10.5 Password-protected unit parameters
The unit leaves the factory with the unit parameters set by default to values capable of fulfilling most instal-
lation situations. For detailed customisation of the system, however, it is possible to make changes; a list of
all the unit parameters, with the available settings, is given below.
Depending on the configuration of the unit, some parameters are visible and others are not.
