3. Current release control
The output frequency and the output voltage are controlled by AC current value detected by current transformer
on the outdoor P.C. board so that input current of the inverter does not exceed the specified value.

4-1. Cooling fan control
1) An outdoor fan is controlled by TL sensor, TO sensor and compressor frequency. An outdoor fan is
controlled at 1-tap interval of DC fan control.
2) At the start time, the fan is fixed for 60 seconds only with the maximum fan tap corresponded to the zone
in the following table but it is controlled with TL sensor temperature after then.
+
1 tap / 20 sec (Up to the maximum
rotational frequency of each zone)
Rotational frequency hold
– 1 tap / 20 sec
(Up to the minimum rotational
frequency of each zone)
