Ok you guys, some of you aren't reading the instructions: MAKE SURE WHEN SETTING A TIME TO COME ON THAT'S EARLIER THAN THE EXISITING TIME, THE TIMER WILL COME ON YOUR SET TIME ON THE NEXT SCHEDULED DAY.
FAQ: For instance, if you are setting the clock and it's 11:00 am, and you set the timer to come on at 7 am, it's not going to come on until the next scheduled day, as it is already past 7 am when you are setting the timer.
FAQ: Yes you can set the timer to come on for 15 seconds every 5 minutes, everyday. What you need to do is set the on time say at 9:00 PM, Off time at 8:59 PM. You can't set it from the same start and stop time (example: 12 PM to 12 PM), it has to have that 1 minute difference.
