(2) When the temperature is 63ºC or higher, the compressor is stopped.
(3) When the outdoor heat exchanger temperature is in the range of A~CºC, if the compressor command speed is been maintained and the operation has
continued for more than 20 seconds at the same speed, it returns to the normal cooling operation.
(4)
Cooling low outdoor temperature protective control
(a)
Operating conditions:
When the outdoor air temperature (TH2) is 22ºC or lower continues for 20 seconds while the
compressor command speed is other than 0 rps.
(b)
Detail of operation:
1)
The lower limit of the compressor command speed is set to 45 (35) rps and even if the speed becomes lower than

2)
The upper limit of the compressor command speed is set to 60 (75) rps and even if the calculated result becomes
higher than that after fuzzy calculation, the speed is kept to 60 (75) rps.
