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:
D Check to see that all
electrical disconnect
switches are ON.
D Make sure the room
thermostat temperature
selector is properly set.
D Make sure the room
thermostat system switch is
properly set.
D Replace any blown fuses, or

and have it handy before
calling.
