Quick Start-up Guide

To begin using the Pellet Pro® Patriot right away, consult this “Quick Start-up Guide” and review

section five in the Pellet Pro® Patriot reference manual.

Keep in mind that the Start-up Guide is not a complete way to become familiarized with the Pellet

Pro® Patriot. It is recommended that users read through the Pellet Pro® Patriot reference

manual in its entirety to become knowledgeable about unit’s operation and functionality.

Initial Start-up (No Pellets in the Auger)

1. Connect the Pellet Pro® Patriot to an outlet and wait for the version number to be

displayed on the OLED display.

2. Open the lid/door of your cooking unit –the lid must remain open through step five.

3. Press the “ON/OFF” switch located on the face of the controller – this will begin RTD

probe calibration to monitor temperature. When calibration is completed, the Pellet Pro®

Patriot will enter Standby where only the fan will run.

4. While in Standby, press the “Feed” switch to prime the auger tube for your first cook.

Once pellets begin to fall into the burn pot, you may select your desired mode, or,

temperature

5. After smoke becomes visible and then clears, close the smoker lid/door.

Subsequent Start-up

1. Connect the Pellet Pro® Patriot to an outlet and wait for the version number to be

displayed on the OLED display.

2. Open the lid/door of your cooking unit –the lid must remain open though step five.

3. Press the “ON/OFF” switch located on the face of the controller – this will begin RTD

probe calibration to monitor temperature. When calibration is completed, the Pellet Pro®

Patriot will enter standby where only the fan will run.

4. Once in standby, you may select your desired mode, or, temperature.

5. After smoke becomes visible and then clears, close the smoker’s lid.

It is important to note that all start-up operations are to be completed with

the smoker open until visible smoke appears and clears. Failure to do so can lead to large

smoke accumulation in the grill body –under these conditions, it is possible for explosive

combustion to occur.

1. Preface

Early in the Spring of 2018, Smoke Daddy Inc. began the process of designing a newly

envisioned Pellet Pro® PID Controller with Wi-Fi capability. With the positive, long-

established, reputation of Smoke Daddy Inc. products, the goal of customer satisfaction was at

the forefront of every preliminary discussion regarding the development of this controller. In

order to fully satisfy the standards of this project, while also providing a far superior BBQing

experience, Smoke Daddy Inc. committed the new Pellet Pro® PID Controller to be designed,

engineered, and manufactured in the United States of America. Thus, began a collaborative effort

between small businesses in the Midwestern United States to undertake this project - not only to

revolutionize our Pellet Pro® PID Controller, but to revolutionize pellet grills by setting the

standard in performance, quality, and user-experience.

Over the span of nearly two years, our team at Smoke Daddy Inc. has spent countless hours

deliberating, developing, and testing software solutions to incorporate into the new Pellet Pro®

PID Controller. By evaluating the strengths and shortcomings of our first Pellet Pro® PID

Controller, we have developed robust temperature controlling algorithms that utilize not only

closed-loop PID systems, but also timed-cycles that control external motor function in non-PID

operating modes. Moreover, by using the industry’s most innovative microcontroller, we

seamlessly bridged the gap between Computer Science and the art of BBQ to provide the best

mathematical solution to temperature swings and inconsistent cooks.

It is important to note that the wire colors on external components are

independent of the wire colors on the Pellet Pro® Patriot wiring harness. i.e.

the green fan connector on the Pellet Pro® wiring harness may not be connected to another

green wire.

2. Definitions

Auger Motor: An external component located in the hopper assembly that receives power and

instruction from the Pellet Pro® Patriot. This device augers fuel (wood or charcoal pellets) into

the burn pot to be ignited by the hot rod.

Burn Pot: A reservoir to catch pellets as they auger into the body of a pellet grill, this is where

fuel combustion occurs via the hotrod.

Fan Motor: An external component located in the hopper assembly that receives power and

instruction from the Pellet® Pro Patriot. This device provides airflow into the burn pot ensure

efficient combustion.

High Mode: A mode of operation by which the fan motor and auger motor both operate at 100

percent capacity. High mode is designed to allow your pellet grill to operate at its highest

possible temperature.

