. Generally, you get parts of your data back and parts will be missing.
If you suspect you might have two SAT 3C controllers with the same address, number 8 for example, the best thing to do is go to the SAT 3C controller that you know is number 8, and remove the 2-wire RS-485 communication loop from it. Then go back to the computer and call up satellite controller #8. If the computer can still “talk” to satellite controller #8, then there is another satellite controller that is addressed #8 connected somewhere on the RS­485 communication loop.
If a satellite controller was accidentally addressed #8, there will be a satellite number missing. For example, if satellite controller #16 was mistakenly addressed to #8, satellite controller #16 will not be present. One way of telling which satellite controllers are
“on-line” is to go to the Satellite Summary Screen (see Section
3) and see which satellite controllers the computer recognizes as
being “on-line.”
If satellite controller #8 was accidentally misaddressed #16, there would not be a satellite controller at address #8, and the computer will give a “Non-Existing” message for satellite controller #8.
The other Dipswitch on the SAT 3C
Option 1, 2, and 3 Switches
For the SAT 3C, these Options switches do nothing, But on the SAT III controller the option 1 switch selects the A-to-D converter type that is on the mother board. With the switch turn OFF, the A-to-D curve is selected for the Maxim MAX147 part and with the switch turned “ON” for the TI-ADS7844 (BB marked) and the software will use the special A-to-D curve for the TI-ADS7844 part.
BA TT ON/OFF s witc h
This switch is used to turn the Battery (Rechargeable Super cap) ON and OFF to the SRAM located inside of the SAT 3C.
Local Set Switch
When the LOCAL dipswitch is in the ON position, the TUC/ RTU controllers will operate according to their predefi ned user programmed “local set” setpoints. That is, if the TUC/RTU controllers were programmed by the user to correctly operate when and if the WCC III - MCD is off-line or disconnected, but the SAT 3C controller is still present and communicating with the TUC/RTU controllers.
Local Set Disable Switch
When the LOCAL SET Disable dipswitch is in the ON position, the TUC/RTU controllers will operate according to their predefi ned user-programmed “On” setpoints. That is, if the TUC/ RTU controllers were programmed by the user to correctly operate when and if the WCC III - MCD is off-line or disconnected, but the SAT 3C controller is still present and communicating with the TUC/RTU controllers.
Test Switc h
The test mode is active only if the TEST dipswitch is in the ON position. The word “TEST” can be input as the binary value within the SAT 3C. Example of use would be if the user programmed

the word “TEST” into one of the control point values in the TUC/ RTU controller to check the operation of the TUC/RTU controllers with an alternate setpoint or schedule, then the user could place the TEST switch in the ON position to make this function work with out physically having to go back to the front-end computer to change a setpoint via the computer.
Addressing (Numbering) of the TUC/ RTU Controllers that are Connected to the SA T 3C
There can be up to a total of eight TUC-5R/5R+/5RX/RTU­17 controllers connected together on a local TUC RS-485 communication loop to the SAT 3C controller. The software that is written for each TUC/RTU controller is application specifi c, and must also be written for use with the WCC III system. In order for the SAT 3C to communicate properly with each individual TUC/RTU, each TUC/RTU must be assigned a separate address (number) from 1 to 8. This addressing or numbering is assigned by positioning the small dipswitch on each of the TUC/RTU boards in the proper position. The address switches are housed together in a block as shown below:
When the switch is in the “On” position, it represents the number on the right in the drawing below. That is, when switch #3 is “On” and all of the other switches are “Off,” the TUC is named #4. The switches are additive. That is to say, when switches 1 and 2 are “On,” the TUC is named #3.

SA T 3D Controller
SA T 3D – WCC III Interface to TUC/ RTU Controllers (SS5005)
The system architecture for the WCC III system interfacing with the TUC controllers through the SAT 3D is described below:
The SAT 3D - General Information
The SAT 3D Controller has 8 status lights. The functions of these LEDs are listed below.
SAT REC - This LED will be lit when communications are being received by the SAT 3D Controller.
SAT XMIT - This LED will be lit when communications are being transmitted by the SAT 3D Controller.
TUC REC - This LED will be lit when communications are being received from the TUC RS-485 Communications Loop.
TUC XMIT - This LED will be lit when communications are being transmitted to the TUC RS-485 Communications Loop.
LOCAL SET - This LED will be lit when no communications with the WCC III-MCD has occurred in at least the last 2 minutes. This means that this SAT 3D communications loop is not communicating with the WCC III-MCD. All standalone setpoint control is dependent on the LOCAL SET parameters that are programmed into the SAT 3D controller by the user.
SA T 3D Controller — Connections points
All of the external SAT 3D connection points are single-tab ¼­inch Sta-Con connectors. With the exception of the TUC RS­485 communications connection which is a three-position, de­pluggable terminal block.
24VA C & GND Connection
Located on the bottom side of the SAT 3D controller is a 24 VAC and GND connection. This is the main power connection to the SAT 3D controller. Each SAT 3D Controller draws - 10VA. The GND connection points must be the same between the all of the externally powered TUC boards and the SAT 3D Controller.
SAT Communica tion Connection
These connection points are for wiring of the SAT RS-485 communication loop. There are two “T” (Transmit) connections, two “R” (Receive) connections and two “SHIELD” connection points. There are two connection points provided for each connection for easy “daisy chaining” to the next Satellite Controller. When connecting the RS-485 wiring from SAT III to SAT III or SAT 3C/D/F, or SAT 3P controller the wiring connections are as follows: connect “R” TO “R”, “T” TO “T”, AND “SHIELD” TO “SHIELD” OR “SH”. The RS-485 wire specifi cations are plenum- rated jacketed stranded 18-gauge, 2 wire twisted pair with shield. 18-gauge stranded wire is mandatory to ensure a good connection with the ¼-inch Sta-Con connectors that are used to terminate the wires at the WCC III - MCD and at the satellite controllers.
STATUS - This LED blinks for every second if SAT 3D is alive.
“C” MODE - This LED blinks for every second during power on delay and blinks every 8 seconds when watchdog is enabled.
“D” MODE - This LED will be lit if this Controller is programmed as a SAT 3D and blinks for every internal calculation loop completion.
SAT ADDRESS DIPSWITCH - There are two dipswitches on the cover of the SAT 3D controller, one dipswitch sets the address of the SAT 3D controller, and the other dipswitch sets various local control options.
TUC Communication Connection
These connection points are for wiring of the TUC RS-485 communication loop. There is a single, three-position, de-pluggable terminal block. Connect the wiring for the communications connections between the TUC/RTU’s are as follows: “R” TO “R”, “T” TO “T”, AND “SHLD” TO “SHLD” OR “SH”. Connect the wiring from TUC/RTU controller to TUC/RTU controller. But, on the SAT 3C/D/F controller the TUC “R” connection must be wired to the SAT 3C/D/F “T” connection, and the SAT 3C/D/F controller “R” connection must be wired to the TUC “T” connection. The RS-485 wire specifi cations are a plenum-rated jacketed stranded 18-gauge, 2- wire twisted pair with shield. 18-gauge stranded wire is mandatory to ensure a good connection between TUC/RTU controllers.

