Cannot find config for my room therostat

beachman

Hi I have bought the tado wired smart thermostat V3. The idea was to replace the room thermostat for my Ariterm Biomatic +20 boiler.

The factory thermostat can set the desired temperature, measure the room temperature, display outdoor temperature and display alarms from the boiler.

I'ts the same thermostat that is used for the brands Ariterm, Thermia, Danfoss here in Sweden. The thermostat is developed by Kimsafe. The thermostat only has two wires. I guess its an digital interface because it can both read an set data to the boiler.

But I don't know what bus interface I should use, I cant find the brand in the manual!?

Se pictures. The thermostat is connected to the boiler on number 14-15 se yellow mark

Hello, do you find an interface bus for your interface?
