3.1 SEQUENCE OF OPERATION

SEQUENCE OF OPERATIONS FOR HVAC CONTROLS

AHU SEQUENCE

GENERAL - THE SCHEDULING PROGRAM AUTOMATICALLY INDEXES THE VAV BOXES AND AIR HANDLING UNIT AHU TO EITHER THE “OCCUPIED” OR “UNOCCUPIED” MODE. WHEN THE AHU IS INDEXED TO THE “OCCUPIED” MODE, IT OPERATES CONTINUOUSLY AS DESCRIBED BELOW AND THE ZONE THERMOSTATS ON ITS VAV BOXES MAINTAIN THEIR “OCCUPIED” HEATING AND COOLING SETPOINTS. WHEN THE AHU IS INDEXED TO THE “UNOCCUPIED” MODE, THE AHU SHUTS DOWN UNLESS ZONE TEMPERATURE FOR ANY ASSOCIATED VAV EXCEEDS ITS “UNOCCUPIED” HEATING SETPOINT OF 60 DEGREES (ADJUSTABLE) OR ITS “UNOCCUPIED” COOLING SETPOINT OF 80 DEGREES (ADJUSTABLE). WHEN THIS OCCURS, THE AHU STARTS AND RUNS UNTIL ALL ZONES ARE SATISFIED. DURING THE “UNOCCUPIED” MODE, AN OVERRIDE PUSHBUTTON ON EACH THERMOSTAT ALLOWS THAT VAV BOX AND ITS AHU TO BE RETURNED TO NORMAL “OCCUPIED” OPERATION FOR A PRESET PERIOD OF 120 MINUTES (ADJUSTABLE). THE “UNOCCUPIED” HEATING AND COOLING SETPOINTS, THE PUSHBUTTON OVERRIDE TIME, AND THE “OCCUPIED” SETPOINT ADJUSTMENT LIMITS ON THE VAV THERMOSTATS ADJUSTABLE ON THE GRAPHICS INTERFACE WITHIN THE BAS.

FAN CONTROL AND SAFTIES - ON AHU STARTUP, THE SUPPLY AND EXHAUST FANS START THROUGH THE VFD AT MINIMUM SPEED AND RAMP-UP AS REQUIRED TO MAINTAIN SUPPLY DUCT PRESSURE SETPOINT. THE EXHAUST FAN SHALL OPERATE TO MAINTAIN AIRFLOW CALCULATED UTILIZING AN OFFSET AIRFLOW VALUE. THIS VALUE SHALL BE CALCULATED BY THE TEST AND BALANCE CONTRACTOR AT THE OCCURANCE OF THE INITIAL TEST AND BALANCE. THE VALUE FOR THE OFFSET AIRFLOW SHALL BE DETERMINED USING THE EXHAUST VALUE OF THE PORTION OF THE BUILDING SERVED BY THE UNIT AS A STARTING POINT AND INCREASING THE AIRFLOW VALUE (THERE-BY REDUCING THE RETURN AIRFLOW) UNTIL THE BUILDING OPERATES AT A SATISFACTORY POSITIVE PRESSURE. ONCE THE VALUE IS DETERMINED, THEN THE EXHAUST FAN AIRFLOW SHALL BE MAINTAINED AT THIS OFFSET AIRFLOW VALUE WITH RESPECT TO THE SUPPLY AIRFLOW THROUGHOUT THE OPERATING RANGE. CURRENT SWITCHES SHALL INPUT THE STATUS OF EACH FAN TO CONTROLLER AHU FOR READOUT. AN ALARM IS GENERATED IF A FAN FAILS TO OPERATE WHEN COMMANDED TO RUN. WHEN THE SUPPLY FAN IS OPERATING A CURRENT SWITCH ACTIVATES AND THE AHU CONTROLS OPERATE AS DESCRIBED BELOW. WHEN THE SUPPLY FAN SHUTS DOWN, ALL VALVES AND DAMPERS GO TO THEIR NORMAL POSITIONS WITH THE OUTSIDE DAMPERS CLOSED, THE RETURN DAMPER OPEN, THE STEAM VALVE OPEN, AND THE CHILLED WATER VALVE CLOSED. ALSO, THE EXHAUST FAN SHUTS DOWN AND THE RETURN DAMPER CLOSES.

THE AHU SHALL SHUTDOWN AND AN ALARM SHALL BE COMMUNICATED TO THE CONTROLLER IF ANY OF THE FOLLOWING SAFETY

CONTROLS ACTIVATE:

1) A MANUALLY RESET HIGH PRESSURE SWITCH ON THE SUPPLY FAN TRIPS

2) A MANUALLY RESET FREEZESTAT AT THE COOLING COIL INLET TRIPS

3) A FIRE ALARM SYSTEM RELAY ACTIVATES

A DIFFERENTIAL PRESSURE SWITCH SHALL GENERATE A MAINTENANCE ALARM IF PRESSURE DROP ACROSS THE FILTERS EXCEEDS

THE SETPOINT OF THE SWITCH.

