I've moved into a new house and I'd like to upgrade to a smart thermostat, such as the Draton Wiser. Self installation seems do-able but I don't understand my current Honeywell thermostat CM907.
Most smart thermostat install guides show many wires coming into the backplate of the existing thermostat but mine has just a live and neutral (see image). My Honeywell is programmable and controls the heating so I don't think theres another control board in the house. I also can't find a wiring centre that most install guides show as being connected to the thermostat.
Am I getting confused by install guides for older, more complex systems, or do I need to locate some vital hardware? Any help would be appreciated
