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.
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 VA V/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 VA V/Zone
controllers.
To form the Networked Multiple Loop System the following network devices are required.
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.
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.

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 T echnical 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 wiring.

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 V AC 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 V AC 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 3­wire “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 vary depending on the type of system you are installing. The sys­tem you are installing could be a “Stand Alone”, “Interconnected”, “Net­worked Single Loop” or “Networked Multiple Loop” system.

Transfor mer & W ir e Sizing - Devices Without Modular Connector s
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.
using a separate transformer for each device in order to eliminate the potential for damaging controllers due to incorrect polarity.
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 = 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..
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). 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.
Warning:
It is often necessary for the installer to calculate and weigh the cost and installation advantages and disadvantages of wire size,
If polarity is not maintained, severe damage to the devices may result. WattMaster Controls recommends

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:
6 Devices Maximum Per Branch Circuit
16 Devices At 6 VA = 96 VA Use 100 VA Transformer
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.

JOB NAME
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!
