Can someone tell me what the Cylinder SG Humidifier Full interface does in the humidifier section? It looks like the Mars delay on make timers I carry on my van.

After the water fill valve closes it will open and close repeatedly in 1/2 second intervals anywhere from 5 to 10 seconds. If I unplug a one of the coil wires while it’s doing this it stops.

Just not sure how that humidifier full interface operates. If anyone has come across this same issue Im open to suggestions too.
