instructions provided in your Owner InfoCase

for further information, including operating pre-

cautions, and periodic maintenance.

HEAT PUMP - Optional

Your coach may be optionally equipped with

an air source heat pump built into the air condi-

tioning 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.

DUCTED ROOF AIR CONDITIONING

SYSTEM

Front and rear air conditioner units are con-

trolled by separate wall thermostats. The front

thermostat is located on a galley wall. The rear

thermostat is located in the bedroom.

The front thermostat also controls furnace

operation when the SYSTEM switch is placed in

HEAT position. (See LP Gas Furnace).

The rear bedroom thermostat controls the rear

air conditioner only and does not have HEAT

position unless equipped with the heat pump

option.

NOTE: These thermostats are equipped with a

replaceable 2 Amp fuse located on the

back of the thermostat body.
