Room thermostat replacement

Hey there,

I’m living in a flat where there is a gastherme (6kW) running. And I got a “Room thermostat” with different settings for day and night:

Anyone out there who replaced the device from the 80s with some esp one together with HA?

Thanks in advance.


I would say that looks like a DC voltage not AC… but your first port of call is to work out if its AC or DC then you can figure out what solution will fit your case.
