(1) Control for indoor freezing prevention
If the temperature of the indoor heat exchanger
stays below approximately 0°C for four minutes
during cooling or dry, this control stops the
compressor. Over 2˚C the compressor will run
again.
(2) Control for cold air blowing prevention
When heating begins, this control stops the indoor
fan until the temperature of the indoor heat
exchanger reaches 26°C. It also stops the fan if
the temperature goes below 23°C during
operation.
(3) Indoor fan and operating frequency
The indoor fan has 12 speeds, and changing is
done in four stages, "Auto", "High", "Med", and
"Low". The relations between the indoor fan
speed, air quantity setting, operating frequency,
and indoor heat exchanger are shown in the
following charts.
