FURNACE-A/C THERMOSTAT OPERATION CHART
The following chart shows the system functions with the “Heat/Cool” thermostat. Disregard references
to heat functions when using the “Cool Only” thermostat in the rear bedroom.
HEAT PUMP
–If Equipped
Your coach may be equipped with an air
source heat pump built into the air conditioning
system. Because the heat pump operates on
electricity, it provides economical heat inside
your coach and helps reduce the use of propane
gas for heating in cooler weather.
A heat pump can be thought of as an air
conditioner running in reverse. An air
conditioner absorbs heat from the air on the
inside of the coach and moves it to the outside.
The heat pump does exactly the opposite. Even
cold air contains some heat, so a heat pump will
extract heat from the outside air on a cold day and
carry it to the inside of the coach to maintain a
comfortable temperature.
