Fourtech Temperature Controller Manual Better Free Jun 2026
Connect the controller's internal relay in series with the external heating element contactor coil and the power source.
Once the "AT" light stops flashing, the controller has saved the optimal PID parameters and will maintain a highly stable temperature. 5. Troubleshooting Common Error Codes

What is this controller installed on?
The measured temperature exceeds the maximum safety limit of the selected sensor type.
Ensure the sensor (thermocouple or probe) is connected correctly (usually Terminals 1-2) and power is supplied (Terminals 7-8). Power On: The display will show the current temperature ( PVcap P cap V - Process Value). Setting the Target Temperature (SetPoint) Press the SET or SET/SET key once. The display will flash the setpoint value ( SVcap S cap V - Set Value). Use the Up/Down arrow keys to change the value. Press SET again to save. Accessing Parameter Settings (Advanced Setup) Hold the SET key for 3-5 seconds. Use the arrows to navigate through the parameters (e.g., AL1cap A cap L 1 Press SET to change the value, and hold SET again to exit. 4. Common FourTech Programming Parameters Connect the controller's internal relay in series with
Proper installation prevents equipment damage and ensures accurate temperature readings. Always disconnect the power supply before handling any electrical wiring. Terminal Configuration
You must tell the controller what kind of sensor is plugged in. Choosing the wrong input type will result in an "Err" message or wildly inaccurate readings. Auto-Tuning (AT):
The temperature sensor is disconnected, broken, or wired backward. Check the terminal 8, 9, and 10 connections. Troubleshooting Common Error Codes : Usually the Green
