System Overview

INTRODUCTION: SYSTEM
OVERVIEW

____________________________________________________

The ECC/WCC II is a microprocessor based energy management
and temperature control system designed to minimize the energy
usage of a building and maximize the occupant comfort.The ECC/
WCC II system provides the building owner with a means of
monitoring and controlling building mechanical systems from one
central location. The ECC/WCC II system provides computerized
control of building mechanical systems, but requires no computer
experience to operate or program the system.

Diagram of WCCII System

The “front end” of the ECC/WCC II system consists of a personal
computer with custom communication boards. See Diagram that
follows. The computer is referred to as the Central Processing
Unit (CPU), and the computer, keyboard, monitor (screen), printer
(optional), and modem (optional) together are referred to as the
Operator Control Console. The CPU communicates with the
remote satellite controllers using a two-wire communication loop.

Operator Interfaces

I-1

WCC II Operator’s Guide

System Overview

Operator Control Console
Components

The building operator monitors and controls the building
mechanical systems from one central location called the Operator
Control Console. The Operator Control Console consists of the
following components:

1. Central Processing Unit (CPU)

2. Keyboard

3. Monitor (CRT)

4. Printer (optional)

5. Modem (optional)

Central Processing Unit

A personal computer with custom communication boards acts as
the Central Processing Unit (CPU) which communicates with the
remote mounted satellite controllers via a two wire communication
loop.

The personal computer is dedicated to the ECC/WCC II system
and cannot be used for other functions. The use of hardware
accessories with the ECC/WCC II CPU that is not specifi cally
approved in writing by WattMaster Controls Group will void the
warranty on the ECC/WCC II system. The use of software other
than that furnished with the ECC/WCC II system may result in
system malfunction. WattMaster Controls Group is not responsible
for a system failure so generated.

Monitor

Note: We highly recommend that you only use the number

keys along the top of the keyboard while entering numeric

values and use the keypad ONLY for cursor control on the

ECC/WCC II system.

Printer

The on-site printer allows the operator to print status or schedule
summaries, a permanent record of entered programs, and trend
logging reports. The printer will automatically print alarms as they
occur, print operator ID as the user signs on and off the system,
and print any overrides that are entered.

Satellite Controller

The satellite controllers are fi eld mounted, microprocessor based
units which provide direct digital control of building mechanical
systems. The satellite controllers receive operating instructions
from the CPU, but once they are programmed, they have the
“brains” to monitor and control building mechanical systems
independently of the CPU. If communication from the CPU to
the satellite controllers is broken, the satellite controllers will
continue to control at programmable setpoints. In the event of a
primary power failure, the satellites will retain both their operating
instructions and accumulated data in battery backed memory.

The three versions of the satellite controller that will communicate
with the ECC/WCC II system are the SAT II, SAT II-A, and SAT
II-B.

The monitor resembles a television and displays computer data in
text on its cathode ray tube (CRT), or screen.

Keyboard

The keyboard is arranged like a typewriter to allow manual entry
of data and programs. We suggest that you fi rst become familiar
with the keyboard before attempting to operate the system. Refer
to the owner’s manual supplied with your computer for additional
keyboard information.

Operator Interfaces

WCC II Operator’s Guide

System Overview

SAT II

Sensors and relays etc. are wired to the SAT II controller to allow
it to monitor and control loads directly. Each SAT II controller can
handle the following number of inputs and outputs:

8 analog or binary inputs

•

•

16 additional binary inputs

- 1 binary input board receives 8 binary inputs

- 2 binary input boards may be used with one
SAT II

8 analog outputs (0-15 VDC maximum range)

•

- 1 DAC module enables 4 analog outputs

- 2 DAC modules may be installed in SAT II

- Any or all of the 8 analog outputs may be
converted to binary outputs using 1 V-Out
to Binary board

- 1 chip switch is required for each binary
output

•

16 binary outputs

- 1 chip switch is required for each binary
output

SAT II-A

The SAT II-A is a version of the satellite controller that allows the
ECC/WCC II front end computer to communicate with remote
mounted Terminal Unit Controllers.

The Terminal Unit Controller (TUC) is a microprocessor based
device which can be used to control terminal units such as pressure
dependent variable air volume (VAV) boxes, pressure dependent
fan power boxes, fan coil units, heat pumps etc. The TUC can be
used as a stand-alone controller, or the TUC can be used with the
ECC/WCC II system.

The TUC accepts an input from a room temperature sensor to allow
it to monitor the space temperature and when used with the SA
(Stepper Actuator) actuator, provides pressure dependent control
of the primary air damper on terminal units such as variable air
volume boxes, constant fan power induction units, and intermittent
fan power induction units. The SA Actuator is not an integral
part of the TUC and must be ordered and purchased separately.
The TUC can also have three relay outputs to provide control of
the fan and fi rst and second stages of heat on fan terminal units,
or to control the fan, compressor, and reversing valve on a heat
pump. The TUC can also provide an output to control two 24 VDC
solenoid air valves to obtain “feed” and “bleed” type control of
pneumatic controlled devices. The TUC is generally mounted at
the terminal unit (i.e. VAV box, heat pump, etc.).

When the TUC’s are to be used with the ECC/WCC II system,
a type SAT II-A satellite controller is required as the interface
between the Central Processing Unit (CPU) and the Terminal Unit
Controller (TUC). The SAT II-A is a special version of the satellite
controller, and its only purpose is to interface with the TUC’s. Up
to 32 TUC’s can be connected to one SAT II-A using a 3-wire,
shielded cable. The TUC’s are wired to the SAT II-A in a “daisy
chain” arrangement. That is to say, the 3-wire cable does not have
to be run from each TUC back to the SAT II-A. The 3-wire cable
is run from the SAT II-1 to the nearest TUC and the 3-wire cable is
extended from that TUC to the next.

TUC Input/Output Features

The fi ve versions of the pressure dependent TUC are shown in the
table that follows:

Model TUC Description

TUC-R 3 Relays with 2 amp, 24 Volt SPDT Contacts

TUC-A Stepper Motor Actuator Output

TUC-AR Stepper Motor Actuator Output & 3-24 Volt

SPDT Relays

TUC-P Pneumatic Output

TUC-PR Pneumatic Output & 3-24 Volt SPDT Relays

Note: The SA actuator and solenoid air valves must be

ordered and purchased separately.

SAT II-B

The SAT II-B is similar to the SAT II-A, only the SAT II-B
communicates with up to 32 TUC-VR’s.

The TUC-VR is a velocity resetting (pressure independent)
controller for use with variable air volume (VAV) terminal units.
The TUC-VR mounts on the VAV box and communicates with
the front end ECC/WCC II through a SAT II-B. The TUC-VR
provides precise direct digital control of the following types of
VAV terminal units:

1-Cooling Only

2-Cooling/Staged Electric Reheat

3-Cooling/Time Proportioning Electric Reheat

4-Cooling Proportional Reheat Valve

5-Parallel Fan Powered/No Reheat

Optional Enhanced Color Graphics

The Enhanced Color Graphics option allows the ECC/WCC II
system to display up to 60 color graphic pictures in the same front
end computer that acts as the ECC/WCC II CPU. The color graphic
pictures can be drawn using nearly any color graphics package,
and once the picture is displayed on the screen, a “snap-shot” of
the picture is captured and used as the background picture on the
Enhanced Color Graphics Screen. Dynamic analog and binary
values are then placed on the screen to allow the user to see actual
temperatures, status, etc. in the proper place on the picture.

When ordering the Enhanced Color Graphics option, a WCC II with
a 20MB hard disk, an EGA card, and color monitor is required as
the front end computer along with the additional Enhanced Color
Graphics software and a graphics package such as PC Paintbrush.

Optional Tenant Override

The Tenant Override Feature allows the occupants in the building
to call the ECC/WCC II system on the telephone and cause the
lights and/or heating and/or cooling equipment to control according
to their occupied (daytime) control scheme. The system has the
capability of overriding the control for 500 zones.

The ECC/WCC II system will “talk” to the tenant using an artifi cial
voice, and the user instructs the ECC/WCC II system by pressing
the numbers on the telephone.

A summary report of which tenants used the telephone override
system is available for billing purposes. A separate telephone line
is required for the Tenant Override Feature.

System Size

The central processing unit is capable of communicating with up
to 240 SAT II controllers. The front end ECC/WCC II considers
each SAT II-A or SAT II-B as 4 SAT II controllers. The equivalent
number of satellite controllers must be under 240.

A system with 240 satellite controllers is capable of handling up to
11520 points, a point being a hard wired input or output.

Modular Construction

Equipment cost is reduced because the system, including the satellite
controllers, is modular. Only the number of satellite controllers
required for the job are purchased, and only the required number of
outputs are purchased for the satellites. Installation cost is reduced
because “global” information gathered at one satellite can be shared
with other satellites, eliminating costly intermediate controls.

Analog Inputs

An analog input is a numerical value (signal) sent to the SAT II
controller to allow monitoring of space temperatures, duct pressures
etc. The SAT II controller can accept 8 analog inputs which
are named, A1-A8. (Note: A1-8 may be either analog or binary
inputs.) On certain screens (such as Global Analog Screens), you
must indicate the satellite controller number along with the channel
on the satellite controller. For example, 12A2 means analog input
number 2 on satellite controller #12.

The analog inputs are usually wired to the “+V” and “ATI” (Actual
Temperature In) terminals on the SAT II controller (three wire
sensors are wired to the “GND” terminal also.) The “+V” terminal
on channels 1-7 are a 12 VDC power source. The “+V” terminal
on channel 8 provides either 12 VDC or 18 VDC depending on
the position of the jumper under the cover near channel 8. To get
12 VDC from the “+V” terminal on channel 8, the jumper must
connect the A and B terminals. To get 18 VDC, the jumper must
connect the B and C terminals.

A 20 mA sensor can be used on up to 5 channels on the SAT II
controller. The total current for all 8 analog inputs must be kept
under 115 mA.

Binary Inputs

A binary input is an On/Off (dry contact closure) signal sent to
the SAT II controller to allow monitoring of air fl ow switches,
switch settings, etc. The SAT II controller comes standard with
16 small toggle switches on its front panel labeled, L1-L16 which
are in effect manually controlled binary inputs. The ECC/WCC II
monitors the On/Off status of these switches and can control and/or
alarm based on the position of these switches. The binary input
board(s) allow the manual toggle switches to be replaced with a
terminal strip which accepts wiring from remote mounted binary
input devices.

The SAT II controller has two sets of 8 small toggle switches on its
front cover labeled L1-L16. Switches L1-L8 are housed together in
one module, and switches L9-L16 are housed together in another
module. One module of switches is removed for each binary input
board and replaced with a ribbon cable which connects the binary
input board to the SAT II controller. The binary devices to be
monitored are then wired to the terminal strip of the binary input
board. The binary input board requires a 24 VAC power supply.

Analog Outputs

An analog output is a variable DC voltage signal sent from the
satellite controller used for proportional control of devices with
modulating actuators. The analog outputs are wired to the “V-Out”
and “Gnd” terminals on the SAT II controller and are named P1­P8. The P stands for Proportional Output.

The SAT II controller has the capability of providing 8 analog
output signals which have a maximum range of 0-15 VDC. If the
analog outputs are to be used, V-Out modules must be purchased
and are fi eld installed. One V-Out module is required for 4 analog
outputs, and two V-Out modules can be installed in one satellite
controller to allow one satellite controller to provide up to eight
analog outputs.

