Gradient Characteristic - Samson TROVIS 5573 Mounting And Operating Instructions

5.1.1 Gradient characteristic

Basically, the following rule applies: a decrease in the outdoor temperature causes the flow tem-
perature to increase in order to keep the room temperature constant.
By varying the parameters Gradient and Level , you can adapt the characteristic to your individ-
ual requirements:

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

The gradient needs to be decreased if the room temperature
rises when it is cold outside.

The level needs to be increased and the gradient decreased if
the room temperature drops when it is mild outside.
