Thermistor, Control Thermostat, Hot Spring, Tiger River, Limelight

Sku: 39530

OBSOLETE-Use 39205.

This control thermostat thermistor sensor detects the spa water’s 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 motherboard inside the IQ 2020 control box. (If your existing thermistor plugs into the side of the spa’s control box see item 38415). Always replace thermistors in pairs (ie; 39205 & 39204).
