MasterTemp/Max-E-Therm Six-Button Keypad

The 461106 is a six-button membrane keypad for Pentair MasterTemp, ETi 250, and Sta-Rite Max-E-Therm pool heaters. It plugs into the existing control board as a direct connector-level swap.

Key Features

• 6-button layout
• Membrane-only, connector-level swap
• No DIP-switch or rotary reconfiguration needed

Compatibility

• Pentair MasterTemp heaters made after 5/6/2021
• Pentair ETi 250 heaters
• Sta-Rite Max-E-Therm heaters made after 5/6/2021
• Does not fit MasterTemp or Max-E-Therm heaters made before 5/6/2021, which use the older 472610Z pad

The heater's rating plate shows its manufacture date, which determines whether this keypad or the older 472610Z pad is the right fit.

This keypad only works on MasterTemp and Max-E-Therm heaters built after 5/6/2021; earlier units use the 472610Z membrane pad and this part will not fit or function on them.
