This Replacement for the Pentair® Sta-Rite® Thermal Regulator Kit by Optimum Pool Technologies is a part used when replacing your Sta-Rite Heater Manifold on your Max-E-Therm® or MasterTemp® Pool Heater. This item is not included in the Complete Manifold Conversion Kit, but is used along with the SR/SRC200, SR/SRC333 & SR/SRC400 Manifold Conversion Kits. The Thermal Regulator Kit (or Flow Control Thermostat) comes complete with 6” Spring Clip & Cap.

Located between the inlet and outlet water connections on the heater manifold, any signs of wear, damage or rust will indicate it is time to replace the Thermal Regulator. The Thermal Regulator is designed to trigger at 130°F, so if you place the Thermal Regulator in a body of water heated to 130°F and it does not open, this is also a sign that the Thermal Regulator needs to be replaced.
