Function
The heat pump prioritises hot water charging. The circulation pump GP1 operates at the fixed set speed. When theheater is fully charged QN10 switches to the heating system. The heat pump works to a calculated set point value onthe flow line. If the compressor cannot meet the whole heating requirement, additional heat is shunted in as necessary.

1)Max. permitted impedance in the mains connected point in accord-ance with EN 61000-3-11. Start currents can cause short voltagedips that could affect other equipment in unfavourable conditions.If the impedance in the mains connection point is higher than thatstated it is possible that interference will occur. If the impedance inthe mains connection point is higher than that stated check withthe power supplier before purchasing the equipment.2)With feet dismantled the height is approx. 1930 mm.
Working range heat pump, compressor oper-ationThe compressor provides a flow temperature up to 65°C, the remainder (up to 70 °C) is obtained using theadditional heat.
