*1
Operating point to DIN EN 255: W10 = groundwater i nlet temperature 10 °C/W35 = heating water outlet temperature 35 °C.
Operating point: W8 = groundwater inlet temperature 8 °C/W55 = heating water outlet temperature 55 °C.
Operating point: W8 = groundwater inlet temperature 8 °C/W65 = heating water outlet temperature 65 °C.
For further operating points, see the output diagrams.
