About This Item
The Pentair Thermal Regulator Kit (77707-0010) is the OEM replacement thermal regulator assembly for Pentair MasterTemp and Pentair (formerly Sta-Rite) Max-E-Therm pool and spa heaters.
⚠️ IMPORTANT: HEATER COMPONENT — LICENSED TECHNICIAN REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.
The thermal regulator monitors and responds to water temperature within the heater's heat exchanger circuit. When this component fails, the heater may short-cycle, fail to reach set temperature, or shut down on high-limit fault — replacing it with the correct OEM kit restores accurate thermal sensing and proper heater operation. Confirm part number 77707-0010 against your existing component or your heater's service manual before ordering.

Pro Tip
Locate the part number on your existing thermal regulator or in your heater's parts diagram before ordering — both the MasterTemp and Max-E-Therm lines have been produced in multiple revisions, and confirming 77707-0010 against your unit's service manual ensures you receive the correct replacement. Have your heater's model and serial number on hand when consulting your technician or the Pentair parts documentation.
