Weishaupt Pump Control

Open dm82m opened this issue 1 year ago • 7 comments

Hey guys,

We live in a house build 2019. we have a weishaupt gas heating and a Grundfos alpha2 pump for heating circulation. Each year we have the problem that the pump is stuck. It got replaced last year but still the same issue this year. This problem occurs after summer when we turn on heating. Do you know if there is a feature that is letting the pump run for a minute a day in summer mode to prevent getting stuck. Or do you have other ideas? The installation company tells me that I have to run the pump manually each month. But to be honest, that can’t be the case, right?

thanks for your thoughts

@boysim how can this update be achieved? through wemportal? directly on the device? or only by a mechanic with additional hardware/software?

Weishaupt told me that this function is currently not existent. It is only available for the pump inside the heating itself but not for the external one for underfloor heating pump. They said that maybe there will be a firmware update end of 2024. So it seems that the only way is to externally power the pump in summer and ensure that it runs once each week.

@dm82m which software version do you currently have? update is done by putting all the update files on the sd card..
