The Gecko Temperature Regulation Sensor (9920-400125) is designed to precisely regulate spa water temperature by providing continuous feedback to the control system. This sensor plays a key role in maintaining accurate temperature control and efficient heater operation in compatible Gecko-equipped hot tubs.
Supplied as a direct replacement, this sensor should only be installed once correct compatibility has been confirmed.
