Power supply is provided by a small solar cell, an external energy harvester, or an external
3 V battery. An energy storage is installed to bridge periods with no supply from the energy
harvester. The module provides a user configurable cyclic wake up.
After wake up the internal microcontroller reads the status of the temperature sensor and
optional set point dial. A radio telegram will be transmitted in case of a significant change
After wake up the internal microcontroller reads the status of the temperature sensor and
optional set point dial. A radio telegram will be transmitted in case of a significant change
of measured temperature or set point values or if the external occupancy button is pressed.
In case of no relevant input change a redundant retransmission signal is sent after a user
configurable number of wake-ups to announce all current values.
In case of no relevant input change a redundant retransmission signal is sent after a user

In addition to the cyclic wake-up, a wake up can be triggered externally using the input for
the occupancy button or the internal LRN button.

The firmware can be configured to use different EEPs according to the availability set point
dial and occupancy button.