There can be up to 59 SAT 3D controllers connected together on a 2-wire communication loop. In order for the WCC III system to communicate properly with each SAT 3D, each SAT 3D must be assigned a separate address number. The number is assigned by positioning the small address dipswitch on the front of the SAT 3D in the proper position.
The SAT 3D uses up to 4 satellite addresses locations. The lowest possible address is #4. The address must start in multiples of 4, starting at address # 4, then the next available address is #8, then next available address is #12, then next available address is #16, then next available address is 20, then next available address is 24, then next available address is 28, etc. The only legitimate SAT 3D addresses are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148, 152, 156, 160, 164, 168, 172, 176, 180, 184, 188, 192, 196, 200, 204, 208, 212, 216, 220, 224, 228, 232, and 236.
For example the following Satellite Addresses will not work as a SAT 3D starting address: 1, 2, 3, 5, 6, 7, 9, 10, 11, 13, 14, 15, 17, 18, 19, 21, 22, 23, 25, 26, 27, 29, 30, 31, 33, 34, 35, 37, 38, 39, 41, 42, 43, 45, 46, 47, 49, 50, 51, 53, 54, 55, 57, 58, 59, 61, 62, 63, 65, 66, 67, 69, 70, 71,73, 74, 75, 77, 78, 79, 81, 82, 83, 85, 86, 87, 89, 90, 91, 93, 94, 95, 97, 98, 99, 101, 102, 103, 105, 106, 107, 109, 110, 111, 113, 114, 115, 117, 118, 119, 121, 122, 123, 125, 126, 127, 129, 130, 131, 133, 134, 135, 137, 138, 139, 141, 142, 143, 145, 146, 147, 149, 150, 151, 153, 154, 155, 157, 158, 159, 161, 162, 163, 165, 166, 167, 169, 170, 171, 173, 174, 175, 177, 178, 179, 181, 182, 183, 185, 186, 187, 189, 190, 191, 193, 194, 195, 197, 198, 199, 201, 202, 203, 205, 206, 207, 209, 210, 211, 213, 214, 215, 217, 218, 219, 221, 222, 223, 225, 226, 227, 229, 230, 231, 233, 234, 235, 237, 238, 239, and 240.
Care must be taken to ensure that two SAT 3D controllers do not have the same address. When this condition is present, the central computer (WCC III – MCD) does not know where to send the information, and the information which should be sent to the SAT 3D controller is then usually lost.
You should be aware of the symptoms that are caused by two satellite controllers having the same number. Let’s consider a new job in which the satellite controllers have not yet been programmed and 2 SAT 3D controllers are named number #8. When you call up satellite controller #8 to enter data, everything will appear to be ne. You will be able to enter data on the screens as if nothing is wrong. However, when you leave a screen and then return to the same screen, all of the data you entered will be missing. Also, if you fi nish programming the analog inputs for example, and then go to the analog input summary screen to review your inputs, all of the data you have entered will be missing.
Another situation which you might encounter is adding a SAT 3D controller to an existing system and accidentally giving it the same number as a SAT 3D presently “on-line.” Again, when you begin to program the new SAT 3D controller, everything will appear fi ne until you leave a screen or if you go to a summary screen. Only now, all of the data is usually not missing. Generally, you get parts of your data back and parts will be missing.
If you suspect you might have two SAT 3D controllers with the same address, number 8 for example, the best thing to do is go to the SAT 3D controller that you know is number 8, and remove the 2-wire RS-485 communication loop from it. Then go back to the computer and call up satellite controller #8. If the computer can still “talk” to satellite controller #8, then there is another satellite controller that is addressed #8 connected somewhere on the RS­485 communication loop.

SA T 3D Addressing
If a satellite controller was accidentally addressed #8, there will be a satellite number missing. For example, if satellite controller #16 was mistakenly addressed to #8, satellite controller #16 will not be present. One way of telling which satellite controllers are
“on-line” is to go to the Satellite Summary Screen (see Section
3) and see which satellite controllers the computer recognizes as
being “on-line.”
If satellite controller #8 was accidentally misaddressed #16, there would not be a satellite controller at address #8, and the computer will give a “Non-Existing” message for satellite controller #8.
The Other Dipswitch on the SAT 3D
Option 1, 2, and 3 Switches
For the SAT 3D these Options switches do nothing, but on the SAT III controller the option 1 switch selects the A to D converter type that is on the mother board. With the switch turned OFF, the A-to-D curve is selected for the Maxim MAX147 part and with the switch turned “ON” for the TI-ADS7844 (BB marked), the software will use the special A-to-D curve for the TI-ADS7844 part.
BA TT ON/OFF s witc h
This switch is used to turn the Battery (Rechargeable Super cap) ON and OFF to the SRAM located inside of the SAT 3D.
Local Set Switch
When the LOCAL dipswitch is in the ON position, the TUC controllers will operate according to their predefi ned user programmed “local set” setpoints. That is, if the TUC controllers were programmed by the user to correctly operate when and if the WCC III - MCD is off-line or disconnected, but the SAT 3D controller is still present and communicating with the TUC controllers.
Local Set Disable Switch
When the LOCAL SET DIS dipswitch is in the ON position, the TUC controllers will operate according to their predefi ned user programmed “On” setpoints. That is, if the TUC/RTU controllers were programmed by the user to correctly operate when and if the WCC III - MCD is off-line or disconnected, but the SAT 3D controller is still present and communicating with the TUC controllers.
Test Switc h
The test mode is active only if the TEST dipswitch is in the ON position. The word “TEST” can be input as the binary value within the SAT 3D. Example of use would be if the user programmed the word “TEST” into one of the control point values in the TUC controller to check the operation of the TUC controllers with an alternate setpoint or schedule, the user could then place the TEST switch in the ON position to make this function work without physically having to go back to the front-end computer to change a setpoint via the computer.

