<br />EXISTING SEQUENCE OF OPERATION:
<br />THE UNIT WILL OPERATE BASED ON REQUESTS TO RUN FROM THE VAV ZONES SERVED, BY SOFTWARE MANUAL OVERRIDE. FAN STATUS IS
<br />BASED ON A FEEDBACK STATUS SIGNAL FROM THE SUPPLY FAN VFD MONITORING ACTUAL DRIVE OUTPUT LEVEL THE MAKE-UP OUTSIDE AIR
<br />UNIT OAU-1, THE AHU DX COOLING STAGES, AND THE ASSOCIATED EXHAUST FANS WILL REMAIN OFF UNTIL THE SUPPLY FAN STATUS IS
<br />PROVEN.
<br />ON INITIAL START-UP, A WARM-UP/COOL-DOWN CYCLE IS INITIATED IF THE RETURN AIR TEMPERATURE IS BELOW/ABOVE AN ADJUSTABLE
<br />SETPOINT. THE WARM-UP/COOL-DOWN CYCLE WILL CONTINUE UNTIL THE SETPOINT IS SATISFIED, OR MAY BE DISABLED AT THE START OF
<br />SCHEDULED OCCUPANCY. DURING THIS CYCLE, THE MAKE-UP OUTSIDE AIR UNIT OAU-1 AND THE ASSOCIATED EXHAUST FANS WILL REMAIN
<br />OFF.
<br />ONCE REQUESTED TO RUN, THE SUPPLY FAN VFD IS ENABLED AND RAMPS UP TO A MINIMUM OUTPUT. ONCE THE SUPPLY FAN STATUS IS
<br />PROVEN, THE VFD OUTPUT WILL MODULATE AS REQUIRED TO MAINTAIN DUCT STATIC PRESSURE SETPOINT BASED ON A SENSOR LOCATED
<br />2/3 DOWN THE SUPPLY DUCT RUN. A HARD -WIRED SUPPLY AIR STATIC PRESSURE HIGH LIMIT SWITCH WILL SHUT DOWN THE SUPPLY FAN VFD
<br />IF THE PRESSURE EXCEEDS 4.0 IN.W.C.
<br />WHEN OPERATING IN THE OCCUPIED MODE, THE MAKEUP OUTSIDE AIR UNIT OAU-1 AND THE ASSOCIATED EXHAUST FANS WILL OPERATE
<br />CONTINUOUSLY. THE DX COOLING STAGES WILL SEQUENCE ON AS REQUIRED TO MAINTAIN SUPPLY AIR TEMPERATURE SETPOINT. THE
<br />SETPOINT CAN BE RESET BASED ON DEMAND FROM THE VAV ZONES SERVED.
