Elias flipped to Chapter 5: PID Control Parameters. He needed to switch to PID (Proportional, Integral, Derivative) control. He held the "SET" key for three seconds to enter the deep parameter menu.
If the temperature fluctuates too much, use Auto-Tuning to let the controller find the best PID parameters. Enter the parameter menu (usually by long-pressing for ~3 seconds). Locate the parameter and change its value to AT indicator
Tip: If the PV does not reach SV after 10 minutes, check if the heating element is active (OUT1 LED) and that the output wiring is correct.
? If you need a copy of the manual, would like assistance selecting the right model, or need help troubleshooting a specific issue, I can help. Just let me know:
Ensure the ambient temperature is within the operating range, and avoid excessive humidity, vibration, or direct sunlight. 2.2 Electrical Wiring WARNING: Always isolate power before wiring the device. Power Supply: Connect the power lines ( 24VDC24 cap V cap D cap C depending on the model) to the designated terminals.

Before touching a single button, Elias recalled the first and most critical section of the : Safety and Installation.
Designed for DIN-rail or panel mounting, providing protection against industrial environments. 2. Installation Guide
If you see HHH on a PT100 sensor, unplug terminals 3,4,5. Use a multimeter to measure resistance between 4 and 5. A PT100 should read ~100 ohms at 0°C, ~138 ohms at 100°C. If infinite, the sensor is dead.
K, J, R, S, B, E, N, T (Thermocouples); Pt100, Cu50 (RTDs). Accuracy: ±0.5% of full scale.
