Operating Modes of the Product
Heating mode "H":
When the detected temperature is lower than or equal to the set temperature - hysteresis temperature, the relay opens and the heating device starts to operate;
When the detected temperature is equal to or greater than the set temperature, the relay is disconnected and the heating device stops working;
Cooling mode "C":
When the detected temperature is equal to or greater than the set temperature + hysteresis temperature, the relay opens and the cooling equipment starts to work;
When the detected temperature is lower than or equal to the set temperature, the relay is disconnected and the cooling equipment stops working;
High temperature alarm function ALA:
When the actual temperature is equal to or greater than the alarm temperature, the system will turn on the sound and light alarm and press any key to stop the sound and light;
Delayed start OPH:
When a normal heating or cooling operation is completed, the system starts timing T. However, only after T greater than or equal to KOH, the system can perform the next heating or cooling operation;
Temperature correction function OFE (-10.0 ~ 10.0 degrees Celsius):
The system may operate for a long time and deviations may occur. This function is corrected by actual temperature = measured temperature + calibration value;
Parameter remote reading / setting:
Starting temperature, stop temperature, temperature correction etc. Parameters such as can be set from within the UART;
Temperature real-time reporting:
If the temperature reporting function is enabled, product detection It transmits the measured temperature to the terminal via UART at 1 s intervals;
Relay active (default on):
If the relay is closed, the relay remains closed;
Restore factory settings:
STOP at the same time , press SET 3S or more to restore factory settings.
