The Aprilaire Automatic Humidifier Model 500 is the economy version of the 600 intended for use in smaller homes. It takes humidifier innovation to the next level and performs as good as it looks! It offers all of the performance benefits of Aprilaire's more advanced humidifiers including Automatic Digital Control which automatically adjusts humidity based on outside temperature. The Aprilaire 500 is easier than ever to install because it includes a built-in bypass damper, which means fewer parts to install. Plus, the damper is conveniently labeled for summer and winter settings, allowing you to set it for the entire season with no guesswork involved. This humidifier can be installed on the supply or return air ductwork. It is also left or right side reversible. Includes automatic digital control humidistat, sensing bulb, water pad, 110v to 24v transformer and manufacturer's special instructional DVD.

Automatic Digital Control Features

  • Shows that the humidifier is operating
  • Allows you to check relative humidity level
  • Tells you when it's time to change the water panel
  • Gives you service alerts

Other items needed for the installation that are not included: 1/4" copper tubing for water line, 1/2" ID plastic tubing for drain, 6" round ducting & elbow for bypass air, 2-conductor 18 to 22 gauge wire. These items are available in our easy installation kit.

 

Type

The two main types of standard humidifiers are the bypass and power fan.

Bypass humidifiers can be installed on either the supply or return plenum and you run a bypass duct to the plenum the unit isn't installed on.

Power-Fan humidifiers can be installed on a vertical run of either the supply or return plenum and uses a fan to distribute humidity into the air stream.

Type
Bypass
Maximum Coverage Area

Maximum Coverage Area
3000 Square Feet

Electrical Requirements

Remote Sensing Bulb

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.
