Systems Overview
General Information
The WattMaster VAV system components can be configured into different types of systems depending on the type and number of controllers required. It is a good idea to become familiar with the 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
Two different system configurations are available depending on the type
and number of controllers that you have on your system.
1. Networked Single Loop
(See Pages 6 Through 8 For Connection Diagrams)
2. Networked Multiple Loop
(See Pages 9 Through 11 For Connection Diagrams)
System Type Definitions
Networked Single Loop
The Networked Single Loop system, as its name implies, consists of a
single communications loop. The system can consist of the following
controllers and devices.
1. A single WMVAV controller used as a VAV controller and
it’s associated VAVBOXcontrollers. Other WMVAV
controllers used for constant volume units and/or and Addon Devices may also be connected as long as the total of all
controllers on the loop does not exceed 59. Only one VAV
controller with it’s VAVBOX controllers can be installed
per loop. If more than one VAV controller with VAVBOX
controllers is required, you must have a separate loop for
each.
This system requires one CommLink communications interface and
one MiniLink Polling Device. Programming and status monitoring are
accomplished by the following methods.
1. By using an operators interface. This can be either a
Modular System Manager, a Modular Service Tool or both
devices. The System Manager or Modular Service Tool
can connect to any controller on the local loop.
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. The PC connects to the CommLink
via a supplied cable.
2. A single WMVAV controller used as a VAV controller and
its associated VAVBOX controllers. Other WMVAV
controllers used for constant volume units and/or and Addon Devices may also be connected as long as the total of all
controllers on the loop does not exceed 59. Only one VAV
controller with its VAVBOX controllers can be installed
per local loop.
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 and also provides alarming and trend logging
capabilities.
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.
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 can
connect to any controller on any “Local Loop” on the
entire 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. The PC connects to the CommLink
via a supplied cable.
Network Communications Devices
MiniLink Polling Device
1. This device is required for all Networked Single loop
systems.
2. One of these device is required on each local loop of all
Networked Multiple Loop systems
CommLink
1. One CommLink is required on all Networked Single Loop
or Multiple Loop Systems
2. Up to 60 local loops can be connected to the CommLink
Installation Procedures
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 local loops can consist of the
following controllers and devices.
1. A series of WMVAV controllers for constant volume units
and/or Add-on devices without any VAVBOX controllers.
Up to 59 controllers may be connected on the loop in this
manner.
The installation procedures that follow are based on recommended methods of wiring connection and controller installation. Installation procedures vary depending on the which Networked system you are installing. The system you are installing could be “Networked Single Loop”
or a “Networked Multiple Loop” system. The Networked Systems
also have installation variations based on the type of components you
are installing for that system. The following information explains the
procedures for all of these systems. Please find the system and components that closely match your system and follow the outlined procedures.
Component & System Wiring12
Networked Single Loop Systems
See the “Networked System - Single Loop Wiring” on pages 6 through
8 of this manual for detailed wiring information. Also see page 16 for
wire and transformer sizing information. You should review these diagrams before attempting connections or powering up the controller or
interface devices.
1. Connect all WMVAV or Add-on Device controllers in a
daisy chain or star ring format by connecting from each
controller’s communication terminal block to the next using
18 gauge, 2 conductor shielded cable. Install a separate 24
VAC, transformer for each controller and wire from each
controller’s power terminal block to its transformer using
18 gauge minimum, 2 wire cable for power. See Wire and
Transformer Sizing section on page 16 for detailed
transformer and wire sizing information. Observe polarity
on all board power wiring. Install a separate 24 VAC, 6 VA
minimum, transformer for each VAVBOX controller on the
loop and wire from each controller’s power terminal block
to its transformer using 18 gauge minimum, 2 wire cable.
Observe polarity on all boards! As an alternative, a single
transformer that connects to all VAVBOX controllers may
also be used. It must be sized to handle the minimum load
of 6 VA per VAVBOX controller connected to it. When
using this method, the polarity of all wiring between the
transformer and the VAVBOX controllers is extremely
critical and must be maintained to prevent damage to
all boards connected! See the wire and transformer sizing
information on page 16 of this manual for complete
wire and transformer sizing information.
