Use
The room units are used in rooms controlled by an individual room control system, to
measure the room temperature, and, in the case of the QAX31.1, to adjust the room
temperature setpoint.
They can also be used in conjunction with a Desigo PXC… automation station
The room units incorporate a socket for a commissioning and service tool or service
terminal. This tool socket provides access via the PPS2 interface or via a bus system
(e.g. L
