6 Fan Mode Operation
With this mode, the indoor fan is turned on while CM and FMO stay off all the time. The user can
select between 3 speeds: HIGH, MEDIUM and LOW.
7 Auto Fan speed
With this option selected, the indoor fan speed changes automatically according to the compressor
speed as shown in the following graph

In heating, to prevent the supply of cool air, the FMI speed is setted as shown only if the indoor
coil temperature ICT ≥ 34°C ( see COLD DRAFT PREVENTION feature for details )
If RAT goes over SET POINT by 1°C or less, for 1 hour, FMI is forced to LOW. If after
1 hour, RAT is still over SPT, FMI and compressor switch off.
