Page 4: Features And Benefi Ts
Features and Benefi ts AIRFLOW CONFIGURATIONS Variable-Air-Volume – Eco units are available for single-zone variable-air-volume (VAV) applications. Supply fans are controlled to the supply duct static pressure setpoint, which can be reset via a BAS, or through an analog voltage input on the unit controller for optimized duct static pressure control. -

COMMUNICATIONS BACnet MSTP (RS-485) Communications – This communication is available via optional Modlinc Gate- way. Communications to the unit are through a twisted pair, and the wire terminations are on the primary unit control board. Modbus RTU Communications – This communication is standard on every Eco unit and can be used in lieu of the BACnet communications (only one can be used... -

CONDENSER FEATURES AND OPTIONS Scroll Compressors – Reliable, effi cient, trouble-free operation is the true measure of a packaged rooftop’s value. That’s why YORK Eco Packaged Rooftop Air Conditioners use established scroll compressor technology to deliver dependable, economical per- formance in a wide range of applications. - Page 7 ACCESSORIES Filter Switch – An optional dirty fi lter alarm can be pro- vided that will provide an alarm when the fi lters require cleaning. Magnahelic Filter Pressure Gauge – On units equipped with downstream fi ltration, a magnahelic fi lter gauge is included and visible on the exterior of the unit.

Exhaust/relief fans – In this application, a powered exhaust fan may be suitable, however careful consid- eration of the fan type is necessary. YORK offers a centrifugal powered exhaust fan to perform this function. Some manufacturers use a propeller exhaust fan, which cannot handle the static pressure requirements. -
Page 11: Acoustical Considerations
In the non-modulating exhaust system, the exhaust air- fl ow is constant whenever the exhaust fan is operating. This type of control should only be used to either assist a smoke purge system or when a system requires a constant volume of exhaust airfl ow.

Page 17: Altitude And Temperature Corrections
Altitude and Temperature Corrections The information below should be used to assist in application of product when being applied at altitudes at or exceeding 1000 feet above sea level. The airfl ow rates listed in the standard blower perfor- mance tables are based on standard air at sea level. As the altitude or temperature increases, the density of air decreases. -
