4. Орнотуу жана зымдар

Proper wiring is crucial for the safe and correct operation of the STC-3000. Refer to the wiring diagram below.

Figure 4.1: Wiring diagram for the STC-3000. Terminals 1 and 2 are for power input (Powerinput). Terminals 3 and 4 are for the sensor (Sensor). Terminals 5 and 6 are for the load (Load).

Зымдарды орнотуу боюнча көрсөтмөлөр:

1. Кубат киргизүү (1 жана 2-терминалдар): Connect your 110-220V AC power supply to these terminals. Ensure the power is off before connecting.
2. Sensor Connection (Terminals 3 & 4): Connect the provided temperature sensor probe to these terminals. The sensor is non-polar, so connection order does not matter.
3. Load Output (Terminals 5 & 6): Connect the device you wish to control (e.g., heater, cooler) to these terminals. The controller acts as a switch for the load.

Note: This thermostat uses a single-pole relay. For 240V applications in regions like the USA where 240V is two 120V phases, only one phase of the load will be switched. Consider using an external dual-pole relay for complete power disconnection of the load if required by your application or local electrical codes.

5. Иштөө нускамалары

5.1 Негизги операция

• Күйгүзүү/өчүрүү: Press and hold the power button (usually located near the display) to turn the unit on or off.
• Дисплей: The large LED display shows the current measured temperature.
• Ачкычты кулпулоо/кулпусун ачуу: To unlock the buttons for setting parameters, press and hold the "SET" button for approximately 5 seconds until the display changes or unlocks. The lock icon will disappear.

5.2 Температура параметрлерин орнотуу

The STC-3000 allows you to set a target temperature and a hysteresis (difference) value to control the heating/cooling cycle.

1. Максаттуу температураны коюу:
   • "SET" баскычын бир жолу басыңыз. Учурдагы коюлган температура күйүп-өчүп турат.
   • Use the "Up" (▲) and "Down" (▼) arrows to adjust the desired target temperature.
   • Press "OK" or wait a few seconds for the setting to be saved.
2. Accessing Advanced Settings (P-codes):
   • Press and hold the "SET" button for approximately 3-5 seconds until "P0" appears on the display.
   • Use the "Up" (▲) and "Down" (▼) arrows to navigate through the P-codes (P0, P1, P2, etc.).
   • Press "SET" again to enter a specific P-code setting.
   • Use "Up" (▲) and "Down" (▼) to adjust the value.
   • Press "OK" or "SET" to confirm and exit the P-code setting.

Common P-Codes:

5.3 Switching between Celsius and Fahrenheit

Although the product label may indicate Fahrenheit, this model primarily displays in Celsius. However, some units may have a hidden function to switch. To attempt to switch between Celsius (C) and Fahrenheit (F) display modes:

• With the unit powered on and unlocked, press and hold the gray space between the "SET" and "RST" buttons (or the "OK" button on some variants) for approximately 5 seconds.
• The display should switch between "C" and "F" indicators if this function is available on your specific unit.

6. Техникалык тейлөө

The STC-3000 is designed for low maintenance. Follow these guidelines to ensure longevity:

• Тазалоо: Агрегатты жумшак, кургак чүпүрөк менен сүртүңүз. Абразивдүү тазалагычтарды же эриткичтерди колдонбоңуз.
• Сенсорго кам көрүү: Ensure the temperature sensor is clean and free from debris. Do not bend or damage the sensor cable excessively.
• Байланыштары: Мезгил-мезгили менен бардык зымдарды байланыштарды текшерип туруңуз, алар бекем жана коррозиядан таза.
• Курчап турган чөйрө: Operate the controller within its specified temperature and humidity ranges.

7. Кыйынчылыктарды

If you encounter issues with your STC-3000, refer to the following common problems and solutions:

7.1 Заводдук абалга кайтаруу

To restore the controller to its factory default settings:

• With the unit powered on, press and hold the "RST" button for approximately 5 seconds.
• The display will briefly show "888" or similar, indicating the reset is complete.
• After resetting, you may need to reconfigure your desired temperature and other parameters.