SUPPLY DUCT PRESSURE CONTROL - A PRESSURE TRANSMITTER SHALL BE LOCATED IN THE SUPPLY DUCT AND CONTROLLER AHU MODULATE THE SPEED OF THE SUPPLY FAN AS REQUIRED TO MAINTAIN THE SUPPLY AIR STATIC PRESSURE SETPOINT. UPON A DECREASE IN DUCT PRESSURE BELOW SETPOINT, THE SPEED OF THE SUPPLY FAN SHALL BE INCREASED. THE SETPOINT IS OPTIMIZED ONCE EVERY 15 MINUTES BY A CALCULATION IN THE CONTROLLER WHICH MONITORS THE POSITION OF THE FLOW DAMPERS ON ANY ASSOCIATED VAV BOX WHICH IS OPERATING IN THE “OCCUPIED” OR “UNOCCUPIED” MODE. WHEN THE CALCULATION RUNS AND ANY DAMPER IS >90% OPEN, THE STATIC PRESSURE SETPOINT IS INCREMENTED UPWARD BY +0.10” W.C., UNLESS THE FAN IS ALREADY RUNNING AT ITS MAXIMUM SPEED. WHEN THE CALCULATION RUNS AND ALL DAMPERS ARE <80% OPEN, THE STATIC PRESSURE SETPOINT IS DECREMENTED DOWNWARD BY -0.10” W.C., UNLESS THE FAN IS ALREADY RUNNING AT ITS MINIMUM SPEED. THE RESET OF THE SETPOINT IS LIMITED IN SOFTWARE TO 0.8” W.C. MINIMUM AND 3.0” W.C. MAXIMUM (ADJUSTABLE). ON STARTUP OF THE SUPPLY FAN, THE SETPOINT IS INITIALLY SET TO THE MAXIMUM LIMIT AND THEN THE CALCULATION BEGINS TO RESET THE SETPOINT TO THE OPTIMUM VALUE. THE MAXIMUM SETPOINT LIMIT, THE MINIMUM SETPOINT LIMIT, THE INCREMENT & DECREMENT AMOUNT, THE UPPER & LOWER DAMPER POSITIONS TO INCREASE OR DECREASE THE SETPOINT, AND THE FREQUENCY OF THE CALCULATION SHALL EACH BE ADJUSTABLE ON A DETAIL PAGE OF THE AHU GRAPHIC WITHIN THE BAS. THIS GRAPHIC PAGE SHALL ALSO DISPLAY THE ACTUAL STATIC PRESSURE, THE CALCULATED SETPOINT, AND THE CURRENT POSITION OF EACH VAV BOX DAMPER. IN ADDITION, THIS GRAPHIC SHALL “HIGHLIGHT” THE TERMINAL BOX BEING USED TO INCREMENT OR DECREMENT THE SETPOINT. AN ENABLE/DISABLE POINT TO INCLUDE OR EXCLUDE EACH BOX IN THE CALCULATION IS PROVIDED. A MASTER ENABLE/DISABLE POINT SHALL BE PROVIDED FOR THE OPTIMIZATION CALCULATION. IF IT

IS DISABLED, THE SETPOINT GOES TO THE MAXIMUM SETPOINT VALUE.

OA FLOW MODE CONTROL - AN OUTSIDE AIR FLOW STATION AND A SUPPLY AIR FLOW STATION ON THE UNIT INPUT FLOW SIGNALS TO THE UNIT CONTROLLER FOR READOUT AND CONTROL. THE AIR HANDLING UNIT TO DETERMINE IF THE UNIT SHOULD OPERATE

ON THE “MIN OA” MODE OR THE “ECONOMIZER” MODE AS DESCRIBED BELOW.

WHEN THE AHU FIRST STARTS, IT INITIALLY OPERATES IN THE "NORMAL" MODE. IN THIS MODE THE MINIMUM OUTSIDE AIR DAMPER IS OPEN AND THE EXHAUST FAN IS SET TO ITS MINIMUM FLOW. EITHER THE HEATING VALVE OR CHILLED WATER VALVE SHALL

MODULATE FOR TEMPERATURE CONTROL.

WHEN THE AHU REQUIRES MORE OUTSIDE AIR THAN ITS MINIMUM OUTSIDE AIR FLOW TO MAINTAIN ITS SUPPLY AIR TEMPERATURE CONDITIONS BASED ON COMPARISON OF OUTSIDE AIR AND RETURN AIR ENTHALPY (AS DESCRIBED BELOW) THEN "ECONOMIZER" MODE SHALL BE INITIATED IN THIS MODE THE POWERED EXHAUST FAN SHALL INCREASE TO A MAX FLOW AND THE ECONOMIZER

OUTSIDE AIR DAMPER SHALL MODULATE OPEN.

WHEN OUTSIDE AIR ENTHALPY EXCEEDS RETURN AIR ENTHALPY, THE AIR HANDLING UNIT SHALL BE SWITCHED BACH TO THE "NORMAL" MODE. THE ECONOMIZER OUTSIDE AIR DAMPER SHALL MODULATE CLOSED AND THE POWERED EXHAUST FAN SHALL BE REDUCE TO A MINIMUM SPEED. WHEN OUTSIDE AIR ENTHALPY AGAIN FALLS BELOW RETURN AIR ENTHALPY, THE UNIT SWITCHES

BACK TO THE "ECONOMIZER" MODE AS DESCRIBED ABOVE.

