Setting up your Simple Ventilation Timer Switch

Before you begin...

The Simple Ventilation Timer Switch is only designed for use in single-pole circuits, i.e. lights that are only controlled by one switch.

The Simple Timer Switch is easily installed the same way as all our other switches!

First time use

When the Simple Ventilation Timer Switch is plugged in for the first time, all three LEDs will light up. 

To turn timer on:

  • Press the on toggle or desired time button to turn the load on.
  • The first time use default is 30 minutes.
  • If you press the toggle, it will count down from the last time used.
  • Corresponding indicator light will light up for the duration of the time selected.

To turn the load off:

  • Press the off toggle to turn the load off or wait for the selected timer to run out.

To select different timer:

  • Press the button corresponding to the desired time.
  • Corresponding indicator light will light up for the duration of the time selected.

 

Ventilation Timer

The Ventilation Timer runs for the selected amount of time every hour to help ensure adequate indoor air ventilation.

  • Setting the dial to "0" means the Ventilation Timer will never turn on
  • Setting the dial to "60" means the bathroom fane will run continuously 

How the Countdown Timer and Ventilation Timer work together

The Ventilation Timer switch takes into account both independent timers. If for example the ventilation dial is set to 20 minutes/hour, the timer will subtract 20 minutes from 60 minutes and determines its timer needs to come on 40 minutes into the hour and run for the remaining 20 minutes of that hour. 

Example 1:

If the countdown timer 10-minute button is pressed when someone uses the bathroom and the timer runs the full 10 minutes, the timer switch will track the 10 minutes of ventilation. The Ventilation Timer switch will subtract the 10 minutes from the required 20 minutes of total ventilation time. 50 minutes into the hour the fan will turn on for 10 additional minutes. Resulting in 20 minutes of total run time that hour.

Example 2:

If the countdown timer 30-minute button is pressed when someone uses the bathroom and the timer runs the full 30 minutes, the timer switch will track the 30 minutes of bathroom use and not turn on the Ventilation Timer for that hour as 30 minutes exceeds the 20 minutes of required ventilation.