Warning: If polarity between controllers is not maintained,
severe damage to the controllers may result.
WattMaster recommends using a separate transformer
for each controller in order to eliminate the potential
for damaging controllers due to incorrect polarity.
2. Using 18 gauge 2 conductor shielded cable, connect from
the WMVAV controller’s 3 wire communications
connector to the MiniLink PD’s 3 wire communications
connector marked “Local Loop”.
3. Connect 2 conductor shielded cable from the
MiniLink PD’s 3 wire communications terminal blocks
labeled “Network Loop” to the CommLink’s 3 wire
communications terminal block located on the back of the
CommLink. Find the 110 VAC/24 VAC power supply
furnished with the CommLink and connect the 2 stripped
wire leads to the 24 VAC terminals on the back of the
CommLink. The CommLink’s internal jumper must be set
to “Multiple” for all WattMaster VAV systems. See page 45
of this manual for complete CommLink wiring and jumper
setting information. After determining all wiring and
jumper settings are correct, connect the power supply plugin transformer to a 110 V receptacle.
4. Install a 24 VAC, 6 VA minimum, transformer for the
MiniLink PD and wire it to the 24 VAC power terminal
block on the MiniLink PD using 18 gauge minimum, 2
wire cable. See page 46 of this manual for complete
MiniLink PD wiring diagrams and instructions.
5. When the Modular Service Tool is to be used for
programming and monitoring of the controllers it can be
connected to the WMVAV controllers using the supplied
cable with DIN connectors on both ends. The DIN
connector on the WMVAV controller is located near the
communications terminals. To connect the Modular Service
Tool to a VAVBOX controller first unplug the 3 wire
communication terminal block from the VAVBOX
controller. Connect the DIN to terminal adapter terminal
end to the communication terminals block socket on the
VAVBOX controller then connect the DIN connector side
of the adapter to the Modular Service Tool cable DIN
connector. See page 44 of this manual for complete
Modular Service Tool connection diagrams and
instructions.
6. The Modular System Manager comes supplied with a 12
foot modular cable pigtail with a modular connector on one
end and stripped wires on the other. Plug the modular
connector end into the System Manager modular connector.
Run 18 gauge, 2 conductor shielded cable for
communications from the MiniLink PD or any controller
on the local loop by connecting one end of the controller’s
or MiniLink PD’s 3 wire “Local Loop” communications
terminal block to a junction box located within 12 feet of
the System Manager. Run 18 gauge, 2 wire, power wires
supplied by a separate 24 VAC, 6 VA minimum transformer
into the junction box. Splice the stripped modular cable
ends from the System Manager to the communications and
power wire inside of the junction box using solid
connections made with wire nuts or butt-splice connectors.
See Modular System Manager wiring on pages 42 and 43
of this manual for wiring color coding and complete wiring
instructions. The Modular System Manager MUST always
be connected on the “Local Loop”, never the “Network
Loop”.
Networked Multiple Loop Systems
See the “Networked System - Multiple Loop Wiring” on pages 9 through
11 of this manual for detailed wiring diagrams. Also see page 16 for
wire and transformer sizing information. You should review these diagrams before attempting connections or powering up the controller or
interface devices.
Loop(s) with WMVAV Controllers without VAVBOX Controllers
1. For each local loop on the system, connect all controllers in
a daisy chain or star ring format by connecting from each
controllers communication terminal block to the next using
18 gauge, 2 conductor shielded cable. Install a separate 24
VAC, 8 VA minimum, transformer for each controller and
wire from each controller’s power terminal block to its
transformer using 18 gauge minimum, 2 wire cable for
power. Observe polarity on all boards.
2. Select one of the local loops and connect 2 conductor
shielded cable from one of its WMVAV controller’s 3 wire

jumper setting information. After determining all wiring
and jumper settings are correct, connect the power supply
plug-in transformer to a 110 V receptacle.
