You have wired your timer correctly and the lights turn on when you push on-off button.
If lights do not turn on, we need to review the wiring.
Your timer looks like photo below.
I'm going to parrot back the manual with some extra words.
To start, press the reset button and clear any programmingPrograming overview:
Each program has ON time ... and OFF time
So you set program1 ON and then set program1 OFF
When you set program1 ON, you choose the Day, hour and minute you want program1 to turn ON.
And then you set program1 OFF, and choose Day, hour and minute for program1 to turn OFF.
Your ON-OFF times for program1 should be on same days.
For example program1 ON for all-days-of-the-week, but program1 OFF is for TU Tuesday, then timer will not work.
IN this case, program1 OFF should also be set for all-days-of-the-week.
Let's start.Setting the clock
Press and hold CLOCK button
Keep holding CLOCK button and press DAY button until display shows current day (MO TU WE TH FR SA SU)
