How do I program the ON/OFF times for a day?

Press and hold Prg button for 3 seconds until 'Hold' shows, then release; Mode screen appears where you can select programming type (24 hour or individual days). Set each ON/OFF time with Adv/Ovr or Boost buttons before pressing Prg to confirm and move on. Continue through all programs and exit by pressing Prg once to save.(Page 9-10)
