Hi, I have attempt to replace the Honeywell thermostat with the Digital Wifi one, the connection on Honeywell runs on 3 wires, I have added to the new digital one as follow, the red as Live In port L, blue as Neutral in port N and yellow in port 4 as switching live, but the central heating does not start to warm the heaters. What I have done wrong ? On diagram request 2 wires from the boiler but it come only one(yellow) apart of the Blue and Red, any ideea how to make it work ? Shall I run a Live wire bridge from 1 to 5 ?Appreciate !

If your boiler is 240 v switching a link from live to 4 then switch live from 5 to boiler ,
