I just got an Aprilaire 700 automatic humidifier for my Arcoaire N9MSB that has a 24VAC connection for a humidifier. I cannot find a wiring diagram on controlling the humidity with the Nest. I've found them using the provided transformer Aprilaire provided. I should be able to bypass using that and have the humidifier trigger off the furnace board. Or am I better off just letting the Aprilaire humidistat control everything?
