Thereafter, the high-pressure is monitoring at a set time interval and the fan speed is changed by the following conditions.
(Condition which lowers the fan speed)
High-pressure 3.30MPa and heat sink temperature 80°C
(Condition which raises the fan speed)
High-pressure saturation 3.20MPa or heat sink temperature 85°C
The initial speed of the first boot outdoor unit is detected by outdoor air temperature sensor value (TAOUT).
