Question

How to set up the Soil heating control?

 Answer 

The setpoints for the soil heating can be found as follows:

 




The measured and target soil temperature.

 

The pipe temperature is calculated based on the deviation between measured and target soil temperature.

Example:

The calculated P-value during decreasing bottom temperature.

Soil temperature °C
Calculated P-value °C
20

18
28
16
36

52
10

The pump is switched on when the calculated pipe is higher than the setpoint “pipe temperature: pump ON”.
