Freeze-up Protection Control
Outline
During cooling operation, the signals sent from the indoor unit allow the operating frequency
limitation and prevent freezing of the indoor heat exchanger. (The signal from the indoor unit is
divided into zones.)
Details
The operating frequency limitation is judged with the indoor heat exchanger temperature 2 seconds
after operation starts and 30 seconds after the number of operation room is changed.
3.7
Heating Peak-cut Control
Outline
During heating operation, the indoor heat exchanger temperature determines the frequency upper
limit to prevent abnormal high pressure.
Detail
The operating frequency is judged with the indoor heat exchanger temperature 2 minutes after
the operation starts and (
) seconds after the number of operation room is changed.
The maximum value of the indoor heat exchanger temperature controls the following (excluding
stopped rooms).
