Size:  12.4 KBI’ve seen posts on here about this but still can’t figure mine out. Installed an Aprilaire 700m on my system last weekend. Ever since then, my humidity level is 48-55% when I’m only calling for 36%. Water drips out of the drain tube anytime the furnace is running. I’ve attached photos of the wiring. Any help would be greatly appreciated.

Welcome to the forums.

Take the two brown wires off the HUM terminal, connect them together and cap with a wire nut.

Right now the furnace is controlling the humidifier. With the wires removed from HUM....the Ecobee takes control .
