3 Installation instructions Mixer module VR 60 0020020171_02
These mixer circuits can be programmed via the
auroMATIC 620 or VRC 630 controllers,
or the operating section of the Vaillant geoTHERM
VW.. .../2 heat pumps or, if required, via a separate
VR 80 or VR 90 remote control unit.
Each mixer circuit can, as required, be switched be-
tween:
– Heating circuit (radiator circuit, floor circuit, etc.)
– Fixed value control
– Return flow boost
– Hot water circuit (storage tank charging circuit, in ad-
dition to integrated hot water circuit).
The "Return flow boost" and "Hot water circuit" options
are not available with the Vaillant geoTHERM VW.. .../2
heat pumps.
With the telephone remote contact connection (floating
contact) on the auroMATIC 620 or VRC 630, the con-
troller’s operating mode can be changed by telephone
by means of the teleSWITCH telephone remote switch.
2.1 Identification plate
The identification plate for the VR 60 mixer module is
located on the outside on the left hand side of the cas-
ing.
2.2 CE-mark/conformity
The CE label documents that the mixer module VR 60,
in connection with Vaillant boilers, fulfils the basic re-
quirements of the following directives:
– Directive relating to electrical equipment designed for
use within certain voltage limits (2006/95/EWG)
– Directive relating to electromagnetic compatibility
(2004/108/EWG)
2.3 Intended use
The mixer module VR 60 is a state-of-the-art appliance
which has been constructed in accordance with recog-
nised safety regulations. Nevertheless, there is still a
risk of death or serious injury to the user or others or of
damage to the device and other property in the event of
improper use or use for which it is not intended.
The VR 60 mixer module is a system component in the
auroMATIC 620 or VRC 630 modular bus control sys-
tems for controlling hot water central heating installa-
tions with integrated hot water generation. The VR 60
mixer module can also be used as a system component
with the Vaillant geoTHERM VW.. .../2 heat pumps for
controlling hot water central heating installations. Any
other use or extended use is considered to be improper.
The manufacturer or supplier is not liable for any result-
ing damage. The owner alone bears the risk. Intended
use includes the observance of the installation manual.
3 Safety instructions and regulations
The mixer module VR 60 must be installed by a qualified
engineer, who is responsible for adhering to the existing
standards and regulations.
We accept no liability for any damage caused by failure
to observe these instructions.
3.1 Safety instructions
e
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 switch on the VR 60, auroMATIC 620 or
VRC 630 or the Vaillant geoTHERM VW.. .../2
heat pumps is not in itself sufficient to ensure
that all the terminals on the system are volt-
age free.
3.2 Regulations
All wiring must be in accordance with Building Regula-
tions Part P and BS 7671 (IEE Wiring Regulations), and
must be carried out by a suitably qualified person.
Standard cable must be used for wiring.
Minimum cross-section of the cable:
– 230 V connecting cable
(pump or mixer connection cable) 1.5 mm 2
solid conductor
– Low-voltage leads
(sensor or Bus leads) 0.75 mm 2
Do not exceed following maximum wire lengths:
– Sensor connection
50 m
– Bus lead 300 m
If sensor and eBus leads run parallel to 230 V leads over
a distance greater than 10 m, they must be laid sepa-
rately at a spacing of at least 25 mm.
230 V connection leads must be implemented with
1.5 mm
2 solid cable and fastened in the casing using the
cable clamps supplied.
Do not use free terminals of the appliances as support
terminals for other wiring.
The unit must be installed in a dry room.
