The SmartExhaust is a bath fan and light switch* that also serves as a ventilation controller and fan delay timer. This product provides whole house exhaust ventilation when combined with Greenheck's TruSPECâ„¢ and MultiSPECâ„¢ single-speed fans. (*Wiring the SmartExhaust to operate a light is optional.)
With other fan and light switches, the time that someone is occupying the bathroom does not always provide sufficient run time for the fan to eliminate bathroom humidity or contaminants. Using the SmartExhaust Ventilation and Delay settings, the fan can be set to run on a timer so that adequate ventilation can be met even after someone exits the bathroom. Using the Ventilation setting, the user is able to set the number of minutes per hour that the bathroom exhaust fan should run to achieve desired/required ventilation. Using the Delay setting, the user is able to set the number of minutes the fan should run after the SmartExhaust switch has been turned off. When the switch is turned off, the fan continues to run for the set delay time.
By combining the fan switch with the light switch, the SmartExhaust also becomes an occupancy sensor.
