6. Інструкція з експлуатації
The TC-321 allows you to set a target temperature and define temperature differentials for both heating and cooling modes. This ensures your environment stays within a desired range.
Setting Target Temperature and Differentials:

Image: Step-by-step visual guide on how to set the target temperature, cooling differential, and heating differential on the NICREW TC-321 display.
- Встановлення цільової температури:
- Натисніть і утримуйте НАБІР button for 3 seconds. The display will show the current target temperature setting.
- Використовуйте ▲ (вгору) або ▼ (down) buttons to adjust the target temperature to your desired value (e.g., 76°F).
- Прес НАБІР ще раз для підтвердження та переходу до наступного налаштування.
- Set Cooling Differential (COOL DIFF):
- After setting the target temperature, the display will show 'COOL DIFF'.
- Використовуйте ▲ or ▼ buttons to set the cooling differential (e.g., 4°F). This means the cooling device will activate when the temperature reaches Target Temp + Cool Diff (e.g., 76°F + 4°F = 80°F) and shut off when it returns to the Target Temp (76°F).
- Прес НАБІР знову для підтвердження.
- Set Heating Differential (HEAT DIFF):
- The display will now show 'HEAT DIFF'.
- Використовуйте ▲ or ▼ buttons to set the heating differential (e.g., 1°F). This means the heating device will activate when the temperature drops to Target Temp - Heat Diff (e.g., 76°F - 1°F = 75°F) and shut off when it returns to the Target Temp (76°F).
- Прес НАБІР one last time to save all settings and exit the programming mode.
The controller will now operate automatically to maintain the temperature within your set range.
Сигналізація температури:
The device includes a temperature alarm feature that activates if the temperature deviates significantly from your desired range, providing an alert for potential issues.
