Abstract

PURPOSE: To facilitate wiring construction by providing terminal devices, provided with functions of A/D conversion and of driving refrigerating sources, at sides of equipments whose temperatures are to be controlled and by connecting them in series to CPU.
CONSTITUTION: Central processing unit CPU1 transmits and receives information to and from terminal devices 51W5n provided to equipments 21W2n whose temperatures are to be controlled. From CPU1, terminal devices are selected via address assignment signal line A. Each terminal device compares a read signal with an address, set in address setting circuit 6, by coinciding circuit 7 and when both coincide with each other, the analog signal of temperature detector 31 is A/D-converted 9 into a digital signal, which is read by CPU1 via signal line B. The read measured temperature value is compared with a set value preset in CPU and refrigerating- heating source 41 of equipment 21 is controlled via refrigerating-heating source driving circuit 9 of the terminal device by way of signal line C. From CPU1, devices 51W5n are selected and controlled periodically in sequence. Thus, CPU can be connected in series to equipments 21W2n and the wiring construction is facilitated.
