Digital PID Control Board (Updated Firmware)
Early iterations of the 1150 controller utilize a PID algorithm that fails to properly calibrate the auger duty cycle for the 225-250 degree range, leading to massive undershoot. The updated control board features revised logic to manage the pellet feed rate more aggressively when the RTD detects a cooling trend. This is the primary manufacturer-recommended fix for the '225 bug'.

Internal RTD Temperature Probe
The Resistance Temperature Detector (RTD) provides the critical feedback signal for the PID loop. If the sensor's ceramic coating is compromised or significantly fouled by creosote, its thermal conductivity changes, leading to delayed response times and oscillation in the heat curve. Replacing the probe ensures the controller receives an accurate, real-time voltage signal regarding chamber enthalpy.

Internal Flame Broiler Heat Deflector
This mechanical component corrects a convection bypass error where hot air escapes the firepot area and flows directly onto the sensor. By sealing the air gap between the flame broiler plate and the left-side support ledge, it prevents 'false hot' readings that cause the controller to prematurely starve the fire of fuel. This modification stabilizes the ambient air mass rather than just the sensor temperature.
