A.A.

LIQUID CRYSTAL DISPLAYLIQUID CRYSTAL DISPLAY

LIQUID CRYSTAL DISPLAY: This display will be

illuminated any time the system is in operation.

The display shows the operator both the mode of the

display (indicated by the arrow at the left side of the

display) and the temperature for that mode. There are

three display modes:

ACTUALACTUAL

ACTUAL,

COOLCOOL

COOL and

HEATHEAT

HEAT. The

operator may choose the mode to view by depressing

the "

MODEMODE

MODE" switch. Each time the

MODEMODE

MODE switch is

depressed, the display advances to the next mode. If

the display is left in either

COOLCOOL

COOL or

HEATHEAT

HEAT, the thermo-

stat will automatically return the display to

ACTUALACTUAL

ACTUAL in

approximately three minutes.

A description of the three modes is:

ACTUALACTUAL

ACTUAL: When in this mode, the display is indicating

current room temperature.

COOL SETCOOL SET

COOL SET: When in this mode, the display is indicating

the current cooling setpoint temperature. At this time

the cooling system setpoint temperature may be ad-

justed up or down to meet the individual comfort level.

See "Adjusting Setpoint" for further instructions.

HEAT SETHEAT SET

HEAT SET: When in this mode, the display is indicating the

current heating system setpoint temperature. At this

time, the heating system setpoint temperature may be

adjusted up or down to meet the operator's comfort

level. See "Adjusting Setpoint" for further instructions.

All three display modes can be accessed without affecting

the operation of the system. The system operation will

remain normal unless a change is made to the setpoint to

force a change in the system operation.

SYSTEM SWITCHSYSTEM SWITCH

SYSTEM SWITCH: The system switch has four posi-

tions to control the operation of the heating and cooling

systems. They are as follows:

COOLCOOL

COOL: When in the "

COOCOO

COOL" position, 1st and 2nd

Stage cooling will cycle from the cooling system setpoint.

Blower operation will be controlled by the position of the

Cooling Fan Switch.

HEATHEAT

HEAT: When in this position, the heating system will

cycle from the heating system setpoint. The heating

blower will operate per the heating system manufac-

turer specifications.

OFFOFF

OFF: When in the "

OFFOFF

OFF" position, no thermostat or

system operation will occur. The liquid crystal display

will indicate room temperature until backup power is

depleted (approximately 2 minutes).

AUX. HEATAUX. HEAT

AUX. HEAT: When in the auxiliary heat mode the gas

furnace will heat your coach. The fan will operate per

cooling blower operates at high speed and cycles "OFF"

and "ON" with the 1st Stage compressor. The 2nd

Stage cooling will cycle "ON" and "OFF" as needed.

LOW AUTOLOW AUTO

LOW AUTO: When in LOW AUTO position, the cooling

blower operates at low speed and cycles "OFF" and

"ON" with the 1st Stage compressor, the 2nd Stage

cooling will cycle "ON" and "OFF" as needed.

MOMENTARY SWITCHESMOMENTARY SWITCHES

MOMENTARY SWITCHES: Momentary Switches are

activated by depressing the center of the switch. There

are three momentary switches:

MODEMODE

MODE: Depressing this switch advances the display

mode from ACTUAL to COOL, HEAT and back to

ACTUAL.

When using this switch, you are indicating your desire

to check or adjust the setpoint temperatures for cooling

or heating.

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.

UPUP

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.
