Note!
Please see current price lists for infor-
mation on possible necessary accesso-
ries.
You can fit the following accessories to expand the heat
pump system. You can find more detailed information
on the installation of accessories in Chap. 6.9.
Mixer module VR 60
With the mixer module, you can expand the control sys-
tem of the heating installation by two mixer circuits.
You can connect a maximum of six mixer modules.
VR 90 remote control unit
A separate remote control device can be connected
for the first eight heating circuits (heat zone 1 -
heat zone 8).
VR 10 standard sensor
Additional sensors may be required, e.g. as flow, return,
collector or cylinder sensors, depending on the configu-
ration of the system.
vrDIALOG 810/2
vrDialog is a communications unit with software and
connecting cable which enables you to carry out diagno-
sis, monitoring and parameter setting on the heat pump
from a computer.
vrnetDIALOG 840/2, 860/2
The vrnetDIALOG communications unit enables you to
carry out remote diagnosis, monitoring and parameter
setting on the heat pump from a computer over a tele-
phone connection or via an integrated GSM modem.
Start-up current limiter VWZ 30/2 SV
The VWZ 30/2 SV is used to limit the short-term very
high current consumption which occurs when the com-
pressor starts up. This is recommended or stipulated by
some power companies.
VPS heating water buffer cylinder
The VPS buffer cylinder is used as an intermediate cyl-
inder for heating water and can be installed between
the heat pump and the heating circuit. It provides the
necessary to bridge over the power company blocking
periods.
VIH and VDH domestic hot water cylinder
The Vaillant VIH coiled tube tank and the Vaillant VDH
double wall tank are specially designed to be combined
with heat pumps and are used for heating and storing
hot water.
VPA combination cylinder
The Vaillant VPA combination cylinder can be fed from
various energy sources and is used for heating both
heating water and DHW.
VWZ compact collector
The VWZ ground collector system is used as a heat
source with a small space requirement and simple, fast
installation. It can only be combined with heat pump
types VWS 81/2 and 101/2.
External cooling VWZ NC 14/17
With the VWZ external cooling accessory, you can also
use the VWS 14 and VWS 17 heat pumps for cooling.
Other accessories
- Heat transfer fluid
- Filling pump
- Safety assembly and tundish
- Expansion vessel for the heating circuit
4.2 Requirements of the installation site
– Choose a dry room that is generally frost-proof.
– The floor must be level and sufficiently stable to be
able to bear the weight of the heat pump, together
with the DHW and possibly a buffer tank.
– It must be possible to install suitable pipe conduits
(for heat source, DHW and heating).
– When choosing the installation site, bear in mind that
when operating, the heat pump can transmit vibra-
tions to the floor or nearby walls.
– In accordance with DIN EN 378 T1, the minimum size
of the installation space for heat pumps, (V
min
), is cal-
culated as follows:
V
min
= G/c
G = coolant fill quantity in kg
c = practical limit in kg/m

(for R 407C c = 0.31 kg/m

)
This yields the following minimum installation space:
