Units Description
Cooling staging options:
0− No cooling operation
1− Basic Tstat operation. Two cooling stages. Units with Economiz-
ers Y1=FreeCooling,
Y2=adds all mechanical stages.
2− Basic Tstat operation. Two cooling stages. Units with Economiz-
Option
ers Y1=Free Cooling, Y2= adds first stage of mechanical.
3− Basic Tstat operation. Three cooling stages. Y1 only = first
stage, Y2 only = second stage, Y1+Y2 = third stage. Units with
Economizers Y2 only adds first stage of mechanical, Y1+Y2
adds first and second stage of mechanical.
4− Discharge air control. Up to four stages.
