Meaning 1 byte
This parameter defines which status – Current fan speed or Required fan speed – is displayed.
What is current fan speed?
The Current fan speed is the speed at which the fan is actually operating.
What is required fan speed?
The Required fan speed is the fan speed which has to be reached, e.g. when the transition
and dwell times have elapsed.
The limitations are included in this observation, i.e. if a limitation allows only fan speed 2,
the fan is operating at fan speed 2, and, for example, a telegram to switch up is received,
the required fan speed remains at 2, as fan speed 3 cannot be reached due to the
limitation.
