My boiler pressure was at 0. So I opened the 2 valves underneath the boiler and the pressure went back to normal, so I turned the valves back to where they were. Now it is showing error code 5.30, I've looked it up and it says that clamp 3-4 open. Am I right in thinking these are the two valves that I just turned? I did try to turn them both again but that is just increasing the pressure! So I'm not sure what or where clamp 3-4 are?
