I have the boiler above and my plumber has left me high and dry. He disconnected the thermostat so I cant control my heating temp and the blummin boiler is in the loft! I have wiring in for a programmer in my hall but plumber has done a bunk and left me with a cable hanging out of the wall. I need to know what sort of programmer to get to control my boiler and whether I need a plumber or an electrician to install it for me? Any help gratefully received. Thnks
