Wiring & Connection Diagram
Component & System Wiring 19

Systems Overview
General Information
The Orion system components can be configured into several types of
systems. It is a good idea to become familiar with the different types of
systems and their architecture by reading the information in this section
and looking at the configuration diagrams in the System Configurations
Installation & Commissioning section of this manual. The information
below is designed to help you understand how the system components
integrate with each other and the available configuration options.
System Types
Four different system configurations are available depending on the
type and number of controllers that you have on your system.
1. Stand Alone
(See Pages 6 Through 8 For Connection Diagrams)
2. Interconnected
(See Pages 9 Through 11 For Connection Diagrams)
3. Networked Single Loop
(See Pages 12 Through 16 For Connection Diagrams)
4. Networked Multiple Loop
(See Pages 17 Through 19 For Connection Diagrams)
System Type Definitions
Stand Alone
This system consists of a single VCM controller. Programming and
status monitoring are accomplished by one or more of the following
methods.
1. By using an operator interface. This can be either a
Modular System Manager, a Modular Service Tool or both
devices.
2. A computer interface can also be used in conjunction with
the other operators interfaces listed above, or by itself. This
requires a CommLink and a personal computer with the
Prism computer front end software installed.
Interconnected
This system consists of a group of VCM Controllers interconnected
with communication cable to allow programming from one central location.
Broadcasting between controllers is not available. Programming
and status monitoring are accomplished by one or more of the following
methods.
1. By using an operator interface. This can be either a
Modular System Manager, a Modular Service Tool or both
devices.
2. A computer interface can also be used in conjunction with
the other operators interfaces listed above, or by itself. This
requires a CommLink and a personal computer with the
Prism computer front end software installed.
Networked Single Loop
The Networked Single Loop system, as its name implies, consists of a
single communications loop. This loop utilizes a network device to share
information that is broadcast from one controller to all controllers on
the loop. The system can consist of the following devices.
1. A series of VCM Controllers that utilizes a
network device to share information that is broadcast from
one controller to all controllers on the loop.
2. A single VCM controller and a series of VAV/Zone
controllers. A network device is used to share information
which is broadcast back and forth between all controllers
on the loop.
These systems require a network device in the form of either a CommLink
communications interface or a MiniLink Polling Device. Both network
devices may also be used together. Programming and status monitoring
are accomplished by the following methods.
1. By using an operator interface. This can be either a
Modular System Manager, a Modular Service Tool or both
devices.
2. A computer interface can also be used in conjunction with
the other operators interfaces listed above, or by itself. This
requires a CommLink and a personal computer with the
Prism computer front end software installed.
When using the MiniLink Polling Device alone, only the System Manager
or Modular Service Tool can be used to program and monitor the
system. With the addition of the CommLink, the Prism computer front
end software and a PC can be used to program and monitor the system
in addition to the Modular Service Tool or Modular System Manager.
Networked Multiple Loop
This Networked Multiple Loop System consists of two or more loops,
each being called ‘Local Loops’, with one ‘Network Loop’ that ties the
“Local Loops” together. Each of these loops can consist of one of the
following groups of controllers.
1. A series of VCM controllers.
2. A single VCM controller and a series of VAV/Zone
controllers.
To form the Networked Multiple Loop System the following network
devices are required.
1. A MiniLink Polling Device is required per loop (Local
Loop). This allows the controllers to share information that
is broadcast from one controller to all controllers on that
local loop.
2. One CommLink is required for the entire system. It resides
on the Network Loop and allows for communications
between all the local loops and provides for global
broadcasts to all controllers on the entire system.
20
Component & System Wiring

