VAV/Zone Controller Overview
The OE326-23I-OR VAV/Zone Controller is designed for pres-
sure independent VAV Box and Zone Damper applications. It
is supplied with an integral Airfl ow Sensor and is mounted in a
plastic enclosure.
The OE326-23D-OR VAV/Zone Controller is designed for pres-
sure dependent VAV Box and Zone Damper applications and is
mounted in a plastic enclosure.
The OE326-23I-OR and OE326-23D-OR VAV/Zone Controllers
utilize terminal block connections for wiring. The 24 VAC power
is supplied from a transformer (by others) wired to the VAV/Zone
Controller using standard stranded wire and 2 position terminal
blocks. The communications wiring is connected between the
other VAV/Zone Controllers, CommLink 5, MiniLink PD5,
HVAC unit controller or other controllers on the local loop by
using 2 conductor 18 gauge twisted pair with shield wire which
is connected to the VAV/Zone Controllers via a standard 3 posi-
tion terminal block.
Both VAV/Zone Controllers are designed for use with an OE282-
01 Zone Damper Actuator. The VAV/Zone Controller connects
to the actuator via the modular cable that is included with the
actuator.
The VAV/Zone Controller can use a Standard Room Temperature
Sensor wired to the provided 3 position terminal block or an
E-BUS Digital Room Sensor connected via the integral E-BUS
cable connector or to the provided 4 position terminal block. The
VAV/Zone Controller also has a 2 position terminal block for
wiring a Discharge Temperature Sensor, if desired.
A relay output on the VAV/Zone Controller provides for one stage
of electric heat or an On/Off Hot Water Valve if the controlled
terminal unit is not a fan terminal unit.
An optional Expansion Module is available for applications us-
ing fan terminals and/or more than 1 stage of electric heat, SCR
electric heat, or modulating HW heat. The Expansion Module
connects to the VAV/Zone Controller by means of a prefabricated
E-BUS cable.

Mounting and Installation
Mounting & Installation
If you purchased the Round Zone Damper or Rectangular Zone
Damper Kits from WattMaster, the controller and actuator are
factory mounted and wired in the damper control enclosure. If
your VAV/Zone Controllers are pressure independent, an airfl ow
probe and pressure sensor will also be factory mounted and wired.
Most terminal unit manufacturers will off er the option of fac-
tory mounting the Orion controls in their terminal units for an
additional charge. An installation worksheet and instructions
are available for the Orion VAV/Zone Controller package which
can be shipped with the VAV/Zone control(s) to the terminal
unit manufacturer to simplify factory mounting and wiring of
the controller.
VAV/Zone Controller Package
NOTE: The VAV/Zone Controller defaults to Direct Acting,
which means that when looking at the damper shaft,
the damper rotates clockwise to open. If the damper
on the terminal unit is not installed for clockwise to
open operation, the WattMaster Zone Controller can
be confi gured for counterclockwise to open opera-
tion via the operator interface or through the Prism
software. It must be changed prior to system start-up
for the designated units for the zone damper to func-
tion properly. See your operator interface or Prism
manual for further information on reconfi guring for
reverse acting operation. Installation is the same as
for clockwise-to-open units except all references to
clockwise will now be counter-clockwise direction.
1. The terminal unit damper (by others) should be installed so the
damper shaft turns in a clockwise direction to open the damper.
This is the software default for the VAV/Zone Controller Pack-
age. If this is not possible, the Controller can be re-confi gured for
counter-clockwise-to-open operation using the Prism software.
See the note above for details. All installation instructions are
based on the clockwise-to-open default. Check the damper for
proper rotation and mark the end of the damper shaft to indicate
open and closed positions.
2. Loosen the (2) shaft mounting bracket nuts on the ends of the
damper actuator’s shaft mounting U-bolt and slide damper actua-
tor assembly over the terminal unit damper shaft. The actuator
may have to be rotated from position shown depending on the
terminal unit’s available mounting area and damper shaft loca-
tion and whether this is a left or right hand installation. Hand
tighten the U-bolt nuts until the damper shaft is loosely secured
to the shaft.
Space Temperature Sensors
The Space Temperature Sensors should be mounted in the space
served by the equipment the sensor is connected or hard wired
to. All Space Sensors should be mounted approximately 5 feet
above the fl oor and in an area that does not experience direct
sunlight or drafts in order to get accurate readings. Cabling or
wiring should be routed so the wire or cable is protected from
being pinched or punctured by building fasteners or materials.
Discharge Temperature Sensors
These sensors should be mounted in the supply air duct of the
equipment. The Discharge Temperature Sensor should be mount-
ed at least 10 feet away from any Heating or Cooling source and
be mounted 3 duct diameters from any elbow.
Cabling or wiring should be routed so the wire or cable is pro-
tected from being pinched or punctured by building fasteners
or materials.
NOTE: If this is a stand-alone damper, this sensor would be
mounted upstream of the damper to act as a Supply
Air Sensor.
3. After positioning the damper actuator over the damper shaft,
secure the damper actuator to the controller enclosure base using
the supplied L-bracket and 2 screws.
4 Turn the damper blade to its fully closed position. With the
manual override clutch button depressed, rotate the actuator
clamp to within approximately 1/16 inch to ⅛ inch distance be-
tween the actuator stop and the clamp, depending on the damper
seal design. Tighten the (2) shaft mounting bracket nuts on the
ends of the damper actuator’s shaft mounting U-bolt with an 8
mm wrench to 3-5 ft-lb of torque. On dampers with edge seals,
the actuator will compress the damper blade seal when reaching
the end position. Adjust the end stops, if required. Attach the
actuator cable between the actuator and controller.

