Page 7: Operation
OPERATION Sequence of Operation Cooling When the thermostat is in the cooling mode, the O circuit is powered which energizes the reversing valve. Upon cooling demand, the thermostat closes circuit R and Y. Closing R and Y closes the unit contactor, starting the compressor and outdoor fan. - Page 8 jumper is not in place, the control defaults to a 90-minute defrost interval. The maximum defrost period is 14 minutes and cannot be adjusted. 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.
- Page 9 Adjusting Airflow (Variable Speed Motor Equipped Units Only) There is no blower “on” delay after a call for heating or cooling. Blower “off” delay is 90 seconds after the thermostat is satisfied. Variable Speed Motor Units equipped with a variable speed circulation air blower motor will deliver a constant airflow within a wide range of external static pressures.
