e) Water Saver Timer (S1 dip switch 7 & 8)
The water saver timer allows the water valve to close and the pump motor to circulate
water in the tank during the final part of harvest. The water valve is open during harvest
for a maximum of 6 minutes or the length of harvest minus 0, 10, 30, or 50 seconds
(determined by the water saver timer setting), whichever is shorter. When the water
valve closes, the pump motor energizes and runs for the time determined by the water
saver timer setting.
The water saver timer is factory-adjusted, and no adjustment is required.
