From the switch on before 3 weeks the pump can't go above 28 degC of the heating line. I watch the compressor cycle, it looks like some parameter is triping the compressor. There are no writen faults in the memory. I do full reset and nothing change. We have suspissions on the sensors, but after change...the same. Otherwise the pump works,but cannot go beyond this temperature.</P><P>What could be the reason?</P> Tue, 29 Oct 2024 05:46:24 GMT Simeon 2024-10-29T05:46:24Z https://community.viessmann.de/t5/Waermepumpe-Hybridsysteme/Vitocal-200s-problem/m-p/479588#M130062 <P>Hello to All,</P><P>I have a Vitocal 200s from an year.
