About the Manual Control:
The H8908 humidistat is your basic, bare bones control.  It's advantages are simplified control and low cost.  It closes the humification circuit manually whent he humidity drops in the home.  This humidistat will not  provide any automatic control based on outdoor temperature.  It can be mounted on the wall or on the return air ductwork.


  • TrueSTEAM works by producing its own steam independent of equipment operation, so your home gets moisture when you need it most.
  • TrueSTEAM is the most eco-friendly way to humidify your home, because it uses up to 70 percent less water while delivering more moisture than traditional whole-house humidifiers.
  • While other humidifiers rely on moisture-filled pads that can be susceptible to bacteria growth in the water and the airstream, TrueSTEAM delivers "true" steam - the cleanest form of humidification.
  • In addition to keeping your home and family comfortable, TrueSTEAM can help reduce heating bills. Because humidified air feels warmer, you'll be able to turn your thermostat down for savings.
  • Installs in minutes - Limited duct cutting and bracket-mount design takes less than 5 minutes to complete.
  • Easy maintenance - Self-regulates cleaning cycles throughout the year. Annual maintenance requires no tools to access and clean, saving time and money on annual contractor service calls. In-line water filter for scale and sediment also provided.
  • Application flexibility - Mount directly to the duct or remotely (with optional remote install kit) up to 20 feet away into tight-fitting or unconditioned air spaces.
