Thereafter, the high-pressure is monitoring at a set time interval and the fan speed is changed by the following conditions.
Other outdoor units are normally operated at fan step 16.
(Condition which lowers the fan speed)
High-pressure 3.30MPa and heat sink temperature 75°C
(Condition which raises the fan speed)
High-pressure saturation 3.20MPa or heat sink temperature 80°C
The initial speed of the first boot outdoor unit is detected by outdoor air temperature sensor value (TAOUT).

duration time ( sec )
When switched from normal fan step to intermittent fan step, always start from 300rpm/7sec.
When there was a change during intermittent step 1-6, switching is performed at the time the current speed
duration time reaches time-up.
