I've wired up both my temperature controllers. The heating circuit works fine, but for some reason as soon as it switches to the cooling circuit my RCD trips.
I've wired them according to this diagram. Apologies for the quality. I'm not using my own computer and I couldn't figure out how to draw straight lines
You get the idea anyway.
The bit in the middle, marked LEN is a simple terminal block.
So, is there any reason my this would trip an RCD? Or should I (as I suspect) start looking at my fridge as the culprit?
