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.

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

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

The Supply and Return Air Temperature Sensors must be wired as shown in the
illustration below for proper operation. The Supply and Return Air Temperature
Sensors are 10K Type III thermistor sensors. The Supply Air Temperature Sensor
should be mounted in the unit discharge plenum or in the supply air duct. The Return
Air Temperature Sensor should be mounted in the return air duct. If the system has a
bypass damper installed, be sure the return air sensor is located upstream of the
bypass duct connection.

Outside Air Sensor Wiring
Caution:
Be sure to mount the Outside Air Sensor in an area that is not exposed to direct sunlight. A
shaded area under the eve of the building or under the HVAC unit rainhood is normally a good
location. If sensor is not located as specified, erroneous outside air temperature readings will
result. Unused conduit opening(s) must have closure plugs installed and must be coated with a
sealing compound to provide raintight seal. Water can damage sensor!

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.

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.
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.
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.
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 chipbe installed with Pin 1 in the correct
MUST
location. Installing the chip “backwards” will in most
cases destroy the device when power is reapplied.
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.
Be certain thatpins are lined up in the socket
ALL
before pressing the chip in. Failure to properly line
up the pins will result in damage to the chip.
This is acommon error -
VERYBE 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.
