i have just bought one of these and i want to fit it to my eurocombi,i know it needs a live and neutral so i gather i need 2 core 7mm wire as per instructions,but what wire do i need to go to the relay A and B terminals i know its 7mm do i also need a 10amp inline fuse? and do i connect the relay to the boiler as if i was connecting a wired thermostat?i am not too bad at electrics,but would i be better off paying an electrician to fit it,any constructive help appreciated.
thanks.
thanks.
