Siemens RDF301 Quick Start Guide

9 / 14
Siemens RDF301. / RDF301.50 / RDF600KN CE1N3171en
Building Technologies Semi flush-mount room thermostats with KNX communications 2012.10-04
Use ETS to assign the KNX group addresses of the RDF communication objects.
RDF301.50 has 2 switching groups with a pair of buttons each, which must be
configured via ETS. The switching groups only work on S-mode.
Each device has a unique KNX serial number inside the front panel. An additional
sticker with the same KNX serial number is enclosed in the packaging box. This
sticker is intended for installers for documentation purposes.
