Timed pump rotation
In Auto mode, the controller runs the pumps in cyclic duty/standby operation. The catalogue specifies a default one-hour ON-time before changing to the next pump. Confirm the required duty interval and installation settings when ordering.
Dry-run fault and standby changeover
If the running pump fails to deliver water due to a dry-run condition, the controller switches that pump OFF and provides a fault indication and buzzer alarm. The next pump starts after a one-minute changeover delay, as described in the catalogue.
Pump selection and indicators
The selector provides Auto / Pump 1 / Pump 2 / Pump 3 positions. The controller includes overhead-tank level, water-flow, voltage, power and auto/manual indications. Confirm the source arrangement and connected starter panels.
