Description
- System: XC660D designed for managing compressors and fans in a condensing system like a pack.
- Compressor Compatibility: Compatible with scroll or Stream compressors, simple or multistage. Can manage up to 2 suction circuits with a common condenser.
- Control Mechanism: Uses a neutral zone based on pressure or temperature sensed in LP suction (compressors) and HP (condenser) circuits. Special algorithm balances compressor run hours for uniform workload distribution.
- Pressure Conversion: Controllers convert both LP and HP pressures and display them as temperatures.
- Front Panel Display: Provides comprehensive system status info including suction and condenser pressure (temperatures), load status, alarms, and maintenance conditions.
- Alarm System: Each load has its own alarm input capable of stopping it when triggered. Additionally, two inputs for low and high pressure switches ensure system safety; activation halts the system.
- Programming: Controller can be easily programmed at power on via the HOT KEY.
- Connectivity: Controller can connect to the X-WEB controlling and monitoring system through RS485 serial output using the ModBus RTU protocol.
