GENERAL:

1. THE BAS MUST FULLY CONTROL THE CHILLED WATER SYSTEM TO SATISFY LOAD REQUIREMENTS FOR CHILLED WATER TO THE

FACILITY. THE CHILLED WATER SYSTEM CONSISTS OF TWO AIR-COOLED CHILLERS AND TWO CHILLED WATER PUMPS. EACH CHILLER MUST HAVE CAPABILITY TO COMMUNICATE WITH THE BAS VIA BACNET COMMUNICATION AND MUST OPERATE ON INTERNAL CONTROLS AND SAFETIES WHEN IT IS ENABLED BY THE BAS. EACH CHILLER HAS A CONTROL VALVE TO ISOLATE THE CHILLER WHEN ITS USE IS NOT REQUIRED. THE CHILLED WATER PUMPS EMPLOY VARIABLE SPEED DRIVES CONTROLLED BY THE BAS.

2. THE CONTROLS MUST INCLUDE REMOTE SET POINT, EQUIPMENT ENABLE/DISABLE, EQUIPMENT LEAD/ LAG OR STANDBY CONFIGURATION, AND EQUIPMENT AUTOMATIC ROTATION TO MAXIMIZE CHILLED WATER SYSTEM OPERATING EFFICIENCIES. ONE AIR- COOLED CHILLER MUST BE DESIGNATED AS LEAD CHILLER AND THE OTHER AIR-COOLED CHILLER MUST BE DESIGNATED AS LAG CHILLER. ONE CHILLED WATER PUMP MUST BE DESIGNATED AS THE LEAD PUMP AND THE OTHER CHILLED WATER PUMP MUST BE

DESIGNATED AS THE STANDBY PUMP.

3. THE AIR-COOLED CHILLERS MUST BE OPERATED IN TWO DISTINCT MODES - COOLING MODE OR HEAT RECOVERY MODE. IN COOLING MODE, CHILLER IS USED TO PROVIDE CHILLED WATER TO THE BUILDING COOLING LOAD. IN HEAT RECOVERY MODE, CHILLER IS USED TO PROVIDE CHILLED WATER TO THE BUILDING COOLING LOAD AND HOT WATER TO THE BUILDING HEATING LOAD. REFER TO HEATING

HOT WATER CONTROL DIAGRAM AND SEQUENCES OF OPERATION FOR ADDITIONAL INFORMATION.

4. THE EQUIPMENT MUST BE DISTRIBUTED ACROSS MULTIPLE CONTROLLERS IN SUCH A MANNER THAT NO MORE THAN ONE AIR-COOLED CHILLER, ONE ISOLATION CONTROL VALVE, ONE WATER FLOW METER, AND ONE CHILLED WATER PUMP MUST BE CONTROLLED AND MONITORED USING A SINGLE CONTROLLER. LOSS OF ONE CONTROLLER MUST NOT CAUSE THE LOSS OF THE ENTIRE CHILLED WATER SYSTEM. PROGRAM BAS EQUIPMENT TO MEET THE REQUIRED OPERATION OF THE CHILLED WATER SYSTEM AS DESCRIBED HERE.

CHILLED WATER SYSTEM ENABLE MODE: WHEN THERE IS AT LEAST ONE REQUEST (ADJ.) FOR COOLING FROM ANY HVAC EQUIPMENT SUPPLIED

WITH CHILLED WATER, THE CHILLED WATER SYSTEM MUST BE ENABLED BY THE BAS.

1. CHILLER LOADING: INITIALLY, ONE CHILLER MUST OPERATE TO SATISFY THE CHILLED WATER LOAD AT START-UP. WHEN THE CHILLED

WATER SYSTEM IS ENABLED BY THE BAS, THE FOLLOWING MUST OCCUR:

A. LEAD CHILLER:

a. BAS MUST OPEN THE LEAD CHILLER ISOLATION VALVE. WHEN ISOLATION VALVE HAS BEEN PROVEN FULLY OPEN, THE

BAS MUST START THE LEAD CHILLED WATER PUMP.

b. WHEN THE LEAD CHILLED WATER PUMP HAS BEEN PROVEN TO BE ON AS SENSED BY DIFFERENTIAL PRESSURE SWITCH, THE BAS MUST ENABLE THE PUMP SPEED CONTROL AS DESCRIBED IN THE “CHILLED WATER PUMP SPEED CONTROL”.

