Thermostat Operation
The wall-mounted thermostat controls your air conditioner.
The thermostat is available in various congurations from
dierent manufacturers. The information below is typical for
most thermostats. Ask your dealer for specic information
regarding the model of thermostat installed.
Fan Switch
In AUTO or INT (intermittent) 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
is operating. This mode is required when constant air
circulation or ltering is desired.
On models without a fan selection switch, the fan will cycle
with the outdoor unit.
