The SmartExhaust™ Bath Fan/Light Switch is a simple and efficient solution for achieving adequate bathroom ventilation and meeting exhaust ventilation requirements. The SmartExhaust™ is designed to replace the bathroom fan and light switches with one smart controller and features programmable settings for running the exhaust fan as much or as little as you want, automatically.


FEATURES & BENEFITS

  • Earn LEED and ENERGY STAR points for enhanced exhaust ventilation*
  • Make standard bath fans ASHRAE 62.2 compliant*
  • Smart microprocessor provides precise, user-controlled ventilation
  • Works with most incandescent, CFL, fluorescent and LED lights
  • Optional light and fan time out after 60 minutes (Rocker only)
  • Available in toggle and rocker models in a variety of colors
*When used with ASHRAE 62.2 compliant fans

PRODUCT DETAILS


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.

 

Example of Operation

The user wants to VENTILATE the bathroom for 20 minutes every hour with a 10 minute DELAY

Figure 1

  • The VENTILATION dial is set to 20 min/hr. 
  • The SmartExhaust™’s microprocessor performs the following equation to determine when to run the fan to meet the VENTILATION setting, based on 1 hour (60 mins).
    60 MINS - VENTILATION SETTING = START VENT TIME
    60 MINS - 20 MINS = 40 MINS
  • The SmartExhaust™ will turn on 40 minutes into the hour and run for 20 minutes. (Figure 1A)

Figure 2

  • The DELAY dial is set to 10 min/hour
  • Someone uses the bathroom for 5 minutes and manually turns the SmartExhaust™ on. The microprocessor logs this 5 minutes of use. (Figure 2A) 
  • The occupant exits the bathroom, turning the switch off, and the SmartExhaust™ continues to run the fan for the 10 minutes of DELAY run time. (Figure 2B)
    5 MINS OF MANUAL USE + 10 MINS OF DELAY TIME
    = 15 MINUTES OF VENTILATION
  • 15 minutes will be subtracted from the total required 20 minutes of VENTILATION time. 55 minutes into the hour, the fan will turn on and run for the 5 additional minutes needed to complete the required ventilation. (Figure 2C)

OPERATING INSTRUCTIONS

  • Move switch up to turn on the fan and light
  • Move switch down to turn off the light. The fan will continue to run for a pre-set DELAY time (unless manually canceled)
  • To cancel DELAY time for the toggle version, turn the switch off and back on again within three seconds. Within another three seconds, turn the switch off and the fan will shut off canceling the DELAY for that use. For the rocker version, simply turn the switch off again after use.
  • DELAY will not activate until the light/fan has been on for at least 10 seconds
  • The fan will automatically come on once per hour for the pre-set VENTILATION time.

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.
