 •  High effi ciency Eco

2

 rooftop units are optimized for 

HFC-410a refrigerant.  YORK provides the FIRST 
standard product offering that meets the latest 
ASHRAE 90.1 energy effi ciency requirements.

  •  Accurate ventilation control ensures that no more 

than the proper amount of ventilation air is utilized.  
This avoids the energy cost of conditioning excess 
outside air and simultaneously monitors all other 
unit functions for maximized energy effi ciency.

  •  Flexible design confi gurations simplify the design 

process and allows the Eco

2

 to be applied to virtually 

any building application.

  •  Accessibility through double-wall access doors, spa-

cious compartments and supportive fl oors improves 
serviceability.

•    Note that modulating heat is not offered with Elite 

controller option.

  •  Double-wall construction of the roof, fl oor,  doors, 

and walls prevents insulation fi bers from entering 
the conditioned air. The inner liner also facilitates 
periodic cleaning of the unit to prevent harmful build-
up of bacteria or contaminants.

  •  The rooftop unit control center uses microprocessor 

logic to analyze and optimize ventilation decisions and 
perform demand ventilation, and allow airfl ow compen-
sation to maintain the air quality at a healthy level.
