Boost mode not error-free

[SeibeGitHub]

Buderus GB182i.2-20

BC400 V3.07.43

Boost works correctly from 1-4 hours, from 5 hours it is only active for 45 minutes. It seems as if calculations are being carried out in minutes with an 8-bit data type (decimal max 255) in the BC400. E.g. 4 hours = 240 minutes 5 hours = 300 minutes overflow! 300-255=45 can anyone confirm this? The error lies in the BC400 control

Perhaps @Bingo2023 can verify?

Set via Home Assistant and checked with Buderus App.

Seems like 8h is max, 1-8h are working in my system.

Hello,

does boost really run for 8 hours? Or just 225 minutes for 8 hours. The quickest way to test the error is to turn on the boost for 5 hours and then it switches off after just 45 minutes. I have already been in contact with Buderus, they have confirmed the error and it should be fixed with new BC400 firmware in mid-2024.

@SeibeGitHub
they really talk to you?

I never got anyone from this company talking to me... which way did you contact them?

I made a complaint through the installer and after Buderus customer service was at the house I had a contact person.
