The controller is equipped with 5 relays in total to which
loads, such as pumps, valves and auxiliary relays can be
connected:
• Relays R1 to R4 are electromechanical relays:
R1 ... R4 = normally open R1 to R4
N = neutral conductor N (common terminal block)
PE = protective conductor PE (common terminal
block)
• Relay R5 is a potential-free relay with changeover
contact:
R5-M = center contact
R5-A = normally open
N
R5-R = normally closed
N = neutral conductor N (common terminal block)
PE = protective conductor PE (common terminal
block)

The controller is equipped with the RESOL VBus
transfer. The connection is carried out at the two terminals
marked "VBus " (either polarity).

The power supply to the controller must be carried out via
an external power switch (last step!) and the supply voltage
must be 220 ... 240 V~ (50 ... 60 Hz). Flexible cables must
be attached to the housing with the enclosed strain relief
and the corresponding screws or be run into the controller
housing in a cable conduit.
