I have a brand new Balboa VS510SZ controller heat pack installed. I keep getting error codes indicating low flow through the heater. I have 1 high speed pump. I have a clear 2" piece of plumbing from the spa to the pump to the heater and back into the spa.

There is an extremely high amount of water coming through this plumbing so I know here is good flow.

I need to set the controller so the pump does not shut off until it reaches the set temp because then there is a low flow warning.

Does anyone know how all of my modes and dip switches should be set?
