- Page 16 System solution DHP-iQ Mini DHP-iQ Mini includes the control module with supply and return line sensors. The heat pump produces only heat or cooling. Two heat- ing 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.
- Page 17 DHP-iQ System solution DHP-iQ Maxi DHP-iQ Maxi includes the control module with supply and return pipe sensors, circulation pump, 3-way valve, electric auxiliary heater and water 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.
