Heat Pump - Winnebago Journey Owner's Manual

Heat Source Switch
ELECTRIC = Heat Pump
GAS = Furnace
• Adjust the temperature setpoint to personal
preference if needed. See "Changing Tem-
perature Setpoints."
Digital Thermostat Display
The digital display normally shows current
room temperature, with the word "ROOM" in
small letters at the left side of the display. When
you press the temperature selector button up or
down, the display will show the word "SET" and
the new temperature setpoint until you release
the button.
Change Temperature
To set the temperature to a new temperature,
simply press the Temperature Selector button up
or down until the temperature you want appears
in the display. The word "SET" will also appear
at the left side of the display while you are chan-
ing the temperature setpoint. A few seconds after
you release the temperature selector button, the
display will return to showing the current room
temperature.
Cooling (A/C):
• Slide the thermostat switch to Cool position.
• Slide the Fan Mode and Fan Speed Switches
to the desired positions.
On/Low: A/C compressor cycles on and off
with the thermostat while fan runs continu-
ously at low speed.
APPLIANCES & INTERIOR FEATURES
On/High: A/C compressor cycles on and off

ously at high speed.
Auto/Low: Fan runs at low speed and cycles
on and off with the A/C compressor as con-
trolled by the thermostat.
Auto/High: Fan runs at high speed and
cycles on and off with the A/C compressor as
controlled by the thermostat.
• Adjust the temperature setpoint to personal
preference if needed. See "Changing Tem-
perature Setpoints".
To Run Fan Only (No Heat or Air)
• Set Thermostat switch to OFF.
• Slide Fan Mode switch to On.
• Place Fan Speed switch to Lo or Hi as
desired
• The fan will run continuously at the selected
speed and is not controlled by thermostat set-
ting. The display will show current room
temperature.
HEAT PUMP - Optional
Your coach may be optionally equipped with
an air source heat pump built into the central air
conditioning system. Because the heat pump
operates on electricity, it provides economical
heat inside your coach and helps reduce the use
of LP gas for heating in cooler weather.
A heat pump can be thought of as an air con-
ditioner running in reverse. An air conditioner
absorbs heat from the air 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 tempera-
ture.
The efficiency of a heat pump decreases as the
outdoor air temperature drops, so supplementary
heat is often needed when the outside tempera-
ture nears freezing. This sytem is set to automat-
ically start the LP gas furnace to assist the heat
pump if room temperature cools to 5 degrees F or
more below the thermostat setpoint. You may
wish to manually switch to furnace heat to main-
tain a higher temperature when outside tempera-
