4.1 Accessories
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. 5.9.
Information on potentially required accessories.
Please see the current price list.
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.
VPS heating water buffer cylinder
The buffer cylinder VPS functions as buffer store for
heating water and can be mounted between the heat
pump and the heating circuit. It provides the required
energy to bridge the cut-off times of the supply unit op-
erator (VNB)

Requirements of the installation site
Install the geoTEHRM heat pump with integrated domes-
tic hot water cylinder in a suitable position in the build-
ing and at the same time, pay attention to the following:
– Choose a dry room that is generally frost-proof. A
frost protection thermostat must be installed if neces-
sary.
– 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.
– Floor unevenness should be able to be levelled from
the adjustable feet of geoTHERM heat pump
– An appropriate water supply pipe can be connected
directly from the mains water stop valve of the build-
ing with the geoTHERM heat pump.
– It must be possible to install suitable pipe conduits
(for heat source, DHW and heating).
– The discharge pipe from the tundish must be installed
at a minimum slope of 1:200 and end at a safe and vis-
ible point, see section 4.7, "Requirements for the do-
mestic hot water cylinder".
– There must be enough room for the assembly, check-
ing and pressure build-up of the expansion vessel.
– 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
3
(for R 407C c = 0.31 kg/m

)
This yields the following minimum installation space:
