    Have you purchased your steam humidifier yet?
    I know EWC's Autoflow brand steam humidifiers will turn the system fan on themselves when himidification is needed, and isolate the call to the G terminal of the equipment from G on the thermostat.

    They also give instructions for how to set up a fan failure safety lockout.

    If more government is the answer, then it's a really stupid question.

    Thanks anyway.
    I'm an idiot and need your help, But I also want to be a smart a$$ with reply's like above. Take a jumper from R-C if you see a spark it will work fine..

    Yes you'll back feed the Y terminal to the outdoor unit.
    Check the vision pro stat, the 1 model has fan recycle ability, and may be just what you want.
