BELOW THE RETURN AIR ENTHALPY BUT ABOVE ECONOMIZING SETPOINT.

A. WHEN BTU CALCULATION FOR OUTDOOR AIR CONDITIONS EXCEEDS 28 BTUH/LB

(ADJ.), ECONOMIZER SHALL BE DISABLED.

9. MINIMUM OUTDOOR AIR CONTROL - SYSTEM CONTROLLER SHALL MODULATE MIXED AIR

DAMPERS TO MAINTAIN MINIMUM CFM SETPOINT MEASURED BY AN OUTDOOR AIR FLOW

MEASURING STATION. LIMIT THE CLOSING OF THE OUTDOOR AIR DAMPER TO PROVIDE

ABSOLUTE MINIMUM OUTDOOR AIR FLOW.

A. OUTDOOR – RELIEF/EXHAUST – RETURN MODULATING WITH ONE SIGNAL FROM

CONTROLLER.

B. REFER TO UNIT SCHEDULE FOR THE ABSOLUTE MINIMUM OUTDOOR AIRFLOW CFM

SETPOINT.

10. FILTER MONITORING - SYSTEM CONTROLLER SHALL MONITOR AND ALARM FILTER
