In the design of the refrigeration machine control box, when the gas is released, the machine is stopped because the amount of freezer is expensive. That is, the heater magnet (MH) to eliminate the defrost in the freezer unit cooler is operated within 6 to 8 hours due to the operation function of the freezer. Therefore, the temperature keeps rising in the internal freezer.

For example, it is loaded with more than 100 million won of ice cream at 15 pyeong. If you go to work on Saturday, Sunday or non-working day, you will not be able to sell the frozen products due to abnormal products. Therefore, when the contact is normally attached and the MY-relay contact is dropped when the Freon gas is removed, the unmanned security system of the present invention is operated as shown in Figure 1 is automatically connected.
