5.1.2 4-point characteristic
The 4-point characteristic allows you to define your own heating characteristic.
It is defined by 4 points each for the
Outdoor temperature
, the
Flow temperature,
the
Reduced
flow temperature and the Return flow temperature . The Max. flow temperature and Min. flow
temperature parameters 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
4-point characteristic has been selected, provided no additional functions (e.g.
Optimiza-
tion
,
Flash adaptation
) have been selected.
