8.5.7. Anti-Dew Formation Control
• Purpose is to prevent dew formation on indoor unit air discharge area.
• When room temperature is constant (±1°C) the following conditions occur for 30 minutes continuously, anti-dew formation will
activate:
− Remote Control setting temperature is less than 25°C.
− Compressor is on.
− Cooling operation mode.
− Indoor Fan motor operate at Low fan speed or QLo.
• This control is cancelled immediately when above condition is changed.
• Anti-Dew formation is control by:
1. Increasing Air Flow Volume
a. Lo fan speed
Lo fan speed is changed to Lo+ after 30 min to prevent dew formation.
b. QLo fan speed
Dew formation may occurs at QLo cool, therefore QLo cool is operated only 1 hr 30 min (1 hr QLo, 30 min QLo +100
rpm). After that, it operates at QLo +180rpm (However Quiet LED remains on).
2. Norrowing
Vertical Airflow Direction
− During Anti-dew condensation prevention, Airflow Direction Auto-control angle change from 10° - 38° to 10° - 27° under
Cooling and Soft Dry operation mode.
