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 system is set to automat-
ically start the LP gas 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 furnace heat to
maintain a higher temperature when outside tem-
peratures 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 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.
•
Whent he 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.
Have you checked your air filter lately?
Closed or blocked vents and a dirty air filter
can hinder the efficiency of a heat pump. See Air
Conditioner Filter for location and instructions.
•
Be sure ceiling vents are open to distribute
heat pump output air. Also make sure furni-
ture, clothing items, packages or other
obstructions do not block the air return air
grilles beneath the rear bed.
•
The filter should be checked monthly for dirt
build-up and replaced as needed. The air fil-
ter is a disposable woven fiberglass type,
which cannot be cleaned and should be
replaced when coated with dust.
