D. Heating Operation (With Electric Heater
Option Installed).
The heat mode of operation will NOT replace
a furnace for heating your RV in cold weath-
er. The intent is to remove the chill on cool
days or mornings.
1. Turn the selector switch to “OPT HEAT”.
2. The heat strip will come on and begin heating.
3. When desired temperature level in RV is
reached, move the selector switch to “OFF” po-
sition or “FAN” position.
Thermostat does NOT control the fan/heater
ON/OFF cycle.
E. Fan Operation (Black Graphic)
This will circulate the air in your RV without

There are three positions to select from (high,
medium and low). See (FIG. 26).

2. The thermostat controls the compressor On/
OFF operation within a temperature range of
approximately 65° F and 90° F measured at the
ADB inlet.
B. “OFF” Position ( )
1. This is to turn unit o󰀨.
C. Cooling Operation (Blue Graphic)
1. Turn selector switch to cooling (blue graphic).
2. Set the thermostat at the desired temperature
level.
3. Select the fan speed that best satises your
needs:
a. HIGH COOL: Selected when maximum cool-
ing and dehumidication required.
b. MEDIUM COOL: Selected when normal or
average cooling required.
c. LOW COOL: Selected when room is at de-
sired comfort level and needs to be main-
tained. Normally this speed is used for night
time operation.
The compressor will cycle on and o󰀨 as
cooling is required to maintain the select-
ed temperature level. The fan runs when
the compressor is o󰀨 to help keep the
temperature uniform throughout the RV.
 Wait at least 2 minutes before re-
starting the compressor when it has been manu-
ally cycled o󰀨 with either the selector switch or the
temperature set lever. Otherwise, compressor will
quick-cycle and could result in compressor or sup-
ply circuit overload.
