Arrived on time, works as expected
I am using this to control a crawl space vent fan. It works fine, but the percent humidity reading is off by about 10 percentage points. Otherwise, good product and I would have given a 5 star except for the reading being off, which cost me some time fiddling around to figure out the offset so I could get the actual humidity in the crawl space where I wanted it.

I would NOT buy this again
The setting on the humidity dial is off by about 20 or more.
The TJERNLUND is a MUCH better unit all around.

I just purchased a eliminator humidity control Model EDH-1 and an Eliminator foundation vent fan Model : EL=1R.
My question is do I ALSO need a thermostat, and can provide with the correct thermostat compatible with these two units.

Product was as listed, I was surprised since I am a Novice.
Product was easy to install which sort of threw me for a loop since I find a lot of things that look easy are indeed hard and meant for professionals.

Great Product at a good price
Everything was exactly as advertised and it works well with the fan I bought separately.

Works Great!
This unit was very easy to install, it comes with the electrical box as well which makes it easy to install in crawl space.
The only negative I would give is the box it comes with is not very deep so you have to make your connections carefully as the Humidistat switch takes up a lot of the space in the box.

Q: What is the differential? How low below the set point will it turn off?
Asked by Stephen 2 years ago
Add your answer
Verified Reply- SupplyHouse StaffHi Stephen, thanks for writing in. This dehumidistat activates the fan when humidity exceeds the determined setting (20% - 80%) in conjunction with the built-in temperature control.

Q: Using it in a crawl space, where would the proper place be to install it? Would you want it in the center of the crawl space or near the fans?
Asked by Chris 10 years ago
Add your answer
Verified Reply- SupplyHouse StaffThe Dehumidistat control is able to be mounted remotely from the fan unit. It is recommended to install it in the area of the crawlspace where moisture is likely to first accumulate in order for it to activate the fan.

Q: What is the maximum ambient temperature rating of this dehumidistat? Planning to use it in the attic in south Texas to control the attic fan. Temperature in the attic are easily reaching 135-140 deg F
Asked by D 10 years ago

Verified Reply- Supplyhouse StaffI would suggest using an attic fan control not a dehumidistat, like the ones below: http://www.supplyhouse.com/White-Rodgers-775-1-Attic-Fan-Control

Q: Can 1 dehumidistat control be used to turn on multiple crawlspace vent fans? Thanks

Yes. I used it for 4 fans. To be sure, add up the amps on all your fans and make sure the total does not exceed the amp rating of the dehumidistat

Q: Do I need a dehumidistat control for each eliminator fan?
Asked by 15 years ago

Verified Reply- PexSupply StaffNo, it is an optional component to operate the EL-1 or multiple units.

Q: What is the Amp rating for this dehumidistat? I was wondering if it could be used with a dehumidifier that draws 5.1 Amps?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe manufacturer has tested this product with a maximum amp draw of 5 amps. They do not recommend using it with a higher draw than that.

Q: Will this product work during very cold weather (from below zero to 40 degrees above zero F)?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThis product is not affected by temperature since it is only a switch. The EL-1 fan that is used with the EDH-1 will not operate in temperatures below 50° F.

Q: I just bought this product and had it installed with the eliminator vent fan. I would like for the vent fan to run when the humidity is high under my house, but not run when it is raining because I don't want the vent fans to pull in more moisture. Can someone please advise what setting level I need to put the dehumidistat on so that the fan will run when its moist in the crawl space, but not when it's actually raining?
Asked by Robin 16 years ago
Add your answer
Verified Reply- PexSupply StaffThis unit is not powerful enough to pull in moisture when it rains. As far as which setting level to set it at, we recommend starting at 35 and make adjustments according to the humidity of the area.
