SEQUENCE OF OPERATION - AIR HANDLING UNIT (AHU) - SINGLE ZONE VAV

EQUIPMENT

THE AIRSIDE SYSTEMS, AS IT APPLIES TO THE BUILDING AUTOMATION SYSTEM

(BAS), CONSISTS OF THE FOLLOWING EQUIPMENT:

AIR HANDLING UNIT(S), AHU-10-M-1, AHU-10-M-2, AHU-4-1-1, AHU-14-P-1, AHU-14-P-2,

AHU-14-P-3, AHU-14-P-4, AHU-12-P-1, AHU-12-P-2, AHU-9-1-1

RUN CONDITIONS

SCHEDULED:

THE UNIT MUST RUN BASED UPON AN OPERATOR ADJUSTABLE SCHEDULE.

SHUTDOWN:

UPON SHUTDOWN (EITHER MANUALLY, AUTOMATICALLY IN UNOCCUPIED, OR FROM

SAFETY FUNCTIONS), THE SUPPLY FAN MUST BE DE-ENERGIZED, THE OUTSIDE AIR

AND EXHAUST AIR DAMPERS MUST FULLY CLOSE, THE RETURN AIR DAMPER MUST

FULLY OPEN, AND THE DX COOLING AND ELECTRIC HEATING COILS MUST BE

DISABLED.

AHU OPTIMAL START:

THE UNIT MUST START PRIOR TO SCHEDULED OCCUPANCY BASED ON THE TIME

NECESSARY FOR THE ZONE TO REACH ITS OCCUPIED SETPOINT. THE START TIME

MUST AUTOMATICALLY ADJUST BASED ON CHANGES IN OUTSIDE AIR

TEMPERATURE AND ZONE TEMPERATURE. DURING THIS MODE, THE OUTSIDE AIR

DAMPER MUST BE FULLY CLOSED.

SUPPLY FAN

OCCUPIED:

THE SUPPLY FAN MUST RUN CONTINUOUSLY DURING OCCUPIED TIMES, UNLESS

SHUTDOWN ON SAFETIES. TO PREVENT SHORT CYCLING, THE SUPPLY FAN

UNOCCUPIED:

APPLY ± 3°F (ADJ) ALLOWABLE DRIFT FROM UNOCCUPIED HEATING AND COOLING

SETPOINTS AS DESCRIBED BELOW:

WHEN ZONE TEMPERATURE HAS RISEN ABOVE ITS UNOCCUPIED SPACE

TEMPERATURE COOLING SETPOINT, THE AHU MUST BEGIN STARTUP AND THE

OUTSIDE AIR AND EXHAUST AIR DAMPERS MUST REMAIN CLOSED. THE SUPPLY

FAN MUST RUN AT SUPPLY FAN MAXIMUM SPEED AND CHILLED WATER VALVE
