5. Иштөө нускамалары
5.1 Setting the Time of Day
- Rotate the dial clockwise until the current time of day aligns with the pointer on the timer face.
- Ensure the AM/PM indication is correct.
5.2 Setting Defrost Cycles
The timer allows for up to 48 defrost cycles per day. Defrost pins are typically colored differently (e.g., red for defrost, green for refrigeration).
- Insert the defrost pins into the desired time slots on the dial where defrost is required. Each pin represents a specific duration or start time.
- Adjust the defrost duration setting (if applicable to your model) to set the length of each defrost cycle (15 to 1425 minutes).
5.3 Индикатор жарыктары
- Жашыл жарык: Indicates the refrigeration cycle is active.
- Кызыл жарык: Эритүү цикли активдүү экенин көрсөтөт.
