THERMOSTAT OPERATION -- COMFORT IS AT YOUR FINGERTIPS

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 frequent tempera- ture 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 oper- ates only when the thermostat calls for heating or cool- ing. 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 filter- ing is desired.

System Switch

Set the system switch for heating, cooling or auto op- eration. The auto mode allows the system to automati- cally 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.