Each analog output has a limit of 15 mA. The total current output
of all 8 analog outputs must be kept under 115 mA.

Note: Later versions of the satellite controllers require two

modules for each set of four analog outputs. On these models,

sockets U-9 and U-10 activate outputs 1-4, and sockets U-11

and U-14 activate outputs 5-8.

Binary Outputs

A binary output on the SAT II controller is the electronic equivalent
of a relay contact which is used to complete a 24 VAC circuit to
activate on/off devices such as relays, 2-position valves, etc. The
binary output contacts cannot be used to complete a DC voltage
circuit; they will work with AC circuits only. The binary output
terminals are labeled H, COM, and C.

The SAT II controller is capable of providing 16 binary (on/
off) outputs. Each binary output requires 1 chip switch which is
purchased separately and is fi eld installed.

The terminals for the binary outputs are found at the lower left hand
corner of the SAT II controller. The “COM” to “H” contacts are
referred to as K1h-K8h. The “COM” to “C” contacts are referred
to as K1c-K8c.

Point Addresses

A Point Address uniquely identifi es a point within the ECC/WCC
II system. All point addresses have an associated “analog” or
“binary” value. The term “analog” simply means a value which
is represented by a number (such as room temperature, duct static
pressure, etc.). The term “binary” means the value is represented by
one of two conditions, ON or OFF. An input is a signal sent to the
ECC/WCC II system, and an output is sent from the ECC/WCC II
system. Therefore, room temperature is an analog input, fan status
is a binary input, and controlling a fan relay is a binary output.

In addition to the inputs and outputs that are wired to the SAT
II controllers, there are several software point addresses within
the system. For example, the ECC/WCC II system has 32 week
schedules. This means that a separate day/night schedule can be
assigned to 32 different areas of the building.

For example, assume that you have three different areas in a
building that have different schedules as shown in the following
table.

Area Occupied Time

Week Schedule #1 1st Floor West 8:00 am - 5:00 pm, M-F

Week Schedule #2 1st Floor East 7:00 am - 7:00 pm, M-F

Week Schedule #3 2nd Floor 9:00 am - 4:00 pm, M-Th

Week Schedule #1 is named W1, and the value of W1 will be On
between 8:00 am and 5:00 pm, Monday through Friday, etc.

The Name column in the table that follows is the name that you
should use when specifying a point address to the system. The “n”
is where a “point number” for the point address is to be entered.

Time & TimeB

These logical addresses are the actual time on HH:MM (TIME) and
minutes-since-midnight (TIMEB) formats. They are considered
analog values and have value ranges of 0000 to 2359 (TIME), and
0000 to 1439 (TIMEB).

Typical application of these logical addresses includes use in
the Dual Limit mode, allowing such modes of control as “On­Between-Times” and “Off-Between-Times.”

NEWSET, NEWMIN, NEWHR, NEWDAY, & NEWMON

These logical addresses are considered binary values and are based
on real-time. They have a pulse-type nature in that each of these
addresses has a value of one (or ON) for one second after the
occurrence of the specifi ed event. After the one second ON period
has elapsed, the value returns to zero (or OFF).

These addresses have several uses throughout the system. One
example would be the generation of a variable duty cycle output.
When used in conjunction with the separate “Minimum ON/OFF”
timers, these addresses can achieve cycles of from one second to
several days with a wide range of cycles.

Examples of “point addresses” within the system:

Data Registers

The ECC/WCC II system has some capabilities built into the
software that are very helpful, and you should be aware of them.
There is a Data Register associated with each of the Control
Output Screens. A Control Output Screen allows the user to tell
the satellite controller when to open and close the binary output
contacts. A Control Output Screen can be a Time Clock, EA Driver,
or Dual Limit Mode Screen.

Time Clock

When the binary output contact on the satellite controller is
controlled by a Time Clock Screen, the contact opens and closes
based on time only. For example, a Time Clock Screen can be used
to run a water circulating pump from 8:00 am to 5:00 pm, Monday
through Friday. Each Time Clock Screen has a Data Register
associated with it.

The Data Register is an analog value which is the time in seconds
since the satellite controller binary output contact closed. Assume
the water circulating pump is controlled by satellite controller
contact K1h. That is to say, the “COM” to “H” contact on channel
1 of the satellite controller closes to complete a 24 VAC signal to
run the pump.

Name Description

135A5 Satellite #135, Analog Input #5

A5 Analog Input #5, Current Satellite

W12 Week Schedule #12

S27 Optimal Start #27

C1 Setpoint Comparator on Analog Input #1

K1h

14P3

When K1h is ON, the chip switch within the
satellite controller which connects the electrical
path between the “H” and “COM” terminals on

channel 1 of the satellite controller is closed.

When K1h is OFF, the circuit is open.

Satellite #14, Analog Output #3.

The Data Register for a Time Clock Screen is named RnA or RnB.
R stands for data register, n refers to channel 1-8 of the satellite
controller, A means the “COM” to “H” contact, and B means the
“COM” to “C” contact. Therefore, the Data Register for contact
K1h is R1A. As contact K1h closes, the Data Register for contact
Klh (R1A) starts recording time in seconds. That is to say, the value
of R1A is the time in seconds since contact K1h closed.

RnA = Time in seconds since COM to H contact closed
RnB = Time in seconds since COM to C contact closed

The Data Register for a Time Clock Screen might be used to
start one piece of equipment after another has been started. For
example, assume we want to start an air handler two minutes after
the water circulating pump starts. The pump would be controlled
by a Time Clock Screen as mentioned above. The air handler would
be controlled using a Dual Limit Screen. The analog input value
for the Dual Limit Screen would be R1A, which is time in seconds
since the pump started. The Dual Limit Screen is set up to close the
contact for the air handler when the value of R1A is between 120
seconds and infi nity.

WCC II Operator’s Guide

Section 1: General Instructions

EA Driver

The EA Driver Mode is “3-point fl oating” control. For example,
assume that the control outputs on channel 2 of the satellite
controller are used to control a Tempmaster VAV box using the
EA Driver Mode. When the space needs heat, the “COM” to “H”
contacts on the satellite controller will close to drive the damper in
the VAV box to the closed position. When the space needs cooling,
the “COM” to “C” contact on the satellite controller will close to
open the damper in the VAV box.

There are two Data Registers associated with an EA Driver Screen.
The value of the fi rst Data Register is equal to the setpoint entered
on the EA Driver Screen and is referred to as “RnA.” The value
of the second Data Register is equal to the difference between the
setpoint and the actual temperature and is referred to as “RnB.”
“R” stands for data register, and “n” refers to channel 1-8 of the
satellite controller.

RnA = Setpoint
RnB = Difference between Setpoint and Measured Value (error)

For example, assume that the setpoint for the room in question
is 72 °F, and the actual temperature is 70 °F. The value of Data
Register R2A (setpoint) is 72 °F, and the value of Data Register
R2B (error) is -2 °F, since the actual space temperature is 2 °F
below the setpoint.

The Data Register could be used to turn on a second stage of heat
whenever the space temperature falls 2 °F below setpoint. Assume
that the second stage of heat is a heating coil which is energized
when satellite controller contact K3h is closed. A Dual Limit Screen
is used to control contact K3h. Data Register R2B is entered as
the analog input value for the Dual Limit Screen. When the value
of R2B is -2 or less (the space temperature is at least 2 °F below
setpoint), contact K3h closes to turn on the second stage of heat.

The Data Register for a Dual Limit Screen is named “RnA” or
RnB.” “R” stands for data register, “n” refers to channel 1-8 of the
satellite controller, “A” means the “COM” to “H” contact, and “C”
means the “COM” to “C” contact. Therefore, the Data Register for
contact Klh is R1A.

RnA = Difference between Setpoint and Measured Value (COM
to H)

RnB = Difference between Setpoint and Measured Value (COM
to C)

The Dual Limit Screen has two setpoints, the high limit and the low
limit. Since the Data Register is the difference between the setpoint
and the actual temperature, you have to “tell” the system what you
are considering the setpoint to be. Therefore, the Data Register is
measured from either the “Midpoint” or “Nearest Limit” of the
setpoints, depending on how the Dual Limit Screen is set up.

For example, assume that a Dual Limit Screen is used to control a
heat pump compressor to have the compressor off if the space is
between 70 and 74 °F. If the space temperature is below 70 °F, the
compressor will be on for heating, and if the space temperature is
above 74 °F, the compressor will be on for cooling. Assume the
actual space temperature is 76 °F.

The Data Register can be measured from either the “Midpoint”
or the “Nearest Limit.” If the Data Register is measured from the
“Midpoint,” the value of the Data is 4 °F.

Low Limit High Limit
70 72 74 76
4 Deg
Midpoint Actual Temperature

Data Register

Dual Limit

When the binary output contact on the satellite controller
is controlled by a Dual Limit Screen, the contact opens and
closes based on how the analog input value compares to a pair
of setpoints. There is one Data Register for each contact on the
satellite controller which is controlled by a Dual Limit Screen. The
value of the Data Register is the difference between the setpoint
and the actual temperature.

Operator Interfaces

Difference between actual temperature and the “Midpoint” of the
setpoints = 4 °F, and therefore, the value of the Data Register is 4
°F.

If the Data Register is measured from the nearest limit, the value of
the Data Register is 2 °F.

Alarm Print-Out and Call-Out

The ECC/WCC II will automatically print alarms as they occur
on a local printer or will call out over standard telephone lines
and report the alarms to a remote printer. There are eight different

Analog Alarm Limit

Each analog input can have a low and high limit assigned to it
on the Analog Input Screen. If the value of the analog input falls
below the low limit or rises above the high limit, the system
automatically generates an alarm. For example, assume that the
analog input in question is a room temperature sensor located in
an offi ce space. If the space temperature falls below 68 °F or rises
above 80 °F during the occupied period, we want an alarm to print
on the printer. To set up the alarm limits, fi rst sign on by accessing
the System Parameter Screen and entering your password. An
access level of 1 or greater is required to enter or change alarm
limits. After you are signed on, return to the Main Menu and place
the cursor over “ANALOG INPUT” and press <RETURN>. An
Analog Input Screen similar to what is shown below should come

The alarm limits along with the alarm type and alarm message
numbers are assigned on this screen (see the Analog Input Screen
section of this guide on page 3-9 for more information). If the
space temperature drifts out of the entered alarm limits, the system
will automatically generate an alarm. For example, assume that the
space temperature rises above the high limit value of 80 °F. Alarm
message #1 (High Temperature) along with the time and date of the
alarm and the high peak value of the room temperature will appear
on Analog Input Summary Screen and the Alarm Summary Screen.
Within one minute from the time the alarm appears on the screen, it
will automatically be printed on the local printer. (To acknowledge

Satellite Fail Alarm

If the Central Processing Unit loses communications with a satellite
controller, a Satellite Alarm will print on the printer showing which
satellite is out of service and the time and date of the alarm.

Operator Sign On/Off

The ECC/WCC II system will automatically print the operator ID,
time, and date when an operator signs on or off the system. The
message will also indicate the password level of the operator and
if he or she signed on/off locally or remotely. When the operator
signs off, the total amount of time the operator has been signed on
the system will also be printed.

Manual Overrides

When the operator uses the Override Screen to force a point to
another value, a message will be printed indicating what was
overridden along with the time and date of the override.

