Hi all, My supplier sent me DO8EZ magnetic door sensors instead of DO8EZS that I had ordered as expansion for my Galaxy G2-44+ with RF C079-2 portal. It appears that DO8EZS have gone out of stock. I have found documentation that DO8EZ is not compatible with G2-44+ and indeed they were not...

Hi All! I've bought a NEST learning thermostat 3rd Gen with a wireless controller. When I opened up my Honeywell thermostat on the boiler, it was wired with Live, Neutral, Earth, and the 1 and 4 wires: I followed the advice of a thread online which said to wire everything the same on the...
