The Pentair 470179 Thermostat Circuit Board is an OEM electronic component designed to maintain the performance of MiniMax and PowerMax heaters. This board is responsible for controlling and regulating temperature, ensuring precise and reliable heater operation. It is compatible with several models, including MiniMax, MiniMax Plus, and PowerMax heaters in the 150, 200, 250, 300, 350, and 400 series. Engineered to Pentair’s OEM standards, this circuit board delivers dependable functionality and is built for long-lasting use in demanding pool and spa environments. Easy to install as a direct replacement for the original, it provides a cost-effective solution for restoring heater performance, preventing downtime, and supporting consistent temperature control.
Note: In January 1996, the circuit boards for Minimax Heaters were changed at the terminals by request of the American National Standard Institute (ANSI) and the American Gas Association (A.G.A.), the two approval agencies for the manufacturing of gas heaters in the United States. If you have a heater manufactured before January 1, 1996 and you receive a newer circuit board with the smaller terminals and the older thermistor has larger connectors, the larger connectors can be crimped so they will fit tight on the newer circuit board terminals, contact a Pool Service Professional for details.
