Time Delay - DAYLIFF SUNFLO-S 150 Installation & Operating Manual

Controls
Speed Control – Modulates the pump speed by regulating pump efficiency. Turn fully
clockwise for 100% efficiency and fully anti-clockwise for minimum 30% efficiency. This
function allows PV module output to be shared between the pump and battery charging
according to the set proportion and for reduced pump output in the event of over-
pumping. For full output pump operation it should be set to 100% efficiency.
Speed Time Delay – Controls the delay on the low level cut-out re-start with up to
30mins delay being available. The WELL indicator will blink when the delay is activated. If
no delay is required the control should be set to '0', the recommended setting unless the
well has very poor output.
Solar/Battery Mode Selector Switch – A three position switch that selects solar
operation, system isolation or battery operation.
When operating in 'Solar' mode all power from the PV modules will be used for the pump
operation and the battery will be isolated. For non-battery systems the switch should
always be in this position
When operating in 'Battery' mode the system will be powered by hybrid battery/PV module
output according to power available and the battery is charged by surplus PV module
output controlled by the Speed Control. Also when there is insufficient irradiation the
charged battery will power the pump.
