"trEAt" is the maximum value that the USDA probes need to remain below, to pass the Cold Treatment pro-
tocol. For instance, if the treat value is set at 35.0°F (1.7°C) then the USDA probe temperatures must
remain below 35.0°F (1.7°C) to pass.
6. "dAyS" is now displayed in the left display and the right will be flashing. Use the Arrow keys to select the
desired days for cold treatment and press the ENTER key.
7. "ProbE" is now displayed in the left display and the right will display the probe numbers that are connected.
Press the ENTER key. For instance, if "1234" is displayed, then all four of the probes are connected.

Once the cold treatment process has been initiated, setpoint change via the keypad is disabled.
11. While the unit is operating in ACT mode, the left hand display will alternate between "COLd" and setpoint.
The right hand display will alternate between "trEAt" and the cargo temperature. Once the treatment time
