My extension kit doesn't switch off.
I work with a Tado thermostat and an extension kit. I am trying to use the relay output of the extension kit and I connect between pins 1 and 4. Immediately after start up, I get signal at PIN 4 but it never switches of? Meanwhile the thermostat switches correctly, but the extension kit doesn't switch. I have put the settings of the thermostat like this:R01; HC01; HWx; EKv; R01.
Has somebody an idea how to solve this? I already asked support, but I never get an answer to my question. They just respond with links that lead to nowhere.
