17. 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).
■ The factor indicates the value by which the flow temperature is raised if the
system user increases the room temperature.
■ The following values can be altered to change the heating curve:
