Manual functional test
We recommend to do a manual functional test after completion of
installation or in case of fault.
At the start of the functional test, only the central LED emits light
(
„Function“ ). The following components are queried:
n
Magnet valve
n
Flow switch
n
Backflow sensor
Flushing with all four sections must take place correctly, without back-
flow and with indication that flowthrough is present.
Enable all four valves (= delivery state).
Check the proper connection of drinking water and wastewater.
Press the Test button and keep pressed until all four valve sections
are open (LED indication).
ð
The flowthrough indicator emits light, the backflow indicator
does not light up.
Release the Test button.
ð
The valves close automatically with a time delay.
Next, set the valves / flowthrough volume to the correct values.
