Wiring Aprilaire to Goodman furnace
My brother and I installed a Goodman GMH95 furnace this summer and now I`m trying to install an Aprilaire 700M. I can`t figure out how the wiring is supposed to go.
The aprilaire came with a transformer. I assume the black and white wires coming off the back wire directly to an outlet. The two screws on the other side are 24v, I assume. From the humidifier is two brown low voltage wires. One goes in to the humidistat. Where does the other one from the humidistat go? To the transformer or to the common on the furnace? My furnace manuel says to take the yellow wire off of the blower pressure switch and to plug in a supplied brown wire and use a jumper to piggyback the yellow wire onto it. Does the brown wire off of the pressure switch go to the transformer or the the other wire from the humdifier? I`m totally confused.
Please help so I don`t blow the board on my furnace!!
I attached a link to a pdf of the wiring diagram. Mine is the 700M. http://docs.electronicaircleaners.co...stallation.pdf
Thanks in advance.

You got a simple hook up.
The wire off the pressure switch goes to your humidistat.
The other wire off the humidistat goes to the humidifier.
Other wire off humidifier goes to C on the board.
The Transformer won't be needed.
