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. 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).
During cooling, the shunt groups are controlled in the same manner in system solutions both with and without a buffer tank.
An addition to the system circuit is also implemented.
The by-pass valve for active cooling and buffer tank is controlled as follows:
When active cooling is activated, the valve does not release if heating of the buffer tank is required. Instead, the heat is sent to the
cooling circuit.
DHP-iQ Mini does not contain a water heater. Water heater is included in DHP-iQ Maxi.
