Depends on compressor speed
The lower limit of compressor speed is set to 25 or 30 or 40rps.
However, when the thermo OFF, the speed is reduced to 0 rps.
The outdoor fan is stepped up by 3 speed step. [Upper limit 8 th speed.]

Notes (1) When the outdoor heat exchanger temperature is in the range of P2-P3䉝, the speed is reduced by 8 rps at each 20 seconds.
(2) When the temperature is P3䉝㻌or higher, the compressor is stopped.
(3) When the outdoor heat exchanger temperature is in the range of P1-P2䉝, 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.
