THE LEVEL OF HYSTERESIS
The level of hysteresis indicates the amount of increase
in the flow above the alarm level required to stop the
alarm automatically. The default setting is 0,3 l/min. In
the default setting mode, the flow alarm will be activated
when the flow decreases below 0,5 l/min for more
than five seconds. It will be deactivated when the flow
increases by more than 0,8 l/min.
4.3 Changing the default settings
To change the default settings, open the plastic case of
the controller.
Turn the power off using the on/off switch prior to
opening the case!
Proceed with great caution!
Behind the controller's circuit card there are two
programming buttons that can be used to change the
default settings. See the picture.
