AC Infinity Controller 63, Wireless Remote Controller with 10 Fan Speed Programming, Cooling and Ventilation for CLOUDLINE Airlift CLOUDWAY Fans

Works great. Wireless. To control my booster for the basement heat

So the AC Infinity AI-CLA4 4" Fan Units come with a non-removal USB-C cable. The fan also comes with a controller that is smaller but functions exactly the same as the wireless version. However, my problem was that the two fans I purchased were in a hard-to-reach location. I decided to put a rheostat (basically a dimmer for motors) at the switch to control the speed of the fans that way. However, the range of speeds was horrible with the switch device. Therefore, my choice would be to use the hardwire controller. This was problematic as I would have to run these through many openings and then pull them back out if I had to maintain the fans or such.Enter this solution instead. You plug the included USB-C radio receiver to the hardwired cord on the fan instead of the controller that came with the fan and use this wireless transmitter from wherever you want. Two AAA batteries and you are off and running. On both the wired and hardwired, pressing the controller once lights one dot and the fan runs at speed 1. Rinse and repeat up to speed 10 (increasing by 10% speed each time). Pressing it again turns it off.Now for the extras! If you have the fan on a wall switch and you were running on speed 4 let's say, turning off the power at the wall, then turning it back on, the fan remembers your last setting and resumes (so in this example - the fans return to setting 4 (or 40% speed)). Better yet, I have two fans, and I bought two wireless controllers. I have an option of setting the controller and remote to the same setting or different setting (so I can control the fans together with one remote or control the fans separately with two remotes setting them at different speeds if I so desire.Highly recommended

I hit my original fan speed controller with my cabinet and broke it. Surprisingly AC Infinity let me know that they don't offer replacements. Feeling utter disbelief that I might have to purchase an entire new fan just because the speed controller broke, I went to Amazon and found this. Free overnight shipping was offered, and I bought it. To my surprise, it was plug and play by simply adding the 2 AAA batteries to the remote and plugging the other end into my fan. That's it. It just works. The remote even has a magnet built into the case that allows it to stick to the metal plate on their grow tents. I guess I dodged a bullet on this one by not having to buy another fan and it is a nice, unintentional upgrade to boot.

Batteries are good. ON works. Speed stepping works. OFF rarely work. Have to step through all 10 speeds to turn off.Not a range issue. Same problem with remote close to receiver.

Great plug and play upgrade. This little remote could control my duct booster from 2 floors away. I would buy again.

Just what I needed for a very loud cloudline blower I inherited without the original speed control. Works great to set to about half speed. And an economical choice

This is a must if installing the fan in the attic. No wires coming through the ceiling!

Even with central heat and air, our master bath was extremely hot during summers and extremely cold during winters. Contractors recommended repairs that would have cost thousands. My husband installed this fan unit (with it’s remote) inside the ductwork leading into our bathroom. We’re amazed at the results! We only wish he’d done it 5 years earlier!!!
