2.2 Electrical connection
Note:
Connecting the device to the power supply must always be the last step
of the installation!
The controller is equipped with 5 relays in total to which loads such as pumps,
valves, etc. can be connected:
Relays 1 ... 4 are semiconductor relays, designed for pump speed control.
Conductor R1... R4
Neutral conductor N (common terminal block)
Protective earth conductor PE
⏚
(common terminal block)
Relay 5 is a potential-free relay:
Connections to the R5 terminals can be made with either polarity.
WARNING!
ESD damage!
Electrostatic discharge can lead to damage to electronic com-
ponents!
Î
Take care to discharge properly before touching
the inside of the device! To do so, touch a grounded
surface such as a radiator or tap!
Note:
The pump speed must be set to 100 % when non-speed-controlled devices
such as valves are connected.
WARNING!
Electric shock!
Upon opening the housing, live parts are exposed!
Î
Always disconnect the controller from power supply
before opening the housing!
Note
For more details about the initial commissioning procedure see page 13.
Depending on the product version, mains cables and sensor cables are already
connected to the device. If that is not the case, please proceed as follows:
Temperature sensors (S1 to S9) have to be connected to the terminals S1... S9 and
GND (either polarity).
