Overview and Features

1. Integrated Chiller Control Functions
- Provides comprehensive chiller control within a single device, eliminating the need for additional configuration.
- Built-in control functions include EEV control, compressor control, outdoor fan control, oil circulation pump control, liquid injection control, hot gas control, heater control, oil, temperature control, and pressure equalization control.

2. Precision Control
- Achieves precise oil temperature regulation with 0.1°C accuracy.
- Integrated control of EEV, outdoor fan, and compressor ensures stable and accurate operation.

3. Enhanced Protection Features
- Provides enhanced high pressure, low pressure, low compression ratio, oil temperature, discharge temperature, compressor overcurrent, inverter overvoltage, inverter temperaure protection.

4. Built-in Sensorless Inverter for Compressor
- Implements latest sensorless technology for stable operation even at low speeds.
- Optimized current control ensures high energy efficiency.

5. Adaptive Protection Function
- Enhances protection beyond standard safety features to prevent unexpected shutdowns due to environmental conditions.
- Adjusts operating speed to compensate for rising ambient temperatures.
- Detects changes in compressor and fan loads and dynamically optimizes performance.

6. Replacement for Old Japanese Models
- Supports standard 3phase 220V power, making it a compatible replacement for older Japanese chiller models.
