To prevent the unauthorized writing of certain parameters, these will only be written if the correct password for
the necessary authorization has been entered at this point. After the password has been entered successfully,
the values in the holding registers are reset to 0x0000 to prevent third parties from reading out the password.
If a user forgets to reset the password, the write authorization will be automatically reset to "End customer"
after 4 minutes of inactivity.

Error
D -> F
F -> D
Setting the bit D -> F causes all the parameters of the data area (holding registers D100 - D17F) to be copied
to the factory setting area (holding registers D280 - D2FF).
"ebm-papst" authorization is required for setting this bit.
Setting the bit F -> D causes all the parameters of the factory setting (holding registers D280 - D2FF) to be
copied to the data area (holding registers D100 - D17F).
"Customer" authorization is sufficient for setting this bit.
On completion of copying, the bit is automatically reset by the fan.
If an error occurs during copying, the "Error" bit is set and copying is terminated