c. ONCE MINIMUM CHILLED WATER FLOW RATE AS SENSED BY FLOW METER CH-#-CHWS-FM FOR LEAD AIR-COOLED CHILLER IS REACHED FOR 30 SECONDS (ADJ.), ENABLE THE CHILLER. MINIMUM CHILLED WATER FLOW RATE SETTING MUST BE SET AT THE VALUE CORRESPONDING TO THE FLOW RATE REQUIRED FOR THE CHILLER, WHICH MUST BE

PROVIDED BY THE CHILLER MANUFACTURER.

d. AFTER CHILLER INTERNAL SAFETIES ARE SATISFIED, THE LEAD CHILLER'S SELF-CONTAINED PACKAGED CONTROL SYSTEM MUST START AND OPERATE THE CHILLER TO MAINTAIN THE CHILLED WATER SUPPLY TEMPERATURE SET POINT.

B. LAG CHILLER: IF THE CHILLED W ATER SUPPLY TEMPERATURE AS SENSED BY TEMPERATURE SENSOR CHWS-T IS ABOVE CHILLED WATER SUPPLY TEMPERATURE SETPOINT FOR 15 MINUTES (ADJ.), THE BAS MUST EXECUTE THE FOLLOWING

OPERATIONS:

a. BAS MUST OPEN THE LAG CHILLER ISOLATION VALVE TO 100% IN 5% INCREMENTS (ADJ.). INCREMENTS ARE TO BE 10

SECONDS (ADJ.) EACH.

b. THE PID SPEED CONTROL SEQUENCE FOR THE LEAD CHILLED WATER PUMP MUST ADJUST THE PUMP SPEED TO

MAINTAIN THE CHILLED WATER DIFFERENTIAL PRESSURE AS SENSED BY PRESSURE SENSOR CHW-SYS-P AT THE

SETPOINT.

c. ONCE MINIMUM CHILLED WATER FLOW RATE AS SENSED BY FLOW METER CH-#-CHWS-FM FOR LAG AIR-COOLED CHILLER IS REACHED FOR 30 SECONDS (ADJ.), ENABLE THE CHILLER. MINIMUM CHILLED WATER FLOW RATE SETTING MUST BE SET AT THE VALUE CORRESPONDING TO THE FLOW RATE REQUIRED FOR THE CHILLER, WHICH MUST BE

PROVIDED BY THE CHILLER MANUFACTURER.

d. AFTER CHILLER INTERNAL SAFETIES ARE SATISFIED, THE LAG CHILLER'S SELF-CONTAINED PACKAGED CONTROL SYSTEM MUST START AND OPERATE THE CHILLER TO MAINTAIN THE CHILLED WATER SUPPLY TEMPERATURE SET POINT.

2. CHILLER UNLOADING:

A. LAG CHILLER: IF THE CHILLED W ATER SUPPLY TEMPERATURE AS SENSED BY TEMPERATURE SENSOR CHWS-T IS BELOW

CHILLED WATER SUPPLY TEMPERATURE SETPOINT FOR 15 MINUTES (ADJ.), THE BAS MUST EXECUTE THE FOLLOWING

OPERATIONS:

a. THE BAS MUST DISABLE THE LAG CHILLER.

b. AFTER A USER-DEFINED TIME DELAY, INITIALLY SET AT 120 SECONDS (ADJ.), CLOSE THE LAG CHILLER ISOLATION VALVE

TO 0% IN 5% INCREMENTS (ADJ.). INCREMENTS ARE TO BE 10 SECONDS (ADJ.) EACH.

c. THE PID SPEED CONTROL SEQUENCE FOR THE LEAD CHILLED WATER PUMP MUST ADJUST THE PUMP SPEED TO

MAINTAIN THE CHILLED WATER DIFFERENTIAL PRESSURE SETPOINT.

B. LEAD CHILLER: REFER TO CHILLED WATER SYSTEM DISABLE MODE SEQUENCE BELOW FOR LEAD CHILLER UNLOADING.

CHILLED WATER SYSTEM SEQUENCES OF OPERATION

CHILLED WATER SYSTEM DISABLE MODE: WHEN THERE IS NO REQUEST FOR COOLING FROM ANY HVAC EQUIPMENT SUPPLIED WITH CHILLED

WATER, THE CHILLED WATER SYSTEM MUST BE DISABLED BY THE BAS.

1. LEAD CHILLER: WHEN THE CHILLED WATER SYSTEM IS DISABLED BY THE BAS, THE FOLLOWING MUST OCCUR:

A. THE BAS MUST DISABLE THE LEAD CHILLER.

B. AFTER A USER-DEFINED TIME DELAY, INITIALLY SET AT 120 SECONDS (ADJ.), THE BAS MUST SET THE LEAD CHILLED WATER PUMP

SPEED TO 0 HZ AND STOP THE PUMP.

