not interfere with the manual change.
When selecting extended manual fan control, the fan display changes between AUTO (bus value),
N (Night) and M1 to M6. The night fan speed is specified via Modbus register 135,
the AUTO speed with the display 'A' via register 111 and the display of the actual speed via register 134.
