WARNING!
Electric shock!
Upon opening the housing, live
parts are exposed!
Î
Always disconnect the de-
vice from power supply be-
fore opening the housing!
Note:
For more details about the initial commis-
sioning procedure see page 11.
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:
The
temperature sensors
(S1 to S8) have to be
connected to the terminals S1 … S8 and GND (either
polarity).
The S9 terminal is an impulse input for an impulse
flowmeter or a flow switch.
An impulse flowmeter can be connected to the termi-
nals 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 contains the 2 PWM- /
0-10 V control signal outputs for high-efficiency
pumps.

4 = PWM output 2, control signal
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 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.

Always disconnect the de-
vice from power supply be-
fore opening the housing!

Data communication / Bus
The controller is equipped with an
S-Bus
or data
transfer with and energy supply to external modules.
The connection is carried out at the two terminals
marked
S-Bus
and
GND
(either polarity). One or
more S-Bus modules can be connected via this data
bus, such as:
• OVENTROP CS-BS Datalogger
• Regtronic EM Extension Module
