Our Aprilaire humidifier was reinstalled on our new dual fuel system. I've been told that it can be wired to come on 3 ways. One is with the fan, two is with the hp, and three is with the gas. I don't want to energize it with the fan because I want to leave the fan (vspeed) on to circ the air for our 3 levels to even out temps even tho we have 3 zones now. The hp is what I'll use the most in the NC, so I had the humidifier wired to that.
Is this the way it is? I'd rather have the humidifier come on with a call for heat.
System is trane vspeed fan, hp and gas, honeywell tz4 zone board.
