Question about Aprilaire 600 Humidifier
I have 24 volts going into the controller, the light is on.There is no power coming out and telling the valve to open. If I hook those wires directly to the selnoid valve it does open. (So it does work)
The only humidity/temp sensor seems to be part of the controller in back or the board and in the air duct.
Any one have some suggestion?
Hook one wire to the hum screw on the board if there is not a hum screw hook it to the green screw,go up to the humidifier then back down to the common screw on the board that should make the unit only come on when the fan is running. it sounds like the humidistat is not working correctly
