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?

Usually on those you would need to two speed pump. The low speed is used to filter and heat the water and high speed when using the spa. Where is your pump plugged into the circuit board, at J23?
To have the spa heat on demand and not just in a filter cycle it needs to be in the Standard mode. If you have the VS501 then dip switch #2 can be put in the on position and it will remain in standard mode. If you have the VS510 then you should have a mode button you can switch from economy mode to standard using that button.
