Product Description

Aprilaire humidifiers provide maximum comfort throughout your entire home - every hour, every day, all season long, without the mess and inconvenience of portables. Heating your indoor air dries out your skin. This not only makes you feel itchy but can also make you feel chilly. This cold effect is not the only discomfort caused by too dry air. Annoying static electricity is another indication of low humidity levels. Proper relative humidity (rh) will reduce this discomfort.

Good Product, No More Room Humidifiers To Fill Up!!

Good Product, No More Room Humidifiers To Fill Up!!
It's a great product and it works extremely well when set to full automatic. The outdoor temperature sensor needs to be installed for automatic mode for proper relative humidity and to avoid window condensation. Yeah it takes some time to install it properly but well worth it. When it's set to automatic it will actually kick on your blower periodically even without a call for heat to get an accurate check of the humidity levels and stay on if they are low. The automatic mode helps tremendously after the heat runs and it needs to stay on for a bit to keep the levels accurate. I also found this setup to be useful in reducing cold spots in the house and to help maintain even temperatures kind of like a 2-stage furnace would. With a flip of a switch it can be set to manual and will only run if there is a call for heat and humidity is required. If you're going to spend the time to install one of these, I wouldn't settle for a unit that is not automatic. The 24vac transformer that was sent with the unit was pretty cheap; I tried to loosen one of the terminals and it broke the lead. Not worth a phone call so I just picked up one at the hardware store for $13. If you plan on using this for automatic purposes, then the transformer should be powered with constant power. I ran power down from the furnace power switch to the blower compartment where I mounted the transformer. That's also nice because when you shut down the furnace via the switch it also shuts down the humidifier and adds protection with the onboard furnace fuse. You will want to wire the transformer at the switch and not from any wires or furnace electronics after the switch (excluding a designed HUM accessory power lead). Like many others my furnace's Honeywell circuit board is equipped with a HUM accessory power lead and on my unit it is 120V so don't think you can bypass the use of a transformer if that's the case. But if your board is similar to mine the HUM power lead will only work if you plan on using it in manual mode as it's only powered when there is a call for heat; it is not powered when there is only a call for the blower or no call at all. Obviously the unit will be more efficient when supplied with heated air; as will be the case most of the time. But there are several studies that show a sufficient amount of humidity will be applied by just the blower moving ambient air through the unit. The manual does state that when set to automatic mode then the unit should be supplied with hot water and in general that is a good practice for the MOST efficient way to evaporate water and help keep the impurities from building up over time. But I couldn't justify the usage of energy that it takes to make that water hot and watch it go down the drain. Some studies show that the benefit is insignificant in supplying hot water over cold water. It's going to be up to you but I couldn't do it and the unit still works very well when supplied with cold water. Hope this helps some of you out in the decision process and I posted a few pictures of the install.