4. Connect 2 conductor shielded cable for network
communications between each MiniLink PD on the system
including the one that was just connected to the
CommLink. This is accomplished by connecting between
each MiniLink PD’s 3 wire communications terminal block
labeled “Network Loop” and the next MiniLink PD’s
communications terminal block labeled “Network Loop”.
Install a 24 VAC, 6 VA minimum, transformer for each of
the MiniLink PDs on the system and wire each transformer
to the 24 VAC power terminal block for its respective
MiniLink PD using 18 gauge minimum, 2 wire cable. See
page 46 of this manual for complete MiniLink PD wiring
diagrams and instructions.
5. When the Modular Service Tool is to be used for
programming and monitoring of the controllers it can be
connected to the WMVAV controllers using the supplied
cable with DIN connectors on both ends. The DIN
connector on the WMVAV controller is located near the
communications terminals. See page 44 of this manual for
complete Modular Service Tool connection diagrams and
instructions.
6. The Modular System Manager comes supplied with a 12
foot modular cable pigtail with a modular connector on one
end and stripped wires on the other. Plug the modular
connector end into the System Manager modular connector.
Run 18 gauge, 2 conductor shielded cable for
communications from the MiniLink PD or any controller
on the local loop by connecting one end the controller’s or
MiniLink PD’s 3 wire “Local Loop” communications
terminal block to a junction box located within 12 feet of
the System Manager. Run 18 gauge, 2 wire, power wires
supplied by a separate 24 VAC, 6 VA minimum transformer
into the junction box. Splice the stripped modular cable
ends from the System Manager to the communications and
power wire inside of the junction box using solid
connections made with wire nuts or butt-splice connectors.
See Modular System Manager wiring on pages 42 and 43
of this manual for wiring color coding and complete wiring
instructions. The Modular System Manager MUST always
be connected on the “Local Loop”, never the “Network
Loop”.
Loop(s) with WMVAV and VAVBOX Controllers
1. Select one of the local loops on your system. Connect all
WMVAV or Add-on Device controllers in a daisy chain or
star ring format by connecting from each controller’s
communication terminal block to the next using 18 gauge,
2 conductor shielded cable. Install a separate 24 VAC,
transformer for each controller and wire from each
controller’s power terminal block to its transformer using
18 gauge minimum, 2 wire cable for power. See Wire and
Transformer Sizing section on page 16 for detailed
transformer and wire sizing information. Observe polarity
on all board power wiring. Install a separate 24 VAC, 8 VA
minimum, transformer for each VAVBOX controller on the
loop and wire from each controller’s power terminal block
to it’s transformer using 18 gauge minimum, 2 wire cable.
Observe polarity on all boards! As an alternative, a single
transformer that connects to all VAVBOX controllers may
also be used. It must be sized to handle the minimum load
of 6 VA per VAVBOX controller connected to it. When
using this method, the polarity of all wiring between the
transformer and the VAVBOX controllers is extremely
critical and must be maintained to prevent damage to
all boards connected! See the wire and transformer sizing
information on page 16 of this manual for complete wire
and transformer sizing information. Repeat this procedure
for each loop with VAVBOX controllers on your system.
Warning: If polarity between controllers is not maintained,
severe damage to the controllers may result.
WattMaster recommends using a separate transformer
for each controller in order to eliminate the potential
for damaging controllers due to incorrect polarity.
2. For each local loop on the system do the following. Using
18 gauge 2 conductor shielded cable, connect from
one of the WMVAV controller’s on the loop, 3 wire
communications connector to that loop’s MiniLink PD 3
wire communications terminal block marked “Local Loop”.
