SECTION 8
APPLIANCES & INTERIOR FEATURES
Fan:
•
Slide the 'Fan Mode' switch to "On" posi-
tion. The fan will run continuously at high
speed and is not controlled by thermostat set-
ting. The display will show current room
temperature.
Digital Thermostat Display
The digital display normally shows the current
room temperature, with the word "room" in
small letters at the left side of the display. When
you press the temperature selector button, the
display will show the word "set" and the desired
new temperature setpoint until you release the
button.
Change Temperature
To set the thermostat to a new temperature, sim-
ply press the arrow button up or down until the
temperature you want appears in the display.
When you press the arrow button, the word "set"
will appear in at the left side of the display while
you are changing the temperature setpoint. A
few seconds after you release the arrow button,
the display will return to the current room tem-
perature indication.
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
temperature.
The efficiency of a heat pump decreases as
the outdoor air temperature drops, so supple-
mentary heat is often needed when the outside
temperature nears freezing. This system is set to
automatically start the LP gas furnace to assist
8-14
the heat pump if room temperature cools 5
degrees F or more below the thermostat setpoint.
You may wish to manually switch to furnace
heat to maintain a higher temperature when out-
side temperature falls below 36 degrees F.
To operate the heat pump:
•
Slide the Thermostat switch to Electric Heat
mode.
•
If the inside temperature is 5 degrees or more
below the thermostat set point, both the heat
pump and the furnace will run initially to
bring the interior temperature up to the set
point as quickly as possible. (If the inside
temperature is 4 degrees or less below the set
point, then only the heat pump will run ini-
tially.)
•
When the thermostat is satisfied, the heat
pump and furnace will both shut off.
•
When the thermostat calls for heat again,
only the heat pump will run. The heat pump
will remain the sole heat source unless it
cannot maintain the inside temperature. If
the inside temperature falls five degrees
below the set point, the furnace will assist
the heat pump until the set point is reached.
If the furnace must assist the heat pump three
times in a row, the thermostat will shut down the
heat pump for two hours and the furnace will
take over as the heat source. After two hours the
heat pump will become active again and try to be
the primary heat source.
The furnace acts as a standby heat source if
the outside temperature drops below a point that
the heat pump can no longer extract enough heat
from the outside air to maintain the desired
inside temperature.
