Potterton Performa

[Mr Smyth]

Can anyone tell me if the Performa has a pump overun? I'm sure it should but I can't find it in the MI's and I have been working on one today that doesn't (pump overun, that is)

Hope you can answer my question

Thanks

No pump overrun

Too many to list, but most don't.
The 'Instants' do have pump overrun, eithier 30 seconds or 3 minutes if room stat is still calling and boiler up to temp.

Check the M.I. for the model concerned and go to fault finding, first section should be on correct operation, follow this to the end.
