8 Steps on How to Set Attic Fan Thermostat?

Attic fans are a great way to keep your home cool, but only if they’re used correctly. If you have an attic fan or are thinking about getting one, here are a few steps on how to set up an attic fan thermostat to make it as effective as possible.

Step 01: Type of Thermostat

The first step is to determine the type of thermostat you will need. There are two basic types: those that use a temperature sensor and those that use a timer.

Thermostats that use a temperature sensor are more accurate, but they can also be more expensive. If you have an attic fan with a humidistat, then you will need a thermostat that uses a temperature sensor.

Step 02: Type of Attic Fan

The next step is to determine the type of attic fan you have. An electric or solar attic fan can be mounted on either the roof or the gable mount end. The two most common types of these devices are those controlled by switches and those controlled by timers.

For example, Remington solar attic fans have an automatic on/off switch that turns the fan on when the temperature in the attic reaches a certain level and then shuts it off when the attic temperature drops below that level.

Step 03: Find the Right Location

The second step is to find the right spot for your attic fan thermostat. It should be placed in an area that gets a lot of direct sunlight, as this will help make sure it works properly.

You also want to make sure that it’s placed high enough on the wall so that it won’t be covered by a door or curtain. This will ensure that it can detect the temperature in your attic accurately.

Step 04: Set the Temperature

The third step is to set the desired temperature for your attic fan thermostat. You’ll want to set it between 90° and 110°, as this is the range where attic ventilation fans are most effective.

But be sure to keep in mind the attic temperature of your house. In the case of quite hot air, it may be advisable to lower the thermostat.

Step 05: Connect the Thermostat

The fourth step is to connect the thermostat to your attic fan. This will vary depending on the type of thermostat you have, so be sure to follow the instructions that come with it.

Most thermostats will have a wire that goes to the fan and a wire that goes to the power supply. The thermostat will also have a ground wire that needs to be connected to a metal screw or pipe.

Step 06: Test the Thermostat

The fifth and final step is to test your attic ventilation fan thermostat to make sure it’s working properly. To do this, simply wait for the attic temperature to rise above the set point.

If the thermostat is working properly, the fan should turn on automatically. If not, check the connections and make sure that the power is turned on.

Step 07: Set the Humidity

If you have an attic fan with a humidistat, you’ll also need to set the desired humidity level. The ideal range is between 50% and 60%.

Anything lower than 50% can cause the wood in your home to dry out and become susceptible to damage. A humidity level greater than 60% can be conducive to mold and mildew growth.

Step 08: Adjust Temperature as Necessary

If you find that the attic fan thermostat isn’t keeping your home cool enough, you can adjust the temperature setting. If you find that the fan is turning on too often or not often enough, you can adjust the humidity level.

By following these steps, you can make sure that your attic fan thermostat is set up for maximum efficiency. Now that you know how to set up an attic floor fan thermostat for your needs like a house fan, soffit vents, etc.

Things to Consider When Buying Attic Fan Thermostats

There are a few things you need to consider when buying an attic fan thermostat. These include:

Timer or Temperature Sensor

As we mentioned before, there are two types of attic fan thermostats: those that use a timer and those that use a temperature sensor.

Thermostats that use a timer are less expensive but less accurate. Those that use a temperature sensor are more accurate but can be more expensive.

Temperature Range

You want to make sure that the thermostat has a wide temperature range so that it can be used in different attics. It can range from 90° to 110°, so be sure to check the specs before you buy. If you have a ridge vent system, you’ll want a thermostat with a lower temperature range so that it doesn’t turn on too often.

Maximum Current

The maximum current is the amount of electricity that can flow through the thermostat. This is important because you don’t want to overload the system and cause a fire.

Be sure to check the maximum current rating of the thermostat before you buy it and make sure it’s compatible with your attic fan.

Humidistat

If you have an attic fan with a humidistat, you’ll need a thermostat that uses a temperature sensor. This is because the humidity level in your attic can affect the temperature reading.

Whenever the humidity level rises, the temperature sensor will compensate for it and give you an accurate reading.

Accuracy

You also want to make sure that the thermostat is accurate, as this will ensure that the fan turns on and off when it should. And remember, attic fans can be noisy, so you want to make sure that it’s turned off when it’s not needed.

Ease of Installation

The last thing you want to consider is how easy the thermostat is to install. You don’t want to have to hire an electrician just for the fan installation, so look for one that’s easy to install. Most thermostats will come with instructions, so be sure to read them before you buy.

These are key considerations when buying an attic fan thermostat. By taking these into account, you can be sure to find the right one for your needs.
