Troubleshooting
Symptom
Action
No display on master
controller / thermostat
or
Dim display on master
controller / thermostat
Verify power module wiring.
Verify cables are correct.
RJ-12, 6-pin, straight through pinout from power module to first T

SQ diffuser or between master T

SQ units
and RJ-45, 8-pin, straight through pinout from T
3
SQ diffuser to master controller / thermostat.
Verify cable continuity with a cable tester.
Note: The Power Module has integral circuit protection that protects it from shorts in the RJ-12 and RJ-45 cabling by
shutting down the Power Module. During this process, the Power Module may heat up enough that the component
coatings emit a smell much like burnt electronics, but the transformer is NOT damaged. Replace the bad cable and
cycle power to the Power Module.
Control disk will not move
Verify that control disk cable has been properly inserted through conduit and plugged into wiring interface box on
backpan.
Verify that master units is properly connected with RJ-45 to master controller / thermostat or verify that drone units are
properly connected with RJ-45 to a master unit.
Occupant uncomfortable,
control disc closed
Adjust setpoints on master controller / thermostat.
Check supply air temperature by pushing and holding top arrow for 5 seconds.
If supply air is warmer than setpoint and setpoint is below zone temperature, damper will close to reduce
supply air volume into space.
If supply air is cooler than setpoint and setpoint is above zone temperature, damper will close to reduce
supply air volume into space.
Control disk will not go to
full closed
Adjust brass nuts at the top of the actuator shaft to desired minimum position.
Supply air temperature
reading is incorrect
Verify that the supply air temperature sensor is securely connected on all master units – thermostat display will show
“00” if the supply air temperature sensor is not connected.
Verify that the supply air temperature sensor has been disconnected from all drone units – thermostat display will read
incorrectly if drone units has a supply air temperature sensor.
Unit is operating in reverse
(closing when it should be
opening, etc.)
Follow steps in “Occupant uncomfortable” above to ensure proper setpoints and verify supply air temperature.
Follow steps in “Supply air temperature reading is incorrect” above to ensure supply air temperature is correct.