Programming and status monitoring are accomplished by one or more of
the following methods.
1. By using an operator interface. This can be either a
Modular System Manager, a Modular Service Tool or both
devices. The System Manager or Modular Service Tool
connect to any “Local Loop” on the system.
2. A computer interface can also be used in conjunction with
the other operators interfaces listed above, or by itself. This
requires a personal computer with the Prism computer front
end software installed.
Network Communications Devices
MiniLink Polling Device
The MiniLink Polling device is used in the following applications.
1. This device is required on all Zoning applications. It is
optional on single loop VAV systems.
2. This device is required on each local loop of all Networked
Multiple Loop systems
This device is responsible for local loop broadcasts only. It always resides
on the local loop.
For a Networked Single Loop VCM system, this device can be used for
tenant logging and alarm reporting to a Modular System Manager. It can
be used to broadcast information like outside air temperature or outside
air humidity to all devices on the local loop. It can also be used to
broadcast space temperature from a GPC Plus or GPC-17 controller to
any controllers on this loop that do not have their own space temperature
sensor.
For a Networked Single Loop VAV system, the MiniLink Polling Device
can be used for tenant logging and alarm reporting to a Modular
System Manager. It must be used to broadcast information such as, internal
schedule, supply air temperature, fan and heat status, unoccupied
calls for heating and cooling from the VAV/Zone controllers, and forced
modes of operation.
For a Networked Single Loop Zoning system, this device must be used
for zone voting, because it calculates the heating and cooling totals on
the loop and broadcasts cooling, venting, and heating modes to the VAV
controller. It can also be used for tenant logging and alarm reporting to
the Modular System Manager.
CommLink
The CommLink device is used in the following applications.
1. A CommLink is required on all Networked Multiple Loop
Systems
2. A CommLink is optional on all Networked Single Loop
Systems
3. A CommLink is required on any system when a computer
interface is desired
The CommLink is responsible for local loop broadcasts on a Networked
Single Loop system, and on this type of system, the on board jumper
must be set to “Single”. This device is responsible for network broadcasts
on Networked Multiple Loop systems. On this type of system, the
on board jumper must be set to “Multi”.
For a Networked Single Loop VCM system, this device can be used for
tenant logging and alarm reporting to a Modular System Manager. It can
also be used to broadcast information like outside air temperature or
outside air humidity to all local loops on the entire networked system.
It may also be used to broadcast space temperature from a GPC Plus or
GPC-17 controller to any controllers on the local loop that do not
contain their own space temperature sensor.
On a Networked Single Loop VAV/Zone system, the CommLink can be
used to broadcast information such as, internal schedule, supply air temperature,
fan and heat status, unoccupied calls for heating and cooling
and forced modes of operation to and from the VAV/Zone controllers.
System Installation
Wiring Considerations
Before beginning installation, please study the wiring diagrams for the
controllers you are using with your particular application. These diagrams
appear in this Component & System Wiring Technical Guide and
can also be found in the technical guide supplied with your specific
controllers. Wire and transformer sizing instructions and examples are
located on page 28 through 29 of this manual.
Most of the Orion controllers are equipped with modular connections,
and in some cases are equipped with both modular and wiring terminal
blocks. We recommend (when possible) using modular cables instead
of hard wiring to wiring terminal blocks, to save installation time and
eliminate wiring errors. In some cases, however, hard wiring is unavoidable.
The table below lists the various Orion devices/controllers
and their available termination type(s) for communications and power

