Functions of the heating circuit
6.1.2 Four-point characteristic
The four-point characteristic allows you to dene your own heating characteristic. It is de-
ned by four points for the outdoor temperature, ow temperature, reduced ow temperature
and return ow temperature. The 'Max. ow temperature' and 'Min. ow temperature' pa-
rameters mark the upper and lower limits of the ow temperature.

Note:
− The 'Day set point' and 'Night set point' parameters are no longer available when
the four-point characteristic has been selected, provided no additional functions
(e.g. optimization, ash adaptation) have been selected.
− The four-point characteristic function can only be activated when the adaptation
function is not active (CO1, 2 > F08 - 0).
