Heat Pump; Ducted Roof Air Conditioning System - Winnebago SightSeer Owner's Manual

Further Information
Please see the furnace operating instructions
provided in your InfoCase for further
information, including operating precautions,
and periodic maintenance. See the Coach
Maintenance Schedule for recommended
intervals.
NOTE: If the furnace burner has any residuals
of metal protectant or lubricants used
during manufacture of the furnace, it
may smoke slightly when the furnace is
used for the first time and may set off
your smoke alarm.
We recommend that you provide
adequate ventilation when using the
furnace for the first time to avoid a
nuisance smoke alarm.
We do not recommend removing the
smoke alarm battery.

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 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
APPLIANCES AND SYSTEMS
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:
See the air conditioning/heat pump
manufacturer's information in your InfoCase for
complete operating instructions.
• Gas Heat = Gas 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.
• Be sure 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 3
minutes. There will be no delay if the cycle OFF
time exceeds 3 minutes.
NOTE: The ducted roof air conditioning system
has ceiling registers that can be closed if
necessary to force more cool air toward