Component & System Wiring 21

System Installation
Power/Comm Board Requirements
Standard Connection Configurations and Use
Power/Comm boards are typically used on Networked, Single and
Multiple Loop systems to transfer 24 VAC power and “Local Loop”
communications to VAV/Zone controllers, System Managers or other
Power/Comm boards.
The Power/Comm board must always be powered by its own dedicated
24 VAC transformer connected to it’s 2-wire, 24VAC input terminals
(TB1).
Local Loop communications are transferred to the Power/Comm Board
via a modular cable connected to its “Comm In” modular connector
input terminal (P2). This modular cable connection can originate from
the “Local Loop” modular connector of the MiniLink PD for this loop,
another Power/Comm board output on the same loop or a VAV/Zone
controller or System Manager output on the same loop. If desired a
Power/Comm board can be connected to the “Local Loop” by hard wiring
a 2-wire shielded cable connected between it’s 3-wire communications
input terminal (TB1) and a VCM controller, a Power/Comm
board or the MiniLink PD “Local Loop”, 3-wire communications terminal.
For detailed wiring diagrams, see the Power/Comm board wiring diagrams
in the “Communication Devices Diagrams” section of this
manual.
For Power/Comm board transformer sizing see the last 2 pages of the
“Systems Configurations Installation & Commissioning” section of
this manual.
Alternative Connection Configuration and Use
If desired, the Power/Comm board can also be used to transfer both 24
VAC power and “Network Loop” communications to multiple MiniLink
PDs. Connection between the MiniLink PD(s) and Power/Comm
board(s) is accomplished by using modular cables between the Power/
Comm boards modular output connectors and the MiniLink PD(s) “Network
Loop” modular input connectors. When a Power/Comm board is
used to connect power and communications to MiniLink PDs in this
manner, that particular Power/Comm board cannot also be used to share
communications and/or power with VAV/Zone controllers or System
Manager(s).
Warning: Do not ground the 24 VAC transformer that is to be
used with the Power/Comm board. Grounding of the
transformer will damage the Power/Comm board and
all boards connected to it. A separate transformer
must be used for each Power/Comm board. No
exceptions. Do not connect any other devices to the
transformer used for the Power/Comm board!
For detailed wiring diagrams, see the Power/Comm board wiring diagrams
in the “Communication Devices Diagrams” section of this
manual.
MiniLink Polling Device (MiniLink PD)
Standard Connection Configurations Use
The MiniLink PD is used on Networked Single and Multiple Loop
systems to provide two way communications between all devices on
it’s “Local Loop” and to all the other “Network Loop” devices on the
entire system. The MiniLink PD is equipped with both modular connectors
and hard wiring terminal blocks for connection of 24 VAC power,
“Local Loop” and “Network Loop” communications.
Each MiniLink PD is normally hard wired to a 24 VAC power source
connected to its 24 VAC input terminal (TB1). “Network Loop” communications
are transferred between multiple MiniLink PDs by modular
cables connected to their “Network Loop” modular connectors (P3
and P5). A CommLink must be connected to one of the MiniLink PDs
on the system by using a 2-wire shielded cable connected between its 3-
wire “Network Loop” communications terminal block (TB4) and to the
CommLink’s “485 Loop” terminals block. Transfer of “Local Loop”
communication from the MiniLink PD to a Power/Comm board is made
by using a modular cable connected between the MiniLink PD “Local
Loop” modular connector (P4) and the Power/Comm board modular
“Comm In” connector (P2). If desired as an alternative, transfer of
“Local Loop” communication from the MiniLink PD to a Power/Comm
board can be made by hard wiring a 2-wire shielded cable connected
between the MiniLink PD’s 3-wire communications terminal (TB1) and
the 3-wire communications input (TB1) on the Power/Comm Board.
Installation Procedures
The installation procedures that follow are based on recommended methods
of wiring connection and controller installation. Installation procedures

Transformer & Wire Sizing - Devices Without Modular Connectors
24VAC Power - Transformer & Wire Sizing Considerations for Devices Without Modular Connectors
Some installers like to use one large 24VAC transformer to power several devices. This is allowable as long as polarity is maintained to each device on
the transformer circuit. Warning: If polarity is not maintained, severe damage to the devices may result. WattMaster Controls recommends
using a separate transformer for each device in order to eliminate the potential for damaging controllers due to incorrect polarity. Using
separate transformers also allows redundancy in case of a transformer failure. Instead of having 8 controllers inoperative because of a malfunctioning
transformer you have only 1 controller off line. If the installer does decide to use a large transformer to supply power to several devices, the following
transformer and wire sizing information is presented to help the installer correctly supply 24VAC power to the devices.
Following is a typical example to help the installer to correctly evaluate transformer and wiring designs.
Each GPC Plus Controller requires 8 VA @ 24VAC power. In the examples below we have a total of 8 GPC Plus Controllers.
8 GPC Plus Controllers @ 8VA each................ 8 x 8VA = 64VA.
The above calculation determines that our transformer will need to be sized for a minimum of 64VA if we are to use one transformer to power all the
controllers.
Next we must determine the maximum length of run allowable for the wire gauge we wish to use in the installation. Each wire gauge below has a
voltage drop per foot value we use to calculate total voltage drop.
18ga wire.................................0.00054 = voltage drop per 1’ length of wire
16ga wire.................................0.00034 = voltage drop per 1’ length of wire
14ga wire.................................0.00021 = voltage drop per 1’ length of wire
For our example we will use 18 gauge wire. WattMaster recommends 18 gauge as a minimum wire size for all power wiring.
Next use the voltage drop per foot value for 18 gauge wire from the list above and multiply by the total VA load of the 8 controllers to be installed.
0.00054 (Voltage drop per foot for 18 gauge wire) x 64VA controller load = 0.0346 Volts/Ft.
WattMaster controllers will operate efficiently with a voltage drop no greater than 2 Volts. Divide the total allowable voltage drop of 2 Volts by the
number you arrived at above and you have the maximum number of feet you can run the 18 gauge wire with an 75 VA transformer with no more than a
2 Volt drop at the farthest controller from the transformer..
2 (Volts total allowable voltage drop)
= 57.80 feet
0.0346 (Voltage drop per 1 ft. @ 64VA load)
Parallel circuiting of the wiring instead of wiring all 8 controllers in series allows for longer wire runs to be used with the same size wire (as shown in
our examples below). It is often necessary for the installer to calculate and weigh the cost and installation advantages and disadvantages of wire size,
transformer size, multiple transformers, circuiting, etc., when laying out an installation. No matter what layout scheme is decided upon, it is mandatory
that the farthest controller on the circuit is supplied with a minimum of 22 Volts.

