4. Інструкцыі па ўсталёўцы і падключэнні

Before proceeding with any wiring, ensure the power supply is completely turned off to prevent electric shock. Refer to the product label or the full-version manual for specific model details to ensure correct connection and EU compliance (IEC 60335-1:2020 standards for live part protection and terminal identification).

Кабельныя разводкі:

• Power Terminal (L/N): Connect to an AC 187~244V power supply. Ensure stable power input to avoid equipment malfunctions. The input power and current must be within the standard allowable deviation range. The power terminal must be clearly marked with voltagе параметры.
• Input Terminal (IN): Connect to the temperature sensor (NTC or other types). Ensure a tight connection for accurate signal transmission. Keep the sensor line away from the power line to avoid electromagnetic interference. For models supporting internal/external sensor switching, connect the sensor to the corresponding terminal.
• Output Terminal (OUT1/OUT2): Connect to the load (e.g., heater, cooler, compressor, solid-state relay). Match the load type with the controller's output mode, ensuring the load power does not exceed the controller's rated load. The output terminal must be clearly marked to avoid wrong connection.
• Ground Terminal (PE): Mandatory grounding is required for safe use and to prevent electrical hazards, complying with EU safety regulations. The grounding must meet EU LVD directive requirements and the terminal must be marked with the IEC 60417-5019 standard grounding symbol.

WARNING: Incorrect wiring (e.g., no grounding, wrong voltage, or wrong sensor connection) can cause electric shock, fire, or product damage, and may violate EU regulations. Always double-check wiring before powering on. Use standard wiring materials and ensure firm connections to prevent overheating.

The controller can be used at altitudes below 2500 meters for full-load operation. For altitudes above 2500 meters, the load power should not exceed 80% of the rated power.

1. Basic Temperature Setting: Press and hold the "S" (SET) key for 2 seconds to enter the target temperature setting mode. The display will flash. Use the "△" (up) or "▽" (down) key to adjust the target temperature to your required value. Hold the "△" or "▽" key for more than 1 second for quick adjustment. Press "S" again to confirm and exit, or press "M" to abandon the setting.
2. Карэкцыя тэмпературы: Enter the advanced parameter setting mode (long press "M" key for 5 seconds, enter password if set). Find the temperature correction parameter (H1 for general models, F19 for NF8830). Use the "△" or "▽" key to adjust the correction value (-9~9°C). Press "S" to confirm.
3. Налада блакіроўкі ад дзяцей: Long press the power key for 6 seconds to lock the keys. All short-press operations will be invalid after locking. The unlocking method is the same as locking.
4. Mode Switching (Cooling/Heating/Defrosting): Enter the advanced parameter setting mode. Set the cooling/heating mode (F29 for NF8830: COOL for cooling, HEAT for heating). For models with defrosting function, set the defrosting mode (electric/hot gas) and start mode through the parameter menu.
5. Time Setting (Manual Mode): In manual mode, press the "S" key to switch to the time display state. Long press the "S" key to enter the time adjustment mode. Adjust the hour and minute with the "△" or "▽" key, and press the "S" key to confirm.

5.3 Display & Alarm Introduction

• Звычайны рэжым: PV displays the current measured temperature, SV displays the target temperature. LED indicators show heating (H), cooling (C), defrosting, alarm (AL), and standby status.
• Рэжым налады: A flashing display indicates the parameter being set, including target temperature, temperature correction, timing time, defrosting parameters, and alarm parameters. Clear operation prompts help avoid misoperation.
• Рэжым сігналізацыі: When the temperature exceeds the set range, the sensor fails (open/short circuit), or the load is abnormal, the alarm indicator will light up. The display will show "00", "98", "OPE" (sensor open circuit), or "SHr" (sensor short circuit) for sensor faults. Alarm code "Axx" will be displayed alternately for other faults.

6. Тэхнічнае абслугоўванне
