Thank you! Note: 12V/220V wiring method is actually the same, 12V wiring needs to distinguish betweenpositiveand negative, 220V wiring needs to distinguish between live wire (L) and neutral wire (N) Operating Instructions SET function switch / switch machine In the power-on state, press and hold the SET button for 3 seconds to turn on and off the machine. In the off state, press the SET button to turn on During normal use, press the SET button to perform F-1 (intermittent work), F-2 (timed shutdown), F-3 (timed start), function switching (F1-F3 are additional functions used, and temperature control The setting doesn't matter, so don't use it) F-1 Intermittent work Left start minute setting Right stop minute setting F-2 timed shutdown, left hour, right minute, maximum can be set to 99 hours and 59 minutes F-3 timed power on, left hour, right minute, the maximum can be set to 99 hours and 59 minutes temperature calibration Eight times the thermostat plug, press and hold the SET button to power on, enter the temperature correction function, the screen displays - -000- -, you can add or subtract the temperature based on the temperature before the correction. Maximum range -9.9C, after calibration, real-time temperature = temperature value before calibration + calibration value Self-check function Press and hold the left start temperature setting button at the same time, do not let go up and down, then power on, you can enter the self-test function factory reset Press and hold the right change stop temperature setting button at the same time and do not send it up and down, then turn on the power, the screen displays 88-888-88, the buzzer beeps for a long time, and the factory reset is completed. _x000D_
