Jumper, Pressure Switch, IQ2020

This jumper is used to bypass the pressure switch on the 2002-forward IQ 2020 control box. 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!

It simply screws into the No Fault Heater Housing (hand tight only) and then plugs directly onto the motherboard inside the IQ 2020 control box.