TUC Controllers to SAT 3D Addressing
Addressing (Numbering) of the TUC controllers that are connected to the SAT 3D
There can be up to a total of thirty-two TUC-2R or TUC­5R/5R+/5RX controllers connected together on a local TUC RS­485 communication loop to the SAT 3D controller. The software that is written for each TUC controller is application-specifi c, and must also be written for use with the WCC III system. In order for the SAT 3D to communicate properly with each individual TUC, each TUC must be assigned a separate address (number) from 1 to
32. This addressing or numbering is assigned by positioning the small dipswitch on each of the TUC boards in the proper position. The address switches are housed together in a block as shown in Figure 12-46.
When the switch is in the “On” position, it represents the number on the right in the drawing below. That is, when switch #3 is “On” and all of the other switches are “Off,” the TUC is named #4. The switches are additive. That is to say, when switches 1 and 2 are “On,” the TUC is named #3.

SA T 3F Controller
SA T 3F – WCC III Interface to TUC/ V AVZ II Controllers (SS5016)
The system architecture for the WCC III system interfacing with the TUC controllers through the SAT 3F is described below:
The SAT 3F - General Information
The SAT 3F Controller has 8 status lights. The functions of these LEDs are listed below.
SAT REC - This LED will be lit when communications are being received by the SAT 3F Controller.
SAT XMIT - This LED will be lit when communications are being transmitted by the SAT 3F Controller.
TUC REC - This LED will be lit when communications are being received from the TUC RS-485 Communications Loop.
TUC XMIT - This LED will be lit when communications are being transmitted to the TUC RS-485 Communications Loop.
LOCAL SET - This LED will be lit when no communications with the WCC III - MCD has occurred in at least the last 2 minutes. This means that this SAT 3F communications loop is not communicating with the WCC III - MCD. All standalone setpoint control is dependent on the LOCAL SET parameters that are programmed into the SAT 3F controller by the user.
SA T 3F Controller — Connections points
All of the external SAT 3F connection points are single-tab ¼­inch Sta-Con connectors. With the exception of the TUC RS­485 communications connection which is a three-position, de­pluggable terminal block.
24VA C & GND Connection
Located on the bottom side of the SAT 3F controller is a 24 VAC and GND connection. This is the main power connection to the SAT 3F controller. Each SAT 3F Controller draws - 10VA. The GND connection points must be the same between the all of the externally powered TUC boards and the SAT 3F Controller.
SAT Communica tion Connection
These connection points are for wiring of the SAT RS-485 communication loop. There are two “T” (Transmit) connections, two “R” (Receive) connections and two “SHIELD” connection points. There are two connection points provided for each connection for easy “daisy chaining” to the next Satellite Controller. When connecting the RS-485 wiring from SAT III to SAT III or SAT 3C/D/F, or SAT 3P controller the wiring connections are as follows: connect “R” TO “R”, “T” TO “T”, AND “SHIELD” TO “SHIELD” OR “SH”. The RS-485 wire specifi cations are plenum- rated jacketed stranded 18-gauge, 2 wire twisted pair with shield. 18-gauge stranded wire is mandatory to ensure a good connection with the ¼-inch Sta-Con connectors that are used to terminate the wires at the WCC III - MCD and at the satellite controllers.
STATUS - This LED blinks for every second if SAT 3F is alive.
“C” MODE - This LED blinks for every second during power on delay and blinks every 8 seconds when watchdog is enabled.
“D” MODE - This LED will be lit if this Controller is programmed as a SAT 3F and blinks for every internal calculation loop completion.
SAT ADDRESS DIPSWITCH - There are two dipswitches on the cover of the SAT 3F controller, one dipswitch sets the address of the SAT 3F controller, and the other dipswitch sets various local control options.
TUC Communication Connection
These connection points are for wiring of the TUC RS-485 communication loop. There is a single, three-position, de-pluggable terminal block. Connect the wiring for the communications connections between the TUC/VAVZ II’s are as follows: “R” TO “R”, “T” TO “T”, AND “SHLD” TO “SHLD” OR “SH”. Connect the wiring from TUC/VAVZ II controller to TUC/VAVZ II controller. But, on the SAT 3C/D/F controller the TUC “R” connection must be wired to the SAT 3C/D/F “T” connection, and the SAT 3C/D/F controller “R” connection must be wired to the TUC “T” connection. The RS-485 wire specifi cations are a plenum-rated jacketed stranded 18-gauge, 2- wire twisted pair with shield. 18-gauge stranded wire is mandatory to ensure a good connection between TUC/VAVZ II controllers.