To utilize the “call-out” on alarm feature, a 1200 baud Hayes
compatible modem is required at the on-site ECC/WCC II
computer, and a 1200 baud Hayes compatible modem and an IBM
graphics compatible printer, custom confi gured with a high speed
serial adapter is required at the remote site.

System Re-Boot

When the system is re-booted or restarted by either shutting the
computer off and then turning it back on or using <Ctrl> <Alt>
and <Del>, a message is shown on the printer showing the time
and date of the re-boot.

Hardware Requirements

The ECC/WCC II print routine is a standard software feature, and
the standard CPU has all of the hardware items required to support
a local printer. If local print-out is desired, an Okidata 182A, IBM
compatible, parallel printer with a standard IBM compatible cable
is recommended. We cannot offer trouble-shooting support if other
printers are used.

The local printer must be a parallel printer as opposed to a serial
printer. The ECC/WCC II CPU has a parallel and a serial port for
data output. The difference between a parallel and serial port is the
way in which data is transmitted. The only purpose a parallel port
serves is to send data to a printer on-site, and therefore the local
printer must be a parallel printer.

__________________________________________

The programs and data which are necessary to cause the personal
computer to act as the ECC/WCC II Central Processing Unit
are saved on a diskette(s) similar to the way music is stored on a
cassette tape.

Note: The personal computer also has special integrated

circuit boards, manufactured at WattMaster, which allow it to

act as the CPU.

After the satellite controllers have been installed and powered up,
the Central Processing Unit (personal computer) set up, and the 2­wire communication line between the satellite controllers and the
CPU hooked up (see the Installation and Trouble Shooting Guide
for satellite controller start-up and check-out information), the
software needs to be loaded into the system. Loading the software
is a term which means that data on the diskettes is transferred into
the memory of the personal computer and/or into the memory of
the satellite controllers.

The personal computer used with the ECC/WCC II system may
have either two fl oppy disk drives or one fl oppy disk drive and one
hard disk drive. If the front end computer is an IBM system 2, the
fl oppy disks are 3.5 inch; otherwise, they are 5.25 inch disks. The

3.5 inch disks are sometimes referred to as micro fl oppy disks or
micros. The disk drive on the left hand side of the computer (Drive
A) always accepts a fl oppy disk. The right hand disk drive uses
either a fl oppy disk or a hard disk. If it is a fl oppy disk, then it is
referred to as drive B; if it is a hard disk then it is referred to as drive
C. Hard disks hold much more data than a fl oppy. A hard disk is
recommended on systems which have over 20 satellite controllers
and is required on systems which utilize Enhanced Color Graphics
or the Telephone Override Feature.

You should receive the following disks with an ECC/WCC II
system:

Dual Floppy Systems

“DOS Disk - Version 3.3”
“Drive A Operating Disk”
“Drive B Operating Disk”
“Drive A Back Up Disk”
“Drive B Back Up Disk”

Hard Disk Drive Systems

“DOS Disk - Version 3.3”
“Back Up Disk #1”
“Back Up Disk #2”

The DOS (Disk Operating System) Manual is shipped in the box
with the ECC/WCC II CPU (personal computer). You should
fi nd two disks in the back of the DOS manual; you need the disk
labeled “DOS”. The ECC/WCC II system will operate with DOS

2.1 or greater.

CAUTION: DOS 2.1 must be used on dual fl oppy systems

which have 5.25 inch disk drives. The DOS 3.3 fi le is too large

and will not allow enough room for the other ECC/WCC II

fi les.

If you have a dual disk system, “Disk A” will stay in Drive A of the
ECC/WCC II CPU (personal computer) and “Disk B” will remain
in drive B. If you have a “Hard Disk” system, the “Disk A” and
“Disk B” will be copies onto the hard disk (Drive C).

It is very important to make back-up copies of the disks after the
system has been “programmed” to control your building.

You can tell if your system has a hard disk by looking at the disk
drives on the personal computer. A disk drive that uses a fl oppy
disk has a door with a slot which allows you to insert and remove
the disk. The hard disk is permanently in the drive, and therefore
there is no door on the front of the drive. If your system has two
fl oppy disk drives, then it is referred to as a “ Dual Floppy” or a
“ Dual Disk Drive” system. If the disk on the right does not have a
disk drive door, then the disk in the right hand drive is a hard disk,
and the system is referred to as a “Hard Disk” or “Fixed Disk”
system.

Operator Interfaces

Dual Disk Drive Systems

If the ECC/WCC II CPU (personal computer) has two “fl oppy”
disk drives, then the following procedure should be followed to
load the software into the computer. Before you can load the ECC/
WCC II software, you need to have the following items:

1) “Drive A Operating Disk”

2) “Drive B Operating Disk”

2-1

WCC II Operator’s Guide

Section 2: Initiating the System

Insert the ECC/WCC II “Drive A Operating Disk” into drive A
(left hand drive), the “Drive B Operating Disk” into drive B (right
hand drive) and “boot-up” the system.

If your computer is off: Turn the power on. Then close the
disk drive doors.

If your computer is on: Press and hold <Ctrl> and <Alt>.
Then press and hold <Del>.

After a few seconds the computer should read the data from the
disks, and it will automatically bring up the ECC/WCC II Main

Menu.

Note: As you program a system to control a building,

information is written on the disks. It is very important to

make back-up copies of the “Working” disks after the system

has been programmed to control the building.

Hard Disk Drive Systems

If the ECC/WCC II CPU (personal computer) is a “Hard-Disk”
system, the ECC/WCC II program is stored on the hard disk so
“booting-up” the system will cause the ECC/WCC II Main Menu
to appear on the screen.

If your computer is off: Open the drive A door and then turn
the power on.

If your computer is on: Press and hold <Ctrl> and <Alt>.
Then press and hold <Del>.

After a few seconds the computer should read the date from the
hard disk (drive C) and the ECC/WCC II Main Menu system
should eventually appear on the screen.

The hard disk can hold a vast amount of data which can accidentally
be erased or lost due to system malfunction, operator error, etc.
Therefore it is extremely important to make a back-up copy of
the data on the hard disk. As you program a system to control a
building, information is written on the disks. Therefore, back-up
copies of the hard disk should be made after the system has been
programmed to control the building.

Copying Disks

“ Backing-up” a disk means to make a copy of the disk’s data on
another disk. Back-up copies of all of the disks should be made in
case the primary disk is destroyed, lost or stolen. The information
on a hard disk can be transferred to several fl oppy disks, a cassette
tape or another hard disk.

To make a back-up copy of a disk, you must have the following
items:

1 - The “Source Disk” (the disk you want to back up)

2 - The “Target Disk” (the disk that will receive the data)

3 - DOS (version 2.1 or higher)

Formatting Disks

The fi rst step in copying disks is to format the disk which will serve
as the “Target Disk.” After the disk has been formatted, the system
can direct the fi les to be stored in certain places.

The following procedure should be followed to format disks:

WARNING: Make sure that the disk that you format does not

contain any programs that you want to save. The formatting

process will erase everything presently on the disk.

Before you start the disk formatting procedure, the “A>“ should
appear on the screen. If you are using the ECC/WCC II system
to format the disks, you should “exit” from the ECC/WCC II
system.

To exit from the ECC/WCC II program, you must have level 3
access. Access the Utility Screen and then move the cursor down
to “WCC/SCC File Management” and then press the right arrow
key. The cursor should move to “Exit WCC II System.” Then press

<Enter>. The system should exit to DOS and either an A>, B> or

C> will appear on the screen. If the B> or C> appears, the A> will
appear if you enter the following command:

B>A: <Enter>

The diskette in drive B now contains the same data as the disk in

We recommend using the newly made disk in the system and
keeping the original in a safe place to be used as back-up in case
of an emergency.

Copying Data - Hard Disk Drive
Systems

The data that is stored on the hard disk can be accidentally erased
or the hard disk can malfunction resulting in all the data being
destroyed. Since a hard disk can hold such a huge amount of data,
it is extremely important to have a back-up copy of the information
on the hard disk.

There are several ways to obtain a back-up copy of the hard disk,
which include:

Floppy Disk Back-Up

Cassette Tape Back-Up

Selected Program Back-Up

Copying Data - Dual Floppy Systems

The information from the “Source Disk” is copied onto the “Target
Disk” using the following procedure:

1) Insert the “Source Disk” into drive A (left drive) and

1.
close the door. Insert a newly formatted diskette into
drive B and close the door. With the A> prompt showing
on the screen, type the following command:

A>COPY *.* B:/V <Enter>

The screen will now display the copy process:

A>COPY *.* B:<Enter>

COMMAND.COM

2-4

The information from the hard disk can be copied onto fl oppy disks
using the disk copy procedure outlined in the DOS manual. The
problem with this method is that it is very time consuming and it
requires many fl oppy disks. Therefore, we recommend using either
a cassette tape or a selected program to back up the data on the hard
disk. If you need help in selecting a tape or selected program for
your system, feel free to contact WattMaster for assistance.

If your system has a 5.25 inch fl oppy drive, it will take several
disks to back up the hard disk, and therefore, a back-up program
should be used. If your system has a 3.5 inch fl oppy drive, you can
generally copy all of the system fi les and help fi les onto one disk,
all of the data fi les onto another disk, and the custom screen fi les
onto a third disk. If the color graphics option is used, a back-up
program is recommended.

WCC II Operator’s Guide

Section 2: Initiating the System

Generally, the ECC/WCC II systems with less than 20 satellite

Returning to the ECC/WCC II Program

Dual Disk Drive Systems

If you are using the ECC/WCC II personal computer to copy the
disks, the need to replace the ECC/WCC II disks in the proper
drives and “re-boot” the system by fi rst pressing <Ctrl> and <Alt>,
and then pressing <Del>. After a couple of minutes, the Main Menu
should appear on the screen.

Assign Operator Access Codes

Access codes can be assigned for up to 16 operators with 4 levels
of access. The systems are sent from the factory with an operator
number of 33333 and an access number of 3333. To assign other
codes, follow the steps in this section.

STEP #1: With the Main Menu showing on the screen, place

the cursor above “System Parameters” and press <Enter> to
access the System Parameter Screen. The System Parameter
Screen should come into view with the computer awaiting the
operator ID.

STEP #2: Input the factory set identifi cation number of

33333 and press <Enter>. The numbers at the top of the

keyboard must be used. The cursor will automatically move to
the right and await the code ID.

STEP #3: Input the factory set code number of 3333 and

press <Enter>. The message to the right of the cursor should
change from “View Screen Only” to “View All

.”

Codes

STEP #4: Use the right arrow key to move the cursor to the

right of the “View All Codes” message.

STEP #5: Press <Enter>, and the screen will appear which

will allow codes for 16 operators with 4 levels of access. The
descriptions of the access levels are listed at the bottom of this
screen.

Hard Disk Drive Systems

Open the door on drive A and “re-boot” the system by pressing

<Ctrl> and <Alt> and then pressing <Del>. After a couple of

minutes, the Main Menu should appear on the screen.

CAUTION: The CPU will not communicate with the satellite

controllers while it is going through the “re-boot” process. If

the satellite controllers do not communicate with the CPU for

approximately two minutes, they will go into local set. The

time it takes for the system to “re-boot” will usually cause the

satellite controllers to go into local set.

