How do I know what to set the VENTILATION dial to?

Follow the equation below to figure out the necessary ventilation time per hour for your area. 

Does the device have power?

Turn the VENTILATION dial to 60 minutes. The fan will come on within 20 seconds if the device is powered. If you have the rocker version, tap the top of the rocker to turn on both the light and the fan. If you have the toggle version, you must hear the fan turn on to verify the microprosessor is running.  


Is the device working properly?

Follow the instructions in our SmartExhaust™ Testing Guide to determine whether or not your device is installed and working properly.

The SmartExhaust™ will not operate properly if it is not wired correctly.
