AC1, AC2, N 230 V leading signals only:
AC1: 230 V input, for example remote switches (start backwash
via remote switch)
Function: With a voltage of 230 V (t>3s), a backwash/rinse cycle
is started.
AC2: 230 V input, for example from an external filter control
Function: With a voltage of 230 V and when in the "Filter"
position, the pump switches on.

Parameter and battery
All parameters, the start time for the backwash/rinse cycles, the
filter time and the time, are buffered with a battery. The service life
of the battery depends on various factors (device without voltage
supply, temperature, etc.), however it should last a minimum of
5 years.
The status of the battery is shown in the display:
= Battery OK
= Replace battery (CR2032)
If the battery performance declines, a capacitor guarantees the
maintenance of data for a few minutes during a power cut or
battery replacement.
Changing the battery:
Push the battery out towards the front.
Insert the new battery. "+" pole is on top.
3.3.10 Level regulation
Optional level regulation is possible using a float switch (article
no. 271.6090.005, level switch with 10 m cable). This is
connected to the terminal points G and S1.
The contacts 11 and 14 are used as outputs for the magnetic
valve. As these are potential-free contacts, the magnetic valve's
supply voltage (230 V) must first be hooked on to 11 (bridge from
L on the supply terminal to 11). Then the switching contact 14 can
be led to the magnetic valve. See "Fig. 5" on page 28.