STEP #6: Access codes can be assigned for the operators

who will be using the system. The operator ID is 5 characters
using any letters, numbers, or symbols (it is important to
input all 5 characters when inputting an operator code; a
space may be entered as a character if desired). The code ID
is 4 characters using any letters, numbers, or symbols (it is
important to enter all 4 characters for the code ID; a space may
be used as a character if desired). The system will distinguish
between small and capital letters. To assign an operator ID,
type the desired characters and press <Enter>. The cursor will
automatically move to the right and await the code ID. Type
the desired code ID and press <Enter>. The cursor will now
automatically move to the right and await the Level access
number. Type in this Level number (1 through 3, 1 being the
lowest and 3 being the highest) and press <Enter>.

STEP #7: After the codes have been entered, make sure

you know what the codes are before leaving this screen. We
recommend leaving the 33333, 3333 access code until the
other codes are tested. To leave this screen, press <HOME>
twice to return to the System Parameter Screen. Press

<HOME> once more to return to the Main Menu.

any spaces which were entered using the space bar.

Password Entry

To be able to make any changes to the inputs in the system, you
must have a password which has either a level 1, level 2 or level
3 access assigned to it. You enter your password by following the
steps in this section.

STEP #1: With the Main Menu showing on the screen, place

the cursor above “System Parameters” and press <Enter> to
access the System Parameter Screen. The System Parameter
Screen should come into view with the computer awaiting the
operator ID.

WCC II Operator’s Guide

Section 2: Initiating the System

STEP #2: Input your assigned operator code and press

<Enter>. The cursor will automatically move to the right and

await the code ID.

STEP #3: Input your assigned code ID and press <Enter>.

You are now “signed on” and may enter and/or change data as
necessary.

Note: You must enter your exact password. The system

distinguishes between upper and lower case letters, and it

recognizes spaces which are created using the <space bar>.

<Ctrl><A>: Acknowledge Alarms

When an alarm occurs within the system, the alarm condition
appears on its respective summary screen as a fl ashing display
generally on the right side of the display. Once the alarm has been
acknowledged, one of two possible conditions will be displayed.

The fi rst condition is when an alarm is acknowledged, but the
alarm remains outside of the alarm limits. When this happens, the
alarm information is still displayed on the screen, but it appears
solid instead of blinking. The second condition is when an alarm
is acknowledged AND the alarm is inside the alarm limits. In this
instance, all alarm information for that point is cleared (or removed)
from the screen.

To acknowledge new (blinking) alarms, position the cursor (>)
at the point for which you wish to acknowledge alarms. Once
positioned, press and hold <Ctrl>, then press <A>, and then release
both keys at the same time. At this point you should notice that one
of the above stated conditions is occurring.

<Ctrl><G>: Display Graphs

The ECC/WCC II system has graphs for the Analog Trend Screen,
the Proportional Reset Screen, and the Look-Up Table Screen that
can be displayed on the screen and can be printed on the printer
using the manual “Print Screen” command.

The graph for the Analog Trend - Trend Logging Screen is accessed
while the cursor is at the “Home” position of an Analog Trend
Screen. Press and hold <Ctrl>, then press <G>, and then release
both keys at the same time. Press any key to return to the Analog
Trend Screen.

Note: If the ECC/WCC II system is “re-painting” the screen

at the moment you access the graph, the full graph will not be

displayed. To make sure you get a full graph, move the cursor

to the “HOME” position on the screen, and press <Ctrl><G>

while the cursor is blinking at the HOME position.

The Proportional Reset Screen also has a graph associated with
it that can be accessed by pressing <Ctrl><G> while the cursor is
anywhere on the Proportional Reset Screen.

The graph for the Look-Up Tables (GA 121-128) is accessed in the
same way. While the cursor is at any position on a Global Analog

Look-Up Table, simultaneously press <Ctrl><G> to cause the
Look-Up Table graph to be displayed on the screen.

<Ctrl><K>: Clear Communication Errors

The ECC/WCC II system keeps track of the transmission and
receive errors between the Central Processing Unit (personal
computer) and the satellite controllers on the Satellite Summary
Screen. The <Ctrl><K> feature clears the existing number of errors
and is used for trouble-shooting purposes.

<Ctrl><R>: Reset Trend Logs or Global Analog
Accumulation Screens

When you are at a Trend Logging Screen and wish to reset (clear)
the existing trend log data on the particular screen, simply press

<Ctrl> and <R> at the same time. This should automatically reset

(clear) the data on the Trend Log Screen. On new systems, the Trend
Log Screens should be reset before they have been programmed to

clear out any “bad data” that might be in the satellite controller.

The <Ctrl><R> feature is also used to reset the global analogs
using the integral mode and the Energy Consumption Screen.

If the system is trying to call-out an alarm and it cannot report
its information to the remote printer for some reason, the system
will continue to try and call the telephone number(s) forever unless
you press <Ctrl> and <R> simultaneously while the cursor is
at the “Disabled by” position for that alarm type on the System
Parameters Screen.

<Ctrl><S>: Hold Screen

The Analog Input Summary Screen automatically displays alarm
messages as the alarm occurs. There are four different messages
that show on the screen (i.e. the time, date, user entered alarm
message, etc.). After the fi rst message for a given alarm is displayed
for several seconds, the next message will appear. The <Ctrl><S>
feature will cause the screen to hold the same message to give you
time to read it before the next message appears.

To use the <Ctrl><S> feature, place the cursor on the “HOME”
position of the Analog Input Summary Screen. Press and hold

<Ctrl> and then press <S>, holding both keys down for an instant

and then releasing both keys at the same time.

WCC II Operator’s Guide

Section 3: Screen Descriptions

<Ctrl><Home>: Clear Input Data from Present Screen

You must have a password level of 3 to use the <Ctrl><Home>
feature.

Each screen (or point) has data which is saved in the memory of the
CPU or the satellite controller. Before any processing of the data
entered on a screen is performed, the system checks the point’s
“structure valid” indicator to insure that the data it contains is valid
and properly formed. If the point is not valid, then that point is
skipped and processing continues with the next point. In addition,
all summary data is removed from that point’s summary screen.

To clear a screen (invalidate it), the cursor must be in the “Home”
position on the individual screen that is to be cleared. Once there,
press <Ctrl><Home> at the same time. The data on the screen
should be cleared away. Once you have cleared a point, the data
for that point is lost and it cannot be recovered. Therefore, make
sure you have the right point before using <Ctrl><Home>.

<Ctrl><PgUp>: Return to the “Sat #” position on the
Main Menu

You can automatically go to the “Sat #” position on the Main Menu
from nearly anywhere in the system by using the <Ctrl><PgUp>
command.

<Alt><A>: Clear All Satellite Alarms, Used in Alarm
Summary Screen

If you want to clear all of the satellite alarms in the system at one
time, access the Alarm Summary Screen. Once there, press
and <A> simultaneously and all of the non-active alarms will be
cleared.

Group 3 Help Keys

The ECC/WCC II Special Keys program allows you to “teach” the
system a set of key strokes that can be repeated at set time intervals
at a specifi c time each day when a global binary value goes ON or
manually. Among other things, this allows you to automatically
print screens on the printer at certain times or when certain events
occur without operator interface. There are 10 auto-scan/print
routines in the ECC/WCC II system. Each of the 10 routines can
have up to 100 key strokes.

To “teach” the system a set of key strokes, follow this procedure: i

1) Start the “learning” process at the “Sat #” position on the main
menu by pressing <Alt> and then <L>, holding both keys down
at the same time for an instant and then releasing both keys at the
same time.

within the ECC/WCC II system, fi rst go to the screen that you want
to copy and simultaneously press <Alt> and <F>. Then go to the
screen which is to receive the data and simultaneously press <Alt>
and <C> and the data will automatically be entered in the screen.
See section titled “Copying Information Within the Same Satellite”
in this guide for additional information.

<Alt><F>: Copy Data from Present Screen

If you want to copy the data from one screen to another screen
within the ECC/WCC II system, go to the screen that you want
to copy and simultaneously press <Alt> and <F>. Then go to the
screen which is to receive the data and simultaneously press <Alt>
and <C> and the data will automatically be entered in the screen.
See section titled “Copying Information Within the Same Satellite
in this manual for additional information.

While you are in the “learning” mode, the following keys perform
special functions (to use these special keys, press <Alt> fi rst and
then press the second key, holding both keys down for an instant
then releasing both keys):

<Alt><A>: Enter append mode; Used at “Sat #”
position on Main Menu Screen

The append mode is used to add key strokes to an existing autoscan/
print routine. The <Alt><A> feature works only when the cursor is
at the “Sat #” position on the Main Menu Screen.

<Alt><E>: Stop learning or append mode

After you have entered all of the key strokes that you would like to
“teach” the system, use <Alt><E> to exit from the learning mode.

<Alt><N>: Generate a form feed in the replay mode

If you are programming the system to automatically print a screen
(or screens) on the printer during the replay mode, the <Alt><N>
command causes the printer to generate a form feed to cause the
outputs to be printed on separate pages.

The Main Menu Screen allows you to view the available screens
within the ECC/WCC II system. To get to a screen listed on the
Main Menu, use the arrow keys to position the cursor over the
name of the screen you want to access and press <Return>.

The Main Menu is divided into three categories: Sat #, Overview,
and Central Unit.

Sat #____

The information associated with the screens within this category
is stored in the satellite controllers and IS NOT stored in the CPU
(personal computer). It is a very good idea to save this information
on a back-up disk by using the Satellite Save/Restore program
located in the overview category.

Overview

This section allows the operator to perform operations and view
screens which affect all of the satellite controllers on the system.
The information associated with the screens located in this
category is stored in the CPU (personal computer). When the

screens in this category are programmed for the fi rst time, or when
a change is made to these screens, the system automatically stores
the information on the data disk.

Central Unit

The screens located in this category are GLOBAL commands.
Global commands “travel” along the two-wire communication
loop and are used by any or all of the satellite controllers. All of
the satellites are constantly monitoring this information but only
certain satellites will react to the information depending on how
they have been programmed. The information associated with
the screens located in this category is stored in the CPU (personal
computer). When the screens in this category are programmed for
the fi rst time or when a change is made to these screens, the system
automatically stores the information on the data disk.

The version number of the software presently being used by the
ECC/WCC II system will appear at these locations. Backtask is a
portion of the ECC/WCC II software. Each version of the WCC2
software operates with a specifi c version of Backtask. This has
been added to insure that the right version of Backtask is operating
with the WCC2 software.

* These versions of software require the front end computer to
have 448K of RAM memory; later versions require 640K.

An analog input is a signal sent to the satellite controller that can
be represented by a number such as temperature, pressure, etc. The
Analog Input Screen is used to “tell” the ECC/WCC II system the
characteristics of the sensor and to set alarm limits. The “Binary
Setpoint” option at the bottom of the Analog Input Screen can be
used to convert the analog input to a binary (On/Off) input.

Analog Inputs

Specifi es the summary type to be displayed. Because this is a
“choice” fi eld, the list of available choices will be displayed at the
bottom of the screen:

CHOICES: <Anal, Cont, Anal, Trend, Logi, TUC>

You can access one of the screens which appear in this choice fi eld
without returning to the Main Menu by pressing the <space bar>
until the desired summary type has been selected and then pressing

<Enter>.

Satellite______

Specifi es the number of the satellite which you are currently
communicating with. If you would like to view the analog input
summary data for a different satellite, use the arrow keys to move
the cursor to this fi eld, enter the desired satellite number, and press

<Enter>.