INSTALLATION & WIRING

Important Wiring Considerations
General
Correct wiring of the VAV/Zone Controller is the most important
factor in the overall success of the controller installation process.
The VAV/Zone Controller wiring has been simplifi ed by the use
of modular connectors and prefabricated modular cables.
Voltage and Environment Requirements
The VAV/Zone Controller and expansion modules must be
connected to a 24 VAC power source of the proper size for the
calculated VA load requirements. All transformer sizing should
be based on the VA rating listed in Table 1.

WARNING: When using a single transformer to power more
than one controller or expansion module, the
correct polarity must always be maintained be-
tween the boards. Failure to observe correct
polarity will result in damage to the VAV/Zone
Controller, actuator, and expansion module.
Important Wiring Considerations
Please carefully read and apply the following information when
wiring the VAV/Zone Controller Package. See Figure 10, page
20 for VAV/Zone Controller Package wiring and connections.
See Figure 9, page 17 for connecting and wiring multiple VAV/
Zone Controller Packages in a system.
1. Size and wire the transformer to be used for powering the
Non-Modular VAV/Zone Controller Package(s) per the
instructions. Failure to size the transformer and/or wire the
Non-Modular VAV/Zone Controller Package(s) correctly
may cause the VAV/Zone Controller Package to operate
erratically or not at all. See Figure 8, page 16 for wiring
and transformer sizing information.
2. All wiring is to be in accordance with local and national
electrical codes and specifi cations.
3. All 24 VAC wiring must be connected so that all ground
wires remain common. Failure to follow this procedure
can result in damage to the controller and connected
devices.
4. Minimum wire size for 24 VAC wiring should be
18-gauge.
5. Minimum wire size for all sensors should be 24-gauge.
Some sensors require 2-conductor wire and some require
3-or 4-conductor wire.
6. Minimum wire size for 24 VAC thermostat wiring should
be 22 gauge.
7. Be sure that all wiring connections are properly inserted
and tightened into the terminal blocks. Do not allow
wire strands to stick out and touch adjoining terminals
which could potentially cause a short circuit.
8. Do not pry on the connectors when connecting or
disconnecting the modular cables. Be sure to push in on
the connector release clip and then pull straight up.
9. When communication wiring is to be used to intercon-
nect VAV/Zone Controllers together or to connect to other
communication devices, all wiring must be plenum-
rated, minimum 18-gauge, 2-conductor, twisted pair with
shield. WattMaster can supply communication wire that
meets this specifi cation and is color coded for the
network or local loop. Please consult your WattMaster
distributor for information. If desired, Belden #82760 or
equivalent wire may also be used.
10. Before applying power to the VAV/Zone Controller,
be sure to recheck all wiring connections and
terminations thoroughly.
14 VAV/Zone Controller Package
INSTALLATION & WIRING

