Power Interruption

interrupted, the system will restart with the same settings
you have previously set.
Zone Control
The Duo-Therm Comfort Control Center will operate cool-
ing and heating appliances which the vehicle manufacturer
has designed to heat or cool different areas (
ZONES
) of
your RV. The Comfort Control Center will advise you if the
vehicle has multiple
ZONES
, by showing
ZONE 1, 2, 3 or
4
in the LCD readout.
Stage Control Operation
If the vehicle is equipped with a Duo-Therm Dual Base-
ment Air Conditioner or a Dual Basement Heat Pump, you
have an air conditioning system that is designed to opti-
mize comfort and running efficiencies. This is accomplished
by providing an on-demand secondary stage of operation.
Note:
The primary stage will continue to operate even if
there isn’t electrical power available to run the second stage.
The Comfort Control Center simplifies this operation by
allowing you to set the primary temperature set-point and
the differential temperature set-point which activates the
secondary stage. After turning on your Comfort Control
Center, perform the following steps to set and activate the
stage control operation. See FIG. B11.
1. Momentarily depress the
MODE
push-button until the
desired mode of operation is selected. (
FAN ONLY,

)
2. Momentarily depress the
FAN
push-button until the de-
sired fan speed indicator is illuminated (

AUTO
)
