  • Internal transformer with commercial terminal block, On/Off power switch and LED status indicator
  • Large backlit LCD display

  • 4 programs: A, B, C; program D can operate concurrently
  • 8 start times per program
  • Nonvolatile memory and real time clock/calendar circuit to retain programs as well as correct date and time - with no battery required
