Carrying the CAT-02-PG-AMP designation and replacing legacy part number 80115, this trapezoid-shaped module fits neatly into the angled cutouts of the Tailgater PB340TGW1, Lexington 500 (PB500LXW1), Classic PB700FBW2, Austin XL PB1000XLW1, and Matte Black PB440FB1. The manufacturer explicitly notes that this module is not compatible with the Onyx Edition line.

Under the hood, this unit stands out by offering four built-in OEM temperature programs specifically calibrated for the volumetric airflow and combustion characteristics of Copper Series smokers, alongside one universal program. The digital thermostat offers nine cooking temperature selections from 200°F to 500°F, while the P-setting button provides eight timed pellet feeding options during smoke cycles. A dedicated Prime button enables manual auger feeding to speed up initial startup or clear recovery after opening the heavy steel lid. Wiring is streamlined through heavy-duty Molex 2-pin connectors for the power line, auger motor, draft fan, and igniter, while the RTD internal barrel sensor connects via a JST SM-2P terminal alongside a standard 3.5mm jack for a meat probe.

This controller is the premier pick for owners of Copper Series grills who want specialized factory-tailored airflow programming and short-circuit burn-out protection. If your grill uses a flat rectangular chassis cutout rather than an angled trapezoid, you will need one of the AC03P9 units instead.

While most standard controllers step between 25°F or 50°F increments, this smart controller allows micro-adjustments in single 1°F increments across a broad thermal range from 180°F up to 600°F. The panel features a digital screen with a 4.7-second response time, supported by plug-and-play internal harness plugs. Like other high-performance PID systems, it utilizes auger and blower pulse cycling to maintain equilibrium, which produces a gentle, periodic puffing sound during normal operation.

This controller is the definitive pick for busy parents and multi-tasking pitmasters who want the freedom of remote phone alerts during all-day smoking sessions. If you prefer simple manual dial operation without relying on home wireless networks, the simpler knob or button boards above remain the better path.
