Please note:
The relays are semi-conductor-relays for pump speed
control - they need a minimum load of 20 W (power con-
sumption of the consumer) for faultless function. If auxiliary
relays, motor valves, etc. are connected, the condenser
which is enclosed in the mounting material, must be con-
nected parallely to the relevant relay output.
Attention: for connection of auxiliary relays or valves, the
minimum pump speed must be adjusted to 100 %.
Dangerous voltage on contact!
Electrostatic discharge can lead to dama-
ges of electronic components!

Installation / Electrical wiring
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 electroma-
gnetic fi eld. 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 cover
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), afterwards
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 fi xed at the housing by enclosed strain relief
supports and screws.
The controller is equipped with 2 standard relays,
to which the consumers e.g. pumps, valves etc.
can be connected:
• Relay 1
18 = conductor R1
17 = neutral conductor N
13 = ground clamp
• Relay 2
16 = conductor R2
15 = neutral conductor N
14 = ground clamp
The temperature sensors (S1 up to S4) have
to be connected to the following terminals
independently 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)
The power supply is effected to the clamps:
19 = neutral conductor N
20 = conductor L
12 = ground clamp
