CHILLED WATER SYSTEM

THE CHILLED WATER PUMPS AND CHILLERS SHALL BE ENERGIZED TO PROVIDE COOLING TO AIR HANDLING UNITS COOLING COILS.

OCCUPIED MODE:

THE CHILLERS SHALL BE ENABLED TO RUN WHENEVER:

• A DEFINABLE NUMBER OF CHILLED WATER COILS NEED COOLING

• AND THE OUTSIDE AIR TEMPERATURE IS GREATER THAN 54°F (ADJ.).

TO PREVENT SHORT CYCLING, THE CHILLERS SHALL RUN FOR AND BE OFF FOR MINIMUM ADJUSTABLE TIMES (BOTH USER DEFINABLE), UNLESS SHUTDOWN ON SAFETIES OR OUTSIDE AIR CONDITIONS. THE CHILLERS SHALL RUN SUBJECT TO THEIR OWN

INTERNAL SAFETIES AND CONTROLS.

AIR COOLED CHILLERS:

THE BAS SYSTEM SHALL INTERFACE TO THE CHILLER CONTROLS UTILIZING BACNET. THE BAS SHALL ENABLE THE CHILLER SYSTEM CONTROLLERS AND STAGE THE CHILLERS, ROTATING LEAD AND LAG CHILLERS. THE CHILLERS SHALL BE ENABLED A USER ADJUSTABLE TIME AFTER PUMP STATUSES ARE PROVEN ON. THE CHILLERS SHALL THEREFORE HAVE A USER ADJUSTABLE DELAY ON START. THE DELAY TIME SHALL BE SET APPROPRIATELY TO ALLOW FOR ORDERLY CHILLED WATER SYSTEM START-UP, SHUTDOWN AND SEQUENCING. THE CHILLERS SHALL RUN SUBJECT TO THEIR OWN INTERNAL SAFETIES AND CONTROLS. THE CHILLER SYSTEM CONTROLLERS SHALL CONTROL THEIR RESPECTIVE CHILLED WATER PUMPS AND ALSO SHALL PROVIDE STAGING AND SPEED OF THE COMPRESSORS BASED UPON THE BUILDING CHILLED WATER SUPPLY TEMPERATURE, 44°F (ADJ). THE BAS SHALL MONITOR THE CHILLER SYSTEM ALARMS AND RELAY/GENERATE ANY AND ALL SYSTEM ALARMS AT THE OPERATORS WORK

STATION.

CHILLED WATER PUMPS:

THE PRIMARY LOOP CHILLED WATER PUMPS (CHWP-1, 1A, 2, AND 2A) SHALL RUN ANYTIME THE CHILLER IS CALLED TO RUN. THE CHILLED WATER PUMPS SHALL ALSO RUN FOR FREEZE PROTECTION WHENEVER THE OUTSIDE AIR TEMPERATURE IS LESS THAN A USER DEFINABLE SETPOINT (ADJ.). THE CHILLED WATER PUMPS SHALL START PRIOR TO THE CHILLER BEING ENABLED AND SHALL STOP ONLY AFTER THE CHILLER IS DISABLED. THE CHILLED WATER PUMPS SHALL THEREFORE HAVE:

• A USER ADJUSTABLE DELAY ON START.

• AND A USER ADJUSTABLE DELAY ON STOP.

THE DELAY TIMES SHALL BE SET APPROPRIATELY TO ALLOW FOR ORDERLY CHILLED WATER SYSTEM START-UP, SHUTDOWN AND

SEQUENCING.

THE CHILLED WATER PUMPS SPEED SHALL BE CONTROLLED THROUGH THE VFD TO MAINTAIN THE FLOW DETERMINED BY THE

CHILLER CONTROLLER.

THE SECONDARY LOOP CHILLED WATER PUMPS (CHWP-3 AND 4) SHALL BE ENERGIZED THROUGH THE DDC CONTROLLER VIA OCCUPIED/UNOCCUPIED MODE THROUGH THE BUILDING BAS. THE CHILLED WATER PUMP SPEED SHALL BE CONTROLLED THROUGH

THE VFD TO MAINTAIN THE PRESSURE SETPOINT AT THE DIFFERENTIAL PRESSURE SENSOR.

