Note
The relays are semiconductor relays for pump
speed control.
The minimum pump speed must be set to 100%
when auxiliary relays or valves are connected.

WARNING!
Î Always disconnect the con-
troller from power supply
before opening the housing!
The unit must only be located in dry interior locations. It
is not suitable for installation in hazardous locations and
should not be placed close to any electromagnetic fields. The
controller must additionally be supplied from a double pole
switch with contact gap of at least 3 mm. Please pay atten-
tion to separate routing of sensor cables and mains cables.
1. Unscrew the cross-head screw from the cover and re-
move it along with the cover from the housing.
2. Mark the upper fastening point on the wall and drill and
fasten the enclosed wall plug and screw leaving the head
protruding.
3. Hang the housing from the upper fastening point and
mark the lower fastening point through the hole in the
terminal box (centres 130 mm). Drill and insert the lower
wall plug.
4. Hang the housing from the upper fastening point and
tighten lower fastening screw.
The power supply to the controller must be carried out via
an external power switch (last step!) and the supply voltage
must be 100 ... 240 V~ (50 ... 60 Hz). Flexible cables must be
attached to the housing with the enclosed strain relief and
the corresponding screws.
The controller is equipped with 2 relays to which loads
such as pumps, valves etc. can be connected:
• Relay 1
18 = conductor R1
17 = neutral conductor N
13 = ground terminal
• Relay 2
16 = conductor R2
15 = neutral conductor N
14 = ground terminal
The temperature sensors (S1 to S4) have to be con-
nected to the following terminals (either 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 TRF)
The mains connection is at the terminals:
19 = neutral conductor N
20 = conductor L
12 = ground terminal
