Aux Heat Mode - Monaco DIPLOMAT 2004 Owner's Manual

NOTE: The air conditioning system freezes moisture in the
air. It is recommended to set the blower fan speed to high
when operating in high humidity.
NOTE: There are ambient air temperature limitations in
HEAT PUMP mode. The roof air conditioner will not operate
in HEAT PUMP mode with ambient temperatures of 30º F
and below.

AUX HEAT Mode:

If the HEAT PUMP mode is selected when ambient temperature is
approximately 30° F, or if operating in HEAT PUMP mode and
temperature drops to approximately 30º F., the air conditioner will stop
Heat Pump operation and Aux Heat operation begins. AUX HEAT
mode selects the furnace as the auxiliary heat source. AUX HEAT
mode initiates automatically due to refrigerant limitations in cold
temperature. The furnace remains the primary heat source until
ambient temperature rises above 30º F. When operating in HEAT
PUMP mode with ambient temperature between 30 to 42º F, a
defrosting cycle begins approximately every 40 minutes of compressor
operation. During the defrost cycle, the blower motor will stop for five
minutes and the display will indicate DEFROST. After the defrost
cycle Heat Pump operation will resume.
