5) Outdoor fan control

 

 

 

 

 

 

 

 

 

Outdoor unit

The outdoor side control part controls the number of fan motor rotations by receiving an operation instruction from the

control

indoor side (Hydro unit) control part.

 

 

 

 

 

 

 

 

* Although the fan motor is a DC motor, which has non-step variable numbers of rotations, it is limited to some steps for convenience of

 

 

 

control.

5-1) Cooling fan control

The TL sensor, TO sensor and operation frequency control the outdoor fan. The control is performed by 1 tap of the DC fan control (14 taps).

For 60 seconds after the start, the maximum fan tap for each zone that is shown in the following table is fixed. After that, the fan is controlled according to the TL sensor temperature.
