3. Current release control

The output frequency and the output voltage are controlled by AC current value detected by T20 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 operation frequency. An outdoor fan is con-

trolled 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.

rotational frequency of each zone)
