SUPPL Y AIR SETPOINT
Setpoint determines where the economizer will modulate the OA
damper to maintain the supply air temperature.

OA DRY BU LB TEMPERATURE CHANGE OVER SETP OINT
Setpoint determines where the economizer will assume outdoor air
temperature is good for free cooling; e.g.: at 63_F(17_C), unit wil l
economize at 62_F (16.7_C) and below and not economize at 64_F
(17.8_C) and abov e . There is a 2_F(1.1_C) deadband.
