Gah! It’s working... except... it seems to be doing the opposite of required ... when the thermostat tells the receiver to be on, the boiler goes off and when the thermostat tells the receiver to be off, the boiler comes on??
Ok, thanks. Kids just going to bed, once asleep I’ll turn the power off. I’ve just found this pic elsewhere, have I got the brown and blue wires the wrong way round?
Thanks, we assumed the blue wire going into common was a live wire from the boiler, how can we check?
the boss therm had a loop wire from L to LX, not sure if that means anything??
Help! I am swapping out a boss therm thermostat for a hive on my Worcester Greenstar Heatslave 18/25. I have wired it all up, everything is talking to each other, the boiler is set to “on” for heating and water, the boiler is working for hot water but it just won’t come on for heating! Any...
