HEAT PUMP OPERATION
In this mode, the compressor will cycle On/Off based on the Room/Set temperature. The Fan will run first and
then the compressor will turn on in approximately 3 minutes. If the Fan is set to Auto, the Fan will stop 30
seconds after the compressor stops. If the outdoor temperature is below 38°F, the heat pump will not work. If
the system contains a furnace, the Thermostat will activate the furnace when the temperature is below 38°F and
use the furnace as the main source for heat. The Fan will continue to run as set. Once the outdoor temperature
rises above 45°F, the Thermostat will switch back to the Heat Pump, and no longer use the furnace. If the heat
pump runs for more than 20 minutes continuously and the Room temperature is below 64°F, the Thermostat
will activate the Furnace and run both heat sources to quickly heat the RV.
HEAT STRIP OPERATION
In this mode, the Heat Strip will cycle On/Off based on the Room/Set temperature. The Fan has a 20 second
delay to allow heat buildup. Once the Room temperature reaches the Set temperature, the Heat Strip will shut
off and the Fan will run for additional 30 seconds in the Auto setting to blow the residual heat from the ducts. If
the Fan is set to On, it will continue to run at the set speed.
FURNACE OPERATION
In this mode, the Thermostat provides a 12VDC trigger to activate the RV Furnace. The Fan may or may not
run based on the Fan settings. You can select Auto, On High/Medium/Low, or Off in the Furnace Mode. If
Auto is selected the Fan will run for 30 seconds after the Room temperature reaches the Set temperature. If On
is selected the Fan will run at the set speed regardless of Room temperature.
