Watkins Control Stat Thermistor 2002-Current PN 39530

 Watkins Control Stat Thermistor 2002-Current PN 39530

This control thermostat thermistor sensor detects the spa waters temperature and relays that information back to the system. It simply screws into the No Fault Heater Housing (hand tight only) and then plugs directly onto the IQ 2020 control box motherboard. It's found on the Hot Spring 2005-2006 Accolade, 2004-current Vista and Envoy, 2002-current Grandee, Jetsetter, Prodigy, Sovereign and Vanguard. Also on the Hot Spring 2003 Highlife, 2002-2003 Landmark and 2002 Sovereign I LE (limited edition) and the 2006-current Aria. This thermistor can also be found on the Tiger River 2002-current Bengal and Sumatran, 2002-2004 Siberian and 2003-current Caspian spa models. Works in conjunction with the Hi-Limit Thermistor PN 39525.

Test Procedure

1. Set the meter to 20K on the OHM scale.
2. Record the temperature of the spa water.
3. Unplug the thermistor from the control box.
4. Meter across the two Thermistor leads.
5. Refer to the Temperature versus Resistance chart below to find the correct resistance value for the temperature measured. If the temperature and resistance does not match that of the chart, this test has failed and the thermistor must be replaced. Remember if the spa has been inactive, the spa water temperature may be different
than the water temperature in the heater housing.
