The radio interface is always deactivated at delivery. To activate the device, no
software is required.
Attention!
For zelsius C5 with LoRa interface, we recommend at first
to do the onboarding of the device on your respective IoT platform
by putting in the key information belonging to the device (DevEUI,
JoinEUI and AppKey) before activating the device as described below!
Only the activated sleep mode has to be finished: Devices that are in
sleep mode (Display: SLEEP 1) must be activated by at least five second press of the
button until the energy display appears or display "r. outlet" (see page 7).
In the case of variants with LoRa-interface it is possible to retrieve a diagnostic tele-
gram via the network server with the following data:
■
Heating or resp. and cooling energy
■
Volume
■
Average values of temperatures during transmitting interval (supply, return,
difference)
■
Maximum return temperature during transmitting interval
■
Average values for power and flow rate during transmitting interval
