Press and hold the pushbutton of the device you want to program.2. In about 3 seconds you will hear a short ‘beep’. This indicates that you have turned the device ON,are in the programming mode for the device, and have programmed it to turn OFF in 15 minutes.Release the pushbutton.3. Each subsequent press of the device pushbutton while in the programming mode will add 15 minutesto the Delay Off time. (e.g. pressing the pushbutton 3 additional times would set the delay to 60minutes, 15 min. initially plus 3 x 15 minutes additional delay times).4. The device control will remain in the programming mode for about 4 seconds if the pushbutton is notpressed.5. Once the programming mode for the device has ended the device can be turned OFF normally, ifdesired, by pressing the device pushbutton.6. The programmed device will turn OFF automatically at the end of the Delay Time.7. Each time a programmed device is turned off manually or automatically the programming is clearedand must be reentered, if desired.
