The high-limit thermistor sensor is a safety device designed to communicate with the system to shut down the heater if the water temperature exiting your heater exceeds 118 degrees F. It simply screws into the No Fault Heater Housing (hand tight only) and then plugs directly onto the IQ 2020 control box motherboard. Found on the Hot Spring 2005-2006 Accolade, 2004-current Vista and Envoy, 2002-current Grandee, Jetsetter, Prodigy, Sovereign and Vanguard.
