NEW!!!   SmartExhaust(tm)

Bath Fan/Light Switch/Delay Timer/Ventilation Controller

 

When a person enters the bathroom and turns on the light, the fan is also energized. After the person leaves the bathroom and turns the light out, the fan continues to run for the set Delay time.

In addition once an hour the fan is energized for the set Ventilation time.

Now the smart part is that the microprocessor monitors manual operation time and Delay time and subtracts it from the set hourly Ventilation time.

For example, with a 20 minute Ventilation setting and a 10 minute Delay setting, a person enters the bathroom and uses it for 5 minutes. The fan will continue to run for another 10 minute Delay time. That totals 15 minutes of run time for that hour. The microprocessor will subtract that 15 minutes of operation from the 20 minute set Ventilation time and at the end of the hour, the fan will only run for 5 additional minutes.

The SmartExhaust™ is very smart! For example your teenage daughter uses the bathroom for 20 minutes. When she leaves the fan will continue to run for 10 minutes. That’s 30 minutes. 10 minutes more than you needed for total ventilation time. The SmartExhaust will now subtract that extra 10 minutes from the next hours Ventilation time, only running for 10 minutes in the next hour.

The SmartExhaust™ is so smart, you can tell it you don’t need the fan to run its Delay time when you leave the bathroom. A user cancelable delay. When you turn off the light, turn it back on then back off again within a few seconds to tell the SmartExhaust™ you don’t want the fan to continue running its Delay time. Sometimes you don’t need or want the fan to run when you leave the bathroom.

Since you are substituting an existing switch, or maybe even two, there are no additional labor costs to the SmartExhaust™ installation. With the light and fan being the same switch, the ventilation strategy can’t be defeated.

It’s simple, it’s smart, it’s easy, it's economical.

   

The SmartExhaust™ is designed as a replacement for the bathroom fan and light switch. By using a microprocessor to monitor and control fan operation, a precise amount of ventilation can be provided.

There are only two settings on the SmartExhaust™ switch, Ventilation and Delay. Ventilation is the minutes per hour that you want the fan to operate. Delay is the number of minutes you want the fan to run after the bathroom light has been turned off. The Delay time provides additional run time of the fan to complete ventilating the bathroom after use.
