Geoffrey on a rsf 240 is it possible for the pump overrun if faulty to fire the boiler continuously. Had one today all external controls disabled and boiler firing. Had 240 on lr and on both frost stat connections but no controls connected. I assumed pcb but someone reckoned the pump overrun stat if faulty could do this.
