Temperature values are transmitted in both raw and corrected temperature formats.
Unsuccessful radio communication attempts are If it has been 30 minutes or more since communication from the gateway has been received (Join Request success, Downlink from user, ACK response), then the device requests an Acknowledgement of its next Uplink. An ACK request without an ACK response is reported by status bit RCE“RCE”. After 6 3 consecutive unsuccessful radio communication attempts (acknowledge from the gateway)ACK requests, the actuator automatically switches to the safety mode and safety values “Rejoin”. In this situation, the actuator switches to Safety Mode and Safety Value as specified by the user. In this situation, the radio communication period is increased to once every hour, and attempts to rejoin the gateway. It sends a gateway Join Request at the frequency: 10 seconds, 10 seconds, 10 seconds, 2 minutes, then 1 hour until rejoined.
The actuator generates the required electrical energy for operation by means of a built-in thermoelectric generator (TEG) and therefore operates maintenance-free.
