Setup Guide: Predictive Thermometer

Congratulations, cook!

You are now in possession of the most advanced (and frankly, best) wireless thermometer ever made.

With its array of 8 sensors, the Combustion Predictive Thermometer (CPT for short) automatically finds and tracks the lowest internal temperature of the food you’re cooking.

Once you’ve chosen a target temp and start cooking – it calculates the exact time remaining to reach that temperature. If the heat changes, the prediction corrects itself. All of these calculations are done inside the thermometer!

Before you start cooking, there are a few things you’ll need to do to make sure your CPT is set up properly and ready to go.

  • Charge your tools

    Charge the CPT (25 min).

    Use USB-C-to-USB-A (cable included).

    The GREEN light on the charger lets you know when it's ready.

    If it's RED or AMBER, it's still charging.

    • Please use standard USB ports/power supplies.
    • High-quality chargers such as Apple/Android/Meta are fine (they won’t put out extra voltage unless the device asks for it).
    • "Quick Charge" ports will not charge it faster.
    • You can use a USB-C to USB-C cable as long as the power supply is stable and within specs.
    • Avoid low-quality ports especially cheap power strips. They can put out erratic voltages that can overload the protection circuitry.
    • Never use the "Signals" adapter from Thermoworks - it's a 12v supply and will destroy any standard USB device, including Combustion tools. Eek!
  • Update firmware

    • Always recharge your Predictive Thermometer fully before applying any firmware update.
    • Download the "Combustion Inc" app from the App Store for iOS or Google Play for Android. 
    • Remove the CPT from the Booster or Charger (this turns the CPT on and allows it to connect to the app)
    • Open the settings menu inside the app by tapping the Combustion logo then tap "update.” 
    • Recharge your CPT after the update (it can eat a lot of power).

    Note: please do not update more than one CPT (or other Combustion tool) at the same time. Leave the other ones powered off (or in standby) while you update. It won't take long!

  • Link Display

    • Update Display firmware (same steps as above)
    • Turn on the Display by pressing the Start/Stop button
    • Turn on CPT by removing it from the charger
    • Place CPT next to the display for a few seconds
    • When a temperature appears on-screen, that means they’re linked
  • Call out of location of minimum insertion line (about halfway down the thermometer).

    Warnings!

    • Insert to at least the min line.
    • Keep the tip out of superheated fluids (oil, candy, etc).
    • Avoid direct flame - it can easily exceed max temp.
    • Never microwave!
    • Tip is extremely pointy.
    • Always recharge your CPT fully before updating the firmware.
