Different fan
speeds
The table below explains the meaning of L, H and HH fan speed.
L-tap starting
compensation
When the outdoor fan is operated from OFF to L-tap, the fan motor does not turn, because of lack of
starting torque. To avoid this, the fan motor operates at H-tap for the first 5 s after start-up, before
changing to L-tap.
Used input
The fan starting control in cooling or dry keep mode uses the following inputs:
