Warning!
Switch-off mains supply before
opening the housing.
The unit must only be located indoors. It is not suitable
for installation in hazardous locations and should not be
sited near to any electromagnetic field.The controller must
additionally be equipped with an all-polar gap of at least 3 mm
or with a gap according to the relevant installaton regulations,
e.g. LS-switches or fuses. Please ensure that sensor cables
and AC power cables are kept well apart.
1. Unscrew the cross-head screw of the cover and remove
it from the housing.
2. Mark the upper fastening point on the wall and insert the
enclosed wall plug and screw.
3. Hang the housing at the upper fastening point and mark
the lower fastening point on the wall (hole pitch 130 mm),
afterwards put the lower wall plug.
4. Fix the housing on the wall.
The power supply to the controller must only be made by
an external mains switch (last step of installation!) and the
mains voltage must be 220 ... 240 Volt (50...60 Hz). Flexible
lines are to be fixed at the housing by enclosed cable clamps
and screws.
The controller is equipped with 2 relays to which the out-
puts e.g. pumps, valves etc. can be connected:
L
• Relay 1
20
18 = line R1
17 = neutral N
13 = earth terminal
• Relay 2
16 = line R2
15 = neutral N
14 = earth terminal
The temperature sensors (S1 up to S4) will be connected
to the following terminals regardless of 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 TSPO)
7 / 8 = Sensor 4 (e.g. Sensor TRL)
The power supply is connected to the terminals:
19 = neutral N
20 = Line L
12 = earth terminal
Electrostatic discharge can damage electronic com-
ponents!
Dangerous voltage on contact!
