DESIGO™ RX
Receiver with
PPS2 interface
For use with room controllers in the DESIGO RX range,
in conjunction with the QAX90.1 and QAX91.1 wireless room units
• Wireless acquisition of room temperature and setpoint adjustments
• For use only in conjunction with the QAX90.1/QAX91.1 wireless room units
(data sheet CA2N1643)
• Determines the average room temperature from several room units
• PPS2 interface to room controller
• Socket for commissioning and service tool, diagnostic plug or service
terminal
The RXZ90.1 is used for wireless reception of the room temperature (from the
QAX90.1) and the room temperature setpoint (from the QAX91.1), and for
transmission of this information to a room controller. Wireless range indoors: approx.
30m.
