room occupants. When designing these stylish room units, the designers also paid
special attention to ergonomic factors.

In the conventional way, with standard room units for HVAC and electric switches to
control lighting and blinds
•
Wireless room units for HVAC, which can be located anywhere in the room
•
KNX switches and KNX actuators from third-party manufacturers
