Modify the value and save it by pressing the return or set key.
While you should always check the diagram printed on the side of your specific unit, standard XT/XMT series wiring is usually: Terminals for AC 220V. Input terminals for TC (+/-) or RTD (three-wire).

The screen showed two numbers: the large top number (Process Value - PV) and the smaller bottom number (Set Value - SV).
Carefully connect your thermocouple (e.g., K-type) or RTD sensor. For thermocouples, pay close attention to the positive and negative polarities. Incorrect polarity will result in inaccurate temperature readings.
If you have a generic Chinese XTA-7000 (blue LCD, two rows), the manual is often wrong about the wiring. Always physically trace your thermocouple wires (Red = Negative for Type K, oddly). The manual always shows Red as positive – this is the #1 cause of "temperature goes down when heating." xta-7000 temperature controller manual

Press the key briefly once. The first digit on the SV display will flash. Use the Up or Down keys to change the number. Press the A/M key to move to the next digit field.
He corrected the wiring, ensuring the mechanical safety interlocks were properly connected to the controller’s alarm outputs. This is a common oversight; users often ignore the section, assuming the software handles safety, but the Xta-7000 relies on physical relay triggers for critical over-temperature protection.

Your primary interaction with the XTA-7000 is setting the SV (Set Value). Follow these steps from the manual:
The XTA-7000 is a popular, versatile PID temperature controller used in industrial settings (plastic injection molding, extruders, packaging machines) and high-end DIY projects (reflow ovens, 3D printer beds). Its manual is the gateway to unlocking its full potential. Here’s a detailed breakdown. Verdict (short) ✎ The screen showed two numbers:
