Samson TROVIS 5579 - Gradient Characteristic

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.
The gradient needs to be decreased if the room tempera-
ture 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.
The level needs to be decreased and the gradient increased
if the room temperature rises when it is mild outside.
