Fig. 6 · 4-point characteristic
The 4-point characteristic allows you to define your own heating characteristic.
It is defined by 4 points for the Outdoor temperature , the Flow temperature, the Reduced flow
temperature and the Return flow temperature . The Max. flow temperature and Min. flow tempera-
ture 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. Optimization, Flash
adaptation) have been selected.
The 4-point characteristic function can only be activated when the Adaptation function is not
active (CO1, 2 -> F08 - 0).
