Compressor Delay (P5)

The defrost control has a field−selectable function to reduce occasional sounds that may occur while the unit is cycling in and out of the defrost mode.

SUnits with defrost control 100269−02: The compressor will be cycled off for 30 seconds going in and out of the defrost mode when the compressor delay jumper is removed.

SUnits with defrost control 100269−04: The compressor will be cycled off for 30 seconds going in and out of the defrost mode when the compressor delay jumper is installed.

NOTE

when jumpering the TEST pins. Time Delay

The timed-off delay is five minutes long. The delay helps to protect the compressor from short-cycling in case the power to the unit is interrupted or a pressure switch opens. The delay is bypassed by placing the timer select jumper across the TEST pins for 0.5 seconds.

Test Mode (P1)

A TEST option is provided for troubleshooting. The TEST mode may be started any time the unit is in the heating mode and the defrost thermostat is closed or jumpered. If the jumper is in the TEST position at

power-up, the defrost control will ignore the test pins. When the jumper is placed across the TEST pins for two seconds, the defrost control will enter the defrost mode. If the jumper is removed before an additional 5−second period has elapsed (7 seconds total), the unit will remain in defrost mode until the defrost thermostat opens or 14 minutes have passed. If the jumper is not removed until after the additional 5−second period has elapsed, the defrost will terminate and the test option will not function again until the jumper is removed and re−applied.

Defrost Control Diagnostic LEDs

The defrost board uses two LEDs for diagnostics. The LEDs flash a specific sequence according to the condition.
