Old School Enerzone Statnet thermostats for in floor radiant

Working on a radiant floor setup in our company owner's house (we do commercial refrigeration)
has 5 zones and 5 thermostats, old Enerzone Statnet communicating thermostats (company long out of business). No central controller and no serial connection to anything. So just using the stats like a dumb thermostat. Zones are a kitchen and 4 bathrooms. Each room has hydronic air as well.
Check out the wiring on this stat though. That's shielded in-wall speaker cable running to each stat. Yes, the 24V terminals at the bottom are live. Not sure where they terminate, and they aren't daisy chained because there's each thermostat is end terminated.
W1 and R go to a Taco zone valve controller which is wired to each 24v zone valve. Nowhere in the zone valve box or surrounding area are any yellow shielded wires.
Wondering if anyone has any ideas about the "1" and "2" terminals. This house does have a whole home Lutron blah blah blah (built in ~1990), but as far as I can tell no central touch screen / controller / etc anywhere.
No chance that's an in floor temp sensor right? I didn't think to ohm it out but the cable appeared to run up the wall, not down to the floor.
The other terminals match up to a RobertShaw thermostat, but RS terminals are for a remote sensor bus (serial bus for remote temp sensors) and CLK is for remote input setback (but I would have thought was clock input for the serial bus).
Alright, so tell me what you're thinking when you see this? My recommendation to them was just replace with 5 ecobee's and throw the temp sensor near the tile floor and run it fully off the remote sensor to control floor temps. Make sense? or no?

It appears that no one on this forum is familliar with that product or company. https://forum.heatinghelp.com/discussion/166158/what-interfaces-with-an-airzone-damper-control-system back in 2018 this ont got the same response as this discussion.

After you make that expensive repair and you still have the same problem, What will you check next?

My recommendation is to scrap all the "unknown" devices and put in something "Honeywell"ish. They haver been around for 100 years and up until the name change to Resido, seem like they will be around forever.
