Product Overview

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.

This should work fine. There is no compatibility table.

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.

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

Answers

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.

First, remove the dial by gently pulling. Then you will see a screw. Remove the screw and the plate will pull right off. You may want to cut off power to the switch. If you have further questions, contact our Technical Support Department at 888-336-6151. Thank you.

The DH100W is a humidity control, not temperature. It is variable from 20% humidity to 80% humidity. It should be set at a level at which you are comfortable.

yes, mine is hooked up to a.c. but you have to figure out wiring ..i.e. in series or parallel .

There are black, red and green wires for humidistat wiring. What each wire is for?

This unit is basically a switch, green is ground, black is power source (usually black) and red connects to load (whatever needs to be power up, ie fan)

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.
