Aprilaire 700 power humidifier (formerly Model 760 and 768) features truly automatic control called AutoTrack (like the 600), so there's no need to ever manually control the humidifier.
It is also designed with ease of service in mind. It utilizes an outdoor temperature sensor for monitoring even the slightest changes in outdoor temperature.
This high-tech humidification system can deliver up to 50% more moisture in comparison to competitive units. With flexibility in mind, it can even be installed in manual mode if necessary. Complementing any HVAC system, the 700 has an evaporation capacity of 0.75 gallons per hour, among the highest capacity humidifiers sold.
If you own a larger home and want the best, then this may be the humidifier for you, as it will handle up to 4,200 square feet if your home is tight in construction. Includes humidistat controller, sensing bulb and water pad.
Plenum opening size is 14 7/8W x 14 3/16H

Drain Connection: 1/2 inch I.D. plastic hose direct to drain fitting on unit

This unit includes a built in 110v to 24v transformer.
Other items needed for installation that are not included: 1/4" copper tubing for water line, 1/2" ID plastic tubing for drain, 2-conductor 18 to 22 gauge wire The Aprilaire 700 should not be installed on horizontal flow ducting.

Maximum Coverage Area 4200 square feet Maximum coverage area means this humidifier will perform well for home sizes up to the square footage indicated, provided that the home is “tight”. A tight home is typically is one that is sealed well around windows and doors and does not leak air to/from the outdoors. Note that humidifiers will perform well for smaller homes as well since the controller regulates the amount of humidity automatically to adjust to home size.
Width 15 29/32 inches
Height 15 31/32 inches
Depth 10 11/32 inches
Electrical Requirements 24 and 110V Humidifiers with 24 volt AC electrical requirements obtain such by connecting to either 24VAC from the furnace, or by adding a transformer to the furnace to create such.
Most installations can use the 24VAC that is already accessible in the furnace.
Humidifiers with 110 volt AC electrical requirements simply plug into a standard outlet (receptacle) and require no special wiring for this part.
It is recommended, however, that the outlet/receptacle be dedicated for the humidifier, and that it can by shut off by the same power safety switch that turns off the furnace. Warranty 1 year(s)
Type Power-Fan There are two basic humidifier types: bypass and power fan. Each simply uses a different method to move air through them. Power fan humidifiers use a 110 volt fan to move air through them. Bypass humidifiers do not have a fan, but instead require a 6” duct to be connected to the side and then to the opposite air duct system from the humidifier.
That means for bypass models that if the humidifier is installed on the supply plenum, the 6” duct will connect to the humidifier and the return plenum, and if the humidifier is installed on the return plenum, the 6” duct will attach to humidifier and the supply plenum.
Humidifier types: – bypass and power fan – will provide the same benefits to you. The only difference is the technology used to do so. The advantage to power fan models is since they do not require additional ductwork, they can be installed faster and in tighter spaces.
The advantage to bypass models is that they cost a bit less.
Remote Sensing Bulb Included A remote sensing bulb is a small (about ¼” round) sensor that mounts outside the home and connects by light gauge wire (18 to 22 gauge, 2-conductor) to the humidifier controller.
This sensor provides temperature readings to the computerized controller which allows the humidifier to automatically adjust humidity levels in the home based on outside air temperature.
Aprilaire brand humidifiers include a remote sensing bulb in the box with the purchase. Honeywell brand humidifiers do not include remote sensing bulbs, but offer such as an additional purchase option. Both brands allow for humidifier operation without the use of the sensor should you choose to not install such.
