5 Fan speed
control
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 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.

• Control is identical in remote controller thermo and body thermo operation.
Speed modes shown in < > apply to cooling operation under AUTO air
conditioner operation mode.
• In AUTO fan speed mode, the fan speed remains the same for 3 minutes each
time a speed change occurs.
However, a speed change command issued via the remote controller can
override this, and the fan speed changes accordingly.
• At the beginning of cooling operation, a higher speed (steeper downward
temperature gradient) is chosen.
• As long as the temperature difference remains on a boundary line, the fan speed
stays the same.

Figures inside ( ) applies to remote controller thermo operation.
Figures outside ( ) applies to body thermo operation.
Speed modes shown in < > apply to heating operation under AUTO air conditioner
operation mode.
• In AUTO fan speed mode, the fan speed remains the same for 1 minute each
time a speed change occurs.
However, a speed change command issued via the remote controller can
override this, and the fan speed changes accordingly.
• At the beginning of heating operation, a higher speed (steeper upward
temperature gradient) is chosen.
• As long as the temperature difference remains on a boundary line, the fan speed
stays the same.
• When TC2 ≥ 60 °C, the fan speed is raised by one step.
