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. |
