hi all I purchased a netatmo smart thermostat as replacement to my existing dumb wireless stat. I thought it would be a straight swap but not so sure now. The old stat has live, neutral and switched live. The netatmo has 4 wires in the ‘boiler adapter’ and I’m not sure how to connect it. In...

hi all, quick update. Nest is now purchased and installed - thanks for all your advice. It took quite a while to get it all wired up and ensure everything connected where it was supposed to. Whilst I could have rewired everything to ensure consistent use of colours etc (per freddo) this would...
