This kit contains three different timing modes using only ONE IC (Micro controller) and some support components on a single-sided PCB. This is a lot less than many single-mode traditional timers. The timing modes and delay ranges are selected by on-board push on switches. Simply select the time delay you want and that’s it – no adjustment required. Timer can countdown from 1-99 seconds, 1-99 minutes or 1-99 hours. Timer has 2 digit seven segment led display and  4+1 press buttons, UP, DOWN, MODE, START + RESET. UP, DOWN set time that we want to count down. MODE selects the unit (sec., min. or hours) that we want to count down. Once we set time, set MODE, we can start countdown sequence. After countdown the relay turns on. To restart Timer, we must press RESET button.
