Radio telegram
3.10.1
Default configuration and standard mode
In default configuration and standard mode STM 33x transmits a radio telegram according
to EnOcean Equipment Profile A5-02-05 (Temperature sensor 0-40 °C) as defined in the
EnOcean Equipment Profiles (EEP) specification.
In standard mode STM 33x can be configured to following EEPs:
STM 33x: A5-02-05, A5-02-30, A5-10-05, A5-10-03
STM 33x with HSM 100 extension: A5-04-01, A5-10-10, A5-10-12
By pressing the LRN button 1 s in standard mode a 4BS teach-in telegram is transmitted.
After pressing the LRN button for 5 seconds a signal telegram (data: 0x0E) will be sent and
the module enters the transport mode. For details see EnOcean Alliance EEP specifica-
tion(Stepcode >=DE). In this mode the module does not send telegrams.
For details please refer to the EnOcean Equipment Profiles specification.
