When a COOL or HEAT (some models) setting is selected, the thermostat controls
the amount of cooling or heating by automatically turning the cooling compressor
or heater on and off in response to the room temperature.
Set the thermostat at the highest number for the coldest setting for cooling, and
the lowest number for warmer settings in the HEAT mode. Once the room has
reached the desired temperature, adjust the thermostat to a number providing the
most comfortable amount of cooling or heating. Higher numbers provide lower
room temperatures. Lower numbers provide warmer room temperatures.

When outside temperatures drop below 70°F (21°C) and the unit is cooling, frost
may form on the coils and block airflow into the room. If this occurs, operate the
air conditioner on the FAN setting (or CONSTANT FAN/HIGH on Energy Saver
models) to defrost the coil.
If cooling while the outside temperature is low, set the thermostat to the middle
position. Make sure the louvers are open. This will help prevent frost build-up.

The Fresh Air Vent allows the air conditioner to recirculate inside air (OFF), draw
air into the room (FRESH AIR) or exhaust stale air to the outside (VENT). See Figures
1, 2 & 3 for this operation.

cooling is desired. It may also be
for room air re-circulation without cooling when the selector switch is set to the
FAN position, this will also filter the room air.
• The FRESH AIR position allows outside air to be drawn into the room to refresh
the inside room air.
• The VENT position removes stale air from the room and exhausts it to the
outside.
• Any vent position can be used with any fan selection.
