ROOFTOP UNIT SEQUENCE OF OPERATIONS

A. ENABLE ROOFTOP UNITS TO RUN SUPPLY FANS CONTINUOUSLY. GENERATE

ALARM IF ROOFTOP UNIT STATUS DOES NOT MATCH COMMAND. MODULATE

FAN SPEED TO MAINTAIN DISCHARGE AIR PRESSURE AT SETPOINT.

B. POLL VAV BOXES CONNECTED TO EACH ROOFTOP UNIT. IF MAJORITY OF VAV

BOXES NEED HEATING, ENABLE HEATING MODE ON ROOFTOP UNIT. IF

MAJORITY OF VAV BOXES NEED COOLING, ENABLE COOLING MODE OF

ROOFTOP UNIT. IF VAV BOXES ARE SATISFIED OR SPLIT EVENLY BETWEEN

HEATING AND COOLING, ROOFTOP UNIT IN DEADBAND MODE SHALL PROVIDE

DISCHARGE AIR BETWEEN 68-72F.

C. IF IN HEATING MODE, RESET DISCHARGE AIR TEMPERATURE SETPOINT

FROM 72F TO 100F BASED ON AVERAGE HEATING DEMAND FROM

CONNECTED VAV BOXES.

D. IF IN COOLING MODE, RESET DISCHARGE AIR TEMPERATURE SETPOINT

FROM 70F TO 55F BASED ON AVERAGE COOLING DEMAND FROM

CONNECTED VAV BOXES.

E. MAP ALARM POINTS TO BUILDING AUTOMATION SYSTEM GRAPHICS PAGES.

F. SET MINIMUM AIRFLOWS ON VAV BOXES TO MAINTAIN MINIMUM AIRFLOWS

REQUIRED BY ROOFTOP UNITS.

G. RESET ROOFTOP UNIT DISCHARGE AIR PRESSURE SETPOINT TO MAINTAIN

THE MAXIMUM VAV BOX DAMPER AT 95%.

PROVIDE 1/2" TEST TEE

6" DIRT LEG

PAINT ALL GAS PIPE EXPOSED TO

WEATHER WITH GRAY EPOXY PAINT.

ALL PIPE, FITTINGS, ETC. DOWNSTREAM OF SHUT OFF VALVE SHALL BE NEW.

PROVIDE NEW SHUTOFF VALVE

CLOSE TO ROOF PENETRATION. IF

THERE IS AN EXISTING VALVE IN THIS

LOCATION, IT CAN REMAIN IF VERIFIED
