Note
If Grundfos Direct Sensors™ are used, connect GND of the combined
inputs (K1 / K2) to PE.
Note
Install the flow rate sensor into the return.
Connect the V40 flowmeter to the terminals 1 and GND of the corresponding
combined input (either polarity).
The S0 outputs are used for issuing the energy quantity:
S0-1: HQM 1
S0-2: HQM 2

The device 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 terminals:
Neutral conductor
N
Conductor L
Protective earth conductor
⏚
Note
For more details about the commissioning procedure see page 13.
2.3 Data communication / bus
The device is equipped with a VBus
®
for data transfer and energy supply to ex-
ternal modules. The connection is to be carried out at the terminals marked VBus
(any polarity).
One or more VBus
®
modules can be connected via this data bus.
Note
If several VBus
®
accessories are used with a cascade, a VBus
®
-Repeater may
be required. For more information about cascade operation, see page 18.