ALL THE CHILLED WATER PUMPS ARE REDUNDANT AND SHOULD NOT OPERATE AT THE SAME TIME. THE BAS SHALL SCHEDULE/ROTATE THE PUMP AND STAND-BY PUMP ON A MONTHLY BASIS TO EQUALIZE RUN TIME HOURS. IN THE EVENT OF THE CHILLED WATER PUMP FAILURE, THE BAS SHALL ENERGIZE THE STAND BY CHILLED WATER PUMP AND GENERATE AN ALARM AT THE OPERATOR’S WORKSTATION. THE CHILLED WATER PUMPS SHALL PROVIDE PROOF OF OPERATION AT THE OPERATOR’S

WORKSTATION THROUGH THE USE OF A CURRENT SWITCH.

CHILLED WATER TEMPERATURE MONITORING:

THE FOLLOWING TEMPERATURES SHALL BE MONITORED:

• CHILLED WATER SUPPLY.

• CHILLED WATER RETURN.

AIR HANDLING UNIT SEQUENCE OF OPERATION (APPLICABLE TO ALL UNITS UNLESS NOTED OTHERWISE):

UNOCCUPIED MODE:

THE SUPPLY FAN WILL BE INDEXED OFF AND WILL REMAIN OFF UNTIL THE START OF ONE OF THE FOLLOWING MODES (WHERE APPLICABLE) NIGHT HIGH LIMIT, NIGHT LOW LIMIT, WARMUP, COOLDOWN, OR OCCUPIED MODE. THE RETURN AIR DAMPER WILL REMAIN OPEN AND WHERE

APPLICABLE THE OUTSIDE AIR DAMPERS WILL REMAIN CLOSED.

NIGHT LOW LIMIT MODE (AHU-5 & 6 ONLY):

ON A DROP IN SPACE TEMPERATURE BELOW THE NIGHT LOW LIMIT SETPOINT (NLL, 55°F ADJ.), THE SUPPLY FAN AND SPACE TEMPERATURE HEATING CONTROL WILL BE ENABLED. WHEN THE SPACE TEMPERATURE INCREASES ABOVE THE NLL SETPOINT AND THE NHL/NLL MINIMUM RUNTIME HAS EXPIRED (2 HRS, ADJ.); OR THE OCCUPIED SCHEDULE BECOMES ACTIVE, NLL WILL BE DISABLED. DURING NLL MODE THE ELECTRIC

HEAT WILL BE DISABLED.

NIGHT HIGH LIMIT MODE (AHU-5, 6, 10, 11, 12, & 13 ONLY):

ON A RISE IN SPACE TEMPERATURE ABOVE THE NIGHT HIGH LIMIT SETPOINT (NHL, 85°F ADJ.) THE SUPPLY FAN AND SPACE TEMPERATURE COOLING CONTROL WILL BE ENABLED. WHEN THE SPACE TEMPERATURE DECREASES BELOW THE NHL SETPOINT, AND THE NHL/NLL MINIMUM RUNTIME HAS EXPIRED (2 HRS, ADJ.); OR THE OCCUPIED SCHEDULE BECOMES ACTIVE, NHL WILL BE DISABLED.

MORNING WARMUP MODE (AHU-6 ONLY):

MORNING WARM-UP CYCLE SHALL BE INITIATED FROM ZONES AS REQUIRED. AN ADJUSTABLE MINIMUM NUMBER OF ZONES SHALL SATISFY MORNING WARM-UP REQUIREMENTS BEFORE THE AHU SUPPLY FAN SHALL BE STARTED. AN OPTIMUM START ALGORITHM WILL DETERMINE HOW EARLY THE UNIT NEEDS TO ENABLE TO SATISFY THE OCCUPIED HEATING SETPOINT BEFORE THE SCHEDULED OCCUPIED MODE BEGINS. IN THE MORNING WARM-UP CYCLE, THE AHU SUPPLY FAN SHALL BE DISABLED, OUTSIDE AIR DAMPERS SHALL REMAIN CLOSED, AND THE UNIT PRE-HEAT COIL SHALL BE DISABLED. IN WARMUP MODE, THE SUPPLY FAN AND SPACE TEMPERATURE HEATING CONTROL WILL BE ENABLED. ALL BUILDING HEATING SHALL BE ACCOMPLISHED LOCALLY AT THE REHEAT TERMINAL UNITS. WHEN THE OCCUPIED SCHEDULE BECOMES ACTIVE WARMUP

MODE WILL BE DISABLED AND THE UNIT WILL BEGIN OCCUPIED MODE CONTROL.

