This thermostat has a simple temperature dial so you can adjust it to the desired temperature wherever you want the attic fan to turn on automatically. Then, when the attic temperature drops below that temperature, the fan will turn off. An attic fan can be turned off by raising the temperature setting on your thermostat. This thermostat is located in the attic, near the attic fan, so to do this, you will have to go to the attic.
Some attic fans also come with a humidistat, so in this case, make sure to turn up the humidistat settings as well. If you forget to turn up the humidistat setting, the fan will operate when the humidity level is reached, even if the attic temperature is below the thermostat setting. It is best to raise the temperature and humidity settings to their maximum values to prevent the fan from operating in any case. What is an attic fan? AT.
An attic fan or electric attic fan is a fan specially designed to blow warm air out of the attic space. The fan is normally mounted on top of the roof itself, drawing the warmer air out first while drawing in cool air from strategically placed intake vents. Will an attic fan look weird on the roof? AT. No, the fan housing is only 8″ tall and 22″ in diameter.
Can only be seen from one side of the house, usually the back. How much energy does an attic fan consume? AT. Very little, just like 2 or 3 bulbs, 250 watts. Much, much less energy than an air conditioner uses to cool the effect of warm attic air.
How do you operate an attic fan? AT. An attic fan is usually automatic. An adjustable thermostat, which is included, turns the fan on and off depending on the temperature. If you have a humidistat installed, also turn the fan on and off according to humidity.
Will the attic fan draw air from inside my house? AT. No, air is taken from the outside through the attic vents. The already cooled air inside the house is intact. When does the attic fan work? AT.
We set the adjustable thermostat to turn on the attic fan at 100°F and turn it off at 90°F. If you have a humidistat, the attic fan turns on at 70% humidity. What is a humidistat and why would I need one? AT. In certain areas, an attic can become very humid.
Moisture in the attic can condense and cause attic leaks. With more than 70% humidity, the humidistat turns on the attic fan to vent moisture no matter the season. Where is the best place to locate an attic fan in the attic? AT. The exact location of the fan doesn't matter at all.
The important thing is the location of the entrance grilles. Ventilation grilles should cause as much cross-flow through the attic as possible. What color do attic fans come in? AT. Jet Fan Attic fans come in natural aluminum color.
Feel free to paint the dome to match your home. Will the roof leak after installation? AT. No, the fan has a one-piece heavy metal flash. The flashing fits under the roof tiles and is placed over the tiles below.
Attic frame beams are only 15″ (or any gap) apart, will the attic fan fit? AT. A Jet Fan attic fan is installed in the ceiling and does not go into the attic. The hole cut out for the attic fan is usually between the rafters. How much money can I expect to save? AT.
The exact savings depend on the style of the house. In general, the more roof area directly under the attic a house has, the more you can save. Savings after fan cost will be realized in any home in one or two seasons along with increased comfort. What is a whole-house fan? AT.
Sometimes fans throughout the house are called fans. However, the whole-house fan is a completely different concept. Fans throughout the house draw air through the windows of the house and blow warm air out of the house through the attic. Of course, a whole-house fan would never be used concurrently with an air conditioner.
I have a fan for the whole house, do I need an attic fan? AT. We recommend this, since you do not operate the fan in the whole house during very hot days, when you just need to turn on the air conditioner and keep all the windows closed to prevent the hot summer air from entering. Your attic will still heat up, so venting the extremely hot attic air will need to be vented. Do not use the whole-house fan, as it will blow cold air from your home into the attic.
Also, you should NEVER run the whole-house fan without opening the windows to feed the need for whole-house fan airflow. Turn off the attic fan by pressing the shutdown switch on the control box. The basic principle of an attic fan is that it expels warm air from the attic space. An attic fan draws air into the attic from the outside using the ceiling vents that you should have already installed on the eaves.
As the attic fan draws outside air into the attic, it expels the warm, stale air through attached dormer windows. In this way, the attic fan replaces stuffy air with fresh air, cooling the attic and, in turn, its living space below. If the attic fan also has a humidistat, make sure that the humidity value set in it is always higher than outside. Some attic fan models come with a built-in remote control, and for some, you can optionally purchase a remote control kit (like this one).
Here, the attic fan is connected to the power grid via a smart plug that turns on and off based on commands it receives from smart devices. Mention this in the quote, as the gable mounted attic fan will have a high quality Dayton shutter instead of a dome and is more complex to install. Attic fans can be controlled via thermostat, remote controls, smart devices, or a combination of all of these. Some attic fans are designed with thermostats and turn on automatically when the air reaches a certain temperature.
Make sure your attic has enough ventilation outlets for the highest cubic feet per minute (cfm) fan rating. Turn off the fan when finished, or allow it to turn off only if you have it configured to operate for a certain period of time. If the attic fan is controlled by a smart switch, simply tell your Alexa or Google device to turn it off. The humidistat detects the humidity in the attic and turns on the fan when this humidity level exceeds the humidity value set in it.
Many people don't choose to install a wall switch controller for attic fans and are instead connected directly to the power grid. No matter where you live, you can take advantage of the benefits of an attic fan to help make your home more comfortable. To turn off an attic fan controlled by a thermostat or by a humidistat and thermostat, simply turn the settings up to the maximum. With the remote control, you can control the speed, temperature and humidity settings of the fan, and you can even turn off the fan in your living room.
