Mode of Operation:     This timer is programmed using the front panel push switches to set the time. 

Interval mode: The timer starts from the set value and times down with the relay energised. At zero the timer stops and the relay goes off. Operating the reset input re-loads the time to await another start. The timer can be stopped at any time with the stop input, de-energising the relay. The timer can be re-started or reset from stop mode.

Delay  Mode:  The timer starts from the set value and times down with the relay de-energised. At zero the timer stops and the relay energises. Operating the reset de-energises the relay and reloads the time value. The timer can be stopped at any time, the relay remaining de-energised.
