5 System solution
Explanations for the positions are given after the images of the system solution.
5.1 System solution DHP-AQ Mini
DHP-AQ Mini includes the control module with supply and return line sensors. The heat pump produces only heat
or cooling. Two heating circuits can be connected, one using a shunt. The shunt is controlled by the heat pump
control system. The flow line temperature is controlled with reference to the outside temperature following a set
heat curve. The additional heater starts automatically on demand.
Buffer tank is installed for equalisation of the temperature for the heating system and to guarantee sufficient
energy when defrosting. The buffer tank volume must be 20 l/kW heat pump output (for systems without water
heaters). DHP-AQ Mini does not contain a water heater. Water heater is available as an accessory for DHP-AQ Midi
and is included in DHP-AQ Maxi.

5.2 System solution DHP-AQ Midi
DHP-AQ Midi includes the control module with supply and return pipe sensors, circulation pump, 3-way valve and
electric auxiliary heater. The heat pump produces heat, cooling and hot water. Production of heating and hot
water cannot occur at the same time because the exchange valve for heating and hot water is positioned after the
heat pump and the auxiliary heater. Hot water production is prioritised ahead of heat and cooling. Two heating
circuits can be connected, one using a shunt. The shunt is controlled by the heat pump control system. The flow
line temperature is controlled with reference to the outside temperature following a set heat curve. The additional