C. ONCE THE LEAD CHILLED WATER PUMP HAS BEEN PROVEN TO BE OFF THROUGH THE OUTPUT FROM THE PUMP VFD, THE BAS

MUST CLOSE THE LEAD CHILLER ISOLATION VALVE.

CHILLED WATER SUPPLY TEMPERATURE CONTROL: EACH CHILLER MUST BE CONTROLLED BY ITS PACKAGED CONTROLS TO MAINTAIN THE CHILLED WATER SUPPLY TEMPERATURE AT 44 °F (ADJ.). THE SET POINT MUST BE ADJUSTABLE THROUGH THE BAS.

LOSS OF CONTROL SIGNAL: UPON LOSS OF CONTROL SIGNAL BETWEEN BAS AND CHILLER, CHILLER MUST RUN INDEPENDENTLY AND OPERATE TO MAINTAIN ITS OWN CHILLED WATER SUPPLY TEMPERATURE SET POINT. A CRITICAL ALARM MUST BE GENERATED AT THE BAS OPERATOR’S

WORKSTATION.

CHILLER CYCLE: PROVIDE A TIME DELAY WHICH PREVENTS THE BAS FROM ATTEMPTING TO START OR STOP ANOTHER CHILLER FOR AN ADJUSTABLE TIME PERIOD AFTER A CHILLER IS STARTED OR STOPPED. THE TIME DELAY MUST NOT PREVENT THE BAS FROM IMMEDIATELY STARTING AN AVAILABLE CHILLER IN RESPONSE TO A FAILED CHILLER. THE TIME DELAY MUST BE INITIALLY SET AT 15 MINUTES (ADJ.), TO PREVENT RAPID CYCLING OF THE CHILLERS. COORDINATE WITH CHILLER MANUFACTURER AND ADJUST THE TIMING OF SYSTEM COMPONENTS TO PROVIDE

A STABLE YET RESPONSIVE FULLY OPERATIONAL SYSTEM.

CHILLER ROTATION:

1. THE BAS MUST TOTALIZE RUNTIME FOR CHILLERS AND MUST ROTATE CHILLERS IN A MANNER THAT EQUALIZES RUNTIME. THE BAS MUST, AT AN OPERATOR DEFINED INTERVAL INITIALLY SET TO WEEKLY, OR UPON OPERATOR REQUEST, EVALUATE THE LEAD CHILLER SELECTION AND RESELECT SO AS TO EQUALIZE RUNTIME. DURING THE ROTATION OF THE CHILLERS, THE LEAD CHILLER MUST BECOME THE LAG

CHILLER AND THE LAG CHILLER MUST BECOME THE LEAD CHILLER.

2. WHEN THE LEAD CHILLER IS ROTATED WITH LAG CHILLER, THE FOLLOWING MUST OCCUR:

A. A BAS MUST DISABLE THE LEAD AIR-COOLED CHILLER.

B. BAS MUST OPEN THE LAG CHILLER ISOLATION VALVE TO 100% TO 5% INCREMENTS (ADJ.). INCREMENTS ARE TO BE 10 SECONDS

(ADJ.) EACH.

C. BAS MUST CLOSE THE LEAD CHILLER ISOLATION VALVE TO 0% IN 5% INCREMENTS (ADJ.). INCREMENTS ARE TO BE 10 SECONDS

(ADJ.) EACH.

D. DURING OPENING/CLOSING OF ISOLATION VALVES, THE OPERATING LEAD CHILLED WATER PUMP MUST RAMP UP OR DOWN AS

REQUIRED TO MAINTAIN THE CHILLED WATER DIFFERENTIAL PRESSURE.

E. ONCE MINIMUM CHILLED WATER FLOW RATE AS SENSED BY FLOW METER CH-#-CHWS-FM FOR LAG AIR-COOLED CHILLER IS

REACHED FOR 30 SECONDS (ADJ.), ENABLE THE LAG CHILLER.

CHILLER FAILURE:

1. IF THE LEAD AIR-COOLED CHILLER SHOULD FAIL, AN ALARM MUST BE GENERATED AT THE BAS. ASSUMING THE LAG AIR-COOLED CHILLER IS

AVAILABLE FOR OPERATION, THE FOLLOWING MUST OCCUR:

A. BAS MUST DISABLE THE LEAD AIR-COOLED CHILLER.

B. BAS MUST OPEN THE LAG CHILLER ISOLATION VALVE TO 100% IN 5% INCREMENTS (ADJ.). INCREMENTS ARE TO BE 10 SECONDS

(ADJ.) EACH.