To view or edit a specifi c analog input, use the arrow keys to move
the cursor (shown as “>” along the left-hand side of the screen) to
the desired point and press <Enter>. The Analog Input Screen for
the specifi ed point will now appear.

Current Value

The current value of the analog input is automatically displayed
here.

Alarm Limits

The alarm limits which were input on the Analog Input Screens
will automatically be displayed here.

Stat

The present “ON” or “OFF” status of the binary input which is
controlling the schedule for the alarm limits is shown here. For
example, if week schedule #1 (W1) has been input to control
the schedule of the alarm limits, the message “ON” will appear
here when week schedule #1 is “ON” and “OFF” will appear
when week schedule #1 is “OFF”. When W1 is “ON” the “On
Schedule” alarm limits will be active, and when W1 if “OFF” the
Off Schedule” alarm limits will be active.

Mode

The “alt” message will appear here when the alternate alarm limits
are active. When the input value which has been entered on the
Analog Input Screen to select the alternate alarm limits is “ON,”
the ECC/WCC II system will use the “Alternate Alarm Limits”
and the “alt” message will be displayed here.

IBM COLOR SCREENS OR PS2 SYSTEMS

When an alarm occurs, the alarm message will show on the screen
using the background and foreground colors chosen for alarms in
the Set Monitor Color Screen. To acknowledge an alarm, position
the cursor (shown as “>” along the left hand side of the screen)
at the point for which you wish to acknowledge the alarm. Then
press <Ctrl><A>, holding both keys down at the same time for
an instant and then releasing both keys. At this point, one of two
things should happen. If the value of the analog input is presently
within the alarm limits, the message will disappear. If the value of
the analog input is not within the alarm limits, the message will stay
on the screen, but it will show on the screen using the background
and foreground colors chosen for the cursor display.

Alarm Details

This location will automatically display the alarm message, the
high or low value of the analog input, and the time and date of the
occurrence of the peak value.

IBM PC SYSTEMS WITH A MONOCHROME (GREEN)

Satellite # _______

Specifi es the number of the satellite which you are currently
editing. If you would like to edit a different satellite, use the arrow
keys to move the cursor to this fi eld, type in the desired satellite
number, and press <Enter>.

Analog Input # ________

This “fi eld” actually contains two separate fi elds. The fi rst fi eld
specifi es the point “type” (i.e., analog input, control output, analog
output, etc.) and displays the current type in textual form. Because
this is a “choice” fi eld, the list of available choices will be displayed
at the bottom of the screen:

Additionally, this fi eld specifi es the point number to edit. For the
Analog Input Screen, this number can range from one to eight,
corresponding from A1 to A8, respectively. If you would like to
edit a different point, move the cursor to this fi eld by using the
arrow keys, enter the desired point number, and press <Enter>.

Description:

A short message is entered here which is displayed on Summary
Screens to help you remember points within the system. You may

enter up to ten characters (control codes, ALT codes, and the double
quote character are not allowed).

Type:

CHOICES: <Anal, Cont, Anal, Trend, Logi, TUC>

You may make your selection by pressing the <space bar> until
the desired choice appears and then pressing <Enter>. (If you select
a point type that is different than that currently being displayed, the
screen will be rewritten with the appropriate screen and data.)

Operator Interfaces

This fi eld is automatically fi lled in by the system. On screens 2-8,
this will always read “ANALOG.” On screen number 1, it will
read either “ANALOG” or “PULSE” depending on the position of
the pulse switch on the satellite controller.

3-9

WCC II Operator’s Guide

Section 3: Screen Descriptions

Pattern for Values Associated With This Input:

Specifi es where you would like the decimal point to appear in the
value displayed by the system. Because this is a “choice” fi eld,
a list of available choices will be displayed at the bottom of the
screen:

CHOICES: < x,xxx , xxx.x , xx.xx , x.xxx >

You may make your selection by pressing the <space bar>
until the desired data pattern has been selected and then pressing

<Enter>.

Units @ 0% scale:
@ Full scale:

If the screen type is “ANALOG,” this specifi es the scaling
information used by the system to proportionally scale the input
value to the desired range. The raw input value to the satellite
controller ranges from zero to one volt. If the scaling information
has been set to 0 at 0% scale, and 100 at Full scale, a raw input
value of 0.6 volts would produce a scaled value of 60.

_______ Pulses = _______ Hours

If the screen type is “PULSE,” this specifi es the calibration
information for the pulse meter connected to channel 1 of the
satellite controller. The fi rst input is a “choice” fi eld, and therefore
a list of available choices will be displayed at the bottom of the
screen.

CHOICES: < 100, 1000 >

The second input is used to “scale” or “calibrate” the particular
sensor that is being used. For example, consider a pulse meter
which measures the kwh of a building. Electrical meters are
basically a small motor whose speed is proportional to power
being used. Let’s consider a meter where one revolution equals
one kwh, and the meter sends 5 pulses to the satellite controller
for every 6 revolutions. Therefore, we would enter “100 Pulses =
120 kwh Hours.” (Note: maximum pulse rate allowed = 4 pulses
per second.)

5 pulses = 6 revolutions
1 revolution = 1 kwh
5 pulses = 6 kwh
100 pulses = 120 kwh

Units-of Measure Message #: 1

A number is entered here that references a message on the On/Off
Units Messages Screen. For example, if units-of-measure message

#4 is “° F,” entering “4” will cause “°F” to be displayed as the
units-of-measure for the analog input.

Filter Time Constant: ____ Seconds

Specifi es the sampling rate of the analog input. This is used by the
satellites to “fi lter” (or smooth) the analog input signal. This can be
used on inputs that “jump around” to reduce sporadic load control.
Because this is a “choice” fi eld, the list of available choices will be
displayed at the bottom of the screen:

CHOICES: < 0, 1, 2, 4, 8, 16, 32, 64 >

You may make your selection by pressing the <space bar> until
the desired fi lter time constant has been selected and then pressing

<Enter>.

------ALARMS------

Controlled by:

Specifi es the binary value that selects the ON or OFF alarm limits.
When this value is OFF, the OFF alarm limits are selected; when it
is ON, the ON alarm limits are selected.

Alarm Type:

Specifi es the priority (or “importance”) level for any alarms
generated by this input. Alarm types range from one (highest
priority) to eight (lowest priority). The system prints out and calls
out higher priority alarms fi rst. (The fi rst fi ve alarm priorities (1-5)
have call-out-on-alarm capabilities.)

Alarm Message # Low: ___ High: ___

Specifi es a pair of message numbers, one for LOW alarms and
the second for any HIGH alarms. These numbers are used by
the system to reference a message which is entered on the Alarm
Message Screen.

3-10

Operator Interfaces

WCC II Operator’s Guide

Section 3: Screen Descriptions

Alternate Limits Selected By:

Specifi es the point that initiates the Alternate mode. When this
address is zero (or OFF), the Normal alarm limits are selected;
when it is one (or ON), the Alternate alarm limits are selected.

Limits Low High
On _____ _____ °. F
Off _____ _____ °. F
On (alt) _____ _____ °. F
Off (alt) _____ _____ °. F
Local Set _____ _____ °. F

This group of inputs specifi es the alarm limits for the “Normal,”
“Alternate,” and “Local Set” modes. Each mode has a LOW and
HIGH limit. When the value of the analog input goes out of these
limits, an alarm is generated, and it will automatically print-out and
call-out (provided that the print-out has not been disabled on the
System Parameters II Screen and the call-out has not been disabled
on the System Parameters Screen).

There are two fi elds on this screen that determine which set of
limits are active—the status of the “Controlled by” fi eld and the
status of the “Alternate Limits selected by” fi eld. When the value
that has been input in the “Controlled by” fi eld is ON, either the
“On” limits or the “On (Alt)” limits are active depending on the
status of the value input in the “Alternate Limits selected by” fi eld.
If the value in the “Alternate” fi eld is on, the “On (Alt)” limits are
used, and when the “Alternate” value is OFF, the “On” limits are
used.

------ BINARY SETPOINTS ------

____Above:____
____Below:____

These inputs are used to convert the analog signal to a binary (On/
Off) signal. The value that is going ON and OFF is a software point
referred to as a comparator. Each analog input has a comparator
associated with it named “Cn.” The comparator for analog input #1
is “C1,” analog input number 2 is “C2,” and so on. The status of the
comparator can be seen on the Analog Input Summary Screen.

When the User

has selected:

OFF Above &
OFF Below:

OFF Above &
ON Below:

ON Above &
OFF Below:

ON Above &
ON Below:

Because this is a “choice” fi eld, a list of available choices will be
displayed at the bottom of the screen:

The value of the comparator is:

OFF when the Analog Input value is greater than
the ABOVE setpoint or less than the BELOW
setpoint, and ON when the Analog Input value is
equal to either one or between the two setpoints.

OFF when the Analog Input value is greater
than or equal to the ABOVE setpoint or until the
Analog Input value becomes less than the BELOW
setpoint, and ON when the Analog Input value
is less than or equal to BELOW setpoint or until
the Analog Input value becomes greater than the
ABOVE setpoint.

OFF when the Analog Input value is less than or
equal to the BELOW setpoint or until the Analog
Input value becomes greater than the ABOVE
setpoint, and ON when the Analog Input value is
greater than or equal to the ABOVE setpoint or
until the Analog Input value becomes less than the
BELOW setpoint.

OFF when the Analog input value is equal to either
one or between the two setpoints, and ON when
the Analog Input value is greater than the ABOVE
setpoint or less than the BELOW setpoint.

The local set alarm limits become active if the front end
computer quits communicating with the satellite controller. After
communications are re-established, any alarms that occurred while
the satellite was in local set will be reported.

WCC II Operator’s Guide

Section 3: Screen Descriptions

On Message #:
Off Message #:

Specifi es a pair of message numbers, the fi rst for the ON state and
the second for the OFF state of the comparator. These numbers
are used by the system to reference a message on the ON/OFF
Units Message Screen. For example, the comparator might be set
up to come on when the outside air temperature is below 55 °F for
economizer operation. Set up the On/Off Message Screen so that
message #3 is “ECON” and message #4 is “REFRIG.” The “On
Message” number would be “3” (ECON), and the “OFF Message”
number would be “4” (REFRIG).

CONTROL OUTPUT SCREENS

The Control Output Screens are used to “tell” the satellite controller
when to open or close the binary output contacts. A binary output
contact may be “programmed” using one of the following
screens:

1) EA Driver

2) Dual Limit

3) Timeclock

EA Driver Screen

The EA Driver Screen is generally used to control the electric
actuators on a Tempmaster variable air volume (VAV) box;
however, it can be used for other applications. The Tempmaster
“EA Actuators” have two 24 VAC motors—one motor drives
the damper closed, and the other motor drives the damper open.
The EA Driver Screen uses two binary outputs on the satellite
controller—the “COM to H” contact closes on a call for heating,
and the “COM to C” contact closes on a call for cooling. The
generic term for the method of control provided by the EA Driver
Screen is “3 point fl oating control.” When the analog input signal is
within the deadband, both contacts open and the actuator does not
move. When the analog input signal falls below the setpoint into
the pulse band, the “COM to H” output contact pulses at a preset
rate to slowly move the actuator toward the required position. If
the analog input signal falls below the pulse band, the “COM to H”
contact closes and the actuator drives full speed. When the analog
input signal rises above the setpoint, the same sequence occurs
with the “COM to C” contact.

