Gradient Characteristic - Samson TROVIS 5579 Mounting And Operating Instructions

Functions of the heating circuit

5.1.1 Gradient characteristic

Basically, the following rule applies: a decrease in the outdoor temperature causes the flow
temperature to increase.
By varying the parameters Gradient and Level , you can adapt the characteristic to your indi-
vidual requirements:

The gradient needs to be increased if the room temperature
drops when it is cold outside.
