T3: Push Button Test	Press any button on the control and a digital display feedback confirms the button is working.
T4: All On Display Test	Press any of the product buttons and every LED on the 16 digit display lights.
T5: Segments Test	Repeatedly pressing any product button lights one segments in every one of the 16 digit displays.
T6: Digits Test	Repeatedly pressing any product button lights all segments in one of the 16 digital displays. (Scrolls though all 16.)
T7: Decimal Points Test	Repeatedly pressing any product button lights a decimal point (DP) in one of the 16 digital displays. (Scrolls though all 16.)
T8: LED'S Test	Repeatedly pressing any product button lights individual LEDs. (Scrolls though all LEDs.)
T9: Air Temperature - Circuit Calibration	Factory use.
T10: Air Temperature - Calibration/Offset/Highest	This is a user calibration to make sure the display shows the actual air temperature. Press and hold the 1 button and use the Down arrow button and the Up arrow button to set the display to match the actual temperature. (+/-15° F) Press and hold the 2 button to change the amount of the offset.(+/-15° F) Press and hold the 3 button to view the highest air temperature recorded. Press the Down arrow button to reset highest temperature.
T11: Water Heater Temperature - Circuit Calibration	Factory use.
T12: Water Heater Temperature - Calibration/Offset/ Highest	This is a user calibration to make sure the display shows the actual water heater temperature. Press and hold the 1 button and use the Down arrow button and the Up arrow button to set the display to match the actual temperature. (+/-15° F) Press and hold the 2 button to change the amount of the offset.(+/-15° F) Press and hold the 3 button to view the highest air temperature recorded. Press the Down arrow button to reset highest temperature.
T13: Food Probe Temperature - Circuit Calibration	Factory Use.
T14: Food Probe Temperature - Calibration/Offset/Highest	This is a user calibration to make sure the display shows the actual food temperature, when using the food probe. Press and hold product button 1 and use the Down arrow button and the Up arrow button to set the display to match the actual temperature. (+/-15° F) Press and hold product button 2 to change the amount of the offset. (+/-15° F) Press and hold product button 3 to view the highest air temperature recorded. Press the Down arrow button to reset the highest temperature.
T15: Humidity - Circuit Calibration	See Calibrating and Replacing the Humidity Sensor.
T16: Humidity Sensor - Calibration/Offset	This is a specific value that is sent with the humidity sensor, when necessary. Otherwise, this value should be 0.
T17: Humidity - Calibration/Offset/Highest	This is a user calibration to make sure the display shows the actual humidity inside the cabinet. Press and hold the 1 button and use the Down arrow button and the Up arrow button to set the display to match the actual humidity. (0 to 100%) Press and hold product button 2 to change the amount of the offset.(-0 to-99) Press and hold product button 3 to view the highest humidity recorded. Press the Down arrow button to reset highest humidity.
T18: CPU° - Control Temperature - Highest Value	Press the 1 button to show the highest temperature to which the control board was exposed.
T19: View ADC Channel	Factory use.
T20: Outputs/Inputs	The following components can be tested: Product button 1 toggles the vent motor off and on. Product button 2 toggles the cooling fan off and on. Product button 3 toggles the water heater off and on. Product button 4 toggles the air heaters off and on.
T19: Total Initialization	This completely resets any accumulated information and changed settings in the controls. Contact Henny Penny before completing this step.