SPACE PRESSURE CONTROL - SPACE PRESSURE CONTROL SHALL BE ACCOMPLISHED THROUGH AN AIRLOW TRACKING UTILIZING

AN OFFSET AIRFLOW FOR EXHAUST FAN CONTROL. THIS SEQUENCE IS DESCRIBED ABOVE.

“OCCUPIED” TEMPERATURE CONTROL - DURING THE “OCCUPIED” MODE, SENSOR IN SUPPLY AIR AND CONTROLLER AHU MODULATE HEATING VALVE, AND THE CHILLED WATER VALVE IN SEQUENCE AS REQUIRED TO MAINTAIN THE SUPPLY AIR SETPOINT.

THE INITIAL SETPOINT IS 55 DEGREES; HOWEVER, THE CONTROLLER GRADUALLY RESETS THE SUPPLY SETPOINT FROM 55 TO 60 DEGREES AS OUTSIDE AIR TEMPERATURE FALLS FROM 45 DEGREES TO 20 DEGREES. THE RESET PARAMETERS ARE ALL

ADJUSTABLE FROM THE UNIT GRAPHIC.

REGARDLESS OF THE OPERATING MODE OF THE AHU, THE LOW LIMIT SENSOR AT THE HEATING COIL DISCHARGE OF THE UNIT AND CONTROLLER AHU FUNCTION AS A LOW LIMIT BY OVERCALLING THE SUPPLY AIR SIGNAL AND MODULATING HEATING VALVE OPEN AS REQUIRED TO PREVENT AIR TEMPERATURE ENTERING THE COOLING COIL FROM FALLING BELOW 50 DEGREES (ADJUSTABLE)

UNTIL SUPPLY SENSOR DOWNSTREAM OF THE SUPPLY CAN TAKE CONTROL.

WHEN THE UNIT FIRST SWITCHES TO THE “OCCUPIED” MODE AND RETURN AIR TEMPERATURE AT THE AHU IS LESS THAN THE WARM-UP SETPOINT OF 70 DEGREES (ADJUSTABLE), THE POWERED EXHAUST FAN SHALL REMAIN OFF AND OUTSIDE AIR DAMPERS SHALL CLOSE UNTIL SETPOINT IS ACHIEVED. REHEAT COILS ON THE VAV BOXES THEN HEAT UNTIL RETURN AIR TEMPERATURE RISES ABOVE THIS SETPOINT. WHEN RETURN AIR ON THE UNIT RISES ABOVE THE SETPOINT, THE UNIT GOES TO THE “NORMAL” MODE WITH ERU RUNNING AND THE UNIT BEGINS TO MAINTAIN THE SUPPLY AIR SETPOINT AS DESCRIBED ABOVE.

“UNOCCUPIED” TEMPERATURE CONTROL - DURING THE “UNOCCUPIED” MODE, IF THE UNIT STARTS FOR LOW LIMIT OPERATION, RETURN AIR TEMPERATURE WILL BE BELOW THE WARM UP SETPOINT OF 70 DEGREES AND COOLING WILL BE LOCKED OUT WHILE THE UNIT RUNS AND THE REHEAT COILS ON THE VAV BOXES WILL PROVIDE HEATING. HOWEVER, IF THE SUPPLY FAN STARTS FOR HIGH LIMIT OPERATION, THE UNIT OPERATES ON 100% RETURN AIR AND THE CONTROLLER MAINTAINS THE SUPPLY AIR SETPOINT

BY MODULATING THE CHILLED WATER VALVE TO ALLOW INDIVIDUAL VAV BOXES TO COOL.

FIRE ALARM - IF THE FIRE ALARM SYSTEM GOES INTO ALARM, AN ALARM IS INPUT TO THE AHU CONTROLLER AND BOTH FANS STOP AND ALL DAMPERS CLOSE. WHEN THE FIRE ALARM SYSTEM IS RESET, THE FANS ARE AGAIN ALLOWED TO RUN, ONCE ALL DISCHARGE AND RETURN DAMPERS ARE POWERED OPEN. IF SUPPLY DUCT STATIC PRESSURE EXCEEDS THE SETPOINT OF A MANUAL RESET HIGH PRESSURE SWITCH, AN ALARM IS INPUT TO THE CONTROLLER AND ONLY THE SUPPLY FAN STOPS. WHEN IT IS

RESET, THE SUPPLY FAN IS AGAIN ALLOWED TO RUN.

FREEZE PROTECTION - IF FREEZESTAT LL-1 AT THE INLET TO THE COOLING COIL TRIPS, AN ALARM IS INPUT TO CONTROLLER AHU.

THIS CAUSES THE HEATING COIL VALVE CV-HC TO GO 100% OPEN REGARDLESS OF WHETHER THE UNIT FAN IS RUNNING. WHEN THE

FREEZESTAT IS RESET, THE HEATING VALVE IS AGAIN CONTROLLED AS DESCRIBED ABOVE.
