I'm changing my Honeywell T6360B thermostat for a Salus RT310 but am struggling to understand how the Honeywell is currently wired. The Honeywell website states
1 = Live
2 = Neutral
3 = Switched Live
but if you take a look at the attached photo the wiring doesn't match this. There is a brown sleeved black wire to 2 and nothing to 3.
