You will still need a room stat to control the temperature in your house. You won't need the programmer, as the boiler will operate at the timings you set on it.
If you have a combined programmer and room stat (suitable for a combi, that I presume you have just had fitted), you could either;
1) Wire the combined stat and programmer to control the boiler, and not use the boiler's timer
or
2) Use the stat part of the programmer, and set the programmers timer to constant, and rely on the boilers clock for timings.
