5.1. Күйгүзүү/өчүрүү
Once correctly wired and installed, apply power to the unit. The display will illuminate, showing the current temperature.
5.2. Температураны орнотуу
Press the "SET" button to enter the temperature setting mode. Use the "Up" and "Down" arrow buttons to adjust the desired temperature set point. Press "SET" again to confirm and exit.
5.3. Эритүүнү башкаруу
The controller manages defrost cycles automatically based on configured parameters, including compressor stop time and defrost final temperature. Specific programming steps for these parameters are typically detailed in the full product manual. Consult the manufacturer's comprehensive guide for advanced settings.
5.4. Password Lock Function
To prevent unauthorized changes, the controller includes a password lock function. Refer to the full product manual for instructions on how to activate, set, and disable the password.
6. Техникалык тейлөө
- Тазалоо: Regularly wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.

| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| Контроллер күйбөй жатат | Электр менен камсыздоо жок; туура эмес зымдар | Check power connections and ensure 220VAC supply. Verify wiring against diagram. |
| Температураны туура эмес окуу | Faulty sensor; sensor improperly placed | Check sensor connection and placement. Replace sensor if damaged. |
| Compressor not activating | Incorrect temperature settings; wiring issue; compressor fault | Verify set temperature and differential. Check compressor wiring. Test compressor independently if possible. |
8. Колдонуучунун кеңештери
- For optimal performance, ensure the temperature sensor is placed in a location that accurately reflects the temperature of the controlled environment, away from direct airflow or heat sources.
- When setting the temperature differential (hysteresis), consider the application to prevent rapid cycling of the compressor, which can reduce its lifespan.
- Always double-check wiring before applying power to avoid damage to the controller or connected equipment.
