Dear forum,
My boiler has just had a new pcb (primary and secondary controllers) installed by the local reputable and popular engineer. It has also been serviced and runs nicely. BUT it only uses a maximum of 31kW of gas versus 41kW last year. The gas pressure is okay, the jumpers in the correct places. It comes up with 2.2 code on start up so the controller really thinks its an HE 36. This is the maximum it will run at (boiler thermostat as max and boiler fully cold). The only other feature is that when they first put the new pcb and face panel in they did not read the instructions and first put a new (orange) pcb in with the old face (not compatible I believe) and then put the new (orange) pcb in with a new face plate but did not set the jumpers to the right place (just copied the old unit). At that point it ran at only 18kW !
Have asked ideal directly and they have never heard of such an issue.
Any thoughts would be greatly appreciated as I am puzzled.
