Troubleshooting Aprilaire Humidifer Wiring
I checked the wires at the solenoid, no reading. Th transformer has a 24VAC hub and a 10VAC hub (printed directly on it). The installation instructions state to: "connect the 24 volt side of the transformer to one of the H terminals on the hum control and to one of the solenoid valve wires. Connect the other solenoid wire to the other H terminal."
See attached pictures. The first shows the two terminals one on left is stamped 10VAC one on right is stamped 24VAC. I have both wires connected to the 24VAC side as the instructions read (or at least how I interpret them)! Second is just model info on the transformer.
