die Warnungen haben ja die gleiche Fehlernummer. Zumindest hatte ich vor langer Zeit erst eine Warnung dann einen Fehler mit der gleichen Nummer und Text. Sehe das im Störspeicher der WMP, hatte damals aber noch nicht via Modbus verbunden.
I am wondering if this behaviour of my Weishaupt heatpump WWP with WKS 300/100 is normal.
I noticed that everytime my heatpump produces hot water, the floor heating feed (Vorlauf) and return (Rücklauf) flow also increases to the hot water temperature. Does your system behave similar?
I don’t think you have the floor heating feed here. You have to install an additional sensor for that (mostly used for cooling).
In my opinion you monitor the heating feed of the heatpump. The valve directs this to your warm water and not the floor heating.
What entitiy do you use?
33104, “Vorlauftemperatur”
31105, “HZ_Vorlauftemperatur”
EDIT:
Denpendant on what version of the integration you use, HZ_Vorlauftemperatur may be hidden.
@MadOne: Thank you very much for your suggestion.
That makes sense, the Vorlauf could be the one from the heatpump and not the heating specific one. But even the heating specific Rücklauf shows the high value. Also the analog readers show the values.
I have waited for the warm water heating slot and checked the heatpump itself … if I understand this correctly, it’s showing the high temperature value even via the display:
Also the analog temperature readers show it (Heating Rücklauf/Return, Heating Vorlauf/Feed, Warmwater):
Do you have radiators or floor heating?
Gauges from left to right:
Return heating
Heating feed
Warm water feed.
So you would have a delta T of 40°C in your heating system.
Further your heating return is at 20°C. This would imply your room Temperature is FAR below that.
I suggest to check the gauges.
Where is your switch valve? It might also be possible that the temperature “sneaks” through the pipes to the gauge.
I have floor heating.
You are right, taking the manual gauges into account it rather looks like some warm water crawls into the floor heating feeding.
I will try to take some more pictures to see if its always like this.
Sorry, I am pretty late with this 
33104 doesn´t wotk for me, but now I found your post with 33111 and that works for my WGB 8 as well with a 0.1 degree resolution, great ! Thanks for sharing! Have you also found an address for return flow temperature?

It can be thermal energy that is conducted by the metal pipes.
To check: Turn of the valves for floor heating and push warm water.
A infrared thermometer might be a good tool to.
Dont forget to open the valves after this test.
