6 Shunt controlled additional heat General This connection enables an external additional heater, e.g. an oil boiler, gas boiler or district heating exchanger to aid with heating. The heat pump controls a shunt valve and a circulation pump via AXC 0. If the heat pump cannot maintain the right flow temperature the additional heating starts. When the boiler temperature has been increased to about C, the heat pump sends a signal to the shunt (QN) to open from the addition. The shunt (QN) adjusts so the true flow temperature corresponds with the control system s theoretical calculated set point value. When the heating requirement drops sufficiently so the additional heat is no longer required the shunt (QN) closes completely. Factory set minimum connection time for the boiler is hours (adjustable in menu..). Pipe connections The external circulation pump (GP0) is positioned according to the outline diagram. Shunt valve The shunt valve (QN) is located on the flow line to the climate system after the heat pump according to the outline diagram. Connect the flow line from the heat pump to the external heat source A AB via the T-pipe to port B on the shunt valve (closes at reduced signal). B Connect the flow line to the climate system from the shunt valve to the common port AB (always open) Connect the flow line from the external additional heat to the shunt valve to port A (opens at increased signal). Temperature sensor Install the boiler sensor (BT) in a suitable location in the external addition. External flow temperature sensor (BT, connected in F/F) must be installed on the flow line to the radiators, after the shunt valve (QN). K Install the temperature sensors with cable ties with the heat conducting paste and aluminium tape. Then insulate with supplied insulation tape. NOTE Sensor and communication cables must not be placed near power cables. Chapter Shunt controlled additional heat AXC 0

22 Groundwater pump General With AXC 0 a ground water pump can be connected to the heat pump if the software controlled output (AUX output) is used for something else. This connection enables the use of ground water as heat source. The ground water is pumped up to an intermediate heat exchanger. An intermediate heat exchanger is used to protect the heat pump's exchanger from dirt and freezing. The water is released into a buried filtration unit or a drilled well. The ground water pump runs at the same time as the brine pump.
