1 Introduction
The unit provides the connection between the home
ventilation unit and the KNX building automation
infrastructure. The unit can be combined with the
home ventilation unit ComfoAir Q, Comfort Vent Q
or the AERISnext. As a result, one ventilation unit
can be controlled and monitored by KNX devices via
the unit. Additionally, the unit allows basic control
over an optionally connected ComfoCool and
ComfoHood.
