Caution
NIBE does not supply all components in this
outline diagram.
Caution
Different types of demand (heating, hot water
etc.) mean different supply and return temper-
atures as well as different flows to the heat
pump.
When connecting pipes in installations with
several compressors and different heating de-
mands, ensure that these are separated so that
different return temperatures are not mixed.
Otherwise this can affect the heating installa-
tion's efficiency.
This installations alternative is suitable for more complex
installations with a focus on comfort.
SMO 40 (AA25) starts and stops the heat pumps
(EB101) and (EB102) to meet the heating and hot water
demands of the installation. The heat pump (EB103) is
used for heating and pool heating and heat pump
(EB104) is used for cooling, heating and pool heating.

At simultaneous heating and hot water demand the re-
versing valve switches (AA25-QN10) periodically
between the climate system and the water heater/accu-
mulator tank (CP10). When the hot water heater/accu-
mulator tank is fully charged (CP10), the reversing valve
switches (AA25-QN10) to the climate systems. When
the pool needs heating the reversing valve (CL11-QN19)
or (CL12-QN19) switches from the climate system to
the pool system.
Additional heat (EB1) is connected automatically when
the energy demand exceeds the heat pump capacity.
Additional water heating is obtained from the additional
water heater (EB10).
During cooling operation (requires compatible heat
pump), the reversing valve (EQ1-QN12) switches to the
cooling system (EQ1). If several demands occur while
there is a cooling demand, the installation reacts differ-
ently. In the event of a heating demand, the reversing
valve (EQ1-QN12) instead switches periodically between
the demands. When the cooling demand is met, the
reversing valve switches back to basic mode (heat/hot
water). In the event of a pool heating demand, the re-
versing valve (EQ1-QN12) switches back at the same
