How accurate will the humidistat be if I mounted it on the return duct if everything is in a tiny closet or would I be better off installing that on the wall outside of the closet?Ĭan someone please explain how I am to wire this all up with this existing setup? I can provide a wiring diagram for the furnace if needed. The Auto thermostat setting is provides the temperature drop across the evaporator coil needed to properly remove humidity in the air. Why is there a wire occupying the HUM terminal already and can I use this terminal to wire my new humidifier?Ĭan I use the existing outlet and do I need a transformer to plug into the outlet? Insiders Tip: If your heat pump is not removing enough humidity from the air, check your thermostat to be sure the fan is set to AUTO and not ON. Power is being supplied to this outlet from the main breaker box in the home. My number one pick for the overall best whole house furnace humidifier goes to the Aprilaire 400. I also have a one outlet box with switch on the right side of the furnace below where I plan to mount the humidifier. The black wire from the hot HUM terminal goes to a box on the left side of the furnace. The Neutral side of the board has the HUM terminal empty. I have the proper terminals on the hot and neutral side of the board of my furnace (Trane XL80) but the hot HUM terminal is already occupied.

This lowers indoor humidity levels and improves indoor air quality. During the cooling cycle, heat pumps remove excess moisture in the air via condensation. OK kids, just bought an HE360A and want to avoid using the sail switch. Yes, one of the benefits of a heat pump is its ability to remove humidity from the air inside a home.
