If the regulation pressure is greater than SP, the FL setting might be too high. Reduce the minimum operating frequency FL (if the electric pump enables this).
What to do if the DAB Inverter display shows BL?
If the DAB Inverter display shows 'BL', the potential causes and solutions are: * No water. Prime the pump and ensure there is no air in the pipelines. Also, check that the intake or any filters are not obstructed, and verify that the pipeline from the pump to the inverter is not damaged or leaking. * Pump not primed. Prime the pump and ensure there is no air in the pipelines. Check that intake or any filters are not obstructed. Verify that the pipeline from the pump to the inverter is not damaged or leaking. * Flow sensor disconnected. Check the connections to the flow sensor. * Entry of setpoint too high for pump. Lower the setpoint or use a pump suited to system requirements. * Inverted direction of rotation. Check the direction of rotation. * Incorrect setting of pump curr...
