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 diesel fuel for heating in
cooler weather.
APPLIANCES AND SYSTEMS
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.
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 Hydronic Heating
System 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 Hydronic Heating System
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.
NOTE: Heat Pump capability is not available on
front cab A/C units (Zone 3).
To Run Fan Only (No Heat or Air)
• Press the System Button and select "Cool".
• Press the Mode Button and toggle to
"Fan High/Fan Low".
The fan will run continuously at the selected
speed and is not controlled by Thermostat setting.
The display will show current room temperature.
LCD Display Screen
The LCD Display Screen displays a variety of
features, including the room temperature and
setpoint temperature. If the word "Set" is shown,
then the setpoint or desired temperature is shown.
If the word "Set" is not shown, then the
temperature shown is the actual room
temperature in the displayed zone.
Changing Temperature Setpoints
To change the temperature, press the up or
down arrow once on the Setpoint Button. The
