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. (*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.
Any manual fan operation and DELAY operation will be subtracted from the pre-set VENTILATION time for that hour. If manual fan operation and DELAY operation exceed pre-set VENTILATION time, the excess time will be subtracted from the next hour’s total VENTILATION time.
Bulb Compatibility
Our SmartExhaust™ Rocker style switches (Part no. SED-S) are compatible with most but not all LED bulbs. There are a wide variety of bulb types and bulb qualities now available - we recommend using a DIMMABLE LED bulb to avoid light flickering issues.
We are not made aware of product changes made by bulb manufacturers so we recommend referring to the bulb manufacturer for current specifications. Most bulb manufacturers have compatibility information available so that you can confirm proper functionality between the bulb and switch type.
