Warning!
Switch-off power supply before
opening the housing.
The unit must only be located internally. It is not
suitable for installation in hazardous locations
and should not be exposed to any electromag-
netic field. The controller must additionally be
equipped with an all-polar gap of at least 3 mm
or with a gap according to the valid installaton
regulations, e.g. LS-switches or fuses. Please
pay attention to a separate laying of the cable
lines and installation of ac power supply.
1. Unscrew the cross-recessed screw of the cov-
er and remove it from the housing.
2. Mark the upper fastening point on the under-
ground and premount the enclosed dowel and
screw.
3. Hang up the housing at the upper fastening
point and mark the lower fastening point on
the underground (hole pitch 130 mm), after-
wards put the lower dowel.
4. Fasten the housing at the underground.
The power supply of the controller must only be
made by an external power supply switch (last
step of installation!) and the line voltage must
be 100 ... 240 Volt (50 ... 60 Hz). Flexible lines
are to be fixed at the housing by enclosed strain
relief supports and screws.
The controller is equipped with 2 standard re-
lays, to which the consumers e.g. pumps,
valves etc. can be connected:
• Relay 1
18 = conductor R1
17 = neutral conductor N
13 = protective earth conductor
• Relay 2
16 = conductor R2
15 = neutral conductor N
14 = protective earth conductor
The temperature sensors (S1 up to S4) have
to be connected to the following terminals inde-
pendently from the polarity:
1 / 2 = Sensor 1 (e.g. Sensor collector 1)
3 / 4 = Sensor 2 (e.g. Sensor store 1)
5 / 6 = Sensor 3 (e.g. Sensor collector 2)
7 / 8 = Sensor 4 (e.g. Sensor store 2)