3. To install the CommLink, connect 2 conductor shielded
cable from one of the system’s MiniLink PD’s 3 wire
communications terminal blocks labeled “Network Loop”
to the CommLink’s 3 wire communications terminal block
located on the back of the CommLink. Find the 110 VAC/
24 VAC power supply furnished with the CommLink and
connect the 2 stripped wire leads to the 24 VAC terminals
on the back of the CommLink. The CommLink’s internal
jumper must be set to “Multiple” for all WattMaster VAV
systems. See page 45 of this manual for complete
CommLink wiring and jumper setting information. After
determining all wiring and jumper settings are correct,
connect the power supply plug-in transformer to a 110 V
receptacle.
4. The following procedure must be performed for each
MiniLink PD on your system. Install a 24 VAC, 6 VA
minimum, transformer for theMiniLink PD and wire it to
the 24 VAC power terminal block on the MiniLink PD
using 18 gauge minimum, 2 wire cable. See page 46 of this
manual for complete MiniLink PD wiring diagrams and
instructions. Be sure that all MiniLink PDs on the entire
system are wired as required.
Component & System Wiring14
5. When the Modular Service Tool is to be used for
programming and monitoring of the controllers it can be
connected to the WMVAV controllers using the supplied
cable with DIN connectors on both ends. The DIN
connector on the WMVAV controller is located near the
communications terminals. To connect the Modular Service
Tool to a VAVBOX controller, first unplug the 3 wire
communication terminal block from the VAVBOX
controller. Connect the DIN to terminal adapter terminal
end to the communication terminals block socket on the
VAVBOX controller then connect the DIN connector side
of the adapter to the Modular Service Tool cable DIN

The following information is a brief overview of the procedures required to commission a typical WattMaster VAV System.
1. Address each MiniLink PD on the system with a unique
address from 1 to 60.
2. On a loop of WMVAV controllers and/or Add-on Devices,
without VAVBOX Controllers, address the controllers and
devices from 1 to 59.
3. On a loop which has VAVBOX controllers, address
the VAVBOX controllers from 1 to 58. Address the
WMVAV controller serving the VAVBOX controllers as
address 59. Address all other controllers with addresses not
already used by other controllers on the loop.
4. Always apply power to the system in the following order.
WMVAV controllers or Add-on Devices, MiniLink PD(s),
CommLink, VAVBOX controllers (if used).
5. After powering up verify diagnostics LED indicator for
proper operation of all controllers. See the technical guide
for each specific controller for detailed information on the
location of its diagnostic LED, and each controller’s
start-up sequence.
6. If a computer is used, install the Prism computer front end
software on it and connect it to the CommLink to access
all of the controllers on the entire system for programming.
7. If a computer is not used, and if a Modular System Manger
is not already connected on the local loop, connect a
Modular Service Tool to one of the controllers to perform
programming of all controllers on the entire system.

Transformer & Wire Sizing
24VAC Power - Transformer & Wire Sizing Considerations For VAVBOX Controllers
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 VAVBOX Controller requires 6 VA @ 24VAC power. In the examples below we have a total of 10 VAV Controllers.
10 VAVBOX Controllers @ 6VA each................ 10 x 6VA =60VA.
The above calculation determines that our transformer will need to be sized for a minimum of 60VA if we are to use one transformer to power all the
controllers. We will use a 75 VA transformer, as this is a readily available size that meets our VA load requirements.
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 10 controllers to be installed.
0.00054 (Voltage drop per foot for 18 gauge wire) x 60VA controller load = Volts/Ft.
WattMaster VAVBOX 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
thana2Voltdrop at the farthest controller from the transformer..
Parallel circuiting of the wiring instead of wiring all 10 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 and that the polarity is maintained to all controllers connected to the
transformer.
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

Space Temperature Sensor Information
The Space Temperature Sensor is typically used for constant volume HVAC
unit applications controlling one zone. The Space Temperature Sensor is a
10K Type III thermistor sensor. The Space Temperature Sensor should be
mounted approximately 5 ft. above the floor in the space that is to be
controlled. The Space Temperature Sensor is available in a sensor only,
sensor with override button, sensor with slide adjust and sensor with slide
adjust and override configurations. If the Space Temperature Sensor with
Slide Adjust option is to be used, the Fan Proof of Flow Switch cannot be
used.
