Installation, Operation & Maintenance of the T

SQ Analog

VAV Diffuser

Step 1

The units should be shipped assembled except for the backpan. The thermal T

SQ is shipped with

additional packaging to protect the actuator assembly. Remove all packaging from the components.

If the unit is not assembled, follow the steps below before proceeding (see Figure 1):

1. Insert the control disc guide into the control disc.

2. Screw the bottom of the actuator / control disc assembly into the mounting channel.

Place the back pan into ceiling grid. Connect duct work to back

pan. Insert the supply air temperature sensor into the supply

duct. If the unit has an optional inlet heater, the supply air

sensor must be positioned above the heater in the supply duct.

Set minimum airflow by adjusting

the brass nuts at the top of the

actuator shaft. 0.5" down from the top of the shaft allows the

diffuser to go to the full closed position.

Installation is completed by lining up the hooks on the face

plaque assembly with the corresponding slot. Insert the RJ-45

cable on actuator / control disc assembly through wiring conduit.

The hooks are inserted and the face plaque assembly is rotated

clockwise, and lowered so that each hook is firmly in place. (See

Figure 2)

Plug the RJ-45 cable on actuator / control disc assembly into

any RJ-45 jack on the wiring interface box on the backpan.

Note: The T

SQ-1 diffuser is shipped as a dummy unit. Master and drone operation is

determined by the wiring – discussed in Step 3. Master and drone locations are not needed

at this point in installation.

T3SQ-1-IOM-2.0 Step 4 6-6-09 Wiring Instructions: T3SQ-1 diffusers are all shipped as dummy units. Determination of master and drone units is made through plug and play cable connections. One power module is required for every six (6) diffusers without electric reheat or every five (5) diffusers with electric reheat. (See Figure 3) Power module requires 120VAC line voltage input – hardwired by others. (See Figure 4) Master diffusers must be connected to a controller / thermostat.
PAGE 3
T3SQ-1-IOM-3.0 6-6-09 Master Controller / Thermostat Operation When power is supplied to the diffusers and the controller / thermostat, the controller / thermostat will drive the diffusers to full closed to calibrate the movement of the master and drone units. During this startup operation the controller / thermostat will display “ST”. The controller / thermostat normally displays room temperature. The Cool and Heat indicator lights show the mode of operation that the unit is in.

T3SQ-1-IOM-5.0 6-6-09 Troubleshooting (cont.) Symptom Action No Power Thermostat not operating properly Check main power supply to power pack. Check two power supplies not on same circuit. This will definitely be a problem if the two power supplies are driven from different phases. Check thermostat cable If cable fine check drone cable between drone board and master controller Replace with another wall thermostat Replace with another power supply.

T3SQ-1-IOM-6.0 6-6-09 Troubleshooting (cont.) Symptom Action Erratic driving Check if controller is in proportional band. The motor will start pulsing when room is 1°F from setpoint and the motor will only drive full time when the room 3°F away from setpoint. Check to see if only one master controller is connected to diffusers in the same control loop. Not driving open or close Check if controller is in proportional band.
