Document Type and Number:
Japanese Patent JP3913461
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To automatically and correctly deal with the situation when communication between a controller and a temperature sensor can not be effected normally, in an absorption type water cooling and heating machine permitting the wiring of the temperature sensor through plug-in connection.
SOLUTION: The absorption type water cooling and heating machine, equipped with a controller 40 which cancels a transmitted temperature data and requires transmission through a communication line 39 after re-measurement when temperature sensors 42-50 installed in respective sections of the absorption type water cooling and heating machine have measured and transmitted a temperature within a range which can not be measured originally, is provided. The controller 40 can be provided with a function (1) to give an alarm by indicating the number or the like of a temperature sensor that has transmitted the abnormal temperature data in an indicator 41 or (2) to control the temperature sensor, which transmitted the abnormal temperature data, to make the A/D converter 247 restore the initial condition of the same, when the abnormal temperature data are measured and transmitted by the predetermined number of times repeatedly by the same temperature sensor.