Wiring Checks
One of the most important checks to make before powering up
the system for the fi rst time is to confi rm proper voltage and
transformer sizing. Each VAV/Zone Controller Package requires
6 VA of power delivered to it at 24 VAC. See pages 20-21 of this
manual for complete wiring and transformer sizing information
for the VAV/Zone Controller.
Check all modular connectors to be sure they are completely
pushed and locked into their mating connectors. Confi rm that all
sensors required for your system are mounted in the appropriate
location and that the modular cables are plugged into the correct
connectors on the VAV/Zone Controller. Check the actuator cable
and be sure it is plugged in and secured to the modular connec-
tor on the actuator and the VAV/Zone Controller circuit board
modular connector. If using a Standard Room Sensor or terminal
connection for an E-BUS Digital Room Sensor, check to make
sure the wiring is correct. See Figure 10, page 20 in this manual
for wiring details. If attaching an E-BUS Sensor with an E-BUS
cable, make sure the E-BUS connector is connected to one end
of the E-BUS sensor cable and the other end is connected to the
E-BUS sensor connector on the VAV/Zone Controller. Be sure
any VAV/Zone Controller Expansion Modules connected to the
VAV/Zone Controller are also correctly wired per the VAV/Zone
Controller Expansion Module wiring instructions on pages 20
through 23 of this manual.
After all the above wiring checks are complete, apply power to
the transformer(s) that is connected to the VAV/Zone Controller.
Powering Up
When the Controller and Modules are fi rst powered up, the
POWER LED should light up and stay on continuously. If it does
not light up, check to be sure that you have 24 VAC connected to
the controller, that the wiring connections are tight, and that they
are wired for the correct polarity. The 24 VAC power must be
connected so that all ground wires remain common. If after mak-
ing all these checks, the POWER LED does not light up, please
contact WattMaster Controls Technical Support for assistance.
Power Wiring
One of the most important checks to make before powering up
the system for the fi rst time is to confi rm proper voltage and
transformer sizing for each controller. Each VAV/Zone Control-
ler requires 6 VA of power delivered to it at 24 VAC. You may
use separate transformers for each device (preferred) or power
several devices from a common transformer. If several devices
are to be powered from a single transformer, correct polarity
must be followed.
WARNING: Observe Polarity! All boards must be wired with
GND-to-GND and 24 VAC-to-24 VAC. Failure to
observe polarity will result in damage to one or
more of the boards.
Check all wiring leads at the terminal block for tightness. Be sure
that wire strands do not stick out and touch adjacent terminals.
Confi rm that all sensors required for your system are mounted
in the appropriate location and wired into the correct terminals
on the VAV/Zone Controller.
After all the above wiring checks are complete, apply power to
the VAV/Zone Controller.

120 / 24VAC
Some installers like to use one large 24 VAC transformer to power several devices. This is allowable as long as polarity is maintained to each device
on the transformer circuit.
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 24 VAC power to the devices.
Following is a typical example to help the installer to correctly evaluate transformer and wiring designs.
Each GPC-XP Controller requires 8 VA @ 24VAC power. In the examples below we have a total of 8 GPC-XP Controllers.
8 GPC-XP Controllers @ 8 VA each................ 8 x 8 VA = 64 VA.
The above calculation determines that our transformer will need to be sized for a minimum of 64 VA 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..
2 (Volts total allowable voltage drop)
= 57.80
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).
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.
0.0346
feet
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.

