Hi Everyone,
I have few electrical jobs to do for my client and one of them to fit Nest Thermostat 3d generation. I decided to give a go as I haven't done much wiring for heating system in the past. But willing to learn. The boiler is Glow worm Ultracom 15hxi. I thought i would need to simply reconnect wiring from programmer to heat link and wired heat link as follows: mains to LN, link from L to terminal 2 and 5(common) , Blue wire to terminal 3, yellow wire to 6, red wire to 6.
The nest thermostat & heat link are paired but it doesn't turn the boiler on as I increase temperature on new thermostat.
I've made pictures of programmer's wiring and wiring coming out from boiler. Maybe I need use boiler wiring?
The client says that she using boiler controlls to heat up the house, not programmer or old thermostat in the living room if that helps.
Any advice is welcome.
Regards
Igor
