Customer Question

Control board shows "Pro" not a conventional error code. I need the boiler operating to make hot water now. Do I need a technician to reset or can I do this myself following Part 12 Start-Up procedure in the Boiler Manual? I am accustomed to annual cleaning (de-liming) and periodic cleaning of the rectifier probe to clear faults.
