Though your thermostat may vary somewhat from

the description below, its operation will be similar.

TEMPERATURE

LEVERS

Set the indicator lever or dial to the desired

temperature setpoints for both heating and cooling.

FAN

SWITCH

In AUTO or INT mode, the blower operates only

when the thermostat calls for heating or cooling.

This mode is generally preferred when humidity

control is a priority. The ON or CONT mode

provides continuous indoor blower operation,

regardless of whether the compressor or burners are

operating. This mode is required when constant air

circulation or filtering is desired.

SYSTEM

SWITCH

Set the system switch for heating, cooling or auto

operation. The auto mode allows the system to

automatically switch from heating mode to

cooling mode to maintain predetermined comfort

settings.

TEMPERATURE

INDICATOR

The temperature indicator displays the actual

room temperature.

PROGRAMMABLE

THERMOSTATS

Your Lennox system may be controlled by a

programmable thermostat. These thermostats

provide the added feature of programmable

setpoints for both heating and cooling. Refer to

the user's information manual provided with

your particular thermostat for operation details.

If your system fails to

operate, check the following

before calling for service:

electrical disconnect

switches are ON.

selector is properly set.

Make sure the room

thermostat system switch is
