8-bit scene). RDF301.50H only: • Four buttons for Hotel applications to control via KNX S-mode. Same functions as RDF301.50, but with dedicated button labels for hotel applications: Make Up Room (MUR), Do Not Disturb (DND). Applications The thermostats support the following applications, which can be configured using the DIP-switches on the inner side of the thermostat's front panel or a commissio- ning tool.

Use ETS to assign the KNX group addresses of the RDF communication objects. Assign KNX group addresses Switching groups RDF301.50 and RDF301.50H have 2 switching groups with a pair of buttons each, RDF301.50… only which must be configured via ETS. The switching groups only work on S-mode. KNX serial number Each device has a unique KNX serial number inside the front panel.
