This jumper is used to bypass the pressure switch on the 2002-forward IQ 2020 spa control system. The PDR Titanium Replacement Heater has its own automatic cut-off in the event of a low flow condition thus negating the need for a pressure switch. After installing the PDR heater simply plug this bypass jumper into the port on the IQ 2020 Control Box that’s marked “Pressure Switch”. That’s it!
