Questions & Answers

How do I get the timer back to program after manually turning off the lights? I have tried to reset it repeatedly but the timer still shows manual instead of prog.  Thanks

Asked by: Tom Piacun
There is nothing that needs to be done. The switch will automatically return to the program mode at the next scheduled trigger.
