Initial Setup
Mounting
To mount the SE-ZEC Controllers:
1. Ensure that you have the appropriate personal protective equipment (PPE), such as a hard hat, safety glasses,
steel toe boots, and gloves.
2. Disconnect power to the VAV unit.
3. Set the MS/TP address, and ensure the end of line (EOL) switch is set to off. Instructions on setting the VAV
address and EOL are in the sections below.
4. Place the SE-ZEC Controller in the proper mounting position on the actuator shaft so that the wiring connections
are easily accessible. Make sure the SE-ZEC Controller base is parallel to the VAV box (perpendicular to the
damper shaft). If needed, use a spacer to offset tipping of the SE-ZEC Controller caused by the shaft bushings.
5. Use the alignment marks to center the captive spacer to ensure sufficient movement in either direction.

full-closed to full-open positions without bindi ng.
13. Complete the mounting by rotating the damper to the full-open position.
Networking
Field Controller (FC) Bus
The field controller (FC) Bus terminal block is a blue, removable, 4-terminal plug that is keyed to only fit in to the boardmounted, gray FC Bus jack. Wire the removable FC Bus terminal block plugs on the SE-ZEC Controller and other FC Bus
controllers in a daisy-chain configuration usin g 3-wire twisted, shielded cable.
Fig. 3: FC Bus Connections
SE-ZEC Controller Address
SE-ZEC Controllers are master devices on BACnet MS/TP (SA or FC) Buses. Before operating field controllers on a Bus,
you must set a valid and unique device address for each controller on the Bus. You set a field controller’s device address
by setting the positions of the switches on the devise address DIP switch block at the top of the controller. Device
addresses 4-127 are the valid addresses for the SE-ZEC controller. SE-ZEC Controllers ship with all address switches set
to ON. Set a valid and unique device address on the field controller before applying power to the controller on the Bus.
The DIP switch block has eight switches numbered 128, 64, 32, 16, 8, 4, 2, and 1.
To set the device addresses on a ZEC field controller:
1. Set all of the switches on the field controller’s device address DIP switch block (128 through 1) to OFF.
2. Set one or more of the seven address switches from 64 to 1 to ON, so that the sum of the switch numbers set to ON
equals the intended device address. Set the highest number switch that is less than or equal to the intended device
address to ON. Then continue setting lower numbered switches until the total equals the intended address.
For example: If the intended device address is 21, set the switches so that 16 + 4 + 1 = 21.
a. Set switch 16 to ON
b. Set switch 4 to ON
c. Set switch 1 to ON
3. Set a unique and sequential device address for each of the field controllers connected on the FC Bus, starting with
device address 4. To ensure the best Bus performance, set sequential device address es with no gaps in the de vice

address range (4, 5, 6, and so on). The field controllers do not need to be physically connected on the Bus in their
numerical device address order.
4. Write each field controller’s device address on the white label below the DIP switch block on the controller’s cover.
End-of-line (EOL) Switch
The EOL switch must be set to ON for the two devices located at either end of each bus segment on an FC bus. The EOL
switches must be set to OFF for all other devices on the bus segment on an FC bus.
Optional Components
Sensor Actuator (SA) Bus
Factory or field supplied zone sensors are wired to the SA bus on the SE-ZEC Controller. The SA Bus is a brown,
removable 4-terminal plug that is keyed to only fit into the board mounted SA bus. Wire the removable SA bus terminal
block plugs on the SE-ZEC Controller and other field devices in a daisy-chain configuration using 4-wire, shielded cable.
Fig. 4: SA Bus Connections
Supply Air Temp. Sensor
Factory or field-supplied supply air temperature sensors can be used to measure the supply air temperature at the inlet of
the VAV box. The supply air temperature is wired between terminals ICOM3 and IN3 on the SE-ZEC Controller. The
sensor should be mounted in the inlet duct centered in the side of the ductwork. Avoid installing the sensor near an elbow,
take off or transition. Avoid blocking air to the primary airflow sensor.
Factory provided nickel (1k ohm) temperature sensors have 4” long probes and stainless steel mounting flanges with (2)
provided hex-head self-drilling mounting screws. Sensors come equipped with 10 ft. plenum rated cables with ¼” internal
thread insulated quick-connect terminations on leads. Install sensor by drilling a hole into the ductwork, inserting the
sensor, and securing with provided screws. The sensor tip should not touch any part of the ductwork.
With the supply air temperature sensor installed, the SE-ZEC controller will change its control sequence based on the
measured supply air temperature. When parameter Heating Limit Enable is TRUE the controller will not allow re-heat to
engage when the supply air temperature is greater than the value set in Heating Supply Air Limit.
Additionally, the controller will switch to warmup mode when warmup conditions are present. Warmup conditions are
present when the supply air temperature (SAT) sensor value exceeds the zone temperature (ZNT) sensor in unoccupied
mode or exceeds it by the Warmup Differential in occupied mode. While in Warmup mode the minimum flow will be set to
the Warmup Min Flow.

Discharge Air Temp. Sensor
Factory or field supplied discharge air temperature sensors can be used to measure the temperature of the air being
discharged from the VAV box. The discharge air temperature sensor is wired between terminals ICOM1 and IN1 on the
SE-ZEC controller. The sensor should be mounted a minimum of 36” from the discharge of the unit and be centered in the
side of the ductwork. Avoid installing the sensor near an elbow, take off, or transition.

sensor, and securing with provided screws. The sensor tip should not touch any part of the ductwork.
Occupancy Sensor
The SE-ZEC Controllers adjust the heating and cooling temperature setpoints, as well as the airflow setpoints based on
the zone occupancy. There are three different states of zone occupancy:
• Occupied Mode
o Uses Occupied Heating (68°F) and Occupied Cooling (72°F) temperature setpoints as well as Occupi
eating and Occupied Cooling Airflow setpoints

o For Series Fan Powered Terminals the Fan is always on
