Heat Pump

Your coach is 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
4-16
extract heat from the outside air on a cold day and
carry it to the inside of the coach to maintain a
comfortable temperature.
The efficiency of a heat pump decreases as the
outdoor air temperature drops, so supplementary
heat is often needed when the outside
temperature nears freezing. This system is set to
automatically start the propane furnace to assist
the heat pump if room temperature cools to 5
degrees or more below the thermostat set
temperature. You may wish to manually switch
to propane furnace heat to maintain a higher
temperature when outside temperatures begin to
reduce the efficiency of the heat pump. The heat
pump will not operate when the outside
temperature falls below 36 degrees F.
To Run Fan Only (No Heat or Air)
1. Set Thermostat Switch to COOL.
2. Press the "Mode" side of the Mode/Zone
Button.
3. Toggle between settings and select FAN
HIGH/FAN LOW.
4. The fan will run continuously at the selected
speed and is not controlled by thermostat
setting. The display will show current room
temperature.
LCD Thermostat Display
The LCD Display Screen displays a variety of
features, including the room temperature and
setpoint temperature. If the word "Set" is shown
above the temperature, then the setpoint or
desired temperature is shown. If the word "Set" is
not shown, then the temperature shown is the
actual room temperature.
Changing Temperature Setpoints
To change the temperature, press the up or
down arrow once on the Setpoint Button. The
word "Set" will appear on the display screen.
This puts the system in the mode to change the
setpoint temperature. Then, press the up or down
arrow until your have reached your desired
temperature.
