Question about Aprilaire 700 Humidifier
If you don't have a volt meter, purchase one. I've seen them as low as $20.00 at Sears and even lower at Home Depot and other discount stores. The HUM terminals are most likely low voltage (24v). The "N" is the neutral. Assuming you have confirmed this is low voltage (24v, you will use HUM and "N" terminals. This control sequence is typically to allow for operation of your humidifier only when there is a call for your fan to run. The brown wires coming from your Humidifier are your low voltage circuit. One should be directly wired to "N". The other should be ran to your humidistat. The other side of the switch of your humidistat should be wired to the HUM terminal.
I hope you will find this helpful. Good Luck!!!!
