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.
• WCC III software package – Provided on a
CDROM, or is available via a download on the
WCC Controls website: www.wcc-controls.com.
The installation CDROM contains the following
programs:
• A DSL or Cable router/switch that connects to the
internet, or access to the internet via some other
method. 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 may not be possible.
* NOTE: The TenantOverride.exe program is also available
as a single program installation for the end users that are using
the simplistic graphical interface of the TenantOverride.exe
screen to locally turn on and off specifi c control points that are
applicable to the end user.

12. WCC III 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 fi 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
fi 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.

GUIDE
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
fi 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.

GUIDE
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
fi 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.

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.

Old SA T II Type Binary Input with Time Delay Board
The “Old” SAT II T ype Binary Input with

All external connections to the ‘old” SAT II type Binary Input
with Time Delay board connection points are non de-pluggable
screw-cage type of wire-clamped based terminal blocks. 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.

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.

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.

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
The connection of a 4-to-20 milli-amp sensor to a SAT III controller

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.

Thermistor Sensors
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

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

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

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.
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
fi 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

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.

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.

SA T 3F Addressing
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.
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.
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 3F controllers are named number #8. When you call up
satellite controller #8 to enter data, everything will appear to be
fi 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.
There can be up to 59 SAT 3F controllers connected together on
a 2-wire communication loop. In order for the WCC III system to
communicate properly with each SAT 3F, each SAT 3F must be
assigned a separate address number. The number is assigned by
positioning the small address dipswitch on the front of the SAT 3F
in the proper position.
The SAT 3F 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
3F 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.
WCC III Technical Guide
Another situation which you might encounter is adding a SAT 3F
controller to an existing system and accidentally giving it the same
number as a SAT 3F presently “on-line.” Again, when you begin
to program the new SAT 3F 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 3F controllers with the
same address, number 8 for example, the best thing to do is go to
the SAT 3F 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.

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.

Program (SS5021)
The WCC3.exe shortcut icon should have been
installed on your WCC III Front end computer
desktop with the WCC III Installation Software
CD. The WCC III Installation Software CD is
WattMaster Controls Part # DM1WC011-01X.
To start the WCC3.exe program, double-click the left mouse button
on the Shortcut Icon on the Windows desktop.
After a short period of time, dependent upon the CPU speed of your
Windows based computer and the speed of your IP connection to
the internet, the WCC III T ype Connection Dialog Box will appear.
Server IP Address:
This is the static IP address of the WCC III – MCD. An IP Address
is like a phone number on the world wide web. The IP address for
the WCC III – MCD must be Static (does not change) as opposed
to Dynamic (constantly changing). This static IP address must be
provided by your internet service provider. (A static IP address
is the preferred IP connection method for the WCC III system to
function.) If you actually know the static IP address of the WCC
III – MCD that you wish to connect to, please enter it here in the
Server IP Address fi eld, or better yet, continue to the Remote Access Dialog Window by selecting the
You can use a Dynamic IP Address with the WCC III – MCD,
but you must then have what is called a static “Host Name”. This
static “Host name” must then be provided by your internet service
provider and is limited to 58 total characters.
Port Number:
The WCC3.exe program opens a two-way, secure communications
port that then allows for communication between WCC III – MCD
and the WCC3.exe program that is running on the WCC III Front
end computer. This IP Address connection is done on a higher
address port number than normal (WCC III connection is port
number 39289) to help reduce the risk of computer hacking.

This connection to the WCC III Main Menu is not an actual IP
connection, but rather a “dummy” WCC III main menu screen
window with no values. This “dummy” WCC III main menu
screen window will allow you to view and see what the actual
WCC3.exe screens will look like – minus any data.
In the Set Password Dialog Screen, enter an “Operator:”
identifi cation and a “Code:” or password equal to at least a pass
level 0 that has been previously set up on the WCCIII System Parameter – Operator Code Screen. (See the Operator Code
Screen of the System Parameter Screen in Section 3 for information
on setting up Operator Codes.) Click
“Current Pass Level:” stays at 0 or higher (1, 2, or 3), and then
click
<OK>. By selecting <OK>, the WCC3.exe program will now
start to connect to the selected WCC III – MCD via this selected
IP address connection. It should bring up the WCC III Main Menu Screen within a new window. If the “Current Pass Level:” changes
to –1, then you do not have access to the WCCIII – MCD. If you
do not have access to the WCCIII – MCD and you click
then this connection to the WCC III Main Menu is not an actual
IP connection, but rather a “dummy” WCC III main menu screen

An Internet Protocol (IP) address is a numerical identifi cation
and logical address that is assigned to the WCC III – MCD that is
participating in a computer network that is then utilizing the Internet
Protocol for communication between its nodes. The WCC III MCD is confi gured to use the same IP address each time it powers
up - this is known as a Static IP address. In contrast, in situations
when the other computer’s IP address is assigned automatically,
it is known as a Dynamic IP address. The Static IP addresses are
manually assigned to the WCC III - MCD by an administrator.

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 (pronounced /na is/) is a program that’s found within Linux.
Nice directly maps to a kernel call of the same name. For any

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.