Addressing the SAT3F
Figure 12-48: SAT 3F Address Switch location
The address dip switches are additive; that is to say placing switches 4 and 5 in the ON position will cause the SAT 3F controller to be identifi ed as satellite controller number 24. The SAT 3F controller looks at the position of these switches only when it is going through its initialization process after being powered up. Simply changing the switch positions on a SAT 3F controller that is presently “on­line” will not change its address number. The switches need to be placed in the proper position before powering up the SAT 3F controller, or the SAT 3F must be powered down and then back up for the SAT 3F to “read” the new position of the switches. When placing the switches in the desired position, make sure the switch has “clicked” into place and is properly seated.
For example the following Satellite Addresses will not work as a SAT 3F starting address: 1, 2, 3, 5, 6, 7, 9, 10, 11, 13, 14, 15, 17, 18, 19, 21, 22, 23, 25, 26, 27, 29, 30, 31, 33, 34, 35, 37, 38, 39, 41, 42, 43, 45, 46, 47, 49, 50, 51, 53, 54, 55, 57, 58, 59, 61, 62, 63, 65, 66, 67, 69, 70, 71,73, 74, 75, 77, 78, 79, 81, 82, 83, 85, 86, 87, 89, 90, 91, 93, 94, 95, 97, 98, 99, 101, 102, 103, 105, 106, 107, 109, 110, 111, 113, 114, 115, 117, 118, 119, 121, 122, 123, 125, 126, 127, 129, 130, 131, 133, 134, 135, 137, 138, 139, 141, 142, 143, 145, 146, 147, 149, 150, 151, 153, 154, 155, 157, 158, 159, 161, 162, 163, 165, 166, 167, 169, 170, 171, 173, 174, 175, 177, 178, 179, 181, 182, 183, 185, 186, 187, 189, 190, 191, 193, 194, 195, 197, 198, 199, 201, 202, 203, 205, 206, 207, 209, 210, 211, 213, 214, 215, 217, 218, 219, 221, 222, 223, 225, 226, 227, 229, 230, 231, 233, 234, 235, 237, 238, 239, and 240.
Care must be taken to ensure that two SAT 3F controllers do not have the same address. When this condition is present, the central computer (WCC III – MCD) does not know where to send the information, and the information which should be sent to the SAT 3F controller is then usually lost.

