2 Intended use
The EnOcean wireless plug-in module can
be used to operate the ventilation unit with
optional EnOcean components (according to
EnOcean wireless standard). Once the plug-
in module has been installed, the EnOcean
wireless sensors and operating units can be
learnt via the comfort control unit, web server
or commissioning software (installer).
Read the safety instructions in the instal-
lation instructions for the ventilation unit
before connecting the EnOcean compo-
nent to the ventilation unit. Follow the
instructions.
