1.2 Electrical connection
The power supply to the controller must only be made by
an external power supply switch and the line voltage must
be 120 VAC (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 relays, to which
the consumers (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) will be
connected to the following terminals independently of the
polarity:
1 / 2 = Sensor 1 (e.g. Sensor collector 1)
3 / 4 = Sensor 2 (e.g. Sensor tank 1)
5 / 6 = Sensor 3 (e.g. Sensor collector 2)
7 / 8 = Sensor 4 (e.g. Sensor tank 2)
The power supply is effected to the clamps:
19 = Neutral Conductor N
20 = Line Conductor L
12 = Ground Clamp

Electrostatic discharge can lead to damages of elec-
tronic components!
Dangerous voltage on contact!
The unit is designed for indoor installation only. It is not
suitable for installation in hazardous locations and should not
be sited near to any electromagnetic field. The controller
must installed in accordance with all electrical regulations.
These regulations vary from region to region. Please contact
the appropriate agency in your area if unclear on this.
Wall Mounting Instructions
1. Unscrew the cross-recessed screw of the cover and
remove it from the housing.
2. Mark the upper fastening point on the wall and mount
the enclosed dowel and screw.
3. Hang up the housing at the upper fastening point and
mark the lower fastening point on the wall. The distance
between the 2 mounting holes is 130 mm.
4. Fasten the housing at its lower point..
Warning!
Switch-off power supply before
opening the housing.
