When the indoor fan control is set to Auto, the fan speed is automatically selected according
to the mode of operation, set temperature and room temperature.
In cool mode, choosing Auto Fan will result in the following automatic fan speed selection:
Room Temperature
< Set pt-3°C = Set pt-3°C = Set pt. = Set pt+3°C > Set pt+3°C
Indoor Fan Speed
LOW LOW * HIGH HIGH
* Maintain current fan speed
Therefore, if the temperature set point is 20°C when cool mode is first entered in a room at
23°C, the indoor fan speed will be automatically HIGH.
The Indoor Fan Speed still remains at HIGH when the room temperature later lowers to 20°C.
When the room temperature falls further to 17°C, indoor fan speed changes to LOW.
If the room temperature rises to 20°C again, the indoor fan will still run at LOW speed.
Indoor fan speed will not be changed to HIGH unless the room temperature rises further to
23°C.
In dry mode, the indoor fan constantly runs at low speed. The Auto Fan function is not
available:
Room Temperature
< Set pt-1°C = Set pt-1°C = Set pt. = Set pt+1°C > Set pt+1°C
Indoor Fan Speed
LOW LOW LOW LOW LOW
In heat mode (Heat Pump Unit only), indoor fan speed is controlled as follows:
Room Temperature
< Set pt-3°C = Set pt-3°C = Set pt. = Set pt+3°C > Set pt+3°C
Indoor Fan Speed
HIGH HIGH * LOW LOW
* Maintain current fan speed
For example, if the set temperature is 20°C when heat mode is entered in a room at 17°C, the
indoor fan speed will be automatically HIGH.
The indoor fan speed still remains at HIGH when room temperature later rises to 20°C.
When the room temperature rises further to 23°C, the indoor fan speed is changed to LOW.
If the room temperature subsequently falls to 20°C again, the indoor fan will still run at LOW
speed. The indoor fan speed will not be changed to HIGH unless the room temperature dips
further to 17°C.
When Sleep function is selected in manual operation, indoor fan speed will be fixed at LOW
until the air-con is eventually turned off by sleep function.
