8. THE DDC SYSTEM SHALL BE TIED INTO EACH CHILLER AND PUMP FOR KW MONITORING AND RUN TIME MEASUREMENT.

9. THE CHILLED WATER SYSTEM IS DESIGNED TO OPERATE CONTINUOUSLY ALL YEAR ROUND.

10. CIRCUIT SETTERS SHALL BE SET TO MAXIMUM FLOW ALLOWED FOR EACH RISER BY TESTING AND BALANCING CONTRACTOR

B. CHILLER CONTROL

1. CHILLER OPERATION

1.1. CHILLERS SHALL BE AUTOMATICALLY STARTED AND STOPPED (SEQUENTIALLY) BY THE BAS. PRIMARY PUMPS ARE CAPABLE OF SERVING ANY CHILLER. CHILLER ISOLATION VALVES SHALL OPEN FULLY BEFORE PUMPS ARE STARTED. CONTROL OF INTERNAL CHILLER OPERATION SHALL BE THROUGH THE CONTROL PANEL PROVIDED BY THE CHILLER MANUFACTURER. AFTER STOPPING, A CHILLER SHALL NOT BE RESTARTED FOR 15 MINUTES(ADJ), AND, AFTER STARTING, SHALL RUN FOR AT LEAST 15 MINUTES(ADJ) BEFORE STOPPING. CHILLERS SHALL BE LIMITED TO TWO STARTS PER HOUR AND A MAXIMUM OF TEN STARTS IN ANY 24 HOUR PERIOD. SUPPLY WATER TEMPERATURE

FOR EACH CHILLER SHALL BE INITIALLY SET FOR 41°F.

1.2. UPON ACTIVATION OF THE LEAD CHILLER START SEQUENCE, THE DDC SYSTEM SHALL FIRST OPEN THE CHILLER WATER ISOLATION VALVES (ACV-1 OR ACV-2). ONCE THE VALVE POSITION IS VERIFIED BY ZC, THE LEAD PRIMARY LOOP PUMPS SHALL START. CHILLED WATER FLOW TO EACH OPERATING CHILLER SHALL BE MONITORED AND ALARMED VIA THE WATER FLOW TRANSMITTER. AFTER A 30 SECOND TIME DELAY (ADJUSTABLE FROM 0 TO 300 SECONDS TO PROVE FLOW), THE LEAD CHILLER SHALL BE ALLOWED TO START.

1.3. ONLY ONE PRIMARY PUMP AND ONE CHILLER SHALL OPERATE AT A TIME. IF EITHER CHILLER FAILS, IT SHALL BE LOCKED OUT. THE CHILLER'S ISOLATION VALVES SHALL CLOSE AND AN ALARM SHALL BE GENERATED. THE LAG CHILLER SHALL BE STARTED. THE BAS SHALL

NOT ATTEMPT TO START THE FAILED CHILLER UNTIL THE LOCKOUT IS MANUALLY RESET.

2. CHILLER LEAD/LAG CONFIGURATION

2.1. THE CHILLER SHALL OPERATE WITH 6 STAGES OF OPERATION ACCORDING TO CHILLER MANUFACTURER INTERNAL CONTROL.

2.2. THE DDC SHALL ROTATE THE LEAD/LAG CHILLER SELECTION ON EACH RESTART TO EQUALIZE RUN TIME.

2.3. COORDINATE PART LOAD AMPS CORRESPONDING WITH CHILLER PART LOAD % OF FULL LOAD TONS WITH CHILLER MFGR'S DATA.

3. CHILLER ACTIVATION / DEACTIVATION SEQUENCES:

3.1. ACTIVATE THE CHILLER.

3.2. SLOWLY OPEN THE LEAD CHILLER ISOLATION VALVE BEFORE STARTING THE LEAD PRIMARY PUMP.

3.3. AFTER CHILLED WATER FLOW TO THE LEAD CHILLER IS VERIFIED VIA THE DP SENSORS, THE LEAD CHILLER SHALL BE ACTIVATED.

3.4. DEACTIVATE THE CHILLER.

3.5. AFTER A 3 MINUTE DELAY. THE PRIMARY PUMP SHALL BE STOPPED. AFTER THE PUMP STOPS, SLOWLY CLOSE THE CHILLER ISOLATION

VALVE

C. PRIMARY AND SECONDARY PUMP CONTROL

1. SAFETIES AND ALARMS

1.1. IF PUMP FAILS TO OPERATE AFTER BEING COMMANDED ON, AN ALARM SHALL BE INDICATED AT THE BAS, THE LEAD PUMP SHALL SHUT

DOWN, AND THE LAG PUMP SHALL BE STARTED.

