Chaffoteaux inoa green 24 EU. Bus protocol doesn’t work with extension kit.


I’ve got a combi boiler Chaffoteaux inoa green 24. I’ve installed extension kit and wireless smart thermostat like in installation instruction by bus protocol.

But my boiler doesn’t work now on bus protocol with tado

Before i’ve got an on/off salus thermostat.

I think The problem Is that i need to make some changes in my boiler system to change on/off system to bus protocol but i dont know how.

Can someone help me ?
