drilling template). The housing base is fitted with raised supports.
Screws: Max. diameter 3.5 mm, min. length 38 mm

When mounting note the following:
 The controller should not be freely accessible after mounting. It must be mounted in
a cabinet or behind a cover that can only be opened / removed with a key or a tool.
 Ensure adequate air circulation to dissipate
heat generated during operation.
 Easy access is required for service personnel
 Local installation regulations must be observed.
Mounting instructions and a drilling template are printed on the controller packaging.
The RXB2... room controllers are commissioned with either the ETS3 Professional or
the Synco ACS tool
 via the RS232-KNX / EIB interface, or
 via the USB-KNX / EIB interface (OCI700),
or with the HandyTool" via PPS2
The definitive application and the controller's location are handwritten in the labeling
fields "Appl." and "Loc" in the commissioning stage.
A special test mode (ETS3 Professional or "HandyTool") is available for operation of
the outputs. Further, if the digital inputs have been activated, they can be interrogated.
