Tbgrepts Digital PID Wi‑Fi Control Board for Pit Boss Pro Series II 850 (PB850PS2) — Dual Probe, Tight Temp ±5°F

Tbgrepts Digital PID WiFi control board is a direct replacement for the Pit Boss Pro Series II 850 (PB850PS2) that restores precise temperature control, Wi‑Fi monitoring, and dual probe support.

If your Pit Boss Pro Series II 850 is showing temperature drift, erratic auger behavior, or lost connectivity, this Tbgrepts replacement board (compatible with part number 80146) swaps in to bring back consistent, programmable heat control. The unit uses a PID algorithm to constantly adjust the auger and fan for tighter temperature hold, supports two meat probes, and offers smartphone control for monitoring and adjustments from a distance.

How does the PID controller improve cooking consistency?

The PID (Proportional-Integral-Derivative) controller continually compares actual grill temperature to your setpoint and subtly changes auger and fan activity to reduce swings. That means fewer hot or cold spikes while smoking or grilling, resulting in more predictable cook times and texture outcomes.

• PID algorithm maintains tighter temperature +/- 5°F under normal conditions
• Automatic auger and fan adjustments reduce overshoot and undershoot
• Temperature range from 180–500°F for smoking, roasting, and searing
• Improved fuel efficiency through optimized pellet feed

What connectivity and probe features does this board offer?

The replacement board adds Wi‑Fi monitoring and two meat‑probe inputs so you can track grill and meat temps remotely and set target probe alarms. The MPC button activates the programmable meat probe port for straightforward internal-temperature control during long cooks.

• Wi‑Fi access for smartphone monitoring and adjustments
• Two probe ports for probe and backup probe monitoring
• MPC button and controller knob for quick probe setpoint control
• Real‑time temperature readouts and alerts via compatible app

Will this replacement save pellets and improve efficiency?

Yes — by using PID logic to match pellet feed and airflow to actual demand, the controller minimizes unnecessary pellet consumption. The result is steadier heat with fewer pellets burned to compensate for temperature swings.

• Optimized auger cycling reduces wasted pellets
• Controlled fan speeds reduce overventing and heat loss
• More consistent cooking temperature extends pellet life per cook

How easy is installation and compatibility with my grill?

This board is built to be a drop‑in replacement for the Pit Boss Pro Series II 850 and replaces part number 80146; basic DIY skills and common tools are usually sufficient for installation. Always power down, disconnect the grill, and follow safety precautions or consult a certified technician if you're unsure.

• Designed for PB850PS2 Pit Boss Pro Series II 850 models
• Direct replacement for Part 80146 with matching connectors
• Requires power disconnect and safe handling during swap
• Most users complete install within an hour with basic tools

Who is this for? Grill owners who want to restore or upgrade temperature control on a Pit Boss Pro Series II 850 — including backyard pitmasters, weekend smokers, and anyone seeking better fuel efficiency and remote monitoring. If your grill struggles to hold set temperatures, exhibits erratic auger/fan cycles, or you want to add reliable probe and Wi‑Fi features, this Tbgrepts PID control board is a practical replacement part to bring your PB850PS2 back to consistent performance.
