Setup and Wiring

Proper wiring is crucial for the safe and correct operation of the STC-3028 controller. Refer to the wiring diagram on the back of the unit and the instructions below.

Wiring Diagram Interpretation

• പവർ സപ്ലൈ (110-220VAC): Connect the main power input to the designated terminals. Ensure the correct voltage (110-220VAC) is used as indicated on the unit.
• ഈർപ്പം സെൻസർ: Connect the integrated humidity sensor to its dedicated terminals.
• Relay Outputs (OUT): The unit has two relay outputs, typically for heating/cooling and humidifying/dehumidifying. Connect your controlled devices (e.g., heater, fan, humidifier) to these output terminals. Each output has a contact capacity of 10A/240VAC.
• പ്രധാന കുറിപ്പ്: Strictly distinguish the connections for the sensor, power supply, and relay outputs. Maintain a proper distance between the sensor down-lead and power wires to prevent interference.

പ്രവർത്തന നിർദ്ദേശങ്ങൾ

Setting Startup Temperature (Humidity)

1. Press the "up" button once to display the current starting temperature or humidity setting.
2. Long press the "up" button for approximately 3 seconds until the displayed value flashes.
3. Use the "up" and "down" arrow keys to adjust the desired starting temperature or humidity value.
4. The setting will automatically save after a few seconds of inactivity or by pressing another button.

Setting Stop Temperature (Humidity)

1. Press the "down" button once to display the current stop temperature or humidity setting.
2. Long press the "down" button for approximately 3 seconds until the displayed value flashes.
3. Use the "up" and "down" arrow keys to adjust the desired stop temperature or humidity value.
4. The setting will automatically save after a few seconds of inactivity or by pressing another button.

Temperature and Humidity Correction (Calibration)

• To enter the calibration mode, press the "up" and "down" buttons simultaneously.
• Follow the on-screen prompts to adjust the temperature and humidity readings if they deviate from a known accurate reference.

The controller allows for separate heating/cooling and humidifying/dehumidifying functions, providing robust protection against violent environmental changes.

മെയിൻ്റനൻസ്

• വൃത്തിയാക്കൽ: Regularly wipe the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• സെൻസർ പരിചരണം: Keep the integrated sensor clean and free from dust or debris to ensure accurate readings. Avoid exposing the sensor to extreme moisture or physical damage.
• വെൻ്റിലേഷൻ: Ensure the controller's vents are not obstructed to allow for proper heat dissipation.
• കണക്ഷനുകൾ: എല്ലാ വയറിംഗ് കണക്ഷനുകളും സുരക്ഷിതമാണെന്നും തുരുമ്പെടുക്കലിൽ നിന്ന് മുക്തമാണെന്നും ഉറപ്പാക്കാൻ ഇടയ്ക്കിടെ പരിശോധിക്കുക.

പൊതുവായ പ്രശ്നങ്ങളും പരിഹാരങ്ങളും

• ഡിസ്പ്ലേ പ്രകാശിക്കുന്നില്ല: Check the power supply connection. Ensure the input voltage നിർദ്ദിഷ്ട പരിധിക്കുള്ളിലാണ് (110-220V AC).
• കൃത്യമല്ലാത്ത വായനകൾ: Verify the sensor is clean and properly connected. Perform a temperature and humidity calibration if necessary. Ensure the sensor is not placed in an area with extreme air currents or direct heat/cold sources that do not represent the overall environment.
• Controller Not Activating Devices: Check the relay output connections to your heating/cooling or humidifying/dehumidifying devices. Ensure the set parameters (startup/stop temperatures/humidity) are configured correctly for your desired operation. Verify the devices themselves are functional.
• Humidity Reading Stuck at 100%: This could indicate a sensor issue or extreme environmental conditions. Ensure the sensor is dry and not exposed to condensation. If the issue persists, the sensor may need replacement.
