PURPOSE:To alleviate manpower of a site worker upon attaching and detaching of a humidifier to or from a refrigerating unit of a container and to prevent a trouble due to forgetting of its transfer. CONSTITUTION:The controller for a refrigerating unit of a container comprises a diffusing air temperature sensor 42 provided at a humidifier 30, contact switching means 40 connected with the sensor 42 and a diffusing air temperature sensor 13 provided at the unit to switch to connect it to the controller 20, and power source input judging means 41 for the humidifier to drive the means 40. Thus, since the temperature sensor connected to the controller 20 is automatically switched from the sensor 13 provided at the unit to the sensor 32 provided at the humidifier 30 upon mounting of the humidifier 30, a transfer of the sensor 13 to be conducted at each time of attaching and detaching the humidifier 30 in a conventional unit is eliminated, manpower of a site worker can be alleviated, and a trouble due to forgetting of the transfer can be prevented. |
