THERMOSTAT OPERATION −− COMFORT IS AT YOUR FINGERTIPS
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 time-
of-day setpoints for both heating and cooling.
Refer to the user’s information manual provided
with your particular thermostat for operation
details.
Though your thermostat may vary somewhat from
the description below, its operation will be similar.
Temperature Setting Levers
Set the lever or dial to the desired temperature
setpoints for both heating and cooling. Avoid fre-
quent temperature adjustment; turning the unit off
and back on before pressures equalize puts
stress on the unit compressor.
Fan Switch
In AUTO or INT (intermittent) mode, the blower
operates only when the thermostat calls for heat-
ing 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 furnace is operating. This mode is required
when constant air circulation or filtering is desired.
