The thermostat controls the room temperature by turning
either the compressor or electric heater on and off while the
fan is running. Turn the thermostat control clockwise to
provide a cooler room temperature; turn it counterclockwise
to provide a warmer one.
NOTE
: If the fan cycle switch (see Additional Control Inputs)
is in the CYCLE mode, both the compressor and fan will
cycle on and off during the cooling modes.
