USER MANUAL
Scavenger Transmitter Module
STM 330 / STM 331 STM 331U / STM 332U / STM 333U
(Stepcode DE and later)
3.10.2 Teach-in telegram
In case of a wake-up via WAKE1 pin (LRN button input) the module transmits a teach-in
telegram.

If the manufacturer code is not set, the module transmits a data telegram according to
3.10.1 with the difference that DI_3=0. See EnOcean Alliance EEP specification appendix
3.3 variant 1.

If a Manufacturer ID is set, this teach-in telegram contains special information as de-
scribed below EEP specification appendix variant 2. By default EnOcean Manufacturer ID
is set. Customer can configure their own ID.
With this teach-in telegram it is possible to identify the manufacturer of a device and the
function and type of a device. The following EnOcean Equipment Profiles are supported by
STM 33x. They have to be selected according to the availability of external occupancy but-
ton and set point control by the method described in 3.9.2. Profile can be set via program-
mer and DolphinStudio PC Software:

A5-02-05 Temperature sensor 0-40 °C (default)

A5-02-30 Temperature sensor -40 – 62,3 °C

A5-10-03 Temperature sensor 0-40 °C, set point control

A5-10-05 Temperature sensor 0-40 °C, set point, and occupancy control
If a HSM 100 module is plugged onto the connector in addition the following EEPs are sup-
ported:

A5-04-01 Temperature and humidity sensor 0-40 °C and 0-100% r.h.

A5-10-10 Temperature and humidity sensor 0-40 °C and 0-100% r.h.,
set point control, and occupancy control

A5-10-12 Temperature and humidity sensor 0-40 °C and 0-100% r.h., set point control
For details please refer to the EnOcean Equipment Profiles specification.

3.11 Secure radio telegram
The STM 3xy modules can operate in
secure mode; this means the communication is protected by
enhanced security features. Commisioning and mode change is described in chapter 3.1.
3.11.1 Enhances security telegram
In secure mode of STM 330 / STM 331 the payload content of the telegram is always pro-
tected with advanced security features. Normal operation telegram payload and also Teach-
in telegram payload are protected in the same way.
The security features used are defined by the Security Level format - SLF. This parameter
is set by default to following values (Stepcode >=DE):

24-bit RLC which starts from 0 at production

RLC sent explicitly

3-byte CMAC
