Hi guys

I have a worcester boiler with connections: L, N, Ns, Ls, Lr

A cylinder stat with connections COMMON, DEMAND CONTACT, SATISFIED CONTACT

A central heating valve L, N, E, C, NO

A hot water valve L, N, E, C, NO

A underfloor heating valve L, N, E, C, NO

A programmer L, N, HW OFF, CH OFF, HW ON, CH ON

Two Wireless thermostats one for Underfloor heating and one for Central heating L, N, COMMON, HEATING SATISFIED OR CALL FOR COOLING, CALL FOR HEAT

and finally one wiring centre. 1-12

I know there is a lot of information there but im confident that someone who wires these day in day out will be able to help me.

Thanks very much, adam.

What you have there is an 'S' plan heating system with an additional zone for the UF.........'S' plan plus.

If you look in our 'central heating' forum :smart: you will find diagrams of all the heating systems there to show you.
