XY-WT01 Temperature Controller Digital LED Display Heating/Cooling Regulator

XY-t01 digital temperature controller high precision digital display temperature controller module refrigeration and heating
Product functions:
1. Heating mode 'H':
When the detection temperature ≤ the set temperature - return difference temperature, the relay is turned on and the heating equipment starts to work;
When the detection temperature is ≥ the set temperature, the relay is disconnected and the heating equipment stops working;
2. Cooling mode 'C':
When the detection temperature is ≥ the set temperature + return difference temperature, the relay is turned on and the refrigeration equipment starts to work;
When the detection temperature is ≤ the set temperature, the relay is disconnected and the refrigeration equipment stops working;
3. High temperature alarm function ala:
When the actual temperature ≥ the alarm temperature, the system starts the audible and visual alarm, disconnects the relay, and any key stops the audible and visual alarm;
4. Delayed start of OPH:
After completing a normal heating or cooling work, the system starts to count T. only when t ≥ OPH, the system can carry out the next round of heating or cooling work;
5. Temperature correction function ofe (- 10.0 ~ 10.0 ℃):
If the system works for a long time, there may be deviation. Through this function, the actual temperature = measured temperature + calibrated value;
6. Remote reading / setting of parameters:
Start temperature, stop temperature, temperature correction and other parameters can be set through UART;
7. Real time temperature reporting:
If the temperature reporting function is enabled, the product will transmit the detected temperature to the terminal through UART at an interval of 1s for data acquisition;
8. Relay enable (default on):
If the relay is enabled, the relay remains disconnected;
9. Restore factory settings:

Press stop and set for more than 3S at the same time to restore the factory setting;

Operating mode / setting temperature / return difference temperature setting:
1. In the operation interface, briefly press the set key to enter the quick setting interface;
2. After entering the quick setting interface, briefly press the set key to switch the parameters to be set (working mode / set temperature / return difference temperature);
3. Use the up down key to modify the parameter value, and support short press / long press;
4. Press and hold set for more than 3S or for 6S without any key operation, exit the quick setting interface and save the parameters;

Alarm temperature / delay start setting / temperature correction:
1. In the operation interface, long press set for more than 3S to enter the parameter setting interface;
2. After entering the parameter setting interface, briefly press the set key to switch the parameters to be set (alarm temperature / delay start setting / temperature correction);
3. Use the up down key to modify the parameter value, and support short press / long press;
4. Press and hold set for more than 3S or for 6S without any key operation, exit the parameter setting interface and save the parameters;

How to turn on the high temperature alarm (off by default):
Enter the parameter setting interface, switch to the alarm parameter ala interface, and turn on or off the high temperature alarm function by short pressing the stop key; If the high temperature alarm function is off, ALA displays' ---- 'as a reminder;
How to turn on delayed start (off by default):
Enter the parameter setting interface, switch to the alarm parameter OPH interface, and turn on or off the high temperature alarm function by short pressing the stop key; If the high temperature alarm function is off, OPH displays' ---- 'as a reminder;
