Connecting air/water heat pump
You can find a list of compatible air/water heat pumps in
section "Compatible air/water heat pumps".
Caution
Also, consult the Installer Manual for your air/water
heat pump.
Install as follows:
•
pressure relief valve
Some heat pump models have a factory-fitted safety
valve.
•
drain valve
For draining the heat pump during prolonged power fail-
ures. Only for heat pumps that do not have a gas separat-
or.
•
non-return valve
A non-return valve is only required in those installations
where the placement of the products in relation to each
other can cause self-circulation.
If the heat pump is already fitted with a non-return valve,
there is no need to install another.
•
shut-off valve
To facilitate any future servicing.
•
filterball or particle filter
Installed before connection "heating medium return" (XL2)
(the lower connection) on the vacuum pump.
In installations with a particle filter, the filter is combined
with an additional shut-off valve.

Climate system
A climate system is a system that regulates the indoor
temperature with the help of the control system in VVM 310
and, for example, radiators, underfloor heating, underfloor
cooling, fan coils, etc.
CONNECTING THE CLIMATE SYSTEM
Install as follows:
•
expansion vessel in connection XL30
•
pressure relief valve
Recommended opening pressure is 0.25 MPa (2.5 bar).
For information about max opening pressure, see technical
data. Install the safety valve as illustrated.
•
shut-off valves
Install the shut-off valves as close to VVM 310 as possible.
•
When connecting to a system with thermostats on all ra-
diators/underfloor heating coils, either a bypass valve
must be fitted or some of the thermostats must be re-
moved to ensure there is sufficient flow and heat emission.

Cold and hot water
The settings for hot water are made in menu 5.1.1.
CONNECTING COLD AND HOT WATER
Install as follows:
•
shut-off valve
•
non-return valve
•
pressure relief valve
The safety valve must have a maximum 1.0 MPa (10.0 bar)
opening pressure and be installed on the incoming domest-
ic water line as shown.
•
mixing valve
A mixer valve must also be installed, if the factory setting
for hot water is changed. National regulations must be
observed.

Installation alternative
VVM 310 can be installed in several different ways, some of
which are shown here.
