I have a MegaFlow system, pump fed for HW and CH, gas boiler that wants to run constantly. Controller off (even removed from back plate) and the demand is still there. Pump is running v/v is open and boiler fires up.?
Everything seems intact. Re-established Air gap in MegaFlow, system bled all round, room stats all checked, controller changed for new one, still doin' it.
Thoughts?
