1. Select necessary programme/hydraulics.
2. Open controller casing (“C.1. Wall installa-
tion” on page 8).
3. Strip cables by 55 mm, insert, fi t the strain
relief devices, strip the last 8-9 mm of the
wires. (Fig. C.2.1.).
4. Open the terminals using a suitable
screwdriver (Fig. C.2.1.) and make electri-
cal connections on the controller.
5. Refi t terminal connection cover and fasten
screw.
6. Switch on mains voltage and place cont-
roller in operation.

Installation
C.3. Installing the water detectors
The controller operates with water detectors as an additional security measure to prevent water
damage.
The water detector cables must be routed separately from mains voltage cables and
must not, for example, be routed in the same cable duct!
If desired the sensor cables can be extended to a maximum of 30 m using a cable with
a cross-section of at least 0.75 mm². Make sure that there is no contact resistance!
Position the sensor precisely in the area to be measured!
Only use appropriate water detectors for the respective and authorised fi eld of
application.
The polarity of the water detector is irrelevant. Position the water detector on the fl oor,
where it is expected for water to collect. In this case all three contact feet must be wet-
ted. The contact feet should always be blank, with no “adhesions”/corrosion/incrusta-
tions. Normally, the contact feet should be placed on a dry surface.
