Depending on the product version, cables are already connected to the device. If
that is not the case, please proceed as follows:
The controller is equipped with 5 relays in total to which loads such as pumps,
valves, etc. can be connected:
Relays 1 and 4 are electromechanical relays.
Relays 2 and 3 are semiconductor relays, designed for pump speed control.
Conductor R1 … R4
Neutral conductor N (common terminal block)
Protective earth conductor
⏚
(common terminal block)
Relay 5 is a potential-free relay:
The connection to R5 can be made with either polarity.
The connector marked 24 V is used for connecting the actuator for the trans-
mission station.
The temperature sensors (S1 to S8) have to be connected to the terminals
S1 … S8 and GND (either polarity).
The terminal S9 can be used as an impulse input for an impulse flow rate sensor
or as an input for a flow switch.
An impulse flow rate sensor can be connected to the terminals S9 / V40 and GND
(either polarity).
Connect the irradiation sensor to the terminals CS10 and GND with correct
polarity. To do so, connect the cable marked GND to the GND common terminal
block, the cable marked CS to the terminal marked CS10.
In the menu, the irradiation sensor will be indicated as CS10.
The connector marked PWM / 0-10 V contains the 2 PWM / 0-10 V control signal
outputs for high-efficiency pumps or the 0-10 V boiler control respectively.

In the In-/Outputs menu, relays can be allocated to the PWM outputs.
Connect the digital Grundfos Direct Sensors™ to the VFD and RPD inputs.
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 mains connection is to be made at the following terminals:
Neutral conductor N
Conductor L
Protective earth conductor
⏚
(common terminal block)
WARNING! Electric shock!
L' is a fused contact permanently carrying voltage.
Î
Always disconnect the device from power supply be-
fore opening the housing!
Conductor L' (L' is not connected with the mains cable. L' is a fused contact
permanently carrying voltage.)
Note
For more details about the commissioning procedure see page 13.
