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.

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.
3. If the air conditioner goes
thermostat
OFF during heating operation, the
fan
speed drops down to LL (breeze).
