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 parameters Max. flow temperature and
Min. flow temperature mark the upper and lower limits of the flow temperature.
