1G. OPERATION
The recreational vehicle manufacturer has equipped the
vehicle with Duo-Therm's Comfort Control Center™. The
Comfort Control Center has been designed for you to
easily operate all the air conditioning and gas heating
appliances found in your vehicle from one location.
In order to familiarize yourself with the operation of the
Comfort Control Center, the following diagram along with
the accompanying text will explain all the functional char-
acteristics of the system.
A. LIQUID CRYSTAL DISPLAY – The 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 the Comfort Control Center, you
will see that the LCD readout will only show the options
available based on the appliances installed on your ve-
hicle. An incandescent light will illuminate the LCD area
when a selector button is pushed for easy reading at all
times.
B. 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.

C. MODE SELECTOR BUTTON – Modes of operation avail-
able are: OFF, FAN ONLY, COOL, HEAT PUMP, FUR-
NACE and HEAT STRIP. Remember, the 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.
To determine the Comfort Control Center options avail-
able to you, depress and release the MODE push-button
until it goes through all selections.
D. TEMPERATURE SELECTOR BUTTONS – The tempera-
ture Set-point range is from 40° to 99° Fahrenheit. Deter-
mination 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 DN push-
button until the desired temperature is shown in the LCD
readout area of the Comfort Control Center.
E. ZONE AND STAGE SELECTOR BUTTONS – A ZONE
is also established at the time of installation of the Comfort
Control Center. If you have one air conditioner, you will
have one ZONE. If the 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 the 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 tempera-
ture 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
the vehicle, simultaneously depress the FAN and MODE
push-buttons. Zone 1 will be the first Zone to appear in the
LCD readout. Continue to depress and release these
buttons until you see Zone 1 reappear.
If the vehicle has a dual basement air conditioner or dual
heat pump system, the word STAGE will be illuminated.
Both of these units operate in two different stages, and the
word STAGE will show when the second stage operation
has been selected. To select the second stage, simulta-
neously depress the FAN and MODE push-buttons.
