The box says it works with wi-fi AND bluetooth but apparently that is only for new production. How do I know if it is new production with working bluetooth? Web site says not available in store but I saw it there today. What is new and what is old?
Asked by: KingGarlicI
The first connection should be with wifi. Check and update versions and then you can connect Bluetooth. The connections both wifi and Bluetooth will be bas d on signal strength of your network but I can control mine from downstairs or upstairs. The techs are great if you have questions or help setting up or identifying device.

How much wiring if any is on the motor?

Asked by: danl
There's about 12-14" of armored connecting the motor with the controller box. The controller box has a short (6") pigtail of stranded wire, and a punched-out hole for connecting hardware. There's a green ground screw that's only accessible if you open the controller box. Inside the controller box, there's a screw terminal connector for the hot and return wires; I removed the pigtail and installed 12-gauge solid wire into the screw terminals with no difficulty.

Customer Reviews

1250 CFM Weathered Wood Wi-Fi Power Roof Mount Attic Fan is rated 3.4 out of 5 by 15.
Rated 5 out of 5 by from Very Pleased There have been a lot of mixed reviews on this one but I am very pleased with the result. Both Bluetooth and WiFi options work for this one. Very easy install. Had a professional roofing company put this on my home. Did the wiring myself and mounted the wifi/ thermostat. Noticed an immediate difference. Went from being 115 degrees in my attic to 90 in a matter of 20 min.

The wifi/bluetooth interface work but are lacking key capabilities: change password and the ability to tell if the fan is running.

When it's 40º in my attic the temp readout was saying 65º. GAF tech support was no help saying the temp sensor down't go below 60º but have gone as low as 53º. They don't know their product, very disappointing. It does link to the WIFI and Bluetooth very easily. I only hope the unit will be more accurate when the temp in my attic goes to around 100º.

Rated 4 out of 5 by from OK fan thermostat not acurate Installed wifi fan. Found that when attic temp is 40 degrees wifi on my phone in bluetooth says 65 dgrees. Called GAF and they said that temp indication does’t go below 60 degrees. I’ll have to check again when the temp gets above 60. Hopefully the humidity is accurate.

App for the smartphone is simple and intuitive. One drawback is on the connectivity of the fan. It's a bit misleading when it states Wi-Fi connectivity. I thought that was implying that you could just connect the fan to your home network/router, but that is not the case. The fan basically broadcasts a Wi-Fi SSID. You use your phone (or another Wi-Fi capable device) to connect to the SSID that the fan is broadcasting, so your phone has to disconnect from your home network in order to connect to the fan. It's not really a deal-breaker for me; just different than what I was expecting from a Wi-Fi capable device. Because of that, I decided to use Bluetooth to connect to my fan instead. The Bluetooth works well and I can connect to the fan while I'm downstairs in my home. I love being able to connect to the fan while using my phone, to see what the current temperature is, and to control the fan as needed. If not for that, I would have to climb up to the very top of my attic to change the thermostat, ensure operation, etc. The fan is powerful. This thing can really move some air around. It also runs quietly; in fact, I can't hear it over the AC units up in my attic. From a design perspective, I would suggest one improvement. Get rid of the enamel coated paint shell for the cover. Switch to the kind that has the paint/color "baked" onto the shell, like the shell on the 1500 CFM model. In general, I'm very happy with this device. It seems to operate as intended and I love the flexibility in controlling the unit from my phone, even if I have to be at home to do so.
