Old dial thermostat replacement

[bluechilli]

Hi
Wasnt sure if this is a CH or Electrics question so here goes..
I have a traditional Drayton dial thermostat on the wall and want to replace with a digital on with programmes ideally.
Here is a pic of whats there already, my question is, could someone PLEASE look on Screwfix and recommend a simple replacement unit. I need it to be as simple as possible, I have looked but Im not sure which wire would go where, Im sure I would have a couple of wires left that I would need to tape off.
All help appreciated
Martin

Buy a Honeywell CM907

You shouldn't need to alter the wiring much, though you might need to add a link between L and 1 (just going off the top of my head here)
