Inkbird Humidity Controller IHC200 Humidistat Mushroom Greenhouse Pre Wired Outlet Dual Stage Humidifier Dehumidifier

I have bought several IHC-200 controllers for use in a greenhouse. They work well, except one had a problem with the display. I contacted customer service, got a response within 24 hours asking for a video to demonstrate the problem. I sent the video and the next day they said they would ship a replacement. The true test of a company is how they respond when something goes wrong, and Im satisfied with their response in my case.

Definitely a game changer! Used for legal medical grow tent environment control along with humidifier/exhaust fan & it beats hanging wet towels every couple hours. 3 stars on accuracy because im not sure. I also use a simple digital temp/humidity gauge along with sensor supplied with this controller & theres variances between the two but I take into account the differences between the 2 devices. Which one is more accurate? I make it work. When things are leveled out they are pretty close.

It works great! Watch YouTube to set it up.

You can make it work as long as you want to maintain a very narrow humidity range. For instance, when the humidity is maintained at 50% +/- 5%, you can get the device to read fairly accurately by using the calibration function and adjusting for the difference between actual humidity and the humidity that the probe detects. But when you want to maintain a humidity of 65% +/- 5%, you have to go through the calibration process again because the probe is not linier. It is way off. I will contact the company and update this review later. Ive had this device for about a week now and I contacted Amazon for assistance. A day later I received an email from the manufacturer asking for details about the lack of accuracy and linearity. They gave me instructions that allowed me to clear the internal settings and then reload the settings, by pressing the buttons in a special sequence while unplugging the device. It worked wonders and the device is working fine. Great support from the manufacturer and Amazon.

The instruction manual is very hard to understand, obviously written by people for whom English is a second language. But, once you get past that, it works beautifully and seems very accurate. The display is very easy to read.

great product, a bit hard to setup all the features, but once you do it is fantastic.

The high alarm cant be turned off, so if your using it to regulate humidity above 80% without a dehumidifier, the thing doesnt stop beeping. Not the best

Works like a champ once it’s programmed. Had to search for a video because the instructions are not idiot proof.

For years Ive been disgruntled at purchased de-humidifiers and their lousy humidity control. The sensors in these products are sloppy at best and often fail over time. The key to this controllers effectiveness is the very accurate sensor itself, the rest is just common sense digital control. The available options and settings for controlling the dehumidifier are top shelf! This also works with humidifiers so am looking forward to doing some testing this winter. I FINALLY know exactly what the humidity level is in my basement and rest assured my power consumption to maintain my desired humidity is minimized. (you can even calibrate this controller if you have a known good dry bulb kit or similar) Yes, the set-up is somewhat confusing, but if you have a basic understanding of humidity and hysteresis settings, its a breeze, and easily adjustable at any time you desire. For the price, this is an amazing control, and I would highly recommend it to anyone wanting better humidity control in any environment. Ive had it running for a month now 24/7 with no problems.

My dehumidifiers humidistat stopped working. So dehumidifier was either running all the time, or off. I looked into replacing what was needed and it didnt make sense... too much hassle. For less money, this did the trick, I have the humidifier set to high (dry) and set the controls on the Inkbird to where I wanted. Works fine. The controls arent very intuitive, and some things arent marked as clearly as they should be, but take your time and youll figure it out. The humidifier now holds humidity to right about where I want it.
