THERMOSTAT

The cooling setting determines the temperature at

which the air conditioner will start to operate. The heat

setting determines the temperature at which the heating

system will start to operate.

UP: Depressing this switch increases the temperature

setpoint.

DOWNDOWN

DOWN: Depressing this switch decreases the tempera-

ture setpoint.

ADJUSTING SETPOINTADJUSTING SETPOINT

ADJUSTING SETPOINT

To adjust the setpoint for heating or cooling, press the

MODE button until the arrow on the display indicates the

desired setpoint you which to change, cool or heat. The

display will indicate the current setpoint of the thermostat.

Press UP or DOWN to change the setpoint. Once the new

desired setpoint is displayed, press the MODE button until

the arrow is pointing to ACTUAL. If the thermostat is left in

the COOL or HEAT mode, the display will return to AC-

TUAL in about 3 minutes. After the display returns to

ACTUAL, it takes 15 to 30 seconds for the thermostat to

recognize the changes made to the setpoint.

AIR CONDITIONER & THERMOSTATAIR CONDITIONER & THERMOSTAT

AIR CONDITIONER & THERMOSTAT

This packaged air conditioning heat pump contains a dual

compressor refrigeration system. Each compressor is con-

nected to a separate refrigeration circuit and air system.

The system can be operated with a single compressor when

the cooling requirement is low, or with two compressors

when maximum cooling performance is required.

The first compressor and refrigeration circuit is referred to

as "

Stage 1 CoolingStage 1 Cooling

Stage 1 Cooling". The second compressor and refrig-

eration circuit and air system is referred to as "

The thermostat senses room temperature is two degrees

higher than set point.

The vehicle is being powered by the on-board generator. A

30 amp shoreline by itself will not provide enough power to

operate the 1st and 2nd Stage cooling.

Switching and control of the 1st and 2nd Stage cooling is

automatic. When operating from shoreline, the system

automatically limits operation to 1st Stage cooling only.

When the shoreline is plugged into the on-board generator,

the system automatically allows 1st and 2nd Stage cooling.

However, if powering both systems from the generator and

cooling demand does not required both systems to oper-

ate, Stage 2 will shut down and only Stage 1 will operate.

THERMOSTATTHERMOSTAT

THERMOSTAT

This thermostat controls the 12V DC heating and air

conditioning systems. It can control one stage of heat and

two stages of cooling and has an auxiliary heat mode for

gas heating. Changeover from heating to cooling is opera-

tor controlled. The thermostat can not make this change.

Time delay circuits have been incorporated to protect the

heat pump system components. The time delay is 3

minutes between off and on cycles. Thirty seconds delay is

at the turn "ON" of the compressors. This is to allow time

for the generator to stabilized on initial starting. The bal-

ance of the delay (2.5 minutes) occurs when the compres-

sor cycles "OFF". This is to allow the compressor pres-

sures to balance before restarting. There is a thirty second

delay and two degrees between the first and second stage

cooling operation.

Your air conditioner is operated from the control panel of

the electronic wall thermostat. When the furnace is con-

nected to this thermostat, it will operate from the same

control panel.
