from my reading it is meant to run from 08h00 to 16h30 so that the pump has stopped rnning seems about right.

what i would like to know is how do i read the clock bit (grey hand and arrow)? as well as the 4 boxes with numbers in them.

so soon after 14h00 it had stopped. so i may guess that it stopped 13h30. meaning it is possibly off by some 3 hours
