Package List: 1 x Freezer Temperature Controller Note: Danger 1: Strictly distinguish between sensor leads, power lines, and output relay interfaces to prevent wrong connections. The power supply voltage should not exceed the rated voltage range of ± 10%. Danger 2: Wiring connections must be made with the power off.Warning 1: This device is prohibited from being used in environments with continuous water spray, excessive humidity(relative humidity >90%, condensation may occur), Warning 2: Prohibited from being used in high temperature, strong electromagnetic interference, and highly corrosive environments. Attention 1: The power supply voltage should be consistent with the voltage marked on the machine, and ensure the stability of the power supply voltage. Attention 2: To avoid potential interference, it is recommended to keep a proper distance between the sensor leads and power lines. Attention 3: When installing the evaporator sensor, the sensor should be placed close to the copper pipe 5cm away from the evaporator inlet, ensuring good contact between the sensor and the copper pipe.
