Setting Description Indicator
Home

at home.
Light on
Away

use when you are away from home for longer
periods of time. It is recommended to activate
the Away mode every time you leave home.
Flashes
quickly
Pause
Temporarily de-activates the setting that shuts
off water and sounds an alarm. Activate this
mode when you need an infinite amount of
water, i.e. for watering the lawn.
Flashes
slowly
You can deactivate Pause mode anytime by pressing the mode button. The system
will return to its previous mode of operation.
The unit can be configured so that the valve is kept closed in Away mode. If this
function is activated, no tightness test is performed. Instead, the unit continuously
measures the pressure and warns if the pressure in the system drops below 1 bar.
ALARM
The alarm indicator flashes during the warning and stays on during
the alarm. Press the Clear button briefly to silence the warning and
alarm sounds. Keep the Clear button pressed to clear the alarm.
The system shuts off water only in case of an alarm. Silence the alarm by briefly
pressing the Clear button and find the cause of the alarm. The water will start to
flow again only after the alarm has been cleared.
The device warns before sounding an alarm if a delay has been set. The alarm
must be manually cleared whereas warnings can be automatically cleared
through the system after the cause of the alarm has passed.
You can set a time frame when the system stays silent in order to guarantee
uninterrupted sleep. Alternatively, you can permanently disable the alarm sound
or only allow sounds during a warning/alarm.
