Heat Pump - Winnebago Journey Manual

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
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.
NOTE: Heat Pump capability is not available on
front cab A/C units (Zone 3, if equipped).
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.
APPLIANCES AND SYSTEMS
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
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.
NOTE: The temperature setpoint cannot be
adjusted in the following situations:
When the Thermostat system is set to
OFF, when the zone is turned off for
either heating or cooling mode, or when
the fan is set to be running continuously
in either high or low speed.
Supply and Return Air Vents
Supply and Return Air Vents are located
throughout the ceiling of the coach. The Supply
Vents produce airflow. The Return Vents are for
air intake, in which the air goes back into the air
handler. There is a distinguishable difference
between the two - Return Air Vents are equipped
with a removable filter inside, and Supply Air
Vents are not.
