Like the VR 90 remote control units, the VR 60 mixer
modules also communicate with the heating controller
via the eBUS. When installing, observe the same proce-
dure as for connecting the remote control units (see
Chap. 5.8.1).
The system structure can be seen in Fig. 5.16. Observe
the mixer module manual.

• Fasten the casing of the vrnetDIALOG to the mounting
panel of the operating console using the self-tapping
screws (1) and (2) from the accessory bag. For fixing,
see also the vrnetDIALOG manual.
• Pass the power supply cable present within the heat
pump (5) through the opening in the upper front clad-
ding and connect it to the vrnetDIALOG unit.
• Next pass the connecting cable (6) from the operating
console through the opening in the upper front clad-
ding and connect to it the adapter cable from the ac-
cessory pack (4) for connecting between the vrnetDI-
ALOG unit and the heat pump.
The connector on the adapter cable is intended for the
operating console; the second cable is intended for con-
nection to the eBUS plug from the vrnetDIALOG unit.
h Note!
Any other eBUS cables already present
on the vrnetDIALOG unit are not re-
quired and can thus be removed.
• Now connect the aerial or telephone cable (3) to the
vrnetDIALOG unit (see also the vrnetDIALOG manual).
These cables must not be fed through the heat pump.
