Operation
5.8.4 Connection of a leak sensor
A leak sensor is available as an option (see
chapter 9.5 “Accessories”). It comprises
2 stainless steel electrodes, that are located
approximately 2 mm above the floor. Trig-
gering takes place if the electrodes are con-
nected by a water film. Water conductivity
must exceed 100 µS/cm.
5.9 Potential-free signal relay
In the following cases a message is dis-
played by a potential-free signal relay:
– In the event of a water softening system
fault indication
– in the event of power loss (only with set-
ting 'NCC')
– If a low salt condition exists
– In the event of a leakage alarm
chapter 2.2 “Indication of particular dan-
gers” must be observed without fail!
Adhere to the maximum switching current
and maximum voltage (see chapter 2.2.1
“Electrical devices/installations”)!
The contacts of the potential-free relay are
shown in the zero-current state in fig. 12.
Setting the switching function:
Press the key 1x and then

2x. The
display shows the following:
Press key <OK> 1x and then key

as often
as necessary, until the display indicates the
following:
Press the <OK> key. The display shows the
following:
Press key

or

to change between <Nor-
mally closed> and <Normally open>.
The chosen setting is saved by pressing
<OK>.
5.10 Integration of the water soften-
ing system in building control
systems
The water softening system can be integrat-
ed via the potential-free relay into a building
control system (e.g. EIB, LCN or LON).
For example, the potential-free relay is con-
nected to a binary bus coupler. This allows a
fault indication to be forwarded to the build-
ing control system.
5.11 Connectivity module (acces-
sory)
A retrofittable connectivity module is used to
connect the water softening system via a
LAN connection to the home network and
the Internet (see chapter 9.5 “Accessories”).
One connectivity module is required for
each individual softener. Each device is de-
tected individually; i.e. the softener appears
twice in the app.
Using the “JU Control” iOS/Android app,
worldwide access to comprehensive infor-
mation, automated messages and functions
of the water softening system is possible.
Prior to electrical installation, pull the
power supply unit out of the socket!
