C. HEAT PUMP OPERATION
(To set heating temperatures for vehicles equipped with a Duo-
Therm rooftop or basement heat pump. To operate cooling mode
with a heat pump, see "B. Cooling Mode Operation", Page 3.)
1. Momentarily depress and release the MODE push-button until
the HEAT PUMP indicator on the LCD is illuminated.
2. If you have not previously set your fan speed, you may do so
by depressing and releasing the FAN push-button to select the
desired fan speed.
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 heat pump's
compressor will come on and the heating 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 heating, 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 above. Repeat entire procedure for each additional
zone.

the FURNACE indicator on the LCD is illuminated.
2. The A/C fan does not operate in the FURNACE mode.
3. Depress and release the UP push-button to increase the

temperature. The final selected SET-POINT will be displayed
in the LCD area of the Comfort Control Center.
4. Your Duo-Therm air conditioning system will not operate when
the Comfort Control System is in the FURNACE mode. For
cooling, change the MODE to COOL.
5. If your vehicle contains more than one ZONE, depress the