TUC-2R and Four R elay Expansion Board
Figure 12-50: TUC-2R Controller – Current version
The current TUC-2R controller is an application-specifi c controller. Please see the application-specifi c manual for the exact input and output confi guration for the specifi c application that you are controlling. This current TUC-2R controller is generally used to control only VAV box control. The number -2R derives from the fact that there are a total of 2 relay outputs on this circuit board. Also included on the TUC-2R is the expansion port for additional input and output control. Typical common applications of this TUC-2R controller are as follows: complicated VAV box control such as series/parallel fan-powered boxes with reheat and both pressure dependent or pressure independent operations. WattMaster Controls has an extensive standard library of application-specifi c software that has been developed over the years for this TUC-2R controller. WattMaster Controls can and will write application­specifi c software to your written specifi cations, for a nominal cost. This is usually done to satisfy a specifi c customer requirement.

This Four Relay Expansion Board uses an 8-position modular plug to connect to the TUC-2R controller.
The Four Relay Expansion Board is an expansion board for the TUC-2R controller. It provides a means to add 4 additional output relays to the TUC-2R controller. Again, control of these relays is application specifi c, meaning that the software code in the TUC- 2R must have been written to support the Four Relay Expansion Board. This board is typically used to control pilot duty relays that control Series Fan, Parallel Fan, up to 2 stages of Box heat, and external Strip Heat.

Nice becomes useful when there are several processes that are demanding more resources than the WCC III – MCD CPU can provide. In this state, a higher priority process will get a larger chunk of the WCC III – MCD CPU time than a lower priority process. If the WCC III – MCD CPU can deliver more resources than the processes are requesting, then even the lowest priority process can get up to 99% of the WCC III - MCD CPU. Only the superuser (root) may set the niceness to a smaller (higher priority) value. On Linux it is possible to change ”/etc/security/limits.conf “ to allow other users or groups to set a low nice value.
Idle: Percentage of the WCC III – MCD CPU’s time that the CPU were idle and the system did not do an outstanding disk I/O request. A computer processor is described as idle when it is not being used by any program.
Programs which make little use of the CPU Idle Time mean that they run at a low priority so as not to impact programs that run at normal priority like BackTask.exe. Many programs that use the WCC III – MCD CPU idle time can cause the WCC III - MCD CPU to always be 100% utilized, so that the time spent where the WCC III – MCD CPU would have been idle is instead spent performing useful computations. This generally causes the WCC III – MCD CPU to consume more power as most modern computer’s CPUs can enter power-save modes when they are idle.

Nice: Percentage of the WCC III – MCD CPU’s utilization that occurred while executing at the user level.
Nice (pronounced /na is/) is a program that’s found within Linux. Nice directly maps to a kernel call of the same name. For any given process, it changes the priority in the kernel’s scheduler.

