Replace programmer?

Have Glowworm Micron 80FF boiler GC41-047-51. Controlled with Randall 4033 mechanical timer. I need to know how to rewire the above boiler to a new Greenbrook T62-C programmer. Can anyone help.

The boiler uses a permanent live neutral and earth from the spur, then you need switch live onto sl and pump live on to p/l. These 5 connections are a must on the boiler, the pump live will more than likely be already on so just disregard it basically the boiler controls the pump and the live feed for the pump comes direct from the boiler not anywhere else. Hope this helps.
