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

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