Fault rectification
In order to flush, movement must
•
have been detected (by fluid flo-
wing away). The duration of mo-
vement detection is adjustable (mi-
nimum usage duration 3 to 9 se-
conds). Check the setting for mini-
mum usage duration.
For a period of approx. 30 se-
•
conds after a flush, the sensor ope-
rates at reduced sensitivity, in or-
der to prevent false triggering by
small amounts of residual flush
water. During this period, the set
minimum usage duration is also
automatically increased by approx.
2 seconds.
Make sure that the hybrid mode is
•
deactivated. If the hybrid mode is
activated, the system flushes only
at stipulated fixed intervals.
