NOTE
Not all components are shown in this
outline diagram.
Controller (AA25) starts and stops the heat pump (EB101) to
meet the heating and hot water demand.
At simultaneous heating and hot water demand, the reversing
valve (AA25-QN10) switches periodically between the climate
system and the water heater/accumulator tank (CP10). When
the hot water heater/accumulator tank is fully charged, the
reversing valve switches to the climate system.
Additional heat (EB1) is turned on automatically when the
heating demand exceeds the heat pump capacity. This is used
for both heating and charging hot water.
The additional heat can also be used for water heater when a
higher temperature is required than the heat pump can produce.
During cooling operation, the reversing valve (EQ1-QN12)
switches to the cooling system (EQ1). If several simultaneous
demands occur while there is a cooling demand, the system
reacts differently. In the event of a hot water demand, the
reversing valve switches back and hot water is produced until
WKHGHPDQGLVIXO¿OOHG,QWKHHYHQWRIDKHDWLQJGHPDQGWKH
reversing valve switches periodically between cooling and
heating. If the cooling demand is met, the reversing valve
switches back to basic mode (heating/hot water).
