installed underneath a roof</figcaption></figure> <p>An <b>attic fan</b>, is a fan that controls the heat level of a building's <a href="/wiki/Attic" title="Attic">attic</a> by removing the hot air. A <a href="/wiki/Thermostat" title="Thermostat">thermostat</a> is used to turn the fan off and on based on the heat level, while sometimes a manual switch is used. An attic fan can be <a href="/w/index.php?title=Gable&action=edit&redlink=1" class="new" title="Gable (not yet started)">gable</a> mounted or <a href="/wiki/Roof" title="Roof">roof</a> mounted. Extra vents are required to draw in fresh air as the hot air is exhausted. Attic fans are typically used in warmer months when temperatures in an <a href="/wiki/Attic" title="Attic">attic</a> can get above 120 °F (49 °C). A fan may be installed in an attic for the purpose of cooling a whole house by venting hot air out via the attic. These fans are often called <a href="/w/index.php?title=Whole-house_fan&action=edit&redlink=1" class="new" title="Whole-house fan (not yet started)">whole-house fans</a>. </p> <figure class="mw-default-size mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:Roof_Turbine_Ventilator.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/0/0c/Roof_Turbine_Ventilator.jpg/220px-Roof_Turbine_Ventilator.jpg" decoding="async" width="220" height="147" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/0/0c/Roof_Turbine_Ventilator.jpg/330px-Roof_Turbine_Ventilator.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/0/0c/Roof_Turbine_Ventilator.jpg/440px-Roof_Turbine_Ventilator.jpg 2x" data-file-width="6000" data-file-height="4000" /></a><figcaption> Wind-powered roof turbine fan</figcaption></figure> <p>Mechanical attic ventilation fans may be powered in a variety of different ways.

A trend towards solar-powered attic ventilators is observable in the interest of conserving electricity<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> and lowering monthly utility bills. Wind-powered roof turbines, often referred to as "whirly-birds", are also used to ventilate attics and other confined spaces. </p> <div class="mw-heading mw-heading2"><h2 id="Wiring_methods">Wiring methods</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Attic_fan&veaction=edit&section=1" title="Change section: Wiring methods" class="mw-editsection-visualeditor"><span>change</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Attic_fan&action=edit&section=1" title="Edit section's source code: Wiring methods"><span>change source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Attic fans may be wired in different ways.
