- Set the temperature—-SetT;
- Back temperature—–back;
- Heating mode ‘ H ‘ :
When temperature ≤ sett-backt; Relay driving, the heating equipment starts to work;
When the temperature ≥ SetT, relay disconnection, the heating equipment stops working;
When temperature ≥ SetT BackT; Relay driving, the refrigeration equipment starts to work;
When temperature ≤ SetT; Relay driving, the refrigeration equipment stops working;.
- High Temperature Alarm ‘ ALA ‘ :
When the temperature ≥ the alarm temperature, the system opens the sound and light alarm, and disconnects the relay, any key stops the sound light;
When normal heating or cooling work is done, the system starts at time T, and only after t≥ Oph, the system can do the next round of heating or cooling work;
- Temperature correction functionOFE (-10.0~10.0°):
The system will work for a long time and may have deviations that can be corrected by this function, temperature = measurement calibration;
- Remote parameter reading/setting:
Parameters such as temperature setting, back tab temperature and temperature correction can be set via UART.
- Real time temperature report:
If the temperature report function is turned on, the product is sent to the terminal by the UART at intervals of 1s, which facilitates data collection;
- Relay activation (default activation):
If the relay is off, the relay remains off;
At the same time press STOP, set the key more than 3S, restore factory settings;
