Notes () When the indoor heat exchanger temperature is in the range of B-C ºC, the speed is reduced by rps at each 0 (0) seconds.
() When the indoor heat exchanger temperature is in the range of C-D ºC, the speed is reduced by rps at each 0 (0) seconds. When the temperature
is D ºC or higher continues for minute, the compressor is stopped.
() When the indoor heat exchanger temperature is in the range of A-B ºC, if the compressor command speed is been maintained and the operation has
continued for more than 0 (0) seconds at the same speed, it returns to the normal heating operation.
() Indoor blower retains the fan tap when it enters in the high pressure control. Outdoor blower is operated in accordance with the speed.
() Value in ( ) are for the model SRF0.

Taking the upper limit of compressor command speed range at 60 rps, if the output speed obtained with the fuzzy
calculation exceeds the upper limit, the upper limit value is maintained.
The lower limit of compressor command speed is set to 40 rps and even if the calculated result becomes lower than
that after fuzzy calculation, the speed is kept to 40 rps. However, when the
