3.8 Radio telegram
3.8.1 Normal operation
In normal operation STM 33x transmits telegram data according to the selected EEP
(EnOcean Equipment Profile).
For details please refer to the EnOcean Equipment Profiles 2.1 specification.

3.8.2 Teach-in telegram
In case of a wake-up via WAKE1 pin (LRN input) the module transmits a teach-in telegram.
If the manufacturer code is not set, the module transmits a normal telegram according to 3.8.1
with the difference that DI_3=0.
If a manufacturer code is set, this teach-in telegram contains special information as described
below.
With this special 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 sup-
ported by STM 33x. They have to be selected according to the availability of external occu-
pancy button and set point control by the method described in 3.7.2:
A5-02-05 Temperature sensor 0-40 °C (default)
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 2.1 specification.

3.9 Transmit timing
The setup of the transmission timing allows avoiding possible collisions with data packages
of other EnOcean transmitters as well as disturbances from the environment. With each
transmission cycle, 3 identical subtelegrams are transmitted within 40 ms. The transmis-
sion of a subtelegram lasts approximately 1.2 ms. The delay between the three transmis-
sion bursts is affected at random.
