The CH535 chilled water temperature control is fulfilled through a
microprocessor based controller, monitoring water and refrigerant
temperature as long as refrigerant pressure.
The Micropocessor based controller is supplied factory mounted,
fully wired, configured and tested in factory. The controller ensures
compressor and fan sequence (load control), fault detection,
diagnostic and supervision.
Main features
- High and low refrigerant pressure protection
- Load
limit control to limit compressor loading on high return water
temperature
- Condenser fan sequencing with automatically
cycling in response to ambient condensing pressure
- Compressors anti-short cycle timer protection adjustable
- Automatic compressor lead-lag, to even out run hours and
compressors starts
- Phase reversal/single phasing
protection
- Low ambient lockout control with adjustable set
point
- Integrated RS485 serial port to allow BMS
connectivity
- Options for communication protocols: ModBus,
LonTalk and BACnet should be available
