Minimum usage
duration set incorrectly
•
In order to flush, movement
must have been detected (by fluid
flowing away). The duration of
movement detection is adjustable
(minimum usage duration 3 to 9
seconds). Check the setting for
minimum usage duration.
•
For a period of approx. 30
seconds after a flush, the sensor
operates at reduced sensitivity, in
order 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.
Flush system in the
wrong mode
•
Make sure that the hybrid mode is
deactivated. If the hybrid mode is
activated, the system flushes only
at stipulated fixed intervals.