C. BAS MUST CLOSE THE LEAD CHILLER ISOLATION VALVE TO 0% IN 5% INCREMENTS (ADJ.). INCREMENTS ARE TO BE 10 SECONDS

(ADJ.) EACH.

D. DURING OPENING/CLOSING OF ISOLATION VALVES, THE OPERATING LEAD CHILLED WATER PUMP MUST RAMP UP OR DOWN AS

REQUIRED TO MAINTAIN THE CHILLED WATER DIFFERENTIAL PRESSURE.

E. ONCE MINIMUM CHILLED WATER FLOW RATE AS SENSED BY FLOW METER CH-#-CHWS-FM FOR LAG AIR-COOLED CHILLER IS

REACHED FOR 30 SECONDS (ADJ.), ENABLE THE LAG CHILLER.

2. A CHILLER THAT FAILS DURING OPERATION MUST AUTOMATICALLY BE ASSIGNED A DESIGNATION OF “FAILED” BY THE BAS. A CHILLER MUST

BE CONSIDERED “FAILED” IF: THE BAS SENSES A LOSS OF STATUS AT THE ASSOCIATED CHILLER OR THE BAS RECEIVES A FAULT ALARM

FROM THE CHILLER.

3. ANY CHILLER THAT IS TAKEN OUT OF OPERATION FOR MAINTENANCE MUST BE ASSIGNED A “FAILED” DESIGNATION BY THE OPERATOR. THE BAS MUST NOT ATTEMPT TO START A CHILLER WITH AN ASSIGNED DESIGNATION OF “FAILED”.

CHILLED WATER BYPASS VALVE CONTROL:

1. WHEN CHILLED WATER SYSTEM HAS BEEN ENABLED FOR 30 MINUTES AND THE MINIMUM CHILLED WATER FLOW RATE FOR ANY

ENABLED CHILLER IS BELOW THE SETPOINT, THE CHILLED WATER BYPASS VALVE, CHW -BYP-V-3, MUST BE MODULATED TO MAINTAIN THE

MINIMUM FLOW AT THE CHILLER WITH THE LEAST FLOW.

CHILLED WATER PUMP CONTROL:

1. CHILLED WATER PUMP HAND-OFF-AUTO OPERATION: HAND-OFF-AUTO SETTINGS MUST BE PROVIDED AS PART OF THE VARIABLE

FREQUENCY DRIVE THROUGH THE DRIVE’S KEYPAD. IN THE OFF MODE, THE PUMP MUST BE STOPPED. IN THE HAND MODE, THE PUMP MUST RUN CONTINUOUSLY. IN THE AUTO MODE, THE PUMP MUST BE STARTED AND STOPPED BY THE BAS.

2. CHILLED WATER PUMP LOCAL-REMOTE SPEED CONTROL: LOCAL–REMOTE SETTINGS MUST BE PROVIDED AS PART OF VARIABLE FREQUENCY DRIVE THROUGH THE DRIVE'S KEYPAD. IN THE LOCAL MODE, THE PUMP'S SPEED MUST BE CONTROLLED THROUGH A MANUAL SPEED CONTROL LOCATED AT THE RESPECTIVE DRIVE CONTROL PANEL. THE BAS MUST INDICATE PUMP THAT IS IN LOCAL CONTROL MODE BY ADDING "MANUAL" TO THE GRAPHIC FOR THAT PUMP AND CHANGE THE COLOR OF THE SPEED SHOWN ON THE GRAPHICS PAGE. IN THE REMOTE MODE, THE PUMP'S SPEED MUST BE CONTROLLED BY THE BAS.

3. CHILLED WATER PUMP START/STOP OPERATION: CHILLED WATER PUMPS MUST BE STARTED ACCORDING TO THE “ENABLE MODE” AND

STOPPED ACCORDING TO THE “DISABLE MODE” SEQUENCES.

4. CHILLED WATER PUMP ROTATION: A PROGRAM WILL BE PROVIDED TO AUTOMATICALLY ALTERNATE THE PUMPS WEEKLY (ADJUSTABLE) TO MAINTAIN EVEN USE. WHEN SW ITCHING THE LEAD AND STAND-BY PUMPS, THE STAND-BY PUMP MUST BE STARTED BEFORE THE LEAD PUMP IS STOPPED IN ORDER TO MAINTAIN MINIMUM FLOW THROUGH THE OPERATING CHILLER. DURING THE ROTATION OF THE CHILLED WATER PUMPS, THE LEAD PUMP MUST BECOME THE STANDBY PUMP AND THE STANDBY PUMP MUST BECOME THE LEAD PUMP.

