This is awesome. I used mine and ducted it through the floor of my older mobile home into the insulated frost box to prevent my plumbing from freezing up over the winter I live here in Maine. I put the temperature sensor down through and away from the duct to get a cold reading at the furthest point away and set it at 40°. It runs for 5 to 10 minutes every half hour on level 1 speed which is the lowest speed setting, you can't even tell if it's running or not. The video will show my configuration which if this works on the coldest days I'm going to put a hole through the wall with collars to make it look nice and neat and I will mount the controller on the wall as well. I connected my phone Bluetooth you must download the app and if you're going to do Wi-Fi so you can check it anywhere that you are work, shopping away ETC you have to put it on 2.5 GHz. This was pretty easy to figure out if you have moderate technological capabilities. The manual is good and the reference cards are fantastic as well. I give this five stars all the way a multitude of uses from growing to pumping warm air underneath a mobile home to keep pipes from freezing on frigid nights. I highly recommend this product. I feel much more comfortable with this blowing a little warm air down there than having heat tape and light bulbs and space heaters,not very safe. I now have better nights sleep that's for sure and not to mention I have all the data temperature humidity ETC available on my phone at all times.

5.0 out of 5 stars Effective and Well Priced
Reviewed in the United States on March 2, 2022
I purchased this fan to exhaust warm air from a home theater equipment rack. With all the equipment turned on, the temperature in the rack quickly climbs to over 90 degrees. The equipment rack is recessed into a closet under a set of stairs, so goal was to activate the fan to pull warm air out as soon as the temperature rose to 80 degrees at the top of the rack. With the controller, it can be set to automatically and progressively increase fan speed after the temperature hits the target. Every 2 degrees after the target the fan can increase speed by 1 step.

PROs:
> Very quiet at fan speed 1 and 2. At 10, this fan pushes a lot of air.
> Controller allows multiple control options - I just needed the high temperature option
> Easy to install with the mounting plate - I got this mounted and installed in under 30 minutes.
> Fan direction can easily be changed. The fan module just pulls out and you can change airflow without uninstalling - this is great to test whether pushing cold air in vs. pulling warm air out works better for your application.
> Nice long temp/humidity probe and cable let me place the sensor exactly where I needed it.
> Ability to place the controller wherever you want it as well.
> Works seamlessly with their matching 4-inch flexible ducting, and wall mount duct grille.
> Comes with two duct clamps
> High quality construction -- strong mounting bracket, and thick plastic casing.

CONS:
> At speeds between 3 to 10 you definitely know it is running, though it is probably quieter than other fans.
> I have this mounted to a wood support. At high fan speeds the motor vibration does reverberate through the wood supports - so need to play with how to isolate the fan if noise is important.
> Controller settings are very complex given what you would typically want to do. To set the fan to turn on at 80 degrees and increment speed in steps as temps rise took a bunch of menu hopping and instruction manual reading -- not intuitive. In contrast this was a very simple setup on their AIRCOM fans.
> Don't like the fact that in AUTO mode, multiple sensors can affect whether the fan turns on... Took a couple days to dial it in. High temp, low temp, high humidity, low humidity... hard to predict when the fan will turn on... I get this is geared for agricultural use, but setup is more complex than it needed to be.
