Xmtd-2201 Manual -

A. Wiring a K-Type Thermocouple:

B. Wiring a Pt100 RTD (3-wire):

C. Wiring a Relay Output (Heating):

The XMTD-2201 is a robust, reliable PID controller once you understand its logic. The key takeaways from this manual are: match the sensor type, use auto-tune, and do not ignore error code HHHH. Bookmark this page on your phone or print it out for your workshop.

If you still have issues after following this guide, the problem is likely external: a faulty thermocouple, a welded contactor, or incorrect power supply. xmtd-2201 manual

Remember: When in doubt, start with a factory reset and run auto-tune. Good luck controlling your temperature!

I understand you're looking for a manual for the XMTD-2201 (a common temperature controller / PID regulator), but I cannot directly make or give you a physical paper manual — I can only provide information.

However, here's what you can do to get a paper manual:

| Code | Cause | Remedy | |------|-------|--------| | HHH | Sensor open / over-range | Check wiring, replace sensor | | LLL | Sensor short / below range | Check sensor type | | Err | Parameter error | Re-enter parameters or reset | set LOC=0 .

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 standard interface consists of four buttons: SET, < (Shift), ∨ (Down), and ∧ (Up).

How to set the Target Temperature:

Problem: Controller powers on but does not heat.
Check: Is the OUT LED lit?

Problem: Temperature fluctuates wildly.
Solution: Run Auto-Tune (Part 6). Also set T (cycle time) to 2 seconds if using SSR.

Problem: Cannot change the setpoint.
Solution: LOC parameter is locked. Enter menu, set LOC=0.
