Receivers with PPS2 interface
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).
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).

breaking out the perforated cable entry guide.
Basically the unit comprises the housing and the mounting plate. These can be
snapped together and apart.
The housing accommodates a printed circuit board and a tool socket (RJ45).
The housing and mounting plate are plastic.
