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
Connecting the device to the power supply must always be the last step
of the installation!
Note
It must be possible to disconnect the device from the mains at any time.
Î Install the mains plug such that it is accessible at any time.
Î If this is not possible, install a switch that can be accessed.
If the mains cable is damaged, it must be replaced by a special connection
cable which is available from the manufacturer or its customer service.
Do not use the device if it is visibly damaged!

The controller is supplied with power via a mains cable. The power supply of the
device must be 100 … 240 V~ (50 … 60 Hz).
The controller is equipped with 1 semiconductor relay to which a load such as
a pump, a valve, etc. can be connected:
17 Protective conductor ⏚
18 Neutral conductor N
19 Conductor R1
The controller is equipped with 2 high-current relays for connecting an electric
immersion heater of up to 3 kW:
16 Protective conductor ⏚
23 Mains conductor
22 Conductor electric immersion heater
21 Neutral conductor mains
20 Neutral conductor electric immersion heater
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:
Connect the temperature sensors (S1 to S5) to the corresponding terminals
with either polarity:
1/2 Sensor 1 (collector sensor)
3/4 Sensor 2 (store sensor base)
5/6 Sensor 3 (store sensor top)
7/8 Sensor 4 (return sensor)
