No it hasn't

I wired it

No not zoned It's a combination boiler used on kind of a S plan Valve for hot water only.. Cylinder stat set to 60 but boiler running continuously i.e cylinder stat not switching off ( water is red hot)

Hi John Just having an issue with it and thought I'd ask before I write war and peace about it..

Evening all Has anyone here wired the above boiler with a cylinder stat and a room stat via a 2 channel programmer?

Ah yes the m4 nut , bolt and washer so bloody fiddly and they suggest the washer goes on the inside of the bracket

Viessman vitodens 100-w

Not sure will check tomorrow , it's a new model Viessman but not sure on the exact type

Ok so the L on the pump is the switch live on a system boiler and one side of the stat on a combo boiler ??

It's two separate heating zones on a combo boiler

2 zone heating system with 2 separate wireless stats Sure its a combi as it only has a LNE connection and a 2 terminals for the stat wiring Sure system boilers have a sw live terminal
