Fourtech Temperature Controller: Manual ^hot^
Power Supply:
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:
- Set your desired Setpoint (SV).
- Press and hold the < button (or the v button depending on the specific model) for 3 seconds until the AT indicator starts blinking.
- The controller will now cycle the power to the heater (it will turn it on and off) to calculate the optimal PID values.
- The process usually takes 30 minutes to 2 hours depending on the thermal mass of your system.
- When the AT light turns off, tuning is complete.
- PV Display (Process Value) – Green/Red LED: Shows the actual current temperature.
- SV Display (Set Value) – Orange/Green LED: Shows your desired target temperature.
- SET Key – Used to enter and navigate the menu.
- Up/Down (Arrow) Keys – Adjust values and scroll through parameters.
- R/S Key (Run/Stop) – Some models use this to start or halt control output.
- A/M Key (Auto/Manual) – Toggles between automatic PID control and manual output percentage.
