I want to replace my thermostat with raspberry pi board. I have already connected solid state relay to rasberry pi and it works just fine. The only part left to do is to connect solid state relay to the thermostat. I have an idea how to do that but before actually connecting anything I want to ask your advice if I am doing it right. My solid state relay looks like this
And the diagram on the thermostat looks like this
I have 4 cables
Blue - N Red - L Call - yellow and ground yellow/red
So I think I should connect Red(L - Red) to SSR contact 1(ac in) and CALL (yellow) to the SSR contact 2 (Load). Is that the right way to do ?
P.S. Its in UK so voltage is 220V therefore I want to be extremely careful
