When the DEVIreg™ 850 cannot communicate with a sensor, the DEVIreg™ 850 reports
the error: “Errors detected!”. The DEVIreg™ 850 does not rely on malfunctioning sen-
sors, and therefore the DEVIreg™ 850 makes the sensor passive. The passive sensor is
no longer used for ice and snow detection - not even after a power cycle.
If the malfunctioning is caused by problems with the wiring, the failure can be
xed, and the sensor can be reactivated.
If the malfunctioning is caused by an error prone sensor, the error can be cor-
rected by replacing the error prone sensor with a new sensor.
It is not possible to delete a passive sensor in a system. Passive sensors will
remain in the systems until they are replaced with new sensors. The only way to
delete a passive sensor (other than replacing it), is to make a Master Reset and
reinstall the DEVIreg™ 850 (please refer to chapter: General use).
