2. Důležité bezpečnostní informace

Please read and understand all safety instructions before installing or operating the STC-100A temperature controller. Failure to follow these instructions may result in electric shock, fire, or serious injury.

• Elektrické nebezpečí: This device operates on 220VAC. All wiring and installation should be performed by a qualified electrician or knowledgeable individual.
• Správné zapojení: Carefully distinguish between the relay interface, sensor wiring, and power supply wiring. Incorrect connections can damage the device or connected equipment.
• Wire Separation: Maintain a proper distance between the sensor wire and the power supply wire to prevent interference and ensure accurate readings.
• Ověřte svtage: Vždy zkontrolujte, zda napájecí objtage is correct (220VAC) before electrifying the unit.
• Podmínky prostředí: Do not expose the controller to excessive moisture, dust, or extreme temperatures outside its specified operating range (0℃-60℃, Relative Humidity: No more than 85% non-condensing).
• Odpojení: Před prováděním jakékoli údržby nebo změn zapojení odpojte napájení.

5. Instalace a zapojení

The STC-100A is designed for panel mounting. Ensure proper ventilation around the unit.

5.1 Montáž

• Cut a rectangular opening in your panel with dimensions of approximately 71mm x 29mm (2.8 x 1.1 inches).
• Vložte ovladač do otvoru zepředu.
• Secure the controller using the orange mounting clips on the sides. Push them inwards to lock the controller in place.

5.2 Pokyny pro zapojení

Refer to the wiring diagram on the back of the unit and Figure 5.2 below. Ensure all connections are secure and insulated.

1. Power Supply (220VAC): Connect your 220VAC power source to terminals 6 and 7. Ensure correct polarity if applicable, though AC typically does not have strict polarity for power input.
2. Teplotní senzor: Connect the temperature sensor cable to terminals 4 and 5. The sensor is non-polar, so connection order does not matter. Keep this wire separate from power wires.
3. Output Relay (10A/220VAC):
   • Terminal 1: Common (COM) for the relay output.
   • Terminal 2: Normally Closed (NC) contact.
   • Terminal 3: Normally Open (NO) contact.
   Connect your load (e.g., heater, cooler) to the appropriate relay contacts (COM and NO for heating/cooling, or COM and NC for specific applications) based on your control requirements.

6. Návod k obsluze

The STC-100A features a digital display and three buttons: Up (↑), Down (↓), and Set (SET).

Figure 6.1: Close-up of the control panel showing the display and buttons.

6.1 Nastavení teploty

1. Stiskněte tlačítko SOUBOR button once. The display will flash, indicating that you are in temperature setting mode.
2. Použijte ↑ (Nahoru a ↓ (Down) buttons to adjust the desired temperature set point.
3. Stiskněte tlačítko SOUBOR button again to confirm the setting and exit the setting mode. The display will return to showing the current temperature.

6.2 Understanding Control Modes (Refrigerating/Heating)

The STC-100A automatically switches between refrigerating and heating modes based on the set temperature and the current temperature, in conjunction with a configurable "return difference" (hysteresis). This ensures stable temperature control without rapid cycling.

Napřample, if set to 25°C with a 2°C return difference:

• Režim topení: If the current temperature drops below 23°C (25°C - 2°C), the heating output will activate. It will deactivate when the temperature reaches 25°C.
• Refrigerating Mode: If the current temperature rises above 27°C (25°C + 2°C), the refrigerating output will activate. It will deactivate when the temperature drops to 25°C.

Note: The specific parameter for setting the return difference (hysteresis) is typically accessed through a hidden menu or a combination of button presses. Refer to the detailed wiring diagram on the unit for advanced parameter settings if available.

6.3 Pokročilé funkce

• Korekce teploty: Allows for fine-tuning the temperature reading to match a known accurate thermometer. This compensates for any sensor inaccuracies.
• Alarm selhání senzoru: The unit will display an error code or alarm if the temperature sensor is disconnected or faulty.
• Control Output Delay: This feature prevents rapid cycling of the compressor or heating element, extending the lifespan of connected equipment. It introduces a delay before the output activates after a temperature change.

Detailed instructions for accessing and adjusting these advanced parameters are usually found in the full technical manual or by consulting the manufacturer's support resources.

7. Údržba

The Walfront STC-100A is designed for minimal maintenance. Follow these guidelines to ensure its longevity and proper operation:

• Čištění: Pravidelně otírejte displej a casing with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the unit.
• Větrání: Ensure that the ventilation slots on the sides of the unit are not obstructed to prevent overheating.
• Kontrola elektroinstalace: Annually inspect all wiring connections for tightness and signs of wear or corrosion.
• Péče o senzor: Keep the temperature sensor clean and free from debris. Ensure it is properly positioned in the area where temperature needs to be measured.