Transformer Sizing & Cabling - Devices With Modular Connectors
24VAC Power - Transformer & Cabling Considerations for Devices With Modular Connectors
Modular devices include the VAV/Zone Controller, Modular
System Manager & MiniLink Polling Device. When sizing
transformers for the devices it is important to design your
layout so that the fewest number of Power/Comm distribution
boards and the least number of transformers can be used.
The polarity problem discussed in regards to other devices
that do not have modular connections is not an issue with the
modular devices as they cannot be connected with reversed
polarity because of the modular board connectors and cable.
Also the prefabricated cable is always 16 gauge. Wire size
selection is therefore not an issue with the modular devices.
However, the same minimum voltage rules apply to modular
devices as with other non-modular devices. In order to
simplify wiring design and layout with modular devices the
following rules apply:
Power/Comm Board maximum transformer size = 100VA.
This is due to the board circuitry and fusing. Each modular
device is to be calculated at 6VA. This allows for a maximum
of 16 devices per Power/Commboard. If more than 16
devices are required, multiple Power/Comm boards must be
used.
No more than 6 modular devices allowed per branch circuit.
(The Power/Comm board has a total of 4 branch circuits)
The longest total run per branch circuit is 240 Ft. This is due
to voltage drop on the prefabricated cable.
Below are some examples of transformer sizing and branch
circuit design.
6 Devices Maximum Per Branch Circuit
16 Devices At 6 VA = 96 VA
Use 100 VA Transformer
13 Devices At 6 VA = 78 VA
Use 80 VA Transformer

WARNING!
DO NOT GROUND THE 24V TRANSFORMER THAT IS TO BE USED
WITH THE POWER/COMM BOARDS. GROUNDING OF THE
TRANSFORMER WILL DAMAGE THE POWER/COMM BOARD AND
ALL BOARDS CONNECTED TO IT. A SEPARATE TRANSFORMER
MUST BE USED FOR EACH POWER/COMMBOARD. NO
EXCEPTIONS. DO NOT CONNECT ANY OTHER DEVICES TO THE
TRANSFORMER USED FOR THE POWER/COMM BOARD!

Caution:
If your HVAC unit is supplied with the MODGAS II controller with or without an MHGRV II controller, the Supply Air Temperature
Sensor must always be wired to the MODGAS II controller. If your HVAC unit is supplied with only the MHGRV II controller, the
Supply Air Temperature Sensor must be connected to the MHGRV II controller. See the Miscellaneous Diagrams & Technical
Information section in the back of this manual for detailed connection diagrams when using MODGAS II or MHGRV II controllers.
If you have either of these controllers on your HVAC unit and connect a Supply Air Temperature Sensor to the VCM controller,
your controls will not function correctly. Only one Supply Air Temperature Sensor can be used on each HVAC unit.

*Chart Notes:
1. Use the resistance column to check the thermistor sensor while disconnected from the controllers (not powered). Connect as shown below.
2. Use the voltage column to check sensors while connected to powered controllers. Read voltage with meter set on DC volts. Place the sensor
leads as shown in the illustration below. If the voltage is above 5.08 VDC, then the sensor or wiring is "open." If the voltage is less than 0.05
VDC, the sensor or wiring is shorted.

Over Voltage Board Wiring
OE-268 Over Voltage Board
NOTE: This board goes between the supply transformers
low voltage output and the controllers low voltage input.
WattMaster Controllers do not like to see more than
28 VAC on their input side. When the line voltage to the
transformer is too high, generally the output side of the
transformer (low voltage) is too high, thus requiring this
Over Voltage Board.

