The comfort control operates the HVAC (heating, ventilating and air
conditioning) system. A small wall-mounted thermostat located in the living
room, the comfort control operates all the roof air conditioners functions as
well as the LP-Gas furnace operations. The comfort control uses a liquid
crystal display to inform the operator of its current program status.
There are six different functions of the HVAC system: OFF, FAN, COOL,
HEAT PUMP, AUX. HEAT and FURNACE. The repeated pressing of the
MODE button makes these selections. The FAN button controls the roof air
conditioner fan speed. Three speeds are available: low, medium and high. Fan
speed control applies to the roof air conditioner's blower speed only. Selecting
the fan speed AUTO adjusts the fan speed automatically, depending on
temperature set point and actual temperature in a selected zone. The roof air
conditioners will use all three blower speeds (low, medium or high) in the
COOL mode when selecting AUTO fan when selecting AUTO fan if operat-
ing in HEAT PUMP mode, only low or high blower speeds are available.
There are separate operating zones for the motorhome designated Zone 1 and
Zone 2. Pressing the zone button toggles the zone selection. The selected zone
number flashes while the other remains steady. Pressing the UP or DOWN
buttons controls the temperature range for any HVAC function.
NOTE: The Comfort Control must be ON to operate any
function of the HVAC system. The Comfort Control must be
in the same mode for all zones to function properly. One zone
cannot be on COOL while the other zone uses FURNACE.
DO NOT attempt to mix the modes for separate zones.
Heating or cooling the motorhome will not be any faster by
selecting a very high or very low temperature setting.
Comfort Control Reset:
Should the comfort control exhibit unusual symptoms or not respond to
commands, it may require a reset. The reset establishes factory defaults.
To reset:
• The Battery Cut-off switch must be on.
• Press and hold MODE and ZONE buttons simultaneously
while switching the ON/OFF switch to ON.
• Five to ten seconds after switching the comfort control
ON. The letters "FF" appear. Release the MODE and
ZONE buttons. The comfort control backlighting will
remain illuminated. The factory default settings of 72° F
for COOL and 68° F for FURNACE are then established.
• Select the MODE to confirm factory default. Set
desired setting in the comfort control using normal
programming procedures.
