Intended relationship between the StandBy Mode and the "immidiate selection" ?

[JueBag]

What is the intended relationship between the StandBy Mode and the "immidiate selection" (in german "Schnelle Auswahl") function?
I noticed that the selection of the OneTimeCharge function while the system was in StandBy Mode was working. I was a bit surprised!
The system went back into StandBy after charging once.

Hi @JueBag ,

this is a ground function of the control unit.

Could you post your question in the "Gas" area of the forum: https://www.viessmann-community.com/t5/Gas/bd-p/customers-gas (in German). There you will receive feedback from our responsible colleagues from the gas wall hung boiler specialist group.

Best,

Michael
