Have an Aprilaire 700 on my furnace. One more thing which you may not have noticed in the installation directions. If you want to achieve the maximum output from the humidifier, you should connect it to a hot water line instead of the cold water line. Have mine connected to the cold water line and have not seen any issues in reaching set point.
Thanks again for all the help. So in summary for anyone else who may stumble across this in the future:
Model 700 Fan powered Humidifier (Gray Color not Almond this makes a difference)
Used Hot water line to humidifier.
Connected 110 cord to 115 15Amp outlet.
Connected the humidifer brown wires directly to the HUM and 24VAC common on the accessory terminal with no relays. (HUM measered 24VAC)
Connected the outside temp probe to the Bryant Furance OAT terminals.
Furnace is a Bryant 98M Evolution Series with a Bryant Evolution thermostat.
Humidifer is a Aprilaire 700 (grey) with Model 60 controller that I didn't use.
