Quartz Crystal' generates its own frequency. Which is divided by CMOS frequency dividers generating accurate time base. This signal is given to synchronous counter which drives display. The elapsed time is continuously compared with reset time. At the set time output is generated from driving relay.
The relay can be operated in 'Delayed On', Delayed Off, 'Auto reset' modes as per the application.
