As a veteran-grade \u003cstrong\u003eHVAC relay and transformer\u003c\/strong\u003e assembly, the FC24 allows a dedicated \u003cstrong\u003e24 volt thermostat\u003c\/strong\u003e to manage room-to-room air transfer, enabling precise temperature-based activation. This module eliminates the need for manual wall switches by providing a low-voltage interface that fits directly within the AS1 or AS2 electrical junction box. It facilitates multi-mode operation including \"Heat,\" \"Cool,\" and \"Fan\" constant-run settings, provided the appropriate jumpers are installed at the thermostat base. Rigged for professionals requiring a clean, \u003cstrong\u003elow-voltage fan control\u003c\/strong\u003e solution, this unit ensures the transfer fan only operates when there is a call for air movement, optimizing energy efficiency and system performance across divided zones.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Thermostat Integration:\u003c\/strong\u003e Seamlessly bridges \u003cstrong\u003e24 VAC thermostats\u003c\/strong\u003e with line-voltage \u003cstrong\u003eAireShare transfer fans\u003c\/strong\u003e for automated climate control.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact Form Factor:\u003c\/strong\u003e Engineered specifically to fit inside existing \u003cstrong\u003eAS1 and AS2 junction boxes\u003c\/strong\u003e, ensuring a streamlined, professional installation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBuilt-In Relay \u0026amp; Transformer:\u003c\/strong\u003e Consolidates the \u003cstrong\u003e24V transformer and switching relay\u003c\/strong\u003e into a single module, reducing field wiring complexity.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVersatile Control Logic:\u003c\/strong\u003e Supports temperature-rise or temperature-fall activation, allowing for customized heating and cooling distribution.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eIs the FC24 required for all AireShare fans?\u003c\/strong\u003e\u003cbr\u003e\nNo, it is only necessary if you intend to control the \u003cstrong\u003eAS1 or AS2 fans\u003c\/strong\u003e via a low-voltage 24V thermostat rather than the standard line-voltage manual switch.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this unit come with the necessary wiring for 3-speed control?\u003c\/strong\u003e\u003cbr\u003e\nThe FC24 provides the interface for thermostat control; however, 3-speed operation on the AS2 model typically requires specific wiring configurations at the equipment or an additional selector switch.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use this with a smart thermostat?\u003c\/strong\u003e\u003cbr\u003e\nYes, as long as the thermostat provides a standard 24V signal. Note that some digital thermostats may require a jumper between the W, Y, and G terminals to ensure the fan runs in all modes.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
