Calibrating the Pellet Sensor
When installing a pellet sensor, you may need to calibrate it. Follow the following steps:

  1. After powering on the grill, you should see a message ""Calibrate your pellet sensor for accurate results."" Select ""Calibrate now.""
  2. Empty the pellets from your hopper. Then select ""OK.""
  3. Place your hand under Pellet sensor to block light then Press ""OK. ""

The controller will walk you through the full calibration process. If the controller doesn't automatically start the calibration on startup, you can access the Pellet sensor calibration by selecting the menu button > selecting Settings > pellet sensor, which will bring you to the calibration page.


  • Ensure the grill being used is compatible.
