NIBE VVM 500 3
Design
NIBE VVM 500 is equipped with an intelligent and easy to use
controller. The controller optimises the two circulation pumps.
Both the flow to the outdoor heat pump and the flow to build-
ing are adapted to actual demands on heating or hot water. The
required input is defined by the installer during the start up pro-
cedure.
The controller is intuitive for both installers and end users. If a
problem occurs there are several ways to log and analyze select-
ed parameters. Software updates are downloaded via the USB
connection.
The hydraulic concept offers true flexibility and a robust instal-
lation. The lower part of the cylinder is used as a heating buffer
volume, meaning no extra buffer volume independent of the
building’s heating system is needed.

"Dimensioned outdoor temperature
Energy is provided to the NIBE VVM 500 by the outdoor heat
pump to the top of the tank or to the bottom depending on de-
mand. Solar panels can be connected to the built in coil and so-
lar energy can be used for hot water, heating a pool or indoor
heating. In the latter case heating water above the stratification
plate is transferred into the heating system. An existing boiler
can be connected to the upper water volume. Another way is
to feed energy using the immersion heater. It can be used for
heating and hot water backup. The controller decides when and
how much of the available energy sources should be fed into
the NIBE VVM 500. It also prioritizes demands for heating, hot
water and swimming pool.
