•
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.
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.
DUCTED ROOF AIR
CONDITIONING SYSTEM
The furnace thermostat also controls ducted
roof air conditioner operation when the thermo-
stat switch is placed in position.
NOTE: The thermostat is equipped with a re-
placeable 2 Amp fuse located on the back
of the thermostat body.
Refer to the manufacturer’s information in
your InfoCase for complete operating instruc-
tions.
NOTE: The ducted roof air conditioning system
has ceiling registers that can be closed if
necessary to force more cool air toward
a specific area of the coach or to route
cool air away from a specific area. If too
many vents are closed, however, it can
cause the air conditioner unit to shut
down, particularly in high humidity
conditions.
All cooling functions controlling to setpoint
have a short cycle protection time delay of 3 min-
utes. There will be no delay if the cycle OFF time
exceeds 3 minutes.

Electric Heat = Heat Pump
