Fourtech Temperature Controller Manual Portable -

Connect the positive and negative leads to the specified terminals (e.g., terminal 10 for positive).

This is the most common operation:

Use the and Down arrows to adjust the target temperature. Press SET again to save the new target value. Entering the Advanced Parameter Menu

Press the button once more to save the change. The SV display will stop flashing, and the controller will begin regulating power to match this value. Advanced Parameter Configuration fourtech temperature controller manual

Small LEDs (usually labeled OUT, ALM, or AT) that show if the heater is active, if an alarm is triggered, or if "Auto-Tuning" is in progress. 2. Basic Configuration and Wiring

The "AT" light on the faceplate will blink. The controller will now "learn" the thermal dynamics of your machine.

Searching for a is the first step toward precision temperature management. While having the physical or PDF manual is irreplaceable, this guide provides the foundational knowledge to navigate setup, programming, and troubleshooting. Connect the positive and negative leads to the

Connect the positive wire to Terminal 7 and the negative wire to Terminal 8.

. The controller will oscillate the temperature around the set point to calculate PID values automatically. www.fcanwell.cn Wiring Guidelines Fourtec: Home

Standard units often use 230V AC or 24V DC . Connect the phase and neutral to the designated power terminals (commonly pins 1-2 or 3-4 depending on the model). Sensor Input: Entering the Advanced Parameter Menu Press the button

If your system experiences temperature overshoot (getting too hot before dropping) or oscillates wildly around your target, you must calibrate the PID parameters using the built-in auto-tuning cycle.

Prevents thermal overshoot by predicting temperature trends. Hysteresis
