"Clever" controller for central heating?

[Piglet]

Further to my thread about heating (link below), can anyone recommend a controller that would allow us to set different temperatures for different time sectors (ie to drop the temp at night but then set it warmer for getting up time?).

At the moment we have a Drayton controller which is very basic and a separate wall stat - is is straightforward to replace the controller with something more sophisticated?

Cheers
