Hi All

I think this should be a pretty simple one... My honewell thermostat is wired to my oil boiler by 3 wires, live (brown), neutral (blue) and switched live (yellow+green, whoever fitted this used earth and did not mark it) as per photo.

The new Drayton thermostat wiring diagram is also shown (at top of photo) - it has live,marked as L, Neutral marked as N and common. Am i right in thinking that i wire the Drayton with Live (brown) to Common, neutral (blue) to N, and switched live(yellow+green) to L?

Many Thanks

Scratch that. Is it an oil combi boiler or zone valves?

Hi. its an oil boiler that only serves my radiators, it does not do anything else - sorry i dont know what zone valves means!

thanks for your quick help btw

my heating systme has only 1 thermostat, and 4 rads + a towel rail. The towel rail will always be supplied hot water (no matter what the thermostat says) unless i manually turn it off using the valves on the rail itself
