Hi,
Had some good advice on here a while back. Can anyone help this time?
Overview:
Potterton Puma 80 PP version. It's had a new diverter valve, but continued to play up, (Lockout at random). I replaced the TC which seemed to fix the problem. Of course, it was warm weather and I didn't check the heating. The HW now functions perfectly, (since the new TC), however.......
When the Central heating is selected, the bolier fires up and then locks out within a minute every time. The Pilot can be reset after a few minutes.
(I'm thinking pump, or some feedback circuitry prob)???
Any help, tests or advice would be appreciated.
Many thanks
Ben
