No storage with boiler. We seem to get slot of air. Also our plumber has set the damper temp to 375 but the books say 700Hmmm i haven't had any alarms since i went to the new controller
Can you post a picture of you controller?
The install went well? All pressure tested and air removed?
Are you running storage with the boiler? Could you also post some pictures of your piping and other parts of the system?
More info will help getting help on your issue.
