Fan speed 1. The fan operates in one of the four speed modes of "HIGH (HH)", "MED (H)",
control "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.
• In AUTO fan speed mode, the fan speed remains the same for 3 minutes each
• At the beginning of cooling operation, a higher speed (steeper downward
• As long as the temperature difference remains on a boundary line, the fan speed

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