together for approximately 10 seconds (often displays "F1" upon entry). Modify Parameters Up/Down arrows to navigate menu items (F1–F4) and press to view or adjust the value. Save & Exit : Press and hold
220VAC ± 10%, 50/60Hz (Optional 110VAC or 12VDC variants)
| Display | Meaning | Solution | |---------|---------|----------| | E1 | Sensor open circuit | Check sensor wiring or replace sensor | | E2 | Sensor short circuit | Replace NTC sensor | | EE | EEPROM error | Return to factory (reset not possible) | | AL-H | High temp alarm | Temperature > F6 setting | | AL-L | Low temp alarm | Temperature < F7 setting |
: If a sensor error occurs, the compressor switches to an automated backup cycle to protect your inventory. It runs for 15 minutes , shuts down for 45 minutes , and repeats this loop continuously until you repair the sensor path. Stc-600 Temperature Controller Manual Pdf
: The measured temperature has dropped below the controller's low limit. Check the sensor and wiring for an open circuit , and verify that the low alarm setpoint is configured properly.
Install the NTC probe, keeping it away from high-voltage wiring to avoid electromagnetic interference. 3. Wiring Diagram and Terminal Connections
220VAC ± 10%, 50/60Hz (Optional 110VAC available depending on model) together for approximately 10 seconds (often displays "F1"
The unit automatically stops the compressor and activates the defrost relay when the interval timer ( F6 ) expires. It keeps it on for the duration specified in F7 . 6. Troubleshooting and Error Codes
: Calibrates the device if the probe reading drifts over time. Adjust this offset value to match a certified reference thermometer. Diagnostic Codes & Safety Fail-Safes
Defrosting triggers automatically at the set intervals ( F04 ). It runs for 15 minutes , shuts down
Fan runs continuously throughout both cooling and defrost operations. Error Codes and Troubleshooting
The STC-600 is not a simple on/off thermostat; it is a sophisticated controller that manages multiple components of a commercial fridge or freezer simultaneously. Key features include:
: Confirms a physical failure within the sensor probe loop, such as a short circuit or severed wire.
