5.12 Automatic Cold Treatment (Option)
Cold Treatment has been employed as an effective post-harvest method for the control of Mediterranean and certain
other tropical fruit flies. Exposing infested fruit to temperatures of 2.2°C (3.6°F) or below for specific time periods
results in the mortality of various life stages for this group of insects.
Automated Cold Treatment (ACT) in the Carrier Transicold unit is a method to simplify the task of completing cold
treatment by automating the process of changing the setpoints. ACT is set up through function code Cd51. Refer to
Function Code table in this manual for Cd51 menu processing and displays.
NOTE
ACT, setup with Cd51, and Automatic Setpoint Change (ASC), setup with Cd53, will not work simultane
-
ously. Setting one will deactivate the other.
Procedure to Set ACT:
1. Enter the required cargo setpoint. It must be lower than the treatment temperature discussed in step 5.
2. Press the CODE SELECT key.
3. Use the Arrow keys to scroll to Cd51, and then press the ENTER key.
4. "ACt" is now displayed in the left display and the right will display "Off". Use the Arrow keys to bring up "On"
in the right display and press the ENTER key.
5. “trEAt" is now displayed in the left display and the right will be flashing the last setting (shown as XX.X°C).
Use the Arrow keys to select the desired cold treatment setpoint and press the ENTER key.
