As one can write directly #50 room temp, what additional benefit does the room sensor give?
When I first installed my ThermIQ-room and still wasn’t sure (and still have some doubts, but that is thing for another topic) to what terminals to connect room sensor I noticed that I could send mqtt topic to change room temp. That made me wonder what additional benefit having room sensor cables connected could give to me?
Register d50 (r32) is wanted temperature
ThermIQ-room is able to give the HP an ”actual room-temperature” thus giving the control-loop direct feedback.
Without room the ”actual room temperature” is not used but instead the return water temperature is used.
Ok, thanks. I also now get the benefit of the room sensor with you explanation as I noticed it simply changed the target, the same value that I was able to change directly from my Thermia Diplomat Duo Optimum.
I have to check why I don’t get this 20.5. It might be wrong connection as I simply used terminal 303/304 since I couldn’t find any details for my Thermia model (Thermia Diplomat Duo Optimum 8).
So I still can’t get the room sensor to work, maybe is is some other terminals? Any suggestions for finding diagram or confirmation them to be 303/304 for ”Diplomat Duo Optimum 8” I would be very grateful!
I only found obscure mention about the possibility to add room temperature sensor to this model in the manual, but no diagrams.
Only one diagram/picture behind the cover of the machine itself:
406: 303, 304
50: 305, 306
408: 307, 308
54: 311, 312
55: 325, 326
Physically 307/308 are the only other free slots in the same block.
