4 MAIN WALL CONTROLS
Ventilation Wall Control (99-BC04)
Operating Instructions:
(1) ON/OFF Button
(2) 20/40 Button
(3) Fan Button
(4) Fan Speed Indicator
(5) 20/40 Mode Indicator
(6) 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.)