MORNING COOLDOWN MODE (AHU-6 ONLY):

MORNING COOL-DOWN CYCLE SHALL BE INITIATED FROM ZONES AS REQUIRED. AN ADJUSTABLE MINIMUM NUMBER OF ZONES SHALL REQUIRE MORNING COOL-DOWN BEFORE AHU SHALL BE STARTED. AN OPTIMUM START ALGORITHM WILL DETERMINE HOW EARLY THE UNIT NEEDS TO ENABLE TO SATISFY THE OCCUPIED COOLING SETPOINT BEFORE THE SCHEDULED OCCUPIED MODE BEGINS. IN THE MORNING COOL-DOWN CYCLE, THE AHU SUPPLY FAN START, OUTSIDE AIR DAMPERS SHALL REMAIN CLOSED, AND THE UNIT CHILLED WATER CONTROL VALVE SHALL BE ENABLED. DISCHARGE AIR TEMPERATURE CONTROL SHALL BE AS OCCUPIED MODE. WHEN THE OCCUPIED SCHEDULE BECOMES ACTIVE, COOLDOWN MODE WILL BE DISABLED AND THE UNIT WILL BEGIN OCCUPIED MODE CONTROL.

AFTERHOURS MODE (AHU-5, 6, 10, 11, 12, & 13 ONLY):

ON A CALL FOR AFTERHOURS OPERATION, BY PRESSING OVERRIDE BUTTON THE SUPPLY FAN WILL BE ENABLED AND THE UNIT WILL CONTROL AS IF IT WERE IN OCCUPIED MODE. THE UNIT WILL STAY IN AFTERHOURS OVERRIDE UNTIL THE OVERRIDE TIMER EXPIRES OR UNTIL THE START OF AN OCCUPIED CYCLE; WHICHEVER OCCURS FIRST. THE OVERRIDE TIME (2 HRS.) CAN BE ADJUSTED AT THE OPERATOR’S WORKSTATION.

SUPPLY FAN SPEED MODULATION (AHU-6 ONLY):

THE SUPPLY FAN SPEED WILL MODULATE AS REQUIRED TO MAINTAIN THE STARTUP/MANUAL DUCT STATIC PRESSURE SETPOINT (1.5” WC. ADJ.)

AS MEASURED BY THE EXISTING DUCT STATIC PRESSURE SENSOR TO REMAIN. ONCE ENABLED, THE MINIMUM SUPPLY FAN SPEED SIGNAL WILL BE 20% (ADJ.). IN MANUAL MODE, THE STATIC PRESSURE SETPOINT WILL REMAIN AT THE STARTUP/MANUAL SETPOINT. IN AUTOMATIC MODE, THE STATIC PRESSURE SETPOINT WILL BE RESET LINEARLY BASED ON THE PERCENT OPEN OF THE MOST REMOTE TERMINAL BOX.

OCCUPIED MODE:

IN OCCUPIED MODE, SUPPLY FAN SHALL BE ENABLED TO RUN THROUGH THE VARIABLE FREQUENCY DRIVE (VFD) AND SHALL RUN CONTINUOUSLY. WHERE APPLICABLE THE OUTSIDE AIR CONTROL DAMPER SHALL MODULATE TO MAINTAIN SCHEDULED OUTSIDE AIR VOLUME.

MAU-1N AND 2N SHALL BE CONTROLLED BY THE HOOD TO PROVIDE TEMPERED MAKEUP AIR WHEN THE EXHAUST FANS ARE OPERATING.

SPACE TEMPERATURE CONTROL (ALL BUT MAU-1N AND 2N):

HEATING (WHERE APPLICABLE) AND COOLING SIGNALS WILL GENERATE BASED ON THE DEVIATION OF THE SPACE TEMPERATURE FROM CURRENT SPACE TEMPERATURE HEATING AND COOLING SETPOINTS. ON A DROP IN SPACE TEMPERATURE BELOW THE CURRENT HEATING SETPOINT, THE UNIT WILL ENTER HEATING MODE, WHERE APPLICABLE. ON A RISE IN SPACE TEMPERATURE ABOVE THE CURRENT SPACE

TEMPERATURE COOLING SETPOINT, THE UNIT WILL ENTER COOLING MODE.

