Xmtd-2201 Manual 'link' May 2026
XMTD-2201
The is an industrial digital temperature controller designed for precision monitoring and regulation in heating or cooling systems. It is part of the broader XMT series of instruments known for their high anti-interference performance and reliability. 🛠️ Technical Specifications
Before diving into buttons and wires, let's understand what the XMTD-2201 is. It is a digital PID (Proportional-Integral-Derivative) temperature controller with a dual four-digit LED display. It is known for its 96x96mm (or sometimes 72x72mm depending on the variant) DIN standard size, though the "2201" series typically features a bright red LED for process value (PV) and green for set value (SV). xmtd-2201 manual
Part 6: PID Auto-Tuning – The "Self-Learning" Feature
Troubleshooting
Specific terminals for connecting your thermocouple or PT100 sensor. PV display (red, 4 digits) – measured temperature
- PV display (red, 4 digits) – measured temperature
- SV display (green, 4 digits) – setpoint
- AT – auto-tune indicator
- OUT – output active (heating)
- AL1/AL2 – alarm status
- SET, ▲, ▼, R/S keys
If the heat goes way past your SV before settling, you may need to adjust the Hysteresis (P) Differential settings in the internal menu. If the heat goes way past your SV
If you've recently acquired an XMTD-2201 temperature controller, you likely know it is a workhorse of industrial and laboratory thermal management. However, the included "quick start" guide is often minimal, leaving users confused about wiring, alarm settings, or PID auto-tuning.
