Temperature Controller Function Manual 1. Function: External temperature detector detects temperature, can set on and off temperature, and has cyclic timing, timed on, timed off. Timed switch function is widely used for intelligent temperature control in places such as coal crystal heating, aquaculture, greenhouses, and home life. 2. Real-time temperature range: -40~120 * C 2.1 Open circuit (or less than 45C), the first line on the screen flashes and displays "E1" -40-45C, displays -40C. 2.2 Short circuit (or greater than 120'C): The first line on the screen flashes and displays "E2". 121-129C displays 120C. 2.3 Values below -10C or above 100'C are not displayed after the decimal point. 2.4 Cooling mode, when the set start temperature is higher than the stop temperature, it is called cooling mode and displays the corresponding icon. 2.5 Heating mode, when the set start temperature is lower than the stop temperature, it is heating mode and displays the corresponding icon. F01 cyclic timing mode, works in a loop according to start time (on)/stop time (off). F02 timed on mode, currently in off mode (delayed) on. When it runs to OFF, the relay is turned off and the socket has no output, and the indicator light is off. Setting Button (SET): 3.2.1 Temperature control mode, short press the setting button to switch between start and stop temperature settings, temperature range -40~120'C (Default start temperature is 20C and shutdown temperature is 25C when turned on). 3.2.2 Timer mode (F01~F04) Short press the setting button to switch between start time hour, minute/stop time hour and minute settings, with a setting range of 0~99 hours and 59 minutes. 3.2.3 During operation, it is allowed to adjust the temperature/time by pressing the setting button. 3.3 Add/Subtract Keys (UP, DOWN) 3.3.1 When the value is flashing, press the plus or minus buttons to adjust the value. 3.3.2 Short press once to add/subtract 1 value, long press to automatically add/subtract time value. 3.3.3 When not in operation, press the up and down buttons simultaneously for 3 seconds to restore factory settings. 4. Temperature correction function: 4.1 Press and hold the power button in long press mode, and after 2 seconds, enter real-time temperature calibration. The first line on the LCD screen displays "CALIBRATION" and real-time temperature, the second line of the LCD screen flashes the correction value, adjust the correction value by pressing the up and down buttons (according to the adjustment) The calibration value and real-time temperature also change accordingly. 4.2 Real-time temperature correction range -9.9-9.9C. 4.3 Long press the "SET" button or press it for 5 seconds to automatically exit without saving any changes. Long press the "MODE" button to exit and save the current calibration changes. 5. Screen lock protection function Press the "MODE" and "SET" buttons simultaneously for more than 3 seconds to switch the screen lock function. When the screen is locked, the buttons are invalid. 6. Memory function: After power failure, all current settings are saved. 7. Factory check: Press the RESET button under the LED light with a sharp object like a pen tip to restore the screen to full display for 1 second. Factory settings. 8. Technical parameters: 1. Rated voltage: 230VAC 50HZ 2. Rated load: MAX 16A36
