I bought the AirKing rotating drum type humidifier from home depot and
installed it on my furnace today, however, something I found it's very
stupid by design. I set the % humidity to my desired percentage. However,
the humidifier is on even the heat is not on, the drum keeps rotating all
the time. It's waste of my electricity.

That's nothing, compared to the huge waste of heating fuel.
