Enervex Variable Speed Chimney Fan Control - 5 Amps

Hi Chance, The behavior you're describing, where the fan doesn't restart until it cools down, is consistent with a built-in thermal switch or heat sensor designed for fan protection. Many fans, especially those used with heating appliances, have these safety mechanisms to prevent operation when overheated and to ensure efficient performance. These thermal switches allow the fan to restart only after it has cooled to a safe operating temperature. Since the Enervex Variable Speed Chimney Fan Control primarily adjusts the line voltage to the fan motor, any thermal protection is most likely integrated into the Enervex chimney fan itself. We highly recommend consulting the installation or owner's manual for your specific Enervex chimney fan to confirm the presence and operational parameters of any thermal sensors or relays. Please ensure your fan model is compatible with the Enervex Variable Speed Chimney Fan Control, as it is designed specifically for Enervex chimney and damper fans (RS, RSV, GSV, and RSHT models).
