PROBLEM TO BE SOLVED: To simply and effectively execute functional allocations of sensors provided in an equipment in a main control means by starting an operation of the equipment and then conducting the allocations of the sensors based on transitions of data from the sensors. SOLUTION: A control box 9 is connected to an AC power line 21 and a signal line 22. An indoor temperature sensor 27 for detecting a temperature in a storage chamber 3, a defrost sensor 10 for detecting a temperature of a cooler, a high temperature sensor 20 for detecting a temperature of a condenser, and switching elements 28 mounted at a drive board 23 and power source boards 24, 26 are connected to the line 22. The control means 9 starts an operation of an equipment and then conducts functional allocations of the sensors 27, 10, 20 based on transition of data of the sensors 27, 10, 20. Thus, the functional allocation of the connected sensors 27, 10, 20 can be conducted without specifying ports when connected. Accordingly, productivity of the equipment can be improved. |
