3.6
Freeze-up Protection Control
During cooling operation, the signal sent from the indoor unit controls the operating frequency
limitation and prevents freezing of the indoor heat exchanger. (The signal from the indoor unit is
divided into zones.)
The operating frequency limitation is judged with the indoor heat exchanger temperature.
3.7
Heating Peak-cut Control
During heating operation, the indoor heat exchanger temperature determines the frequency
upper limit to prevent abnormal high pressure.
The operating frequency limitation is judged with the indoor heat exchanger temperature.
