Hi
I am looking at this unit. What I am confused with is why the tub heater runs with the tube on the top right disconnect. Do pressure switches with dual ports work of differential pressures? When I disconnect the pressure hose off the unit(top right of picture the unit fires. When I attach it the unit does not fire.
