Timer switch
This home is equipped with some Timer Switches. To open the light, press the lower part of the button ONCE. The light will stay on for a few hours and automatically shut off. Just before shutting off, the switch will beep several times to announce that the light will be closed. To manually close the light, press the lower part of the button TWICE.
Please, do not forget to lock doors and close all the lights (inside and outside) before leaving back home. Thanks!
