Functions of the heating circuit
5.1.2 Four-point characteristic
The four-point characteristic allows you to define your own heating characteristic. It is de-
fined by four points for the outdoor temperature, flow temperature, reduced flow temperature
and return flow temperature. The 'Max. flow temperature' and 'Min. flow temperature' pa-
rameters mark the upper and lower limits of the flow 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
,
flash adaptation
) have been selected.
− The four-point characteristic function can only be activated when the adaptation
function is not active (CO1, 2 > F08 - 0).
