PURPOSE:To enhance the operability of a controller by a method wherein a temperature set point holding circuit and a temperature setter are provided for each of a plurality of terminal devices, and the temperature set point for an apparatus to be controlled can be set both at the center and at a terminal. CONSTITUTION:The set point holding circuits 9a-9n are connected to respective control circuits 5a-5n of a plurality of a refrigerators and air conditioners 7a- 7n, and the temperature setters are connected to the holding circuits 9a-9n. Accordingly, the temperatures of the plural refrigerators and air conditioners 7a- 7n can be set both by the temperature setter 2 on the CPU side and by the temperature setters 10a-10n on the terminal device side. |
