    COR 20 lowest setting?

    Dialed the COR20 that’s running my manifold down to 15%, thought this would be better than closing off the valve to the UV to restrict flow. Got to 20% and it read something like 7W, went to 15% and it now reads 120W, is this an error because I have it turned down that low? Or at this low level is the pump having to now work harder somehow?

    Is the pump stalling at 15%? If so that would explain the wattage jump.

    I’ve turned it back up to 20 and it’s now reading 5W again.