3-12

Dual Limit Screen

The Dual Limit Screen is used to “program” one binary output on
the satellite controller to open and close based on how the value
of an analog input compares to the setpoints. It is called dual limit
because you have the option of entering two setpoints if required.
For example, if you are using the SAT II to control a heat pump
compressor, the binary output should close if the space temperature
is below 72 °F for heating, close if the space temperature is above
76 °F for cooling, and be open when the space temperature is
between 72 °F and 76 °F.

Timeclock Screen

The Timeclock Screen is used to open and close a binary output
based on time only. For example, if you want the SAT II to run
a pump from 8:00 am to 6:00 pm, Monday through Friday, a
Timeclock Screen would be used to “program” the binary output
for the pump.

STATUS

A message is displayed here to help you monitor the status of the
equipment being controlled. For items being controlled by the time
clock or dual limit modes, the on/off messages which were input
on the respective control output screens will automatically appear
here. For the EA driver mode you will see one of the following
symbols or messages:

idle: When this message appears, the value of the analog input

associated with the control output is within the setpoint
deadband. In the idle mode, both the “h” and “c” contacts
are open and the controlled device remains in its present
position.

->C When this symbol appears, the value of the analog input
associated with the control output is above the deadband
but within the pulse band. The “c” contact is pulsing at the
programmed time intervals.

-->C When this symbol appears, the value of the analog input
associated with the control output is above the pulse band.
The “c” contact is closed, and the controlled device is
moving full speed toward the cooling position.

->H When this symbol appears, the value of the analog input
associated with the control output is below the deadband
but within the pulse band. The “h” contact is pulsing at the
programmed time intervals.

-->H When this symbol appears, the value of the analog input
associated with the control output is below the pulse band.
The “h” contact is closed, and the controlled device is
moving full speed toward the heating position.

Sched Status

The binary input which is controlling the schedule of the control
output is shown here along with a plus (+) or minus (-) sign. The plus
and minus signs indicate the present status (“ON” or “OFF” state)
of the input value which is controlling the schedule. For example,
if week schedule W1 has been input to control the schedule on
an EA Driver Screen, the message “+ W1” will appear here when
week schedule #1 is “ON,” and “- W1” will appear when week
schedule #1 is “OFF.”

Mode

One of the following messages may be displayed here:

altl: This message is to inform you that a control output using

the time clock mode is in the primary alternate mode. When
the status (“ON” or “OFF” state) of the [binary] input
value which has been entered on the Control Output Screen
to select the primary alternate mode is “ON,” the “altl”
message will be displayed here.

alt2: This message is to inform you that a control output using

the time clock mode is in the secondary alternate mode.
When the status (“ON” or “OFF” state) of the [binary] input
value which has been entered on the Control Output Screen
to select the secondary alternate mode is “ON,” the “alt2”
message will be displayed here.

loc: This message is to inform you that the control outputs are

in the local set mode. This message will appear if the small
toggle switch on the front of the satellite controller labeled
“local set” is in the on position. This message will also
appear when the satellite is going through a power up delay.
The power up delay allows the ECC/WCC II system to
soft-start the equipment after a power failure. When power
is restored to a satellite, the output contacts will remain open
for an adjustable amount of time. The delay time is entered
for each satellite controller on the satellite summary screen.

CAUTION: Note that the contact outputs in the satellite
controller will remain open during the power up delay time.
This should be taken into consideration when you are deciding
whether an open contact in the satellite should cause the
equipment to be ON or OFF.

revr: This message appears when the control output is in the

reverse acting mode (EA Driver Screen only.)

ovr:

Analog Control Input

When using the Dual Limit Screen, this message will appear
when the output has been overridden from the Override
Screen.

The value of the analog input associated with the EA Driver and
Dual Limit Screens will automatically be displayed here.

Specifi es the binary (On/Off) point address used to schedule
this control output. When this address is zero (or OFF), the OFF
schedule mode is selected; when it is one (or ON), the ON schedule
mode is selected.

COM to H makes on Decreasing Control Signal
COM to C makes on Increasing Control Signal

Displayed by the system as a reminder of the function of the output
contacts in the EA Driver mode. The EA Driver mode uses two of
the SAT II binary output contacts. The COM to H contact closes
to complete a 24 VAC signal when the value of the analog input is
less than the setpoint. The COM to C contact closes to complete a
24 VAC signal when the value of the analog input is greater than
the setpoint.

Hysteresis: = _____ x 0.1

Hysteresis is a software entry that allows an operator to specify
how much a measure variable, such as room temperature, has to
change before the switch changes state. For example, consider
a temperature setpoint of 72 °F with a +/-0.5 °F hysteresis. The
switch will change state (open/close) when the temperature rises
to 72.5 °F and will not switch back to its original state until the
temperature drops to 71.5 °F.

The multiplier is automatically selected based on the data pattern
for the analog input associated with this screen. If the data pattern
is xxx.x, then 0.1 will appear as the multiplier. If a +/-0.5 hysteresis
is desired, input 5, and the system will multiply 5 by 0.1 to equal

0.5.

Specifi es the number of the satellite you are currently editing. If
you would like to edit a different satellite, position the cursor to this
fi eld by using the cursor positioning (arrow) keys, enter the desired
satellite number, and press <Enter>.

Trend Log #: ____

This fi eld actually contains two separate fi elds. The fi rst fi eld
specifi es the point “type” (i.e., analog input, control output, analog
output, etc.) and displays the current type in textual form. Because
this is a “choice” fi eld, the list of available choices will be displayed
at the bottom of the screen:

CHOICES: <Anal, Cont, Anal, Trend, Logi, TUC>

Make your selection by pressing the <space bar> once for each
choice until the desired point type has been selected. (If you select
a point type that is different than that currently being displayed, the
screen will be rewritten with the appropriate screen and data.)

The second fi eld specifi es the point number to edit. For the Trend
Log Screen, this number can range from one to eight. If you would
like to edit a different point, simply position the cursor to this fi eld
by using the cursor positioning (arrow) keys, enter the desired
point number, and press <Enter>.

of Type:

Specifi es which of the four available trend logging modes (analog
peak, analog trend, change-of-state, and run time) you wish to use.
Because this is a “choice” fi eld, the list of available choices will be
displayed at the bottom of the screen:

CHOICES: <ANALOG TR, ANALOG PE, CHANGE OF, RUN TI>

To make your selection, press the <space bar> once for each
choice until the desired mode has been selected, and then press

<Enter>. (When you select a trend logging mode that is different

than that currently being displayed, the screen will be rewritten
with the appropriate screen and data.)

Records time and date of high & low peaks for:

Specifi es the analog point address for which the analog peaks (high
and low) are to be recorded.

Starting at: 00:00 on 00/00

Specifi es the time and date that the trend log recording should begin.
(The time is represented in 24-hour format.) The system considers
*’s in these positions to be “wild cards.” Therefore, if you want the
system to always log the low and high peaks independent of the
time and dates, enter “*.* on */*.”

Reset by ______ being ____.

Specifi es the [binary] point address that will be used to reset (or
clear) the record trend log data. The fi rst fi eld specifi es the point
address, and the second specifi es the state or condition that the
point address needs to be in in order to clear the data.

Last Low Peak: 00.0 at 00:00 on 00/00
Last High Peak: 00.0 at 00:00 on 00/00

This is the actual trend log data. It is displayed by the system from
information received by the satellite. It details the value of the high
and low peaks and the time and date of their occurrence.

Press <Ctrl><R> to Reset Data

If you want to reset (clear) the existing trend log data, you may do
so by pressing and holding <Ctrl> and then pressing <R>. After
several seconds this will automatically reset (clear) the data on the
Trend Log Screen (you must leave the screen and come back to it
for the screen to clear). On new systems, each Trend Log Screen
should be reset after it has been programmed to clear out any
“random data” that might be in the satellite controller.

Pending:

If the system has detected an alarm but has not reported it on the
local or remote printer, a message will show up indicating an alarm
is pending. PRT will appear when an alarm is waiting to print on
the local printer, and CAL will appear when an alarm is waiting to
call out. If the local has been disabled using the System Parameter
II Screen, the PRT message will not appear.

Description:

This location displays the description message of the address.
This information comes from the description area of the screen
corresponding to that particular address.

Alarm Message(s):

This location will display the alarm message associated with the
particular alarm. If the address was assigned two alarm messages
(a low message and a high message), the alarm which is initiated
fi rst will appear under the Alarm Message(s) section. If a second
alarm exists, it will appear after the fi rst message which is located
under the time and date location.

If you have a high and/or low alarm message and wish to see at
what time and on what day the alarm occurred, you will need to
go to the summary screen for the particular address to view this
information.

If you would like to acknowledge all of the alarms at once, press

<Alt> and <A> simultaneously while the cursor is at the top of this

screen.

Clearing Random Data in Satellite
Run Time Registers

You may see some blank lines between two actual alarms on the
Alarm Summary Screen the fi rst time the ECC/WCC II system is
brought on line. These blank lines are caused by random data in
a satellite run time register the fi rst time a satellite controller is
powered up. If these registers are not cleared, the speed at which
the ECC/WCC II system can move from screen to screen will be
much slower.

To fi nd which satellite run time registers need to be reset, use the
arrow keys to move the cursor to one of the blank lines on the
Alarm Summary Screen and press <Enter>. The Run Time Screen
that needs to be reset will appear on the screen.

Enter data in the Run Time Screen as shown below:

Sat #:

Twenty satellites will appear on each Satellite Summary Screen.
If your system has more than twenty satellites, to view the next
twenty satellites, simply press <PgDn> (Page Down) located on
the keypad to the right of the keyboard. To view the previous
twenty satellites, simply press <PgUp> (Page Up) also located on
the keypad.

When fi rst entering this Satellite Summary Screen, you will
experience a slight delay in acquiring information on the screen.
This is because the system needs to travel the entire communication
loop to gather the information needed for this particular segment
of the program.

Location:

This location is a user entered message which may pertain to the
name of the satellite, the location of the satellite, etc.

3-38

If you are adding satellites to an existing system, you will not see
the new satellites on this screen until you have rebuilt the data
tables for these satellites. With any new hardware additions (adding
new satellites, optional boards, etc.), you MUST rebuild the table
for the particular satellite controller using the new hardware. Also,
whenever you receive and install a new version of ECC/WCC II
software, you MUST rebuild the ENTIRE table for the ENTIRE
system. For further information on rebuilding the table for the
system, consult the Special Purpose Keys section on page 3-1 of
this guide.

Power-Up Delay:

This feature allows the ECC/WCC II system to soft-start a building
after a main power failure. If power is lost to the building, the
satellites cannot control any of the equipment because everything
will be off. When power is restored, the binary output contacts on
the satellite controller will remain open for the power up delay
time, thus holding the equipment off. You may want to bring on a
critical satellite fi rst (lighting) and less critical satellites later.

Operator Interfaces

Caution: Please note that the contacts in the SATELLITE

will remain open during the power up delay time. This should

be taken into consideration when you are deciding whether an

open contact in the satellite should cause the equipment to be

ON or OFF.

Specifi c points may be soft-started within the satellite by using the
Shed/Restore Programs. (For more information, consult the Shed/
Restore Programs section on page 3-89 of this guide.)

