Hot Tub Temperature Sensor – Curled Finger Design
This curled finger style temperature sensor serves as a critical component for accurate spa heating control. Originally designed for Jacuzzi J-Series hot tubs, this sensor also fits Sundance systems including 1998 and newer 701, 724 models, 2005 780/850E configurations, and 2006 onward 780/680 control systems. The distinctive curly finger probe design typically connects via a 4-wire configuration. Note: If your spa uses a 16-pin connector, you’ll need the box plug variant instead – please check our alternative temperature probe listings for the correct box-style connector option.
