Troubleshooting
Table 37. Condensate pump does not energize
Probable cause Explanation
Random restart timer All controller outputs remain off until the timer expires.
Selected mode OFF When off is selected at the display to the controller, the unit controls all outputs off.
No power to controller If the controller does not have power, the compressor does not operate. For the controller to operate normally, it
must have an input voltage of 115 or 230/208, 265 VAC.
Manual output test The controller includes a manual output test sequence you can use to verify output operation and associated output
wiring. However, based on the current step in the test sequence, the condensate Pump may not be enabled. Refer to
the Manual Output Test section.
Unit wiring The wiring between the controller output and the Condensate Pump must be present and correct for normal
operation.
Normal operation Condensate Pump is available only with Heat Pumps. Unit is in active defrost, or outdoor temperature is below enable
point.
Unit wiring The wiring between the controller outputs and the fan relays and contacts must be present and correct for normal
condensate pump operation.
Defrost Cycle During the active defrost cycle the condensate pump power is removed. See the section on defrost control.
Table 38. Output on when the mode is off
Probable cause Explanation
Fan Configuration Fan is configured to run on high in off mode (see configuration section).
Freeze Protection While in off mode, freeze protection may be active. This will cause the indoor fan to run at high speed, and the
remote fan and auxiliary heat will be on.
Fan Delay Off The indoor fan continues to run after the compressor or auxiliary heat will be on.
Table 39. Control fuse is blown
Symptom
The generic thermostat does not work
The energy input does not work
The ventilation input does not work
The remote fan output does not work
