New boiler, not long back.
I didn't think it was doing too well so bled the radiators. #Then no heating whatsoever!
"Low pressure" it said.
"Call installation engineer".
Yeah, right, I love paying for call-outs.
Then I found the handbook and pictures of the digital panel!
Troubleshoot: Press A and B for three seconds.
Low pressure: Open valve A then valve B, when pressure is 1.2 bar close B then close A. Bleed radiator 1....2....3.
Every time the pressure went below 0.9 bar there was a beep, beep. beep. Open valve A then B.......
This went on till all eight radiators were done.
I am warm and cosy now, but the old boiler was so much simpler.
All I had to do was tell her to light a taper...
OK, I'm off to the step...
