| Problem | Possible Cause | Fix | |---------|----------------|-----| | No display | No power / wrong wiring | Check power input (1 & 2) | | Relay clicks but no output | Relay contacts worn | Use external contactor | | Temperature not accurate | Wrong sensor calibration | Adjust F3 calibration value | | Compressor cycles too fast | F4 delay too short | Increase F4 to 3–5 minutes |
To program your STC-600, press and hold the key for 3 seconds until the first parameter code ( F0 ) appears on the display. Use the ▲ or ▼ keys to navigate the menu. Press SET to view the value of a parameter, use the arrows to adjust it, and press SET again to temporarily save it. Press Rst to save all settings and exit. Parameter Menu Table Parameter Function Setting Range Default Factory Value F0 Temperature Set Value (Target Temp) Lower limit to Upper limit F1 Hysteresis / Temperature Differential 1°C to 15°C F2 Compressor Delay Protection Time 0 to 9 Minutes F3 Lower Temperature Limit (Min Target) -40°C to F0 F4 Upper Temperature Limit (Max Target) F0 to +50°C F5 Temperature Calibration / Offset -5°C to +5°C How It Works (Example Setup) If you want to keep a refrigerator at 4°C: Set F0 (Target) to 4 . Set F1 (Differential) to 2 .

The controller features several LED indicators for quick status checks:
Used to enter the parameter menu and confirm settings.
8A / 220VAC (Max inductive load is typically 2A or 250W) Sensor Type: NTC Sensor (Cable length typically 2 meters) Front Panel Waterproof Rating: IP65 STC-600 Wiring Diagram & Terminal Connections
: Cooling/Heating Control Output (Normally Open contact). Terminals 7 & 8 : Defrost Output Control (Model dependent). Terminals 9 & 10 : External Alarm Output or Fan Output. Front Panel Interface and Indicator Status Button Functions
A: According to the manual, press and hold the RST button for 10 seconds until the screen flashes 888 then goes blank. Release and unplug.
Supports both electric heating and natural defrosting methods.
The STC-600 temperature controller comes with several advanced features, including:
When the controller detects a fault, it will flash an error code on the display screen and trigger an audible buzzer alarm. Press any key to mute the buzzer.
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.