The WCC III - MCD
The WCC III - MCD
Overview
The WCC III – MCD was converted from the Windows XP operating system over to the Ubuntu version of Linux using the command line interface only and was then released by WattMaster Controls in October of 2009. The main function of the WCC III – MCD is to provide a hardware and software platform for a program that WattMaster Controls has developed that is called “BACKTASK.exe”. The BACKTASK.exe program is a multiple BACKground TASKing application program.
BACKTASK.EXE (SS5009)
The BACKTASK.exe program performs many functions such as:
USB communications to the internal MCOMM board
Time clock functions
Analog/binary global processing
Overrides of control points
• Holiday scheduling
• Optimal starts
• PID programs
Shed /Restore programs
Duty cycle programs
• Proportional Programs
• Tenant Overrides
Emailing of alarms
The BACKTASK.exe program also provides for remote IP connection to a set of windows-based programs generally referred to as the WCC III programs. This WCC III – MCD also has hardware (WCCIII MCOMM board) that interfaces to a RS-485 communications loop that connects to SAT III type controllers for building automation controls.
Watchdog Circuit/P ow er F ail
If the BACKTASK.exe program is not running on the WCCIII
- MCD, there is a watchdog circuit that will restart the WCCIII – MCD. This watchdog circuit may interfere with the installation of new BACKTASK.exe software. There is a way to disable this watchdog circuit. Please contact WattMaster Controls for further information on temporarily disabling this watchdog circuit. In addition to this watchdog circuit, there is a small wall wart 24vac transformer that must be connected to 120VAC or else the WCCIII
- MCD will restart every two minutes. This is part of the power fail design circuit of the WCC III – MCD. This transformer is meant to
be plugged into a (NON – UPS) 120VAC outlet. The power cord for the WCC III – MCD is to be connected to a dedicated UPS (Uninterruptible Power Supply) outlet so that the MCD will keep running during a minor power outage. The Cable/DSL modem/ router should also be plugged into one of these dedicated UPS (Uninterruptible Power Supply) outlets.
MCD-Menu Program Overview
WattMaster Controls has developed a simple setup installation program for the Linux command line interface, and this program is called mcd-menu. Prior knowledge of Linux is not required, but would be helpful. This mcd-menu program has eleven subprograms incorporated into it that will allow for the following operations to be preformed:
The setup of the Network IP Confi guration of the
WCC III – MCD network card interface
Copying of the BackTask specifi c data fi les to the
root of the USB Drive
Restoring of the BackTask specifi c data fi les from
the root of the USB Drive
The resetting of the WCC III - MCD IP address
back to the WattMaster factory Default IP Address settings
The resetting of the WCC III - MCD DNS settings
back to the WattMaster factory default DNS settings
The restarting of the 2 by 20 line LCD Driver that
is located on the front of the WCC III – MCD
The restarting of the 2 by 20 line LCD Display that
is located on the front of the WCC III – MCD
The testing of the Internet Connection, from the
WCC III - MCD to the internet
The testing of DNS Settings, from the WCCIII –
MCD to the internet
The shutdown of the WCC III - MCD – properly
closing down
The shutdown and restart of the WCC III - MCD
The Webmin access method can also accomplish all of these same tasks, but is a little bit harder to use and is meant to be more of an “off site” management tool for the WCC III - MCD. The mcd­menu program is meant to be used as the initial IP setting tool and BACKTASK data fi le loading tool for the WCC III - MCD. For this a monitor and keyboard needs to be connected temporarily just for the initial IP setup and BACKTASK data fi le loading.

Overview
The default administration username is wcciii and the password is wt@@58 This user name and password are both CAP sensitive, and should be entered in lower case letters only.
1. Type “mcd-menu” at the wcciii@wcciii-mcd:~$ prompt (view only – restricted access). You can perform very few functions as “View only restricted access”, such as Copy/restore WCCIII data fi les.
2. To do the root level tasks like confi gure IP address, shutdown the WCC III - MCD, reboot the WCC III - MCD, reset the WCC III – MCD IP addresses and DNS settings to DEFAULT confi gurations, and of course, copy/restore WCCIII data fi les, you must be signed in as a “root” user. You must be very careful signed in as a root user because you can render your WCC III - MCD system unable to communicate with the outside world if improperly used.
If you have selected a command and you are signed in as a root user, it will give you a warning message as listed below:
************************************************** * * * Warning: The program is not running as root. * * Interface confi gurations or saving may fail! * * * **************************************************
NOTE: DO NOT run the mcd-menu program from inside

You can enter more than one IP address here, a primary and a secondary, and please note that they must be separated by a space. For example, on the Internet there exists a special case of nameservers lookup sites, the so called Domain Name System (DNS) servers, which are used to translate a static hostname or a domain name (for example, ‘WCC-CONTROLS.com’) to its corresponding binary identifi er (the IP address 76.12.37.232), or vice versa.

Copy BackT ask da ta Files to USB Drive (Choice #2)
This sub program will copy all of the useful WCC III data fi les to a USB drive (User / Contractor provided), assuming that there is a USB drive plugged into the USB port on the WCC III – MCD. It will copy all of these fi les to the root of the USB drive.
If there is not a USB hard drive in the USB port on the front of the WCCIII – MCD, this program assumes that there is a USB drive there even if it is not there. It will not report that there is a drive reading or writing error or any other errors. So when backing up, make sure that there is a USB hard drive in the USB socket port on the front of the WCCIII – MCD, and also there should be a LED on this USB hard drive that should light up when data is written or read from it. Please verify that this LED operates when backing up data to this USB hard drive.
