replace timers with central heating programmer

[Greyspur]

Hi All,
I have an old, but reliable (thats done it now) Potterton Kingfisher gas boiler with a hot water tank and radiators on two floors zoned with Honeywell V4043 series valves.

The rads and hot water are individually wired via a fused spur into three Landis and Gyr electromechanical timers, two no longer work correctly (clocks broken)

I want to replace all three with a single programmer that will give me independent control of the three elements with the option to separately programme weekdays and weekends. I have the wiring diagram for the system. I'd like some advice as to which programmer would be suitable and reliable.

Have added a picture of the offending timers..................if that's any use

Thanks for any advice

Programmable room thermostats on each floor.
Sorted.
