7-4. 4) 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
Hydro side (Hydro unit) control part.
For sensing the true outside temperature, fan is operated without compressor operation.
* 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.

4-1) 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 (401, 601), TG (801, 1101). (TG: temperature converted from
PD)
