Hello, we have a Bailey Net90 system used for BMS on a boiler. We’ve encountered issues with header valves cycling open and closed while the boiler is running. We have 4 burners on this boiler and the valves cycled with 2 burners on and 4 burners on etc. We ran the boiler and had a rep come in to diagnose and saw no issues.The issues have occurred on the off hour while we were not present. Has anyone encountered and issues with this? We are suspecting output boards (for 110 VAC rated solenoids). It’s hard to troubleshoot when all looks healthy out in the field. Weather wise the problems occurred on dry days, no rain.
We’ve replaced output boards and rep performed resets on the individual burners and header logic boards.
