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.
