Some more calculations #109

Closed gerw closed 1 year ago

gerw commented 1 year ago

This was already mentioned in #101:

I took the opportunity to identify some more calculations. For some reason, the energy from the heating rod seems to be a parameter.

Calculations 232,233, 236-243 can be seen in the web interface if you are logged in as after-sales service. I also have taken the liberty to rename calculation 241, since "Circulation_Pump" sounds (at least for me) like Zirkulationspump/ZIP which is something different.

For me, calculations 234 and 235 are always "0".

By the way: My heating rod uses 6kW but is configured to 9kW. This seems to be parameter 1025 with--yet another--a scaling factor of 100W. Can anybody confirm this? However, I do not find a menu in which I could set my heating rod to 6kW.

Have you tried (or does it even make sense) to write parameter 1025 in order to represent the actual power that is used / attached to the heating element? If this parameter is used internally to integrate the energy consumed, it will be wrong by quite a bit (33% or 66%), depending on the actual physical connection.

In my case I have only 3 kW attached, so I'm wondering whether I can easily change this value? As you've already mentioned there seems to be no such setting in the menues, etc.?

Maybe we should contact the support about this :-)? Last year they have been quite friendly towards me, but haven't been in touch for quite a while.

No, I did not write to parameter 1025. Since I am not sure what this parameter represents, I do not feel like writing to it...

And yes, the energy of the heating rod is integrated incorrectly (by using 9kW)

Okay, thank you for the heads up. Let's see if I feel brave enough to write this value at some point. Doesn't sound too dangouers, but at the end there is no guarantee of course.

Will you prepare another pull request for this parameter? As said in the other discussion, I can confirm that his is 90 for me, although physically I only have 3 kW connected.
