Replace digistat scr with a fixed c\h programmer?

Can you please recommend a non wireless fixed on the wall central heating programmer and thermostat that can replace my digistat scr and rf601
I have a greenstar 28i junior and the built in timer mt10 no longer works under timer mode so I leave it on all the time
and control via thermostat. The digistat is now also proving unreliable.

Is there a central heating programmer that incorporates a 7 day timer and a thermostat and uses the same wiring as the digistat so I can just replace it and fix onto the wall next to the boiler.
Many thanks for any advice.
