Features:* If the temperature detected by the temperature sensor is over 130'C or the temperature sensor is short-circuited, it will display "E-1"* If the temperature detected by the temperature sensor is lower than -30 deg; c or disconnected temperature sensor, it will display "E-2"* Temperature measurement sensor parameters: 10k/25" C3950k* Temperature setting:* "Up and down" press these two keys to adjust the starting temperature; "up and down" ", press these two keys to adjust the stop temperature;* The working modes include heating mode and cooling mode:* Heating mode: start temperature stop temperature* When the real-time temperature is lower than the start temperature, there is power output. As long as the time temperature the real-time temperature will not be higher than the stop temperature, turn off the output power.* Cooling mode: start temperature stop temperature* When the measured temperature is higher than the start temperature, there is output power. Until the real-time temperature is lower than the stop temperature, turn off the output power. * Temperature correction: * Press and hold "up and down" for 3 seconds at the same time "and" flashalternately. The correction value is 0. Use these two keys to correct the real-time temperature to -9.9-+9.9", * Restore factory settings: * Press and hold "up and down" simultaneously for 3 seconds to clear the set start temperature , stop temperature and temperature correction value.