Caution:
If your HVAC unit is supplied with the MODGAS II controller with or without an MHGRV II controller, the Supply Air Temperature Sensor must always
be wired to the MODGAS II controller. If your HVAC unit is supplied with only the MHGRV II controller, the Supply Air Temperature Sensor must be
connected to the MHGRV II controller. If you have either of these controllers on your HVAC unit and have a Supply Air Temperature Sensor connected
to the VCM controller, your controls will not function correctly. Only one Supply Air Temperature Sensor can be used on an HVAC unit.

VCM Controller with MODGAS II Only
If your HVAC unit is supplied with the MODGAS II controller with or without an MHGRV II controller,
the Supply Air Temperature Sensor must always be wired to the MODGAS II controller. If your HVAC
unit is supplied with only the MHGRV II controller, the Supply Air Temperature Sensor must be
connected to the MHGRV II controller. If you have either of these controllers on your HVAC unit and
have a Supply Air Temperature Sensor connected to th VCM controller, your controls will not function
correctly. Only one Supply Air Temperature Sensor can be used on an HVAC unit. If expansion boards
2
are used they can be connected via modular cable to any I C connector on the loop.

Chip Installation Procedures
Gently Rock Chip Side To Side And Then
Lift Straight Up To Remove Chip From
Chip Socket.
I.C. Puller
WARNING!
Be sure the chip you have selected to replace is a
socketed chip. Not all driver chips on the boards
are field replaceable. Only socketed chips may be
removed and replaced in the field. All other chips
that are not socketed will require sending the board
to the WattMaster factory for repair. If you try to
remove a chip that is not socketed it will destroy
the circuit board. Once you have determined that the
chip needing replacement is indeed a socketed chip
please proceed in the following manner.
Using I.C. Puller To Remove Socketed Chip
Chip
Chip Socket
Printed Circuit
Board
Remove the communications loop connector and
then the 24VAC power connector on the controller
before attempting to change any components.
DAMAGE will occur if components are removed or
installed with power applied.
If you are unsure how to safely remove the chip or
about the correct pin placement, please consult the
factory before proceeding.
Damage to the board caused by failure to correctly
remove or install the chip is not covered by the
WattMaster warranty.
Small Flathead
Screwdriver
Gently Lift The Chip On One End And Rock Chip
Back And Forth With Screwdriver As Shown.
Repeat This Process On The Other End Of Chip.
Alternate This Process On Both Ends Of Chip Until
The Chip Is Free From The Chip Socket.
Direction Of Pull
Chip
Use extreme care to avoid inserting the screwdriver
or I.C. Puller under the socket. You must insert the tip
of the screwdriver or ends of the I.C. Puller between
the body of the chip and the chip socket.
Each chip MUST be installed with Pin 1 in the correct
location. Installing the chip “backwards” will in most
cases destroy the device when power is reapplied.
Chip Socket
Pin 1 can be located by looking for the notch in the end
of the chip. Pin 1 on "some" chips is identified with a dot.
Using Screwdriver To Remove Socketed Chip
Printed Circuit
Board
Be certain that ALL pins are lined up in the socket
before pressing the chip in. Failure to properly line
up the pins will result in damage to the chip.
This is a VERY common error - BE CAREFUL.
Only after confirming that the chip has been correctly
installed with Pin 1 in the proper position and that the
pins are lined up and none are bent or out of the socket,
should communication or power wiring be reconnected
to the board. Tp prevent possible damage always
reconnect the power wiring first and then the
communication wiring.

Temperature & Humidity Sensor Voltage-Resistance Tables
Sensor Checks
The following sensor voltage and resistance tables are provided to aid
in checking sensors that appear to be operating incorrectly. Many system
operating problems can be traced to incorrect sensor wiring. Be
sure all sensors are wired per the wiring diagrams in this manual.
If the sensors still do not appear to be operating or reading correctly,
check voltage and/or resistance to confirm that the sensor is operating
correctly per the tables. Please follow the notes and instructions below
each chart when checking sensors.

Thermistor Sensor Testing Instructions
Use the resistance column to check the thermistor sensor while disconnected
from the controllers (not powered). Use the voltage column to
check sensors while connected to powered controllers. Read voltage
with meter set on DC volts. Place the “-”(minus) lead on GND terminal
and the “+”(plus) lead on the sensor input terminal being investigated.
If the voltage is above 5.08 VDC, then the sensor or wiring is “open.”
If the voltage is less than 0.05 VDC, the sensor or wiring is shorted.
