"Saving sensors"
If "Yes" is set, the current
status of the sensor inputs
is saved (e.g after remov-
ing a sensor). This status is
then not recorded as a fault
when the sensors are
checked on a daily basis at
0:00 h.
"Save parameters"
If "Yes" is set, the current
parameter settings are
saved as new default set-
tings. The factory set-
tings are thus overrid-
den. This does not include
fields such as time and
date, programming unit,
wireless, service/special
operation, all time pro-
grams and metering func-
tions.
