Product Details

The DH100W white dehumidistat is a control switch which operates a connected fan based on the relative humidity it senses in a room. A user can set the desired humidity level and the dehumidistat control will activate or switch on the fan to ventilate the room once it detects higher humidity. The fan will remain on until the desired humidity level is reached, at which point the humidistat will shut the fan off.
  • Variable setting from 20% to 80% relative humidity
  • Fits single-gang box
  • Can be used as 120-Volt control or low voltage (up to 24-Volt) control applications
  • Recommended for use in rooms where excess humidity is a concern
  • Shop all Broan-NuTone Bathroom Exhaust Fans
  • For any questions regarding product features, installation, or specifications, please call our Technical Services Dept. at 800-637-1453, Monday-Friday, 8:00 am - 7:00 pm EST.

    Answer This Question

    A:  The DH100W fits single-gang box. if you currently have a single gane box that houses your switch, then yes.

    by|Mar 19, 2020

      A:  If you have a triple gang box I do not think it will fit properly. I doubt you can get a plate to cover the other two switches with this in place. You may be able to cut a cover plate to make it work but it would not likely have a good appearance and may not meet code. I think it needs its own single gang box. You may be able to mount a new single box near the device it is controlling and reroute the wires there and leave the existing switch in the on position at all times. Just my opinion. Mine works well. It is in the garage to exhaust excess moisture primarily when we come home with snow covered cars.

        Q:Will this work with A broan 270 cfm through the wall exhaust fan model 508?

        Answer This Question

        A:  Yes, it will.

        by|Jan 28, 2020

          A:  It certainly should. There may be other features on the fan that would not be activated with this, but as to turning the fan on when humidity is high and off when the humidity is lowered it should be just fine.

              Great Product!
              I will never get in the shower again and worry about the mirror being totally fogged up when I get out... I've wired this wonder switch straight up to my bathroom vent fan and it has taken all the guess work out of my daily hygiene ever since. I simply set the dial and let this thing be the co-pilot of my bathroom. The best part is within just seconds of this controller taking the reins, all the moisture is just...whooosh...gone! It just knows! I recommend this product for any person who has a bathroom in their home, you know who you are.

              Great product to turn on (and OFF) vent fan to manage humidity in basement. Easy to install. Fits inside an electrical box or can be surface mount - Clever. Now it automatically turns on my vent fan when set humidity level is reached. If the humidity falls below the set point the fan turns off automatically. Lowest price too among many options.

              The unit is way off, about 30 percent off calibration. Ruined many cigars inside controlled humidor. When humidor gauge was reading 65 % the humidistat dial read 30%. This major difference in humidity caused us to lose about $600 in cigars inside the humidor.

              After being installed a couple of weeks ago, our new humidistat appears to be doing its job well. Can’t ask for more than that.
