Danger of death by electric shock!
Before carrying out work on the controller,
switch off the power supply and secure it
against being switched on again.
Operating the mains switches on the VR 60
mixer module and on the auroMATIC 620 or
VRC 630 controllers or the Vaillant
geoTHERM VW.. .../2 heat pumps is not in itself
sufficient to ensure that all the terminals on
the system are voltage free.
If the casing of the VR 60 mixer module is closed, open
it as described in Chapter 4.3.
5.1 Connecting the mixer module to the building
• Wire up the VR 60 mixer module as shown in Fig. 5.1.
• Use the supplied eBus connection cable to incorporate
the mixer module VR 60 in the communication sys-
tem. The eBUS can be branched at any part of the
system.
In the entire system the mains infeed should be provid-
ed by the building works on one component.

Note!
Please make sure that the VR 60 mixer module
has a mains switch with which you can switch
off the internal electronics as well as all con-
nected actuators (pumps, mixers) for the pur-
poses of tests and maintenance.
