11 NIBE BA-SVM 10-200
The BA-SVM 10-200 indoor unit is equipped with a
storage tank with a hot water coil, expansion ves-
sel, safety group, electric additional heat, reversing
valves, plate heat exchanger, energy meter, electron-
ic circulation pump and controller. Combined together
with the NIBE SPLIT (AMS 10) outdoor air heat pump
unit, it forms a complete climate system.
The AMS 10 outdoor unit supplies thermal energy for
heating domestic water, powering the climate sys-
tem, heating swimming pools and cooling operation,
using free energy contained in the air outside, work-
ing efficiently in the low temperature range, as low
as -20°C.
The connection of the outdoor unit and the indoor unit
BA-SVM 10-200, with a system of pipes filled with re-
frigerant, protects the connection against freezing in
the event of interruptions in the electric power supply
to appliances. The system’s operations are controlled
using an advanced controller.
The control mechanism of BA-SVM 10-200 allows for
two cooling operation systems to be used:
• 2-pipe cooling system,
• 4-pipe cooling system.
System diagram
NOTE
BA-SVM is equipped with all temperature sensors as
standard. In some system layouts, the sensors must be
transferred to other parts of the system. For location of
the sensors, see the relevant point on docking the sys-
tem.
NOTE
In the event that the water volume of the central heating
system is increased using a buffer vessel, you will need
to check the system volume and possibly increase the
volume of the existing expansion vessel.
Section 4 | Pipe connections
If the standard initial pressure in the expansion vessel
is too low, this can be increased by filling it via the
installed valve. The expansion vessel’s standard initial
pressure must be entered in the checklist on page 5.
Any change in the initial pressure affects the ability of
the expansion vessel to handle the expansion of the
heating medium.
CAUTION
In order to obtain the minimum undisturbed flow in
the climate system, use the appropriate hydraulic solu-
tions (e.g. relief valve, low loss header, parallel buff-
er and/or open heating loops). Remember to always
maintain the minimum required flow in the system -
see the subsection “Minimum system flow”.

Minimum climate system volumes
NOTE
It is recommended to have an expansion vessel in the
hot water system. However, it is required to install a
safety valve with the required opening pressure.
The heat pump installation requires an appropriate
volume of heating medium (approx. 10l/kW heat
pump power) and a minimum, undisturbed flow.
In case of an insufficient amount of heating medium
in the installation, an additional buffer vessel must be
used, which will ensure adequate system volume,
see subsection “Minimum climate system volumes”.
An insufficient flow in the central heating system will
cause malfunction of the heat pump installation and
could lead to serious damage of the product.
