When the outdoor air temperature (TH3) is 13ºC or 17ºC or higher continues for 30 seconds
while the compressor command speed other than 0 rps.
a)
b)
c)
Taking the upper limit of compressor command speed range at 65 rps or 35 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 20 rps or 25 rps and even if the calculated result becomes
lower than that after fuzzy calculation, the speed is kept to 20 rps or 25 rps. However, when the
thermo becomes
OFF, the speed is reduced to 0 prs.
