The 400 is a non-powered unit.. Did they run a wire from one of the R's down to HUM1, and then HUM2 to the humidifier? (other humidifier wire to COM)

The IAQ can provide power if it's wired up as above. Did they add an outdoor senor to the IAQ? (Don't have to have it, but it's nice to have... I have it on mine)
