The STC-600 temperature controller requires proper wiring and installation to ensure safe and efficient operation. The manual provides a detailed wiring diagram, which shows the connections for power supply, sensor, and output devices.

The compressor shuts off immediately when the actual sensor temperature cools down to the Target Temp ( F0 ) . Example Scenario: Target Temp ( F0 ) = 4°C Hysteresis ( F1 ) = 2°C

Understanding the electrical and environmental limits of the STC-600 ensures safe operation and prevents hardware damage. 220VAC ± 10%, 50/60Hz Temperature Measuring Range: -40°C to +70°C Temperature Controlling Range: -40°C to +50°C Resolution: 1°C Accuracy: ±1°C Relay Output Capacity: 8A / 220VAC (for compressor) Defrost Options: Natural defrost or electrical defrost Sensor Type: NTC sensor (2-meter cable included) Safe Delay Time: 0 to 9 minutes adjustable 📐 Wiring and Installation

Q: What is the STC-600 temperature controller used for? A: The STC-600 temperature controller is used for precise temperature control in various industries, including food processing, pharmaceuticals, and HVAC.

Ultimate Guide to the STC-600 Temperature Controller: Manual, Setup, and Troubleshooting

Press and hold the Set key for more than 2 seconds until the screen flashes the current set value. Use the Up or Down arrows to adjust. Press Set or wait 10 seconds to save. 4. Parameter Settings and Configuration

Press the button to save the new value and return to the home screen. How Control Logic Works (Example: Cooling Mode)

The cooling system activates based on the target set point ( F01 ) and the hysteresis value ( F02 ).

⚠️ Do not exceed relay current rating. For inductive loads (motor, compressor), use an external contactor.

: Press "SET" for 3 seconds to access the user settings interface.

Ensure power is disconnected before wiring. Incorrect voltage application can damage the internal processor permanently.

: Protects the compressor by delaying its restart after reaching the set temperature (adjustable up to 15 minutes).

The temperature probe is damaged, disconnected, or short-circuited. Check sensor connections.

The STC-600 is a powerful and reliable controller for commercial refrigeration. To summarize, here are the key points to remember:

To enter the programming mode, press and hold the button for 3 seconds until the first parameter code appears on the screen. Parameter Menu Table Parameter Function Setting Range Default Value F1 Temperature Set Value (Target Temp) -40°C to +50°C F2 Hysteresis / Temperature Differential 1°C to 9°C F3 Compressor Startup Delay Time 0 to 9 minutes F4 Defrost Cycle / Interval Time 0 to 99 hours F5 Maximum Defrost Duration 1 to 99 minutes 20 minutes F6 Temperature Calibration / Offset -9°C to +9°C Step-by-Step Adjustment Guide Hold SET for 3 seconds until F1 flashes on the screen.
