XY-T01 High Precision Digital Display Temperature Controller Module

Model: YZQ-D004
Product functions:
1. Heating mode ‘H’:
When the detected temperature ≤ set temperature – hysteresis temperature, the relay is turned on and the heating equipment starts working;
When the detected temperature ≥ set temperature, the relay is disconnected and the heating equipment stops working;
2. Cooling mode ‘C’:
When the detected temperature ≥ set temperature + hysteresis temperature, the relay is turned on and the cooling equipment starts working;
When the detected temperature ≤ set temperature, the relay is disconnected and the cooling equipment stops working;
3. High temperature alarm function ALA:
When the actual temperature ≥ alarm temperature, the system turns on the sound and light alarm, and disconnects the relay, and any key stops the sound and light;
4. Delay start OPH:
After completing a normal heating or cooling work, the system starts timing T. Only when T ≥ OPH, the system can carry out the next round of heating or cooling work;
