Building Technologies Division
Heating, ventilation and air-conditioning – room temperature control
Technical specications
Room temperature controllers with detached operation
Fields of application
The scope of RXB is defined by the preprogrammed application software. The following pages provide an overview of the options and the corres-
ponding devices, divided into different areas of application. The devices are supplied preprogrammed with the applications. The required applica-
tion can be selected by means of the ETS, Synco™ tool or the Handy tool QAX34.3.
Due to the fact that the applications are predefined, engineering simply involves the definition of a small number of parameters, e. g.:
• PWM or 3-position control of the valves and actuators
• Temperature setpoints
• Manual or automatic fan control
• Room operating units QAX3.., QAX84.1 (PPS2 interface), or UP2... / QMX3.P34 via KNX
