Long time lurker, first-time poster, moved into a home recently that was allegedly pumped prior to moving in. I’ve never had a septic, but want to confirm that’s what it is… oozing green liquid and when you move the sarcophagus it’s a gross black goo.

Guessing it’s not an artisan spring…

So I have a 2 zone system, set up a nest for the main level thermostat without issue, then found my upstairs 2nd zone Honeywell thermostat to have 1,2,3 connections. Opened up my main furnace panel and I do not see an EIM to bypass. It appears to be wired directly to the panel but I don’t believe it should work without an EIM.
