Before powering the device, ensure the terminal connections match your specific model.

Power Terminals: Connect your AC power source to the designated L and N terminals (usually pins 1 and 2). Sensor Input:

Thermocouple: Connect positive to pin 8 and negative to pin 9. Pt100: Uses pins 8, 9, and 10 (three-wire compensation). Load Output:

Relay Model: Use the COM and NO (Normally Open) terminals to switch your heater or cooler.

SSR Model: Connect the DC output directly to the SSR input terminals. ⚙️ Programming and Parameter Settings

To enter the parameter menu, press and hold the SET key for 3 seconds. Use the ▲ and ▼ keys to adjust values. Basic Configuration

Set Point (SV): Tap the SET key once, adjust the value, and press SET again to save.

Hy (Hysteresis): Used in ON/OFF mode to prevent rapid switching.

P, I, D: These control the responsiveness of the PID algorithm. Advanced Parameters (Passcode: 0088)

Accessing the deeper menu allows for calibration and input changes: Inty: Change the input type (K, S, E, Pt100). Outy: Change the output method.

SC: Sensor calibration (offset adjustment if the reading is slightly off).

At: Auto-tuning. Set this to "1" to let the controller automatically calculate the best PID values for your system. 💡 Troubleshooting Common Issues

Display shows "EEEE": This usually indicates a sensor error. Check for a broken thermocouple or loose wiring. The XMTD-2201 is a robust, reliable PID controller

Temperature overshoots: The "P" (Proportional) band may be too narrow. Run the Auto-tuning (At) function to fix this.

No output: Check the "AL1" or "AL2" settings; an alarm might be overriding the main control loop. 📋 Safety Precautions Always disconnect power before wiring.

Ensure the sensor is rated for the maximum temperature of your application.

Keep high-voltage power lines separate from low-voltage sensor wires to avoid interference. If you'd like to dive deeper, let me know: Are you using a thermocouple or a Pt100? Are you driving a mechanical relay or an SSR?