WCC II Operator’s Guide

Section 3: Screen Descriptions

Time Date

The present time and date will automatically appear in these
locations.

VER:

The satellite controllers have their own software. This location will
tell you what version of software your satellite controllers have.
This is necessary for any updates or changes in software for the
satellites in the future.

ERR:

An asterisk (*) will appear to the right of the entered time when the
satellite is presently in the power up delay mode.

Alarms by class:

This location will display the eight alarm classes associated with
each satellite. When there is an alarm type active within the satellite,
the alarm type number will be in reverse-video. This will aid you in
acknowledging alarm conditions present within the satellite. After
viewing the alarm, you should go to the Alarm Summary Screen to
locate the alarm specifi cally.

LOC:

The “loc” message will appear if the “local set” switch on the front
of the satellite controller is in the ON position, causing the satellite
controller to operate in its local set mode.

TST:

This location will designate if you are operating the satellite
controller in the test mode. The test mode is active if the test switch
on the front of the satellite controller is in the on position. The test
mode can be used to check out the operation of the system. For
example, if a piece of equipment is controlled using the time clock
mode, “TEST” can be input as the binary value which closes the
contact to run the piece of equipment in question. To make sure the
system works properly, place the test switch in the on position and
the contact on the satellite controller should close to run the piece
of equipment in question.

This location is generally used by Temperature Industries for
monitoring transmission and receiving errors. We must monitor
such information to aid in trouble-shooting various problems
associated with the communications of the system.

SOS

If the system determines that a satellite controller has stopped
communicating, an SOS (Satellite Out of Service) message will
appear on the screen. The system will automatically give this alarm
a priority 1, and it will print-out and call-out.

To activate this feature, the satellite tables must be rebuilt (see
Utility Screen - Rebuild Satellite Table on page 3-98). Once the
system “sees” the satellite controller by rebuilding the table, it will
give an SOS alarm if the satellite controller is missing.

TYPE

The satellite type will appear here, either a Sat II, Sat II-A, or Sat
II-B.

Section 3: Screen Descriptions

Alarm Type Disabled by Calls Phone #’s

Eight alarm types can be entered on the various screens that have
alarm limits. The fi rst fi ve alarm types can be reported to a remote
printer over standard telephone lines.

The “Disabled by” column specifi es the [binary] point address that
disables the alarm call out feature. When this address is zero (or
OFF), the alarm call out feature is active; when it is one (or ON),
the alarm call-out feature is disabled. For example, assume you
want to call a remote printer at your house if an alarm occurs during
non-working hours, but you don’t want the system to call when
you are at work. You can create a week schedule, Week Schedule
#1 (W1) for example, that is “ON” during your normal working
hours. If W1 is entered as the “Disabled by” input, then the system
will not call out if an alarm occurs while W1 is “ON.”

The “Calls Phone #’s” column specifi es two telephone numbers
that are to be used in the event of an alarm. The system will attempt
to use the “1st” phone number. If this number does not answer,
the system will then attempt to use the “ALT” phone number, if
specifi ed. (The system will alternate between the 1st and ALT
phone numbers until one of them answers.) The system must
connect with a modem and must “dump” all of its information. If it
doesn’t, it will call again. If only one number is supplied (either 1st
or ALT), the system will attempt to call out using only that number.
You may enter up to 30 characters (control codes, ALT codes, and
the double quote character are not allowed).

If you want the system to report the alarm to both telephone
numbers, access the Utility Screen from the Main Menu and then
access the System Parameters II Screen. You may instruct the
system to call “either” or “both” telephone numbers for each alarm
type.

General Edit Allowed

This privilege level (Level 1) allows the operator to view all screens
and edit selected portions of each screen. In general, the operator
may edit any item for a particular point, but may not change the
point’s type (e.g., the operator may not change a point set to the
Dual-Limit mode to the EA Driver mode).

Effect Screen Edit

This privilege level (Level 2) allows the operator to view all screens
and edit most portions of the program except operator password
codes and other “sensitive” information.

View All Codes

This is the highest privilege level possible (Level 3) within the
system. At this level, the operator can perform all of the functions
allowed by the lower levels as well as gain access to the operator
password codes and other “sensitive” information.

Time out:

The time out feature causes the ECC/WCC II system to
automatically “sign off” if there has not been any keyboard activity
for the input amount of time. The system will reset the access level
to zero which will allow the user to view screens only.

Remote Printer:

The ECC/WCC II system has the capability of automatically
calling-out over standard telephone lines and printing alarms as
they occur on a remote printer. The ECC/WCC II system will
support two different printers—an Okidata 82A or Okidata 182.
The operator needs to designate which remote printer is used with
the system using this input.

Current Operator: Code:

Each operator is assigned a password which consists of a 5 digit
operator ID and a 4 digit code. When an operator signs on, he or
she must enter their 5 digit Operator ID at the “Current Operator”
location and press <Enter>. The cursor will move to the right
and await the code. The operator then enters the 4 digit code and
presses <Enter> again. The “View Screen Only” message in the
lower right hand corner of this screen will change to indicate which
level of access the operator has.

View Screen Only

This is the lowest privilege level possible (Level 0) within the
system. At this level, the operator can only view the various
screens. No editing of data is allowed.

Section 3: Screen Descriptions

SATELLITE SAVE/RESTORE

The data which is entered on the following ECC/WCC II screens
is stored in the memory of the satellite controllers and is not stored
in the CPU (personal computer):

1) Analog Inputs

2) Control Outputs

3) Analog Outputs

4) Trend Logs

5) Logic Switches

6) TUC

However, you have the option of saving the information which is
in the satellite controllers on a disk in the Central Processing Unit
(CPU) to allow you to have a back-up copy of the satellite data. We
strongly encourage you to do this to avoid the possibility of having
to manually re-enter satellite data.

The satellite data may be saved on a disk which is in the CPU
(personal computer) located at the building being controlled, or if
you have our remote communications software, you may save this
information on a disk in a remote computer which communicates
with the CPU over telephone lines.

System Disk

The system disk has the computer programs, or “code”, on it
which enables the CPU to operate as an energy management
and temperature control system. This disk stays in drive A or B
(depending on the version of software) on dual disk systems
(dual fl oppy disk drives). If your system has a hard disk drive, the
information from this disk is loaded onto the hard disk (drive C).

Data Disk

The information which is entered on the screens in the “Overview”
and “Central Unit” categories of the Main Menu is automatically
saved on the data disk. This disk stays in drive A or B (depending
on the version of software) on dual disk systems. If your system
has a hard disk drive, the information is automatically saved on the
hard disk (drive C).

Satellite Backup Disk(s)

Data from the satellite controllers is copied onto the satellite
backup disk. If you have a dual disk drive system, the satellite
backup disk(s) is not kept in the CPU, but should be kept in a safe,
dry, dirt and dust free location. If your system has a hard disk drive,
this information is kept on the hard disk (drive C).

Change Path

The information for up to 240 satellite controllers may be saved
on a hard disk, or information for up to 10 satellite controllers may
be saved on one 5¼” fl oppy disk or 20 satellites on a 3½” disk.
Before the system saves the data on the disk, it checks to see if data
for the particular satellite already exists on the disk. If it does, the
information which is already on the disk is put in a back-up fi le, and
the new information is saved in a new data fi le. Therefore, when
you are saving the information from the satellites for the fi rst time,
it is possible to get the data from 20 satellite controllers on one 5¼”
fl oppy disk. However, the next time you try and save the data, you
will get a “disk full” message due to the system making the back­up fi les. If your system has more than 10 satellites controllers, and
your CPU has dual fl oppy 5¼” disk drives, then we recommend
saving satellites 1-10 on one disk, 11-20 on the next disk, etc.

An ECC/WCC II system requires a System Disk, a Data disk, and
a Satellite Backup Disk(s). We recommend keeping a backup copy
of these disks, especially if you have a CPU with a hard disk drive.
See the Section in this manual titled, “Initiating the System” for
additional information on making backup disks.

The system will automatically save the information from the
satellite controllers on the same drive as the Data Disk which is
shown on the heading of this screen after “Satellite File Directory.”
If you would like to save the data to a different disk drive, follow
these instructions:

Access the System Parameters Screen and sign on by

1.
entering your password. You must have a level 3 access
code to perform this operation.

Return to the Main Menu and place the cursor over the

following screen should appear:

---------------------------------------------

--SATELLITE <--> DISK Operations -- Satellite
File Directory: a:\

Copy from Satellite #:

Specifi es the number of the satellite which has the information
which will be transferred to the other satellites(s).

Copy to Satellite #:

Specifi es the number for the satellite(s) which will receive the
information. You may input multiple satellites in this location
by using commas between and/or two (2) periods for strings of
satellites as in the example below:

Copy from Satellite # : 2
Copy to Satellite # : 4, 6, 12, 21..27, 57, 158

Allow overwrite of valid structures in destination
satellite ? NO

You are given the choice of a YES or a NO answer for this question.
When in this area of the screen, you may simply toggle the choices
by pressing the

<Enter> to enter the choice. If the satellite which is receiving the

information has previously been programmed, but you would like
to over-write what is presently in it, enter YES. If you want to save
what is already in the satellite which is receiving the information,
but want the new information to be copied onto screens that are
presently blank, enter NO.

For example, if you are copying from satellite #1 to satellites #2
and #3, but satellite #3 has good information which you would like
to keep and #2 does not, then you would choose NO for this choice,
so that the valid structures in #3 would not be written over.

Include non-valid structures from source satellite in
copy ? NO

You are given the choice of a YES or NO answer for this question.
When in this area of the screen, you may simply toggle the choices
by pressing the <space bar> on the keyboard and then pressing

<Enter> to accept the choice. If you do not want to include non-

valid structures (such as blank screens) from the satellite which is
sending the information, then a NO answer should be left in this
location. If you wish to include any non-valid structures (such as
blank screens) from the satellite you are copying from, then a YES
answer should be applied to this location.

You will generally leave the “NO” answer in this location. There are
not very many times non-valid structures from the source satellite
need to be included. This selection is generally used in trouble­shooting to distinguish between a problem with the satellite’s
processor and the CPU processor by duplicating the programming
in the memory from one satellite controller to another.

<space bar> on the keyboard and then pressing

When at the screen that has the information which is to be
transferred to the other screen, the cursor may be at any place on
the screen. Press <Alt> and then press <F>, holding both keys
down for an instant and then releasing both keys. The system will
automatically beep three times, and the following message will be
displayed at the bottom of the screen:

Point ___ of Satellite ___ was tagged for copy!

For example, if you want to copy from analog input #2 to analog
input #7 on satellite #183, the message would read:

Point 2 of Satellite 183 was tagged for copy!

After this portion of the process has been completed, you need to
move the cursor to the Home position of the screen which will
receive the new information. Once you are at this HOME position,
press <Alt> and then press <C>, holding both keys down for an
instant and then releasing both keys. The system will automatically
beep three times, and the screen will be fi lled in with the new
information. The copying process has been completed.

This copying process must be done for each screen you wish to
copy. You cannot tag one point and copy this point to three other
points.

If you “Tag” a point to be copied and suddenly change your mind,
you can perform one of the following two procedures:

Go HOME to the Main Menu. This will clear out the

1.
copying command.

You can make changes to the screen and Re-Tag the

2.
screen or go to another screen and Tag it. The last screen
Tagged will be the screen to be copied from.

