Heating curves ■ The diagram shows the relationship between flow temperature and outside temperature. ■ The outside temperatures are shown horizontally and the flow temperatures are shown vertically. ■ The control unit is factory set to a room temperature of 20 °C in standard mode and 16 °C in reduced mode (setback mode).
  • Page 95 Commissioning, inspection, maintenance Further details regarding the individual steps (cont.) Example: This example uses the heating curve values from the screenshot. Assuming: the outside temperature is 7 °C, then the flow temperature will be regulated to 35 °C. If the outside temperature is 3.5 °C, then the flow temperature will be regulated to 38.5 °C.
  • Page 96 Commissioning, inspection, maintenance Further details regarding the individual steps (cont.) 19. Correct adjustment of heating curve and set temperature constants The heating curve is optimally adjusted if the standard room temperature results from the heating curve alone. Consequently, the temperature correction factor must be 0 when adjusting the heating curves.
  • Page 97 Commissioning, inspection, maintenance Further details regarding the individual steps (cont.) 21. Cooling circuits The cooling curve results from: outside temperature and set cooling temperature. This means only one offset and one slope can be adjusted. Cooling circuits are regulated and adjusted in the same way as heating circuits (Please note: observe the difference described above).