Hot Rod: An external component in the burn pot that receives power and instruction from the

Pellet Pro® Patriot. This device ignites wood or charcoal pellets for startup routines during

operation.

Low (Hold) Mode: A mode of operation by which the auger motor operates on a timed cycle.

Low (Hold) mode is designed to allow your pellet grill to operate at its lowest possible

temperature.

Meat Probe: An external component that is connected to the face of the Pellet Pro® Patriot.

This is a temperature recording device that is intended to provide the user with information about

meat temperatures inside the body of the grill.

Microcontroller: An integrated computing device on a control board that provides instruction to

external and internal components during operation. This device allows the PID algorithm to

communicate with the fan and auger motors.

Molex Connector: A “pin and socket” connector that allows the Pellet Pro® Patriot to transmit

electrical power to external components.

OLED Display (Monochrome): The 128x64 pixel display that is used by the Pellet Pro®

Patriot to provide information about your cook such as: hot rod usage, Fine-Tuning, set

temperature, current temperature, meat temperature, and more.

PID control: A method of control that receives measured input and calculates an output to

modulate external components. Changes in power settings are based off deviation (proportion)

from set point as well as the rate of change (derivative) of temperature.

Page 4

Quick Mid: A mode of operation by which the fan motor and auger motor both operate via the

PID algorithm. Quick Mid is a shortcut to set the control temperature to 270F.

Resistance Temperature Device (RTD): An external component located in the body of a pellet

grill that measures resistance –this reading is transmitted to the Pellet Pro® Patriot and

converted into temperature readings.

Wi-Fi Provisioning: The process by which an end-user establishes communication between the

Pellet Pro® Patriot and a mobile device.

Wiring Harness: The assembly of electrical wires that are used to transmit electrical signals and

power.

3. Summary of Operation

During operation, the Pellet Pro® Patriot will utilize a PID control algorithm or a timed cycle to

maintain a specified temperature set point within five to ten degrees.

3.1 Start-up

The Pellet Pro® Patriot provides a dedicated, timed, start-up cycle that allows the user to set

their desired temperature immediately (see caution). During start-up, the fan motor will always

operate at 100 percent capacity below 150°F and the auger motor will operate at 100 capacity but

has a timed cycle of 90 seconds (60 seconds off, 30 seconds on).

It is important to note that all start-up operations are to be completed with

the smoker open until visible smoke appears and clears. Failure to do so

can lead to large smoke accumulation in the grill body –under these conditions, it is

possible for explosive combustion to occur.

3.2 Temperature Readings

During operation, the Pellet Pro® Patriot will receive temperature readings every .10 second and

average the collected data to provide quick, yet accurate, temperature readings to both the user

and temperature controlling algorithms. These temperature readings are received from a PT1000

RTD probe that is fastened into the body of your pellet grill.

3.2 Temperature Readings (cont.)

It is important to note that the Pellet Pro® Patriot will enter an error state if inaccurate data is

received from the RTD probe.

3.3 Temperature Controlling

The Pellet Pro® Patriot utilizes two methods of temperature controlling, timed and PID control,

that are utilized at different times dependent on the current mode of operation.

PID control: The Pellet Pro® Patriot PID algorithm will be utilized at set temperatures between

200F-450F. Every two seconds, the temperature controlling algorithm will receive the current

grill temperature as a parameter and adjust both the fan and auger motor power settings.

It is important to note that the fan motor will never have a power setting of zero, meaning, air

will always be provided to the burn pot.

Page 6

Timed control: The Pellet Pro® Patriot timed cycle control will only be utilized while the

controller is set in Low (Hold) mode, or, start-up modes. Timed control provides consistent low

temperature holding capability as well as intermittent, thin, smoke.

3.4 Shutdown

The shutdown cycle occurs over a 15-minute period where the fan motor will operate at 100

percent capacity and no additional external components will receive instructions. This routine is

intended to extinguish any fire in the burn pot. During the last 30 seconds, the auger motor will

operate at 100 percent capacity.

3.4 Shutdown (cont.)

It is important to note that the shutdown routine should be completed with

the smoker lid open for the entire duration of shutdown. Failure to do so may

disallow the fuel in the burn pot to fully extinguish.
