## Questions & Answers

**Q: Give me an example of your temperature settings?  I’m confused on how to set it.**
A: There are three settings that can be adjusted: Fan speed, Cooling Temperature Threshold, and Heating Temperature Threshold.  The manual recommends only having the heating OR cooling thresholds set at one time, but as long as you keep a large enough temperature differential between them you shouldn't have issues.  If your room temperature is currently 72 degrees, and you turn on your AC you would want to set the cooling temperature to something like 65 degrees.  This way, when cold air from the AC begins to pass through the vent, the displayed temperature will begin to drop from 72 down to 65 degrees and below (because the air from AC is much colder than 65).  When the vent registers the temperature is 65, it will kick the fans on for all temperatures colder than 65.  The fans will stay on until enough time has passed when the AC is off that the temperature gets warmer than 65.  Likewise for heating, you would want to set a temperature like 80 degrees, so that when the heater begins blowing warm air and the vent registers that the temperature has raised, it will be on as long as the temperature at the vent is warmer than 80 degrees.

**Q: Will this work well with a geothermal system that does not output as extreme temperatures as a traditional gas/electric heater?**
A: Yes. I have a geothermal system (WaterFurnace), and haven’t had a problem with the unit starting when heat kicks on. It’s made a noticeable difference in the room (furthest from furnace) where we are using it. Well made unit, impressive packaging.

**Q: Can it be used in the floor where it might be stepped on?**
A: It is very sturdy, but if you step on the digital screen and buttons it may crack. Also, wouldn't recommend placing in a traffic area because of the cord that runs to wall outlet. Really solid system.

**Q: Do you have a version of this for a baseboard unit?**
A: No

### ⭐⭐⭐⭐⭐ Made a huge difference in my room temp
*by L***S on August 16, 2023*

The media could not be loaded. (Update 8.3.2024)One complaint. Because the new Bluetooth display goes in 0.1 increments (e.g. 64.9, 65.0, 65.1), the fans tend to rev up and down several times before settling in and remaining on. This makes it kind of distracting and often wakes me up because it goes up and down before remaining on. Other than that still a tremendous value. Maybe the makers can release a firmware update that has the temperature going in straight number increments instead of 0.1 increments.(Update 06/14/2024)As of this date, they still can't vouch highly enough for this type of product. Through the winter it kept my rooms warmer where needed, and during the warm months kept my rooms on the second floor much cooler than without it. I recently purchased another one a couple of days ago because it had a 25% discount. I actually ended up getting a different model that actually incorporates Bluetooth and an app. That just made the value of this product jump up quite a bit. It's model AC-RBF4-W. I'm wondering if it's brand new in the model lineup because I can't find documentation on it anywhere, but so far it's been actually really nice having Bluetooth connectivity so that I don't have to go down to floor level to adjust any settings if I wanted to. Plus it's nice to see what the temperature in the room is without having to get out of bed. Super lazy person here lol. Anyway, if you're on the fence, I can honestly say they've been worth it. Still happy with them and ended up buying four more after my initial purchase.(Original review)What I like:1. Works very well2. Easy to configure3. The digital display4. Easy to understand directions5. Can turn off the display once you've set it up6. Relatively quiet at lower speedsWhat I don't like:1. It's a little pricier than other brands, but so far it's been worth it.First and foremost, for those who say the temperature settings either don't work or are backwards, it's just not true. Yes, you very well could have gotten a defective unit, but the vast majority of complaints are unfounded and rooted in ignorance of the function of the product.It is NOT a thermostat! It has a thermal probe that registers the temperature of the air coming from the vent. Therefore, if you want the product to push cold air during the summer, you want the fans to kick on when the temperature of the air coming from the vent is at or lower than the temperature preference you set. For example, my room routinely got as high as 78°F during the summer, so I set my cooling trigger to 72°, so any air that is that temp or below will be pushed into my room. My room now regularly stays around 72 degrees.Now the opposite will be true during the winter. My room can get very cold. As low as 55°. That's freezing in the winter time. So I set the heating trigger to, say, 75°. That means any air coming from the vent that is that temp or higher, will turn the fans on to push the warm air into my room, thereby making it warmer quicker.Hope they helps those who have trouble understanding what the unit does. Just remember, it's NOT a thermostat.

### ⭐⭐⭐⭐⭐ Best. (Small) Investment. Ever.
*by C***N on September 2, 2024*

Our master bedroom is the furthest room from our central A/C. Due to the awkward layout of our cookie-cutter home, the lone vent that serves our bedroom snakes through 4 90s and transitions from sheet metal to flex, to sheet metal, and back to flex again as it goes through 2 separate floor cavities and up through a 2x6 interior wall.Long story short, it has never had adequate airflow to cool our room, especially during the 100°F+ dog days of summer. We already have a ceiling fan which does help, but it mostly just blows the warm air around the room.In the past, I've just run our central fan A LOT to continuously move air through the bedroom. Problem is, that means the central fan is always running circulating air through the whole house for the benefit of just 1 room. And running it all the time increases our power bill up by around $50/mo.Then I saw these vent boosters and thought "what if I used a 6 watt booster fan 24 hours per day instead of running our central fan almost all the time to see if it will achieve the same results?"Well I'm here to tell you, THE RESULTS ARE EVEN BETTER! I have the vent fan set to run full blast, 24 hours per day. And our room has stayed 8-10 degrees cooler than before, even through a record number of consecutive 100°F+ days this season. Since it keeps running when the A/C is not, it keeps pulling cool air through the cool evaporator coil even though the main fan is off. So the air it pulls through almost never even hits 70°F on the vent's thermostat. What's even better? Despite all those additional days of extreme heat this year, my power bill was about $50/mo less than previous years for the same months! So it paid for itself in a single month!So is it noisy? Yeah, a little, especially on the highest settings. But I can comfortably watch TV at a normal volume right next to it at a setting of 7 or lower. And since I sleep 5 feet from it, the Bluetooth app makes it really easy to adjust when we're in the room and need it a little quieter. We actually like the noise on high while we're sleeping, the white noise helps us sleep better. I leave it at a 10 at all times if I'm not trying to watch a show next to it.Conclusion: if it seems like this vent fan may be a good idea for a room that won't get cool or warm enough depending on the season due to an inefficient central air system, it is. Buy it today. You won't regret it.Sidenote, I'm in IT and I've used other AC Infinity products to cool expensive and important data equipment for a couple years now. They're all excellent. Better quality, quieter, and more useful features than units that cost 3X as much. This company knows what they're doing, and I can't sing their praises enough.
