Hello! I'm looking for some help connecting my humidifier to my thermostat and I have an NCM-300. I have attached pictures of my setup. I have a red and white wire at the thermostat where my old humidistat was. I know I only need 1 wire there but I'm not sure if I need a relay or what would work.
Specs:
Furnace: Bryant Plus 90i
Humidifier: Aprilaire 560
Control Panel: NCM-300
Wifi Thermostat: Bryant Housewise

You can hook the humidifier to the furnace control board. This connection will start the humidifier every time there is a call for heat by any zone.The control board has a terminal marked, (HUM) for humidifier. You will use thermostat wire, one wire from the HUM terminal on the furnace control board to the "R" terminal on the humidistat controller, the other wire from the "C" on the humidistat controller to the "C" terminal on the furnace control board.
