3. Linji Gwida għall-Installazzjoni
Proper installation is crucial for the safe and effective operation of the STC-100A temperature controller. Ensure all electrical connections are made by a qualified professional if you are unsure.
3.1 Installazzjoni Fiżika
- Prepare an opening in your control panel or enclosure with dimensions matching the 'Installing Hole Size' (71mm L x 29mm W).
- Insert the STC-100A controller into the prepared opening.
- Secure the controller using the provided mounting clips or screws to ensure it is firmly in place.
- Connect the NTC temperature sensor probe to the designated terminals on the controller. Ensure the sensor is placed in the area where temperature measurement is required. The sensor wire length is 2 meters.
3.2 Wiring Elettriku
Twissija: Disconnect power before performing any wiring to prevent electric shock. All wiring should comply with local electrical codes.
- Connect the power supply (220VAC, 50/60Hz) to the designated power input terminals on the controller.
- Connect your heating or refrigerating load (e.g., compressor, heater) to the relay output terminals. The relay output capacity is 10A (0.5HP) at 220VAC.

4. Operazzjoni u Display Panel
The STC-100A features a two-digit LED display that shows the current temperature value and other operational information. Control is managed via three buttons located below the display.
Stampa 4.1: The operational display panel of the STC-100A. It features a digital LED display for temperature readings and three tactile buttons for navigation and setting parameters: an 'up' arrow, a 'down' arrow, and a 'set' button.
4.1 Funzjonijiet tal-buttuni
- Up Key (▲): Used to increase values or navigate upwards in menus.
- Down Key (▼): Used to decrease values or navigate downwards in menus.
- Ċavetta tas-Set (SET): Used to enter parameter setting mode, confirm selections, or save changes.
5. Istruzzjonijiet Operattivi
5.1 Power On/Off
The controller powers on automatically when connected to a suitable power supply. There is no dedicated power button.
5.2 Setting the Temperature Value
- Agħfas il- SET key once. The display will flash, indicating that the temperature setting value can be adjusted.
- Uża l- 'Il fuq (▲) or 'L isfel (▼) keys to adjust the desired temperature set point.
- Agħfas il- SET key again to confirm and save the new setting. The display will stop flashing and return to showing the current temperature.
5.3 Adjusting Advanced Parameters
To access and modify advanced parameters (e.g., difference value, delay protection, temperature calibration), refer to the detailed parameter list in the full manual. Typically, this involves pressing and holding the SET key for several seconds to enter the parameter menu, then using the 'Il fuq (▲) u 'L isfel (▼) keys to navigate and adjust values, and SET biex tikkonferma.
6. Manutenzjoni
Regular maintenance ensures the longevity and accuracy of your temperature controller.
- Tindif: Periodically wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.
- Kura tas-Sensor: Ensure the temperature sensor probe is clean and free from debris. Avoid bending or damaging the sensor wire. If the sensor appears damaged or provides inconsistent readings, it may need replacement.
- Kundizzjonijiet Ambjentali: Operate the controller within the specified operating temperature (0°C to +60°C) and relative humidity (+20% to +85%, non-condensing) to prevent damage.
7 Issolvi l-problemi
This section addresses common issues you might encounter with the STC-100A controller.
7.1 Sensor Error Alarm
- Sintomu: The display shows an error code (e.g., 'E1' or similar, as indicated by 'Alarm when sensor error' in main functions).
- Kawża Possibbli: The NTC sensor is disconnected, damaged, or faulty.
- Soluzzjoni: Check the sensor's connection to the controller. Ensure the wire is not cut or shorted. If the connection is secure and the error persists, replace the sensor. The delay time when sensor error is 1 minute before an alarm is triggered.
7.2 Qari tat-Temperatura Mhux Korrett
- Kawża Possibbli: Sensor misplacement, environmental interference, or calibration offset.
- Soluzzjoni: Ensure the sensor is correctly positioned to measure the desired temperature. Check for drafts or heat sources directly affecting the sensor. If necessary, use the temperature calibration function (refer to advanced parameters) to adjust the reading.
7.3 Il-Kontrollur Mhux Mixgħul
- Kawża Possibbli: L-ebda provvista tal-enerġija, volum mhux korretttage, jew wajers difettużi.
- Soluzzjoni: Verify that the 220VAC power supply is connected and active. Check all wiring connections for security and correctness. Ensure the voltage is within the specified range (220VAC +10% -15%).
