Heating characteristics Steps to take Example
The living space is too cold during
spring/autumn , but warm enough dur-
ing winter.
Adjust the heating curve slope to the next
lower value and the level to a higher value.
Slope 1.3
Level 3 K
The living space is too hot during
spring/autumn , but warm enough dur-
ing winter.
Set the heating curve slope to the next high-
er value and the level to a lower value.
Slope 1.5
Level -3 K
Note
Setting the slope or level too high or too low will not result in damage to your heating system.
For technically-minded system users
■
Heating curves illustrate the relationship between the outside temperature and the flow temperature. To put it
simply: The lower the outside temperature, the higher the flow temperature.
The heating curves shown apply with the following settings:
■
Heating curve level = 0
A different setting for the level will shift the curves in parallel in a vertical direction.
■
Standard room temperature = approx. 20 °C
In the delivered condition, the control unit has been programmed as follows:
■
Slope = 1.4
■
Level = 0
