The WTTK is a whole house fan wall control that uses temperature or a timer to control the fan. Temperature control never overcools the home and only runs the fan as long as needed. All wiring is done in the junction box on the fan. Includes 50' plug&play cable to connect wall control to the fan. Includes built-in safety timer feature and option to add a Wireless Remote Control and outdoor temperature sensor.
