NO. Item
Fan speed 1. The fan operates in one of the four speed modes of "HIGH (HH)", "MED
(H)", "LOW (L)" and "AUTO" on the basis of a command issued via the
control
remote controller. (Concealed duct high static pressure type: HH only)
2. In AUTO fan speed mode, the air speed changes according to the
difference between Ta and Ts.

• When TC2 ≥ 60 °C, the fan speed is raised by one step.
3. If the air conditioner goes thermo OFF during heating operation, the fan
speed drops down to LL (breeze).
