Akozon Digital DC 12V Dual LED Display Temperature Controller Sensor Relay Module Thermostat Switch

Specifications: Control Range: -50?~110? Control Precision: 0.1? Temperature Alarm: -49?~110? Input Voltage: DC12V Output Type: Relay output max. 10A Return Difference Set: 0.1~30? Delay Start: 0~10minutes Temperature Correction: -10?~+10? Red Display: Measured Temperature Green Display: Setting Temperature P1 Return Difference: Press and hold SET button to enter internal setting, select P1 setting, press the SET button again to set return difference value. (Return difference value is the value that controller restarts after it reached set temperature and stopped. For example, if we use heating mode, make controller stops at 40? and restart at 35?, the return difference value is 5) P2 Temperature Correction: This function is used for temperature correction, if there is a deviation between measured temperature and real temperature. Correcting Temperature= Measured Temperature + Correction Value.  For example, if the measured temperature is 25.6 degrees and the actual temperature is 25.8 degrees, set P4 as 0.2, so the final temperature is 25.6 + 0.2 = 25.8 degrees Heating mode setting example: Control electric heating equipment to stop heating at 35?, and restart when temperature is down to 30?; 1, Press and hold SET button for 3 seconds to enter internal setting, set P0 as H. 2, Press and hold SET button to return to the real-time temperature display, press SET button again and the green display flashes, then adjust the value to 35?. 3, The default return difference is 2, it need to be set as 5 if want to restart at 30?. Press and hold SET button to enter internal setting, select P1, change P1 value to 5. Package Includes: 1 x Temperature Controller
