Upgrade overview

The 2026 Upgraded 42002-0007S LCD Controller Kit is designed to replace older boards in Pentair MasterTemp and Sta-Rite Max-E-Therm heaters. The full LCD display replaces the prior LED readout, delivering clearer night-time visibility and more intuitive status messages.

Broad compatibility ensures this kit can adapt to many NA and LP series pool and spa heaters, including MasterTemp 200, 250, 300, 400 and 400HD, and Sta-Rite SR200NA, SR333NA, SE400NA, SR200HD, SR333HD, SR400HD, and related NA/LP models. It supports natural gas and LP propane setups, offering flexibility for different installations.

Why this kit stands out

  • Real upgraded design with a full LCD readout for clearer, more informative messages both day and night.
  • Broad compatibility with NA and LP heater electrical systems across MasterTemp and Sta-Rite models.
  • High-performance components including solid-state capacitors, upgraded power chips, and an improved optocoupler module for safer, more reliable operation.
  • Regulated power module and protections against overheating, overvoltage, and short circuits to help maintain stable control.

Easy to install and maintain

  • Easy disassembly and installation: power down the heater, remove the old board, and seat the new board and switch membrane as described in the included notes.
  • Designed for quicker swaps, minimizing downtime and helping you resume heating with minimal hassle.

Note: This kit is intended for compatible models; always verify your heater model and fuel type before ordering. If unsure, consult a qualified technician to avoid wiring mistakes or damage.
