A. LIQUID CRYSTAL DISPLAY – Your Comfort Control

Center is equipped with a liquid crystal display (LCD)
that identifies the mode of operation, the temperature
set-point, the zone identification and the fan speed. The
Comfort Control Center is designed to accept and
control many varied air conditioning and gas heating
appliances. When you begin to first operate your Com­fort Control Center, you will see that the LCD readout will
only show the options available based on the appliances
installed on your vehicle. An incandescent light will
illuminate the LCD area when a selector button is
pushed for easy reading at all times.

B. MODE SELECTOR BUTTON – Modes of operation

available are: OFF, FAN ONLY, COOL, HEAT PUMP,
FURNACE, HEAT STRIP and AUX. HEAT. Remem­ber, your LCD readout will only show the options
available based on the appliances installed on your
vehicle. To select the mode of operation, momentarily
depress the MODE push-button. You will need to
continue to depress and release the button until the
desired mode is shown in the LCD readout area on the
Comfort Control Center.

C. FAN SPEEDS – Possible available fan speeds are:

LOW, MEDIUM, HIGH and AUTO. To select the desired
fan speed, momentarily depress the FAN push button.
You will need to continue to depress and release the
FAN button until the desired fan speed is shown in the
LCD readout area of the Comfort Control Center.

D. TEMPERATURE SELECTOR BUTTONS – The tem-

perature Set-point range is from 40° to 99° Fahrenheit or
4° to 37° Celsius. Determination of Fahrenheit or Celsius
standard is done at the time of your manufacturer's
installation of the Climate Control Center. To set the
temperature at your comfort level, simply depress and
release the UP or DOWN push-button until the desired
temperature is shown in the LCD readout area of the
Comfort Control Center.

E. ZONE SELECTOR BUTTON – A ZONE is also

established at the time of installation of your Comfort
Control Center. If you have one air conditioner, you will
have one ZONE. If your vehicle has more than one cooling
system, depending on the manufacturing installation,
you may have 2, 3 or 4 ZONES. Zones are defined and
preset by your manufacturer. A zone is an area of
cooling/heating which is controlled independently within
that area, and regulated at the Comfort Control Center.
A typical example of a two zone application would be a
vehicle with two air conditioning systems, one in the front
area (living room, kitchen) and one in the back section
(bedroom and bath). The front area could be established
as ZONE 1 and the back section ZONE 2. You can select
the desired temperature and fan speeds for each zone
independently, thereby keeping your bedroom cooler
than the front portion of the vehicle. To determine the
number of established zones in your vehicle, depress the
ZONE push-button. ZONE 1 will be the first ZONE to
appear in the LCD readout. The ZONE number selected
will begin to flash and will flash for approximately 30
seconds or until another ZONE has been selected.
Continue to depress and release the ZONE button until
you see ZONE 1 reappear.

F. ON/OFF SWITCH – The ON/OFF switch is located on

the lower right hand edge of the Comfort Control Center.
Move the lever from side to side to change status.

To determine the Comfort Control Center options avail­able to you, depress and release the MODE push-button
until it goes through all selections.

DUO-THERM COMFORT CONTROL CENTER

The Comfort Control Center allows you the freedom of controlling your vehicle's temperature to provide you with a comfortable
environment to enjoy your life-style. With just a few simple steps, you can control which mode of operation you will use, the vehicle
temperature and the fan speeds.

hand edge of the Control Center on the ON position. To
do this, simply move the lever to the right.

2. Momentarily depress and release the MODE push­button until the FAN ONLY indicator on the Liquid
Crystal Display (LCD) is illuminated.

3. Momentarily depress and release the FAN push­button until the desired fan speed indicator (LOW,
MED, HIGH, AUTO) is illuminated. If your vehicle is
equipped with a heat pump or a dual basement air
conditioning system, your selection choice will be
LOW, HIGH or AUTO.

4. After approximately 5 seconds, the selected fan
speed will come on. The MODE and FAN speed you
have selected will remain shown in the LCD area of the
Control Center until you change your selection.

5. If your vehicle contains more than one ZONE, depress
the ZONE push-button to select ZONE 2, and repeat
procedures from step two above. Repeat entire proce­dure for each additional zone.

B. COOLING MODE OPERATION

(To set cooling temperatures and fan speeds on Duo­Therm Air Conditioners & the cooling mode of Duo­Therm Heat Pumps)

1. Momentarily depress and release the MODE push­button until the COOL indicator on the LCD is illumi­nated.

2. Depress and release the FAN push-button to select
your desired fan speed (LOW, MEDIUM, HIGH or
AUTO). If your vehicle is equipped with a heat pump or
a dual basement air conditioner system, your selec­tion choice will be LOW, HIGH or AUTO.

3. Depress and release the UP push-button to increase
the temperature or the DOWN push-button to de­crease the desired temperature. The final selected
SET-POINT will be displayed in the LCD area of the
Comfort Control Center.

4. After a delay of approximately 2 minutes the air
conditioner's compressor will come on and the cooling
process will begin. Once the room temperature reaches
the selected SET-POINT, the compressor will cycle
off. Once the Comfort Control Center senses the need
for cooling, the compressor will restart in approxi­mately two minutes. At this point, the fan will either:
a.continue to operate in the single selected fan speed
or,
b.cycle OFF and ON with the compressor if the AUTO
fan speed has been selected.

5. If your vehicle contains more than one ZONE, depress
the ZONE push-button to select ZONE 2, and repeat
procedures from Step 1. Repeat entire procedure for
