Re: Good Afternoon from Central California

Re: NT150/360 Problem

Thanks for calling that Jerry, what would you do when wanting to slow down the pump then - wait it out? There's no real speed feedback on the controller, but the manual says it's able to start the pump even if it's still rotating, maybe I don't need to slow the pump down. John, will be waiting to he...
