If the RLS 1 WR single control unit setting 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 system. The actuator’s potential-free contacts must be configured for switching 12 VDC.
