Heat Pump; Ducted Roof Air Conditioning System - Winnebago 2014 Sightseer Operator's Manual

HEAT PUMP

–If Equipped
Your coach may be equipped with an air
source Heat Pump built into the air conditioning
system. Because the Heat Pump operates on
electricity, it provides economical heat inside
your coach and helps reduce the use of propane
gas for heating in cooler weather.
A Heat Pump can be thought of as an air
conditioner running in reverse. An air
conditioner absorbs heat from the air on the
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
supplementary heat is often needed when the
outside temperature nears freezing. This system
is set to automatically start the propane furnace to
assist the Heat Pump if room temperature cools to
five degrees or more below the thermostat set
temperature. You may wish to manually switch
to furnace heat to maintain a higher temperature
when outside temperatures 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
Refer to the manufacturer's user guide
provided in your InfoCase for complete operating
instructions.
APPLIANCES AND SYSTEMS
• Gas Heat = Propane Furnace
• Elec Heat = Heat Pump
• Cool = Roof Air Conditioner

Check Your Air Filter
Closed or blocked vents and a dirty air filter
can hinder the efficiency of a Heat Pump.
• Ensure ceiling vents are open to distribute
Heat Pump output air.
• The A/C return air filter should be checked
monthly for dirt build-up and cleaned or
replaced as needed. See "Air Conditioner
Filter" elsewhere in this section.
DUCTED ROOF AIR
CONDITIONING SYSTEM
The furnace thermostat also controls ducted
roof air conditioner operation when the
Thermostat switch is placed in "Cool" position.
All cooling functions controlling to setpoint
have a short cycle protection time delay of three
minutes. There will be no delay if the cycle OFF
time exceeds three minutes.
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.
