humming transformer on Honeywell HE360A
Just installed Honeywell to supplied H8908C dehumidistat. Connected one yellow wire from dehumidifier to black wire in dehumidistat and other black wire in dehumidstat to remaining yellow wire on dehumidifier. I am getting a hum from built in 24V transformer. What did I do wrong? The unit plugs into 120V electrical connection. Connecting yellows from unit together provides working unit but still get hum.
