- 1 x BN-LINK Digital Temperature Controller T9
- 1 x Waterproof Temperature Probe (71 inch / 1.8m cord)
- 1 x foydalanuvchi qo'llanmasi
5. Sozlash
Follow these steps to set up your temperature controller:
- Connect the Temperature Probe: Insert the waterproof temperature probe into the designated port on the side of the controller. Ensure it is securely connected.
- Zondni joylashtiring: Place the temperature probe in the environment where you need to monitor and control the temperature. For liquids, ensure the probe tip is fully submerged. For air, position it away from direct heat or cold sources. The probe includes a suction cup for easy placement.
- Plug in Devices: Connect your heating device (e.g., heat mat, heater) to the outlet labeled 'HEATING' and your cooling device (e.g., fan, chiller) to the outlet labeled 'COOLING'.
- Yoqilgan: Plug the controller's power cord into a standard 125VAC 60Hz electrical outlet. The display will illuminate, showing the current temperature.

6. Foydalanish bo'yicha ko'rsatmalar
The controller allows you to set a target temperature and define temperature differentials for both heating and cooling.
6.1 Tugma funksiyalari
- KUCH: Jihozni yoqadi yoki o'chiradi.
- YUQORIGA (▲): Qiymatlarni oshiradi yoki opsiyalarni aylantiradi.
- DOWN (▼): Qiymatlarni kamaytiradi yoki opsiyalarni aylantiradi.
- CF/ST: Toggles between Celsius and Fahrenheit display. Press and hold to view status parameters.
- O'rnatish: Enters setting mode or confirms a selection.
- CLR: Clears current settings or exits setting mode without saving changes.
6.2 Setting Temperature Unit (°C/°F)
ni bosing CF/ST button once to switch between Celsius (°C) and Fahrenheit (°F).
6.3 Setting Target Temperature (SV)
- ni bosing SET button once. The 'SV' (Set Value) will flash on the display.
- dan foydalaning UP or PASTGA kerakli haroratni sozlash uchun tugmalar.
- bosing SET again to confirm and save the setting.
6.4 Advanced Settings (Differentials and Delay)
These settings allow you to customize how the heating and cooling cycles operate to prevent rapid cycling and maintain stable temperatures.
- ni bosing va ushlab turing SET button for 3 seconds to enter advanced settings. The display will show 'Hd' (Heating Differential).
- Foydalanish UP or PASTGA to adjust the value for the current parameter.
- bosing SET to move to the next parameter. The parameters are:
- Hd (Heating Differential): The temperature difference below the Set Value (SV) at which the heating device will turn on. For example, if SV is 70°F and Hd is 2°F, heating turns on at 68°F.
- Cd (Cooling Differential): The temperature difference above the Set Value (SV) at which the cooling device will turn on. For example, if SV is 70°F and Cd is 2°F, cooling turns on at 72°F.
- PT (Protection Time Delay): A delay (in minutes) before the heating or cooling output activates after the temperature crosses the threshold. This prevents short cycling of compressors or heaters.
- After adjusting all desired parameters, press SET to cycle through them until the display returns to normal operation, or press CLR o'zgarishlarni saqlamasdan chiqish.
7. Xizmat ko'rsatish
Proper maintenance ensures the longevity and accuracy of your BN-LINK T9 controller.
- Tozalash: Wipe the controller unit with a dry, soft cloth. Do not use abrasive cleaners or immerse the unit in water.
- Probni parvarish qilish: Regularly inspect the temperature probe for any signs of damage or corrosion. Clean the probe tip gently if residue builds up, especially in aquatic or humid environments.
- Saqlash: Ishlatilmayotganda, nazorat moslamasini to'g'ridan-to'g'ri quyosh nuri va haddan tashqari haroratdan uzoqda, salqin va quruq joyda saqlang.
8. Muammolarni bartaraf qilish; nosozliklarni TUZATISH
If you encounter issues with your BN-LINK T9 controller, refer to the following common problems and solutions:
| Muammo | Mumkin sabab | Yechim |
|---|---|---|
| Display is off or blank. | No power; Overload protection activated. | Check power connection. Reduce total load if an overload occurred. Press POWER button. |
| Haroratni o'qish noto'g'ri. | Probe improperly placed; Damaged probe. | Ensure probe is correctly positioned and clean. Replace probe if damaged. |
| Heating/Cooling device not turning on. | Incorrect temperature settings (SV, Hd, Cd); Device not plugged in; Device malfunction. | Verify SV, Hd, and Cd settings. Ensure devices are securely plugged into correct outlets. Test devices independently. Check PT setting for delay. |
| Controller cycles too frequently. | Differential settings (Hd, Cd) are too small. | Increase the Hd and Cd values to allow for a wider temperature fluctuation before activation. Adjust PT for longer delays. |
