Claims

[Scope of Utility Model Registration Claim] In a temperature controller equipped with a temperature display on the panel surface that serves both to display the set value of the regulated temperature and the measured value of the currently measured temperature, a set value display mode and a measured value display mode are provided. A display switching operation section for switching, a set value display mode indicator, and a measured value display mode indicator are provided in the temperature display or on an appropriate panel surface, and settings are made in response to a switching operation of the display switching operation section. A display switching circuit that outputs a set value display switching signal in the value display mode and a measured value display switching signal in the measured value display mode, and a first timer signal corresponding to a predetermined timer time in the set value display mode. a timer that outputs a second timer signal corresponding to a predetermined timer time in the measured value display mode, and the set value display mode indicator when a set value display switching signal is given from the display switching circuit. in response to a first timer signal from the timer, and when the measured value display switching signal is given, drive control of the measured value display mode indicator in response to a second timer signal from the timer. A temperature controller characterized by comprising: a control circuit for controlling the temperature;
