Yes that's the wrong one
By Puma ELEC they mean Electronic ignition - no pilot.
I don't know what Abcot are flogging for pumas, could be something knocked up in a poppy planters shed in Afghanistan.

Is there the wee label with the board number on it, um...
21-18601
sorry I got that wron last time.
If so that's the potterton part. In fact the "Electronic" board has more bits on it than the pilot version, but IS lacking
1)the link LK1 which is vital to keep the fan on slow speed which the pilot version needs to keep it cool. Without it the boiler will overheat and cut out, while it's doing nothing.
2) the capacitor in the middle, C17, whose function I don't know.

If all the parts are on the board and there's nothing to adjust I can't see why an E board with the 2 parts added shouldn't be put in a P boiler.
Do you have a soldering iron? My email is in my profile and I have capacitors..

The potty P board is 21-18867


I still don't think the boiler can be behaving in quite the manner you indicate..
