THIS APPLICATION PROVIDES AUTOMATIC CONTROL OF AN AIR TO AIR HEAT PUMP AND INTEGRATED
ECONOMIZER WITH DIFFERENTIAL ENTHALPY CONTROL AND HIGH TEMPERATURE LIMIT (SEE APP
GUIDE FOR DETAILED SEQUENCE). REVERSING VALVE IS ENERGIZED IN COOLING MODE AND INITIATES
COOLING CYCLE BASED ON 24 VAC SUPPLIED CONFIGURER HAS THE OPTION TO RUN THE HEAT PUMP
IN A “COMFORT MODE” OR “SAVINGS MODE.” THE NORMAL MODE WILL OPERATE THE HEAT PUMP
AUXILIARY HEAT BASED ON CONFIGURER SELECTED HEATING SETPOINT. IN THE “SAVINGS MODE”
THE HEATING SETPOINT IS DEPRESSED SO THAT ELECTRIC, AUXILIARY HEAT OPERATES LESS
FREQUENTLY. REFER TO APPLICATION GUIDE TO REFERENCE SETUP, SETBACK OPERATION AS WELL
AS ADAPTIVE INTELLIGENT RECOVERY OPERATION. SYSTEM SUPPLY FAN AUTOMATICALLY OPERATES
IN A CONTINUOUS MANNER DURING OCCUPIED PERIODS AND CYCLES ON A CALL FOR COOLING
DURING UNOCCUIPED PERIODS TO MEET THE NEED OF PREVAILING BUILDING CODES.
