ON/OFF Indicator 

 

Turning on the Control: 

Press the ON/OFF Button    . The ON/OFF indicator light will 

illuminate. 

 

Setting the Ventilation Speed: 

Press the Fan button     to select LOW or HIGH fan speed. The 

corresponding indicator light will illuminate. If both LO and HI 

indicator lights are off, the fan is OFF, but will turn ON if required 

by a remote timer (if installed). 

 

Setting the 20/40 Mode:

 

After a fan speed has been selected, press the 20/40 button. The 20/40 mode indicator light will illuminate. 

The 20/40 mode is a repeating cycle. The fan will run at LOW or HIGH speed for 20 minutes, then turn 

OFF for 40 minutes. Some units are equipped to recirculate the air in your home during the 40-minute 

cycle with no ventilation. The control will automatically detect this feature and recirculate the air during the 

40-minute cycle at the selected fan speed.

 

 

 
 
 
 
 

 

 

 

Attention

 

•

 

Only one main control can be installed on your system. 

•

 

Recirculation is not available on all models. 

•

 

Timers will not function when mode of operation is set to “OFF”, unless specifically 

installed for the function. (See Installation Guide for other options.)
