a) Protective control
i) When the outdoor air temperature (Tho-A) is 40°C or higher and the outdoor heat exchanger temperature (Tho-R)
exceeds setting value, the compressor speed (frequency) is controlled in order to suppress the rise of high
pressure.
ii) The control value A is updated to an optimum value automatically according to the operating conditions.
Control value A
54-60°C
Outdoor heat exchanger temperature (°C)

Reset
Reduce compressor
speed at every 1minute
b) Anomalous stop control
i) If the outdoor heat exchanger temperature (Tho-R) exceeds the setting value, the compressor stops.
ii) When the outdoor heat exchanger temperature anomaly is detected 5 times within 60 minutes, or 60 minutes
continuously including the time of compressor stopping, cooling overload error is displayed and E35 is recorded
in the Error Log and it enters the anomalous stop mode.

c) Reset of anomalous stop mode
When the outdoor heat exchanger temperature drops to the reset value of 51°C or lower, it becomes possible to restart
from the control.
b) Anomalous stop control
i) If the outdoor heat exchanger temperature (Tho-R) exceeds the setting value, the compressor stop.
ii) Whe n the outdoor heat exchanger temperature anomaly is detected 5times within 60 minutes, or 60 minutes
continuously including the time of compressor stopping, coolinf overload error is displayed and E35 is recorded
in the Error Log and it enters the anomalous stop mode.