1.2. THE BAS SHALL MONITOR THE POSITIONS OF THE HOA AND NORMAL-TEST-BYPASS SWITCHES ON THE VFD.

1.3. THE BAS SHALL MONITOR THROUGH BACNET INTERFACE THE OPERATION OF THE CHILLERS.

1.4. THE BAS SHALL DISPLAY ALL CHILLER ALARM PANEL ALARMS AND OPERATING PARAMETERS THROUGH THE DDC SYSTEM TO THE BAS

FRONT END.

1.5. THE BAS SHALL ROTATE THE LEAD/LAG PUMP TO EQUALIZE RUN TIME.

2. OPERATION

2.1. PRIMARY PUMP SHALL RUN ANYTIME THE CHILLER IS COMMANDED TO RUN AND RUN AT CONSTANT VOLUME TO MEET THE DP SENSOR SETPOINT OF THE CHILLER. SETPOINT SHALL BE SET DURING TESTING, ADJUSTING AND BALANCING. THE VFD SHALL BE USED FOR TAB

ONLY, AND SHALL BE LOCKED WHEN TAB IS COMPLETED.

2.2. SECONDARY PUMP SHALL RUN UPON COOLING COMMAND FROM ANY EQUIPMENT AND RUN AT VARIABLE SPEED TO MEET THE DP SENSOR SETPOINT AT THE CHILLED WATER RISER. SETPOINT SHALL BE SET AND VERIFIED DURING TESTING, ADJUSTING AND BALANCING.

2.3. WHEN CHILLER SYSTEM IS FIRST STARTED, SECONDARY PUMP SHALL BE STARTED AT LOW SPEED AND SHALL OPERATE BY ITSELF FOR 0.5 HOUR (ADJ). THE PRESSURE DIFFERENTIAL (DP'S) SENSORS PROVIDED ON EACH RISER SHALL BE POLLED. THE DP WITH THE LOWEST READING AS CONFIRMED BY THE TAB CONTRACTOR SHALL BE USED TO CONTROL THE PUMP(S). DP SENSORS ARE USED TO CONTROL THE PUMP VARIABLE FREQUENCY DRIVE (VFD'S) AND INCREASE PUMP SPEED AS REQUIRED TO MAINTAIN DP SENSORS SETPOINT.

2.4. DESIGN DP SETPOINTS ARE SPECIFIED BELOW: (TO BE VERIFIED DURING TESTING, ADJUSTING, AND BALANCING)

OPERATING ROOM: 12.0 PSI

4"Ø RISER: 18.0 PSI

6"Ø RISER : 8.5 PSI

2.5. IF DIFFERENTIAL PRESSURE AT ANY SENSOR IS ZERO FOR 30 MINUTES (ADJ) OR HAS BEEN DETERMINED TO BE UNRELIABLE BY THE EMCS, IT SHALL BE REMOVED FROM THE MONITORING SEQUENCE AND AN ALARM SHALL BE ISSUED AT THE BAS. THIS ALARM SHALL BE RESET

AUTOMATICALLY WHEN THE SENSOR RETURNS TO AN OPERABLE STATE.

2.6. SHOULD THE MINIMUM FLOW ALLOWED FOR THE PUMP BE REACHED, ACV-3 SHALL OPEN UP TO MAINTAIN MINIMUM REQUIRED FLOW FOR THE PUMP.THE MINIMUM SPEED OF THE PUMPS SHALL BE SET BY THE MINIMUM PUMP FLOW AS REQUIRED BY THE PUMP MANUFACTURER (+ 10% SAFETY), OR THE MINIMUM VFD SPEED AS RECOMMENDED BY THE VFD MANUFACTURER, WHICHEVER IS GREATER.

2.7. THE CHILLER SHALL OPERATE WITH 6 STAGES OF OPERATION ACCORDING TO CHILLER MANUFACTURER INTERNAL CONTROL.

2.8. CHILLED WATER SUPPLY TEMPERATURE SETPOINT RESET
