Dry operation
PLFY EM PLFY FM PLFY
PCFY KM PKFY LM PKFY
The Dry mode is a dehumidifying mode in which the unit intermittently operates in a mild cooling mode.
During seasons when operating the unit in the Cooling mode tends to overcool the room, such as during the rainy
season, the Dry mode helps keep the room at a comfortable temperature by reducing the room temperature by a few
degrees centigrade.
*The unit cannot be operated in the Dry mode when the room temperature is below 18°C.
*The fan operates at low speed in the Dry mode. (When the user tries to change the fan speed, the fan speed display on the remote controller will change, but the selection will not
actually be reflected.)
Dual set point

PCFY KM PKFY LM PKFY
Normally, the desired room temperature is set to the same value for cooling and heating. However, the dual set point
function allows different temperatures to be set for cooling and heating. When operation switches from cooling to heating
or vice versa, the preset temperature changes accordingly.
External static pressure setting
