Notes (1) When the outdoor heat exchanger temperature is in the range of B-C ºC, the speed is reduced by 8 rps at each 20 seconds.
(2) When the temperature is C ºC or higher, the compressor is stopped.
(3) When the outdoor heat exchanger temperature is in the range of A-B ºC, if the compressor 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.

1) It controls the upper and lower limit values for the compressor speed according to the following table.
2) It checks the outdoor temperature (TH2) once every hour to judge the operation range.
When either of the following condition is satisfied.
1) The outdoor air temperature (TH2) is D°C or higher.
2) The compressor speed is 0 rps.

When the indoor heat exchanger temperature is in the range of A-B °C, if the compressor speed is been maintained and the operation has continued for more
than 20 seconds at the same speed, it returns to the normal heating operation.
