  • Page 3: Introduction

    Introduction York YCWS Water Cooled Screw Chillers YORK YCWS Water-Cooled models provide chilled water for all air conditioning applications that use central station air handling or terminal units. They are completely self-contained and are designed for indoor (new or retrofit) installation. Each unit includes accessible semi-hermetic screw compressors, a liquid cooler, water cooled condenser, and a user-friendly, diagnostic Microcomputer Control Center all mounted on a rugged steel base.

  • Page 4: Specifications

    The unit will be pressure-tested, evacuated, and charged with Refrigerant-22, and York ‘L’ (POE) synthetic oil. There will be an operational test, with water flowing through the cooler, to check that each control device operates correctly.
  • Page 5 (EPROM) to eliminate chiller failure due to AC power failure. The microprocessor can be directly connected to a YORK ISN Building Automation System via the standard on- board RS485 communications port. This option also pro- vides open system compatibility with other communica- tions networks.
  • Page 6 Liq- uid temperature setpoint reset signal from YORK ISN or building automation system (by others) via: • Pulse width modulated (PWM) input for up to 40°F (22°C) total reset as standard.

  • Page 7: Accessories & Options

    • Printed circuit board to accept 4 to 20 milliamp, 0 to 10 VDC, or dry contact closure input from the BAS. • A YORK ISN Building Automation System can provide a Pulse Width Modulated (PWM) signal direct to the standard control panel via the standard onboard RS485 port.