Are you ready for the copy to begin ? YES

When you are ready for the copy process to begin, simply change
the “NO” to a “YES” by pressing the <space bar> while at this

OPTIMAL START #_____

Specifi es the number of the optimal start program you are currently
editing. The ECC/WCC II will accept up to 64 optimal start
programs.

The optimal start programs are referred to as S1 to S64. If a piece
of equipment is to be optimally started, then Sn (n being a number
from 1 to 64) is used for the schedule on the Control Output Screen
for that piece of equipment. If the week schedule that the optimal
start program is based on is input as the schedule for the control
output, the control output will not operate based on the optimal
start schedule. The Sn designation must be used to utilize the
optimal start program. The Sn designation may be input directly in
the Control Output Screen or used in a binary global.

BASED ON SCHEDULE:

Specifi es the time period for which the building is to be at the “ON”
schedule temperature. For example, if the user enters W1 (week
schedule #1), and W1 is “ON” from 8:00 am to 5:00 pm, then the

ECC/WCC II system will start the equipment early enough in the
morning to have the space temperature at the target temperature
when the occupants arrive at 8:00 am.

OUTDOOR SENSOR:
INDOOR SENSOR:

Specifi es the location of the indoor and outdoor temperature
sensors to be used with this optimal start program. For example,
if the outdoor air temperature sensor is wired to analog input A3
on satellite number 1, 1A3 may be input for the outdoor air sensor.
Or, you may want to use a global analog which would allow you to
average or sort the temperature of several zones.

MODE:

Specifi es the mode to be used. Because this is a choice fi eld, the list
of available choices will be displayed at the bottom of the page.

<LOCKED, ADAPTIVE, DISABLED>

Operator Interfaces

3-57

WCC II Operator’s Guide

Section 3: Screen Descriptions

Locked:

The system will use the advanced time variable specifi ed by the
user and will not adjust these values.

Adaptive:

The system will automatically adjust the advance start time based
on previous system performance. This allows the ECC/WCC II
system to “fi ne tune” the morning start time so your building is at
the target temperature when the schedule it has been assigned to
goes ON.

Disabled:

The optimal start will be disabled when this choice has been
selected. The optimal start will have no effect and the value input
for the “based on schedule” category of this optimal start will
provide the on/off schedule for the equipment.

STATUS

The Optimal Start Screen will automatically display one of the
four messages below:

Status: <OFF, ON SCHEDULE, COOL START, HEAT START>

The messages correspond with the following descriptions below:

The cooling target temperature MUST be greater than the heating
target temperature. Also, the cooling target temperature must be
greater than or equal to the ON schedule setpoint of the zone in
question, and the heating target temperature must be less than or
equal to the ON schedule setpoint of the zone in question.

LAST START OCCURRED AT _____ ON _____

The system will automatically fi ll in the time and date of last start.
This permits the user to check the system during the day to observe
when the Optimal Start Program began.

A Change-Of-State Trend Log may also be used to log the start and
stop time of the Optimal Start. To use the Change-Of-State Trend
Log, record the change of state for Sn (n being a number from 1 to
64 which corresponds to the optimal start in question).

with Indoor =
with Outdoor =

When the last start occurred, the Outdoor and Indoor temperatures
at the time of the start will automatically be recorded and displayed.
This will aid you in monitoring the Optimal Start Programs for
your system.

more than 5 minutes before the week schedule went on.

Done Late: The space temperature was at target temperature more

than 5 minutes after the week schedule went on.

COOLING TARGET: _____ °F
HEATING TARGET: _____ °F

Specifi es the desired temperature to be maintained in the space by
the time the schedule associated with the optimal start goes on.

Locked Mode

The “required major adjustment” message will appear when
the Optimal Start Screen is in the “locked mode” if the space
temperature did not reach target temperature within 2 minutes of
when the week schedule for this screen went ON.

Adaptive Mode

The “required major adjustment” message will appear when
the Optimal Start Screen is in the “adaptive mode” if the target
temperature was not reached within the number of minutes
equal to the difference between the actual temperature and target
temperature when the optimal start began. That is, if there was
a 10 °F difference between the actual temperature and the target
temperature when the Optimal Start Program began, then the
“required major adjustment” message will appear if the space
temperature did not reach target temperature within 10 minutes of
when the week schedule went ON.

within normal tolerance -

Locked Mode

The “within normal tolerance” message will appear when the
Optimal Start Screen is in the locked mode when the space
temperature reaches the target temperature within 2 minutes of
when the week schedule for this screen goes ON.

Adaptive Mode

The “within normal tolerance” message will appear when the
Optimal Start Screen is in the “adaptive mode” if the space
temperature reaches the target temperature within the number of
minutes equal to the difference between the actual temperature
and target temperature when the optimal start began. That is, if
there was a 10 °F difference between the actual temperature and
the target temperature when the Optimal Start Program began, then
the “within normal tolerance” message will appear if the space
temperature was at the target temperature within 10 minutes of
when the week schedule went ON.

OUTDOOR READING

Enter two values under the outdoor reading heading—the top
value and the bottom value. The computer automatically fi lls in the
values between these two numbers at even increments. Usually, the
highest outdoor air temperature expected is input at the top, and the
lowest outdoor air temperature expected is input at the bottom.

ADVANCE TIME

For example, assume the outdoor temperature is 45 ºF, the indoor
temperature is 65 ºF, and the indoor target temperature is 70 ºF.

Outdoor Temperature: 45 ºF
Indoor Temperature : 65 ºF
Target Temperature : 70 ºF

From the Advance Start Table, the advance start time is 12.11
minutes per ºF.

The difference between the indoor and target temperatures is
5 ºF.

Target Temperature: 70 ºF
Indoor Temperature: 65 ºF

----------­ Difference: 5 ºF

Therefore, the advance start time is 60.55 minutes.

12.11 x 5 = 60.55 MINUTES EARLY START

If you have selected the “adaptive” mode, and the space temperature
does not reach the target temperature when the schedule associated
with this optimal start program goes ON, the system will
automatically increase the advance start time. If the space reaches
the indoor target temperature before the schedule goes ON, then
the system will automatically reduce the advance start time.

This is a user-entered fi eld which corresponds with the Outdoor
reading. These values also correspond with the message to its right
which states:

Advance time is measured in minutes/1.0 Deg F
difference between indoor and target

In the LOCKED mode, the system will always use these advance
start times. In the ADAPTIVE mode, the system will automatically
adjust these values based on previous system performance.

The Optimal Start Program reads the indoor temperature and
calculates how far it is away from the target temperature. It also
reads the outdoor temperature and then determines the start time
needed to bring the building to the target temperature. The largest
number which may be entered in this position is 99.99.

ANALOG GLOBALS

The ECC/WCC II system has 128 analog globals. The term
“ analog” means a numerical value represented by a directly
measurable quantity such as temperature, pressure, etc. The
term “ global” means information which is shared by all of the
satellite controllers in the system. Therefore, an “analog global”
is a numerical value which can be used by any satellite controller
within the ECC/WCC II system.

An ECC/WCC II system has the capability of generating the value
of the analog globals by the following methods:

Averaging several numerical values

•

•

Sorting several numerical values to fi nd the highest
number, lowest number, or any number in between

Calculating a “sliding window” average

•

•

Averaging one value over a period of time

•

Add data readings together to obtain an
accumulated total

•

Math functions

•

Look up tables

Value to be averaged

You may input up to 8 analog values to be averaged. The values
may be input in the form of 12A4 (analog input #4 on satellite
controller #12) or GA20 (global analog #20).

If a satellite controller that has an analog input used on this screen
stops communicating, then a value will be missing from the list.
The statement at the bottom of the screen allows you to specify a
default value for the missing values. However, if several inputs are
missing, you may default to a fi xed value. Consider the following
example:

Substitute 72 for each unavailable value until more than 3 values
are unavailable, and then use 70 as the value for this global.

If one analog input on this screen is lost, then 72 will be substituted
for the lost value. If more than 3 analog input values are missing
from this screen, the value of the global will default to 70.

Range

The system has the capability of generating an alarm if the value
of this global analog is either inside or outside of the desired range.
If inside is selected, an alarm will be generated when the value of
the global analog is within the two limits specifi ed. If outside is
selected, an alarm will be generated if the value of the global is
outside the limits specifi ed.

Values to be sorted

You may input up to 8 analog values to be sorted. The values may
be input in the form of 12A4 (analog input #4 on satellite controller
#12) or GA20 (global analog #20). The values of the analog inputs
on this screen will be sorted from the lowest to the highest. For
example, assume that the following analog inputs have been
entered on this screen as values to be sorted:

5A4 7A6 22A1 13A3 _____ _____ _____ ___

Assume:

The value of analog input #4 on satellite #5 (5A4) = 76 º F
The value of analog input #6 on satellite #7 (7A6) = 72 º F
The value of analog input #1 on satellite #22 (22A1) = 70 º F
The value of analog input #3 on satellite #13 (13A3) = 74 º F

The system will order the values from the lowest to the highest
as shown below:

1 2 3 4

---- ---- ---- ---­ 70 72 74 76

You may designate the value of this global to be any of these four
values. Let’s assume that we want the value of this global to be the
next highest of the sorted values. Therefore we would input a 3 for
the sorted list element #.

Global value = sorted list element #: 3

list. The statement at the bottom of the screen allows you to specify
a default value. If several inputs are missing, you may default to a
fi xed value. Consider the following example:

If more than 3 values are unavailable, then use 74 as the value
for this global.

If more than 3 inputs are lost, the global will no longer sort the
list, but default to 74.

Range

The system has the capability of generating an alarm if the value
of this global analog is either inside or outside of the desired range.
If inside is selected, an alarm will be generated when the value of
the global analog is within the two limits specifi ed. If outside is
selected, an alarm will be generated if the value of the global is
outside the limits specifi ed.

If you select Value as the choice for this fi eld, you can enter a
number which will serve as the alarm limit.

The value of the global analog would be 74 in this example
since 74 is number 3 in the ordered list.

ANALOG GLOBAL - INTEGRAL

MODE

The integral mode can be used to either determine the average
value of a measured variable using a “sliding window” effect or the
straight average for a given time period. The integral may also be
used to add data readings together to obtain an accumulated total.

SLIDING WINDOW

Assume that we want to know the
average kW demand of a building over
a 30 minute time period. The ECC/WCC
II system will take a kW reading at
programmed time intervals; for example,
1 reading every three minutes. The value
of the analog global will be the average
kW for the 10 most recent readings. To
understand this mode better, think of
the data as being in a “window” which
moves along the time axis and has the 10
most recent kW readings in it. The value
of the analog global is the average of the
kW values that are in the window. As

the next kW reading becomes available,
the oldest kW reading in the window drops off and is no longer
included in the data set which is used to determine the value of the
global analog.

Sampling From:

The value of the global analog will be the average of this input
using the sliding window averaging method.

For example, if 3A1 is input here, the system will periodically read
the value of analog input #1 on satellite controller #3. The value of
the global analog will be the average of several of the most recent
readings, depending on how other inputs on this screen are fi lled
out.

Automatically reset by GB1 being OFF

This allows you to have the system automatically restart the

There are three integral modes which can be selected by pressing
the <space bar> until the desired choice appears, and then pressing

<Enter>. The following choices are available:

<Sliding Window, Average, Accumulation>

Divisor: 1

Due to memory limitations within the ECC/WCC II system, the
maximum value of any global analog is 65,535, and the largest
