The device is in normal operation. After a
short time the current water level is display-
ed in cm. The green LED for normal opera-
tion is lit. The device is running with the de-
fault factory settings. These are shown in
the table "5.4 Default factory settings"
7.2 Normal operation:
In normal operation, the switching device
compares the water level in the tank with
the set switching points. If there is sufficient
water in the rainwater tank (water level
above the USP) the system runs in rainwa-
ter mode, i.e. when a fixture (i.e. toilet, fau-
cet) connected to the service water system
is opened, rainwater is pumped into the
pipe network. If the water level falls below
the USP, the drinking water top-up is auto-
matically activated until the water level has
reached the OSP. Activation of the drinking
water top-up is indicated by the orange drin-
king water top-up LED.
7.3 Manual drinking water top-up
(TWvH)
The "T" button can be used to switch on
drinking water top-up (TWvH). TWvH auto-
matically switches off after a defined time.
The TWvH time is stored in set point E02
and can be changed at any time. During
TWvH the remaining time in minutes ap-
pears in the display. The decimal points of
the display flicker and the orange drinking
water top-up LED is lit. The TWvH can be
switched off manually at any time.
