I wish to change from a manual clock timer to Suraielec Wi-Fi timer for lighting only @120 v..
So which terminal number does the black hot wire fix and which terminal number for the lighting load.
The white neutral would be terminal N? And the jumper from terminal # to terminal # as I want to be sure .
Amy help please
thanks
