Thanks for sharing, I have read that before. Under the section "powered
flow through humidifier there is an update for powered flow through
humidifier with internal fan relay which is what i have. I wired it per
their diagram with no additional relay...
the humidifier is an Aprilaire 700 m attached to the cold air return.
One wire is attached to the * terminal on the thermostat and the other
to the “c” terminal on the furnace
