御装置。[Claim for Utility Model Registration] A first comparison means that outputs a signal when the temperature inside the open showcase falls below a set value, and a signal output from the first comparison means of the snake is input. In a temperature control device for an open showcase that is equipped with an alarm device that issues an alarm, the output signal of the sensor that detects the temperature number outside the open showcase is compared with the set signal, and the output signal is determined as above. Outputs a signal when the signal drops below the set signal.
and a gate circuit that prohibits the signal output from the first comparison means from being input to the alarm device in response to the output signal of the second comparison means, When the temperature inside the open showcase store decreases due to a decrease in the temperature outside the showcase, the signal output from the first comparing means is prohibited from being input to the alarm device. An open showcase temperature control device characterized by:
