Perfect match

Works great with controlling my 1,600 sq. ft. basement humidity. Connected to a powerful Honeywell DH90. Highly recommend this combination.

As advertised

Good value, turns fan on and off. Have not checked accuracy, but not critical for my application.

Automates bathroom ventilation

I have installed FH20 Dehumidistats and exhaust fans in both of my bathrooms to control humidity. The fan switches on automatically soon after I begin a shower and continues to run after I leave the room until the bathroom relative humidity returns to the normal level set on the dehumidistat. The setting requires only occasional adjustment to accommodate higher than usual ambient humidity (weather changes). Much better than a manual switch, which may or may not be used when needed. The fan runs only when needed and shuts off automatically when humidity returns to normal.

Works great !

This product works great for me. Installed the dehumidistat in our bathroom, hooked to fan. No need to concern ourselves with humidity from taking a bath anymore. I have no negative comments to give about it.

Q: I installed this dehumidistat in a crawlspace to control a ventilation fan. So far, the fan is running continuously, even on the highest (80%) setting. What are possible reasons?

Q: Can I use two dehumidistats (one for each bathroom) to control one central exhaust fan? Is it possible to connect two devices in parallel?

Yes, these can be wired in parallel to control the exhaust fan.

From the controlled circuit's perspective, they are basically on/off switches. They can be paralleled. Either one above it's' setpoint will turn on the fan.

I can't imagine this would be a problem but suggest confirming with manufacturer.

Yes, you can connect 2 dehumidistats in parallel to control a single appliance. Be sure not to wire them in series - that will not work. -------- Original message --------

I believe you can as long as you are supplying power(black) directly to the exhaust fan and you are using the dehumidistats to each connect the fan up to neutral/return(white).. If you can't do that you need to make sure the highside has the same 110V phase. If you don't do this, when both humidistats are switched you'll be shorting 220 through the humidistats and likely just blow a breaker, if you are lucky.

Q: Can I use this in a reverse application? I only want to move air when the humidity is low. Can I program a range of operation or does this just go from high humidity to low?

it will not work

The device is a simple switch that is closed when RH is higher than the setpoint. You would need to use the switch to control another switch that is normally closed (running a fan), and would open when the rh gets high enough.

You can use it with a line-voltage fan. Please refer to the link below for more information. http://s3.pexsupply.com/manuals/1265897172813/25658_PROD_FILE.pdf

Q: Before I buy this, I want to know if this will prevent mold and what setting to use during the summer when I am not in the house

According to the manufacturer, if you used this product with a fan it would help prevent mold. It is a dehumidistat so it will turn the fan on or off at certain humidity levels. The fan itself is not going to take any humidity out of the air, so it may run continuously if you set the dehumidistat low enough.
