Receivers with PPS2 interface Type RXZ90.1
Compatibility
The RXZ90.1 receiver, in conjunction with wireless sensors, is suitable for use with all
room controllers with a PPS2 room unit interface (e.g. the DESIGO RX controllers).
System expansion
Up to a maximum of
5 room units
may be allocated to one receiver (see
Commissioning and establishing communication).
If several room units are used, the
receiver determines the average of the temperature values received. The average
room temperature is then transmitted to the room controller.
In the case of room units with setpoint adjusters (QAX91.1), only one may be
assigned to each receiver. Other room units with setpoint adjusters are treated as
QAX90.1 units (room temperature only).
