Swimables cross-references SW-41-010 to Pentair 77707-0010, and Pentair lists 77707-0010 as the thermal regulator kit containing the thermal regulator, spring, O-ring, cap, and spring clip. The thermal regulator works with the heater water system to help control flow through the heat exchanger and maintain the intended outlet temperature. Pentair lists this replacement for MasterTemp and Max-E-Therm 175, 200, 250, 300, 333, and 400 heater families and specifically excludes the 125,000 BTU heater.
