Four-Point Characteristic - Samson TROVIS 5500 Operating Instructions Manual

Functions of the heating circuit

5.1.2 Four-point characteristic

The four-point characteristic allows you to define your own heating characteristic.
The four-point characteristic is defined by four points for Outdoor temperature and for Flow
temperature. The set-back difference is entered for points 1 and 2 as well as points 3 and 4. This
results in the dashed line in Fig. 2.
The Max. flow temperature and Min. flow temperature parameters mark the upper and lower li-
mits of the flow temperature.
