Package List: 1 x Temperature Controller 1 x Probe Wiring Note: 1. The power supply voltage should be consistent with the voltage marked on the machine, and the deviation between the power supply voltage and the rated voltage value should not be greater than ±10%.2. The sensor should keep an appropriate distance from the power cord, and try to avoid contact or approach.3. Strictly distinguish the sensor, power line and output relay interface.4. Pay attention to the correct operation.
