What am I looking at here? 1997 Trane unit.
Where did the wires go?
Rain gauge maybe …
flux capacitor ?
Was there irrigation valve box nearby?
Unknown device attached to the HVAC condenser. Recommend the seller be questioned as to its purpose.
The black wire disappeared into the soil. The yellow went nowhere.
Looks like a rain sensor, the 3rd wire is if you want to wire it normally open or closed, usually used to shut the irrigation off during rain. I have never seen that model, however.
Did the house have an inground sprinkler system?
While it’s mounted like an irrigation rain sensor, it looks nothing like any I have ever seen.
Large spring loaded device with a removable sleeve filter, installed in a bottomless cup?
It is my best guess from afar, I have never seen one like that before either, it could be something else, thus my question about valve box nearby.
I believe so. Most in the development do. I don’t inspect irrigation systems so I didn’t pay much attention.
Glowplug. Not recommend for Ohio.
