Pentair Genuine OEM MasterTemp/Max-E-Therm 6-Button Control Board Kit

The Pentair 461105Z is the six button control board kit for MasterTemp and Sta-Rite Max-E-Therm gas heaters. It is the factory part, the same board Pentair fits on the production line.

Fit

MasterTemp and Max-E-Therm heaters share this control system. On the Max-E-Therm side it covers the SR200, SR333 and SR400, where it is listed in the electrical system parts breakdown.

Board or pad

If the heater ignores button presses but the display and firing logic are otherwise normal, check the six button membrane pad first, since it is a separate part. If the display, temperature control or diagnostics are acting up, the board is the more likely cause.
