The XMTD-2201 is a digital temperature controller widely used in industrial heating and cooling systems. This guide provides a comprehensive breakdown of its features, wiring, and programming. 🛠️ Key Specifications Input Type: K-type thermocouple (standard) or RTD (Pt100). Control Mode: Intelligent PID or ON/OFF control. Output: Relay contact (5A) or SSR drive signal. Display: Dual LED (Process Value and Set Value). Power Supply: 85–264V AC. 🔌 Wiring Diagram & Installation
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.
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?

The XMTD-2201 is a microprocessor-based digital temperature controller renowned for its reliability, cost-effectiveness, and ease of use. It is widely utilized in industrial automation, laboratory equipment, and environmental control systems. This article serves as a practical manual, covering specifications, wiring, programming, and troubleshooting.
Scenario: You want to control a 220V Heater.
⚠️ SAFETY WARNING: Always disconnect power before wiring. If you are controlling high-power heaters, do not pass the high current directly through the controller terminals (Terminals 3 & 4 usually max out at 3 Amps). Use the controller to switch a larger external Contactor or Solid State Relay (SSR) instead.
The XMTD-2201 has two independent alarms. They can be set as:
To set Alarm 1 as a high-temperature safety cut-off at 250°C:
AL-1. Set to 250.HY-1. Set to 5 (alarm turns off when temp drops to 245°C).Problem: The display shows "HHHH" or "OPEN"
Problem: The display shows "LLLL"
Problem: The temperature keeps rising past the setpoint (Overshoot).
Problem: The output indicator is ON, but the heater is not working.
This is where most users get lost. The XMTD-2201 contains a hidden secondary menu for configuring input type, PID values, and alarms.

. While these devices are incredibly durable, their menus can feel a bit cryptic if you don’t have the manual handy. Here is a streamlined guide to getting your up and running. 1. Understanding the Faceplate
Before diving into settings, let's look at what the display is telling you: PV (Process Value): The current temperature measured by your sensor. SV (Set Value): The target temperature you want to reach. Indicators:
Look for the "OUT" light; if it’s on, the controller is sending power to your heater. 2. Setting Your Target Temperature
This is the most common task. You don't need to enter a deep menu for this: button once briefly. The SV display should start flashing. Down (▼) arrows to reach your desired temperature.

Terminals for your AC power (typically 220V or 110V depending on your specific model). Specific terminals for your K-type thermocouple RTD (PT100)
. Ensure the polarity (+/-) is correct, or the temperature will read incorrectly (often showing "EEEE" or moving backward). This model usually features a Relay output SSR (Solid State Relay) drive 4. Troubleshooting Common Issues Display shows "EEEE" or "LLLL":
This usually indicates a sensor error. Check that your thermocouple is wired securely to the correct terminals. Temperature "Overshooting":
If the heat goes way past your SV before settling, you may need to adjust the Hysteresis (P) Differential settings in the internal menu.
Check the "OUT" indicator. If the light is on but there's no heat, the issue is likely with your external heater or a blown fuse in your circuit. 5. Entering the Parameter Menu
To change advanced settings (like sensor type or alarm limits): Press and hold for about 3-5 seconds. The PV window will show a parameter code (like Use the arrows to change values and to cycle to the next parameter. To exit, hold again or wait for it to time out. Need the full wiring diagram?
