Do not use the device if it is visibly damaged!
The controller is equipped with 14 relays in total to which loads such as pumps,
valves, etc. can be connected:
Relays 1 ... 13 are semiconductor relays, designed for pump speed control:
Conductor R1 ... R13
Neutral conductor N (common terminal block)
Protective earth conductor ⏚ (common terminal block)
Relay 14 is a potential-free relay:
R14-A = normally open contact
R14-M = centre contact
R14-R = normally closed contact
Depending on the product version, mains cables and sensor cables are already con-
nected to the device. If that is not the case, please proceed as follows:
The temperature sensors (S1 to S12) have to be connected to the terminals S1
to S12 and GND (either polarity).