SUPPLY AIR TEMPERATURE CONTROL:

FOR COOLING AND HEATING MODES RESPECTIVELY AND WHERE APPLICABLE, THE CHILLED WATER VALVE AND HOT WATER VALVE WILL MODULATE OPEN AND CLOSED TO THE CHILLED WATER COIL AND HOT WATER COIL AS REQUIRED TO MAINTAIN THE CURRENT SUPPLY AIR TEMPERATURE SETPOINT. IN MANUAL MODE, THE SUPPLY AIR SETPOINT WILL REMAIN AT THE STARTUP/MANUAL SETPOINT.

FOR AHU-6 IN AUTOMATIC MODE, THE SUPPLY AIR TEMPERATURE SETPOINT WILL BE RESET LINEARLY BETWEEN 55°F (ADJ.) AND 65°F (ADJ.)

BASED ON THE HIGHEST COOLING SIGNAL FROM THE ASSOCIATED VAV BOXES. IF THE COOLING SIGNAL IS HIGH, THEN THE SUPPLY AIR TEMPERATURE SETPOINT WILL BE RESET TOWARD THE MINIMUM. IF THE COOLING SIGNAL IS LOW, THEN THE SUPPLY AIR TEMPERATURE

SETPOINT WILL BE RESET TOWARD THE MAXIMUM.

FOR AHU-A1, A2, B1, AND B3, THE MULTIZONE DAMPERS SHALL MODULATE TO BYPASS THE COOLING COIL WHEN THE ZONE IS IN HEATING MODE.

ALARMS:

THE FOLLOWING SOFTWARE ALARMS WILL BE GENERATED AND DISPLAYED AT THE OPERATOR’S WORKSTATION:

• SPACE TOO WARM (3°F GREATER THAN COOLING SETPOINT)

• SPACE TOO COLD (3°F LESS THAN HEATING SETPOINT)

• NONFUNCTIONAL SPACE TEMP SENSOR ALARM (GREATER THAN 120°F OR LESS THAN 40°F)

• HIGH SUPPLY AIR TEMP (GREATER THAN 180°F)

• LOW SUPPLY AIR TEMP (LESS THAN 45°F)

• BAD SUPPLY TEMP SENSOR ALARM (GREATER THAN 180°F OR LESS THAN -20°F)

• HIGH MIXED AIR TEMP (GREATER THAN 85°F, ADJ.)

• LOW MIXED AIR TEMP (LESS THAN 45°F, ADJ.)

• BAD MIXED AIR TEMP SENSOR ALARM (GREATER THAN 180°F OR LESS THAN -20°F)

• BAD RETURN AIR TEMP SENSOR ALARM (GREATER THAN 180°F OR LESS THAN -20°F)

• SUPPLY FAN ALARM (COMMAND WITH NO STATUS)

• FILTER ALARM (WHEN RUNTIME EXCEEDS 3000 HOURS, (ADJ.))

• FILTER ALARM (WHEN FILTER DIFFERENTIAL IS GREATER THAN 1” WC., (ADJ.))

SAFETIES: THE FOLLOWING SAFETIES WILL BE MONITORED AS A STATUS INPUT AND WILL BE DISPLAYED AT THE OPERATOR’S WORKSTATION:

• FIRE ALARM/SMOKE DETECTOR: ON A SIGNAL FROM ANY SMOKE DETECTOR ASSOCIATED WITH THE UNIT THE SUPPLY FAN WILL BE DE-

ENERGIZED VIA THE FACP RELAY MODULE (HARDWIRED INTERLOCK), EXCEPT FOR UNITS NOTED BELOW.

• AHU-A1, A2, B1, AND B3, ON A SIGNAL FROM THE BUILDING ZONE FIRE ALARM OR EMERGENCY VENT SWITCH, MAXIMUM OUTSIDE AIR

DAMPER SHALL OPEN.

• HIGH STATIC PRESSURE: IF THE SUPPLY STATIC PRESSURE EXCEEDS 10" WC. (ADJ.) AS MEASURED BY THE HIGH STATIC PRESSURE

SWITCH, THE SUPPLY FAN WILL BE DE-ENERGIZED (HARDWIRED INTERLOCK).

• FREEZE PROTECTION: WHEN THE TEMPERATURE DROPS BELOW 40°F (ADJ.) AS MEASURED BY A SINGLE LOW LIMIT SENSOR, THE FAN SHALL
