A2 CDV unit control
If the setting “ simple control unit ” is changed to “ digital ”,
the controlled domestic ventilation unit can be controlled
using a switching actuator (e.g. KNX). This allows the
controlled domestic ventilation unit to be integrated in
a building control technology. The actuator’s potential-free
contacts must be configured for switching 12 VDC.
