DIGITAL THERMOSTAT OPERATIONDIGITAL THERMOSTAT OPERATION

DIGITAL THERMOSTAT OPERATION

Your heat pump is operated from the control panel of the

electronic wall thermostat. When the furnace is connected

to this thermostat, it will operate from the same control

panel.

Identification and operational descriptions for all con-

trol panel switches and display are listed below:

Liquid Crystal DisplayLiquid Crystal Display

Liquid Crystal Display: This display will be illumi-

nated any time the system is in operation.

NOTENOTE

NOTE:

When switching from OFF to any other mode, the

liquid crystal display may not illuminate for approxi-

mately three minutes.

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: ACTUAL, COOL

and HEAT.

The operator may choose the mode he desires to

view by depressing the "MODE" switch. Each time

the MODE switch is depressed, the display ad-

vances to the next mode. If the display is left in either

COOL or HEAT, the thermostat will automatically

return the display to ACTUAL in approximately three

minutes.
