[QUOTE="SPECIAL LOCATION, post: 552731, member: 250"] You have the wiring diagram for the new thermostat... But.. did you refer to the wiring diagram for the old thermostat..? i.e. which terminal is switched live out? "3" is typically used as switched live out on other similar Honeywell thermostats!! In BS7671 Brown Black and Grey are all live conductor identifications.. So assuming one is used as a neutral without any further cable identification is very bad practice. [/QUOTE]
