For our location in southern CA summer, we have low set for 75, medium for 90 and high for 120. It's our first QC smart attic fan so we are keeping an eye on the activity for these settings and find they are rather good since the low speed keeps morning temps under control economically while the medium speed holds the summer temps to a max of 109 so far this year. The temps haven't needed high speed based on these settings so thats a good thing...most of the heat is getting controlled with medium speed. Our goal is to keep the attic heat as low as possible to keep the air conditioning from having to deal with higher attic temps. We're calculating a savings of about 350 kWh less power for the July/August month compared to last year without an attic fan which quit on us in May 2022, a $120 generic gable fan. So, this is our 4th attic fan and likely the last one since three previous 1 speed attic fans only gave about 8 to 10 years of service if that. Just having a gentle breeze in the attic is all you really need to maintain fair temps vs. a lot of air movement that really doesn't improve temps that much more. We truly believe in getting the temps controlled sooner or earlier than allowing them to raise up high and then ask for maximum performance from the fan when peak heat is present. We are within about 6 degrees above maximum outdoor temps so far this summer so when its 103 outside at 4 PM our attic has been around 107 to 109. Best of all, we are saving money on power, this fan has already paid for itself in just 4 months because of our very expensive electric rates with Southern California Edison which is 42 cents per kWh and increasing more than likely. It's truly a rip off and a monopoly that needs to have a cap on rates and one rate no matter what time of day or year.
We do it by temperature readings instead of scheduled times. You want your attic fan running 24/7 if you need too because it’s extremely hot. Our attic fan are worlds most energy efficient fans. On low speed they run as low as 22 watts.
Shouldn’t the humidity control work so that if the humidity goes above a certain level, then the fan would turn on? If the fan detects that the humidity is falling below that threshold, then the fan should turn off. It seems like the settings are configured to the reverse of that logic.
Turn Fan On: This is the humidity percentage that will cause the fan to turn on, regardless if the temperature settings are not met. For example, the factory setting is set at 70%, meaning the fan will turn on if the humidity in the attic is higher than 70%, even if the temperature in the attic is below the temperature settings in the app. If you do not want this feature, you can select OFF at the top of the list • Turn Fan Off: This is the humidity percentage that will cause the fan to turn off. For example, the factory setting is set at 90%, meaning the fan will turn off if the humidity in the attic is 90% or higher. Tap this setting if you would like to adjust the percentage. If you do not want this feature, you can select OFF at the top of the list.

So did the fan help cool your attic down? Was your ac able to keep your house cooler
As mentioned above, yes. We have noticed the a/c runs less during the evening time since the fan is removing most of the days heat.
It’s makes a huge difference!!
@@qcmanufacturing Yes...likely 20 to 30 degrees cooler in the attic.
Is there a setting for turning the fan on/off at set times ? And days of week ?
That would be very useful.

I am the first one to comment on the video. QuietCool #1!
Can these devices be integrated with Samsung Smart Things? That would be awesome.
Hello,
These units cannot pair with any smart home kits.

Yes, that’s exactly how it works. The fan will turn off if it is above your humidity preset.
@@qcmanufacturing doesn’t the fan running work to lower the humidity? If the humidity is below a certain set point, no need to run.

Great product... just wish it was WiFi where you can monitor from anywhere rather than Bluetooth
Yeah, it’s in the works and will have it in the future but fully automated.
