That sounds small enough for radiator circutes with outlet temps > 50°C. But for low temperature floor heating systems with outlet temps between 25-35°C it makes a noticeable difference if the outlet temp deviates 1K at 25°C target temp. It becomes worse in cooling mode, where we should not fell below 18°C (dewpoint issue). Is there a way to adjust this deadzone anywhere? It seems to me hardcoded... many thanks in advance

Although this information is stored in the internal non-volatile Memory, the Parameter cannot be accessed over communication interface. So, I am very sorry, but the neutral zone cannot be adjusted. Best Regards [rvb]