5. CHILLED WATER PUMP STATUS: A DIFFERENTIAL PRESSURE SWITCH MUST BE USED TO MONITOR THE STATUS OF THE CHILLED WATER PUMP. IF THE STATUS INDICATED DOES NOT MATCH THE COMMANDED OUTPUT FOR THE PUMP AFTER A 60 SECONDS (ADJUSTABLE) TIME DELAY, A FAILURE ALARM MUST BE ISSUED, AND THE START COMMAND MUST BE CANCELED.

6. CHILLED WATER PUMP FAILURE:

A. IF A CHILLED WATER PUMP MUST FAIL, AN ALARM MUST BE GENERATED. ASSUMING THE STANDBY CHILLED WATER PUMP IS IDLE

AND AVAILABLE FOR OPERATION, THE BAS MUST AUTOMATICALLY ENABLE THAT PUMP TO REPLACE THE FAILED PUMP. AFTER

THE NEWLY STARTED PUMP IS IN OPERATION, THE FAILED PUMP MUST BE DISABLED.

B. CHILLED WATER PUMP THAT FAILS DURING OPERATION MUST AUTOMATICALLY BE ASSIGNED A DESIGNATION OF “FAILED”.

CHILLED WATER PUMP FAILURE MUST INCLUDE: LOSS OF STATUS AND VFD FAULT.

C. A CHILLED WATER PUMP THAT IS TAKEN OUT OF OPERATION FOR MAINTENANCE MUST BE ASSIGNED A DESIGNATION OF “FAILED” BY THE OPERATOR. THE BAS MUST NOT ATTEMPT TO START PUMPS WITH AN ASSIGNED DESIGNATION OF “FAILED”.

7. CHILLED WATER PUMP SPEED CONTROL:

A. THE BAS MUST MONITOR THE DIFFERENTIAL PRESSURE BETWEEN THE CHILLED WATER SUPPLY AND CHILLED WATER RETURN

PIPING THROUGH DIFFERENTIAL PRESSURE SENSOR AS SHOWN ON MECHANICAL DRAWINGS.

B. THE BAS MUST CONTROL THE SPEED OF THE LEAD CHILLED WATER PUMP VFD TO MAINTAIN THE CHILLED WATER DIFFERENTIAL

PRESSURE SETPOINT AT ALL TIMES.

C. IF THE DIFFERENTIAL PRESSURE AS SENSED BY DIFFERENTIAL PRESSURE SENSOR CHW-SYS-P DROPS BELOW THE

DIFFERENTIAL PRESSURE SET POINT, WHICH MUST BE INITIALLY SET AT 5 PSI (ADJUSTABLE), THE VFD SPEED MUST BE INCREASED. IF THE DIFFERENTIAL PRESSURE RISES ABOVE THE DIFFERENTIAL PRESSURE SET POINT, THE VFD SPEED MUST BE DECREASED. IF THE DIFFERENTIAL PRESSURE SENSOR MUST FAIL, AN ALARM MUST BE DISPLAYED AT THE BAS FRONT-END AND

THE BAS MUST RUN THE PUMP AT THE LAST SPEED COMMAND.

D. THE CHILLED WATER PUMP VFD MUST HAVE MINIMUM AND MAXIMUM SPEED SETTINGS. THE MAXIMUM AND MINIMUM PUMP SPEED MUST BE DETERMINED IN CONSULTING WITH THE BALANCING CONTRACTOR DURING THE TAB PROCESS.

E. WHEN A PUMP IS STOPPED, THE BAS SIGNAL MUST RETURN THE PUMP TO A SPEED OF ZERO.

8. LOSS OF CONTROL SIGNAL: UPON LOSS OF CONTROL SIGNAL BETW EEN PUMP VFD AND BAS, A CRITICAL ALARM MUST BE GENERATED

AT THE BAS OPERATOR’S WORKSTATION. PUMP VFD MUST RUN INDEPENDENTLY AND OPERATE AT THE DEFAULT SPEED, WHICH MUST

BE INITIALLY SET AT 70% (ADJUSTABLE).

LOSS OF COMMUNICATION: UPON LOSS OF COMMUNICATIONS BETWEEN CHILLER OR VFD AND BAS, AN ALARM MUST BE ACTIVATED AT THE BAS

FRONT-END.
