Overview

The Pentair MasterTemp Max-E-Therm 6-Button Membrane Pad Kit (Part 461106) is a genuine Pentair replacement keypad membrane designed to restore control-panel operation on compatible Pentair MasterTemp and Sta-Rite Max-E-Therm pool and spa heaters. This membrane pad serves as the user interface for heater operation, empowering you to adjust temperature settings, switch operating modes, and interact with the heater’s digital control system.
