I just bought a new Vectra M1 and I calibrated the pump for a max and low setting. Ive been running it at a "constant" green LED setting that is set to the perfect flow for my duel herbie design overflow. Then all of a sudden the Vectra decides to go on a lower setting which in turn is to low for my overflows and floods my sump and turns my overflow alarms on.
Why is this happening and how can I get it to stop.