Figure 9: VAV/Zone Controllers Communication & Power Wiring Diagram
17
VAV/Zone Controller Package
INSTALLATION & WIRING

18 VAV/Zone Controller Package
INSTALLATION & WIRING
VAV/Zone Controller Inputs
Analog Space Sensor or Digital Space Sensor
A Standard Room Temperature Sensor that hard wires to the
Space Sensor wiring terminals on the VAV/Zone Controller is
used when an analog sensor is desired. When an E-BUS Digital
Room Temperature Sensor is desired, it can connect to the Digital
Space Sensor wire terminals on the VAV/Zone Controller or it can
be connected to the E-BUS connector on the VAV/Zone Control-
ler using an E-BUS pre-fabricated cable of the desired length.
Discharge Temperature Sensor
This sensor can be used for monitoring the discharge air tempera-
ture of the terminal unit, round damper or rectangular damper
used with the VAV/Zone Controller. The sensor is typically used
when the terminal unit has reheat installed so the true temperature
of the air being supplied to the space can be monitored. It should
be mounted in the discharge duct downstream of the terminal unit
where the VAV/Zone Controller is installed.
NOTE: If this is a stand-alone damper, this sensor would be
mounted upstream of the damper to act as a Supply
Air Sensor.
Occupied Switch
This input is used when you have a motion switch or window
switch to determine room occupancy and allows for setback of
the heating or cooling during occupied periods.
Window Open Detection Mode
If the “Window Open Detection” button is checked, and the “Oc-
cupied Switch” contacts (located on the VAV/Zone Controller)
are open, the VAV/Zone controller will control to the Unoccupied
Cooling and Heating Setpoints and the Damper will completely
close. When the contacts are shorted, the unit will control to the
Occupied Cooling and Heating Setpoints. If the “Reverse Contact
Polarity” button is checked, then the unit controls to the Unoc-
cupied Cooling and Heating setpoints when the Occupied Switch
contacts are shorted, and control to the Occupied Cooling and
Heating Setpoints when the contacts are open.
Motion Sensor Occupancy Detection
This operation only occurs in the scheduled Occupied Mode.
If the Motion Sensor Occupancy Detection button is checked,
then the Occupancy Detection Time and Occupancy Duration
Timeout setpoints are used to determine the cooling and heating
setpoints of the VAV/Zone controller. A motion sensor is con-
nected to the Occupied Switch contacts (located on the VAV/
Zone Controller) and when motion is detected (contacts shorted
together) for the Occupancy Detection Time period, the control-
ler will display “Occupied Mode” and control to the Occupied
Cooling and Heating setpoints. If no motion is detected for a
period longer than the Occupancy Duration Timeout setpoint, (the
contacts will open) the controller will display “Occupied Room
Empty” and the controller will go to the Occupancy Cooling and
Heating Setback temperatures, until motion is detected again. If
the “Reverse Contact Polarity” button is checked, then the unit
controls the opposite. When no motion is detected (contacts
shorted) the controller will display “Occupied Room Empty” and
unit will control to the Occupancy Cooling and Heating Setback
temperatures, until motion is detected. When motion is detected
(contacts open) for the Occupancy Detection Time period, the
controller will display “Occupied Mode” and control to the Oc-
cupied Cooling and Heating setpoints.
Airflow Sensor
If the OE326-23I-OR Pressure Independent VAV/Zone Control-
ler is being used, the terminal unit’s pressure pick-up tube must
be connected with FRP tubing to the barb fi ttings on the side of
the VAV/Zone Controller. No wiring connections are required as
the pressure sensor is integral to the VAV/Zone Controller. This
pressure sensor input is used for CFM (airfl ow) calculations.
VAV/Zone Controller Outputs
Auxiliary Reheat Relay
This relay has a dry contact on the VAV/Zone Controller and can
be confi gured for Auxiliary Heat or Box Re-heat. Box Re-heat
is used when you only need 1 stage of electric heat or On/Off
Hot Water Valve. Auxiliary Heat is selected when you are using
Baseboard or some other Heating Source. Use this relay if the
controlled terminal unit is not a fan terminal unit. When you are
using a fan terminal unit or have more than 1 stage of electric
heat, SCR electric heat, or modulating HW heat, the OE325-03
VAV/Zone Controller Expansion Module must be used.
Confi gure the relay for Auxiliary Heat if the heat being controlled
by the controller is baseboard type heat or any other type heat
that does not require airfl ow through box. The relay will be
energized whenever the Space Temperature drops 0.5° below
the Auxiliary Heat Setpoint and the damper will remain in the
position determined by the mode of operation.
If the relay is confi gured for Box Reheat, then the relay will be
energized whenever the Space Temperature drops below the Oc-
cupied Heating Setpoint and the damper will go to the Minimum
Damper During Box Heating Mode Setpoint. The stages of box
reheat will need to be set to 1.

