What adapter should I get?
I'm trying to install a forth tado radiator thermostat, but non of the adapters seem to work. I send photos of the valve to tado's support together with my assumption that it might be M28 x 1.5 valve. They didn't even look at the photos to confirm if the valve is actually this size and just asked how many of the adapters do I need, since they were missing in my set.
Can someone help me identify what valve is this?
