compressor and the fan to come on at
slightly different times, which allows
full power to the compressor on start
up.
The fan off delay allows the fan to
continue running after the compressor
has shut off. This distributes the
cooling that would otherwise stay
trapped in the air conditioning coils
through the ducts. Ideally the timing
would be set so the fan shuts off just as
the cool air is exhausted. If this timing
is set too long the fan may begin
blowing warm air before it shuts off.
Shortening the fan-off delay will
prevent this.
