Puma 80 central heating?

Hi again,

OK - I managed to fix mine..... it was due to a dry joint on the modulator board that had then burnt out. I fixed the joint again (and fixed quite a few others that looked about to burn out). Check the board for burnt out joints.

I dare say if yu get an engineer out - they'll just replace the whole board. Of course, yours might not be just a dry joint, but something else.

Hope this helps.

Neil - did you need to replace the main modulator board or the pcb which houses the two temperature sensors? Mines done exactly the same, i'm just trying to determine which board to replace.
