Abstract
Methods and systems are provided for determining an active response during cold treatment of refrigerated cargo during shipment of a refrigeration container. Steps include: receiving a set point adjustment protocol for modifying set points of a refrigeration controller of the refrigeration container; during a period of active response operation, receiving temperature signals from a plurality of temperature probes located in the refrigeration container; determining that one or more of the received temperature signals exceeds a temperature threshold defined by the set point adjustment protocol; determining that a temperature trend of the one or more of the received temperature signals meets a trend trigger of the set point adjustment protocol; and, responsively to the temperature threshold and the trend trigger, transmitting a set point change command to the refrigeration controller.
