Caution
NIBE does not supply all components in this
outline diagram.
This installations alternative is suitable for more complex
installations with a focus on comfort.
SMO 40 (AA25) starts and stops the heat pump (EB101)
to meet the heat and hot water demand of the installa-
tion. At simultaneous heating and hot water demand
the reversing valve switches (AA25-QN10) periodically
between the climate system and the water heater/accu-
mulator tank (CP10). When the water heater/accumulator
tank is fully charged (CP10), the reversing valve switches
(AA25-QN10) to the climate system and pool. When the
pool needs heating the reversing valve (CL11-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.
Immersion heater (EB20) in the water heater/accumulat-
or tank (CP10) is used during the time to produce hot
water if the heat pump (EB101) is used for heating the
building at the same time.
The immersion heater (EB20) can also be used if a
higher temperature of hot water is required than the
heat pump can produce.

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 event of a hot water demand, the reversing
valve (EQ1-QN12) switches back and hot water is pro-
duced until the demand is fulfilled. In 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).
Active cooling (in 4-pipe system) is selected in menu
5.4 - soft in/outputs.
