Troubleshooting

Table 31. Compressor output 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.

Selected mode FAN ONLY When fan only is selected at the display to the controller, the unit only allows the indoor fan to energiz.

Diagnostic present	A specific list of diagnostics affects compressor operation. For more information, see the Diagnostics section in the
	manual.

No power to the	If the controller does not have power, the compressor does not operate. For the controller to operate normally, it
controller	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 compressor may not be on. Refer to
	the Manual Output Test section.

Unit wiring	The wiring between the controller output and the compressor must be present and correct for normal operation.

Indoor Coil Freeze	The compressor has been turned off because the indoor coil temperature has fallen below 35°F and has not risen
protection	above 50°F

Table 32. Indoor/remote fan outputs do not energize

Probable cause	Explanation

Random restart timer	All controller outputs remain off until the timer expires.

Normal operation	Depending on the configuration selected the fan(s) may be only cycle with the compressor output

Selected mode OFF	When off is selected at the display to the controller, the unit controls all outputs off.

Diagnostic present	A specific list of diagnostics affects fan operation. For more information, see the Diagnostics section in the manual.

No power to the	If the controller does not have power, the compressor does not operate. For the controller to operate normally, it
controller	must have an input voltage of 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 fan(s) may not be on. Refer to the Manual
	Output Test section.

Unit wiring	The wiring between the controller outputs and the fan relays and contacts must be present and correct for normal
	fan operation.

Table 33. Outdoor fan output 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.

Selected mode FAN ONLY When fan only is selected at the display to the controller, the unit only allows the indoor fan to energize.

Diagnostic present	A specific list of diagnostics affects compressor and therefore the outdoor fan operation. For more information, see
	the Diagnostics section in the manual.

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 outdoor fan may not be on. Refer to the
	Manual Output Test section.

Unit wiring	The wiring between the controller output and the outdoor fan must be present and correct for normal operation.

Coil Burst Protection	The outdoor fan has been turned off because the indoor coil temperature has risen above 140°F and has not fallen
	below 125°F

Normal operation	The outdoor fan cycles with the compressor output

Defrost Cycle	During the active defrost cycle the outdoor fan is controlled off. See the section on defrost control.

Unit wiring	The wiring between the controller outputs and the fan relays and contacts must be present and correct for normal
	fan operation.
