Description of heating mode:When the detected temperature (current temperature)≤Set temperature-Hysteresis temperature, the relay turns on and the heating device starts to work; When the detected temperature (current temperature) ≥ the set temperature, the relay is disconnected and the heating device stops working; set the temperature to 30 ° C and the hysteresis temperature to 5 ° C. 0 °C; Through this correction function, the current temperature = measured temperature + calibration value. Emergency braking function (emergency stop function): after activating the emergency stop, the relay will be disconnected no matter what state it is in; After turning off the emergency stop, the relay will return to its normal state; Automatic mode function description: first select the heating mode/cooling mode; Set the temperature and hysteresis, if you need to delay the , then set the delay time; Then set the high and low temperature alarm on your own. when the temperature is 20℃≤25℃(30-5=25), the relay starts to heat up, when the temperature reaches 30℃≥ set temperature 30℃, the relay turns off and stops heating; after a heating/cooling process ends, how much the delay (unit: second) to allow the next warming/ cooling; temperature correction function: the works for a long time and deviations may occur. Cooling mode description When the detected temperature (current temperature) ≥ set temperature + hysteresis temperature, the relay turns on and the refrigeration equipment starts to work; Example: set the temperature to 30 ° C and the hysteresis temperature to 5 °C; when the temperature is 36 ° C ≥ 35 ° C (30+5=35 ° C). 5), the relay is to start cooling, and when the temperature reaches 30°C≤the set temperature 30 ° C, the relay turns off and stops cooling;, Weight: 0.07165023515 Pounds, Manufacturer: Faeymth
