I've got a Worcester 35CDi (condensing combination boiler). I've recently bought a programable timer - a Honeywell CM67.
With the CM67, there is a R6660D box which connects directly to the boiler.
I have these instructions from the boiler:
- Remove Link
- Connect room thermostat LIVE supply to terminal (Ls)
- Connect room thermostat Live return to terminal (Lr)
- Connect room thermostat NEUTRAL to terminal (Ns)
But on the R6660D box, there is no indication which is the LIVE supply, LIVE return or NEUTRAL.
The instruction with the CM67 comes with a wiring diagram. On the wiring diagram there are only 2 links comming from the boiler to the R6660D box.
Any help would be gratefully received.
Thanks, Bob
