✔ Temperature controller system power input: DC 12V; temperature control range: -55°C to 120°C; temperature measurement accuracy: 0.1°C; refresh rate: approximately 0.5s. Sensor wire: 1 meter ✔ Dimensions: 79*43*26mm; cutout dimensions: 76*39mm. Manual download: Please enter all characters enclosed in brackets (http://8.217.75.21/Industrial/Multilingual/CBAA0029-018_UK.pdf) ✔ Multiple Functions: Selectable cooling or heating operating mode, with a °C/°F switch function, adaptable to different scenarios. P0-P9 has 10 parameter/function settings. (Note: Please contact us if you have any questions.) ✔ Cooling/Heating: After setting parameters such as heating/cooling mode, start temperature, and temperature differential according to the manual, the device automatically controls the cooling/heating function when the set conditions are met. ✔ Temperature Calibration: If the temperature controller's measured temperature deviates, the temperature can be calibrated as needed for accurate temperature control. ✔ Alarm function: When the temperature reaches the set temperature, the controller will alarm (-55~120℃). You can also set the maximum/minimum upper limit temperature to avoid accidents. (For more functions, please refer to the detailed description or instruction manual)