VAV/Zone Controller Package
INSTALLATION & WIRING
VAV/Zone Controller Expansion
Module Outputs
As previously stated, when you are using a fan terminal unit or
have more than 1 stage of electric heat, have SCR electric heat, or
have modulating HW heat, the OE325-03 VAV/Zone Controller
Expansion Module is required.
Binary Input - Proof of Flow
This input is for an airfl ow Proving Switch. It is only an option
with Stand-Alone damper applications using electric reheat.
Relay #1 - Fan Enable
This relay is used for energizing the Fan on Series or Parallel
Fan Terminal units.
Relay #2 - Heating Stage 1
If you have at least 1 stage of Heat, this relay is used to energize
the 1st stage of terminal unit Heat. This Heating Stage can either
be used with Electric Heat or On/Off Hot Water Valve control.
Relay #3 - Heating Stage 2
If you have 2 stages of Electric Heat, this relay controls the 2nd
stage of Electric Heat.
Relay #4 - Heating Stage 3
If you have 3 stages of Electric Heat, this relay controls the 3rd
stage of Electric Heat.
Analog Output
If you are using SCR Electric Heat or a modulating Hot Water
Valve or modulating Steam Valve for Heating, this output can
supply a 0-10 VDC signal for proportional control of the Valve
or SCR Electric Heater.
VAV/Zone Controller Expansion Module Inputs and Outputs
Other Connections
E-BUS Connectors
The EBC E-BUS modular connectors are used to connect the
optional OE325-03 VAV/Zone Controller Expansion Module to
the VAV/Zone Controller. The expansion module is only required
when staged electric heat (more than 1 stage), SCR electric heat,
modulating HW heat, and/or fan terminal control is required.
The E-BUS connector can also be used to connect an E-BUS
Digital Room Temperature Sensor to the VAV/Zone Controller
if desired.
Actuator Modular Connector
This modular connector is used to connect a modular cable from
the VAV/Zone Controller to a damper actuator.

This three position terminal block is used for connecting the
communications wiring between each VAV/Zone Controller and/
or to the MiniLink, HVAC Unit Controller, or other installed
controller on the local communications loop. Communications
wiring should be 18 gauge minimum 2 conductor twisted pair
with shield Belden #82760 or its equivalent.
24 VAC Power Terminal Block
This two position terminal block is used to wire the 24 Volt
power to the VAV/Zone Controller Packages. If desired, a single
transformer can be used to power multiple VAV/Zone Control-
ler Packages together, or a separate transformer can be used for
each controller.
WARNING: If multiple controllers are to be wired to the
same transformer, polarity must be observed or
damage to the controller will result.
