Yep, that is similar to the sensors I found, cant find the third so far. It is 51° here this morning, the heat pumps work great!!
Near 90° next week, will give an update then.
Taping hot/cold bags to wall, there are some really ingenious people here!!
Looked up as typing this and saw the 3rd sensor under cabinet...….
Thanks for the manuals, most of what I found were older posts in this forum!
