CHILLED WATER SYSTEM CONTROL SEQUENCE

1. CHILLER CONTROLS

A. THE PACKAGED AIR COOLED CHILLERS SHALL BE CONTROLLED BY THEIR OWN INTEGRAL CONTROL PACKAGE SET UP TO MAINTAIN A LEAVING WATER TEMPERATURE OF 42°F. TEMPERATURE SETPOINT SHALL BE DONE VIA THE BMS.

B. THE BMS SHALL ENABLE AND DISABLE EACH CHILLER FROM THE FRONT END ALONG WITH THE ABILITY TO STAGE ON EACH CHILLER. UPON DISABLING OR ENABLING A CHILLER, THE RESPECTIVE CHILLER ISOLATION CONTROL VALVES SHALL OPERATE PER THE FOLLOWING:

1. CV-1 SHALL BE OPENED AND CV-2 CLOSED WHEN CH-1 IS ENABLED.2. CV-2 SHALL BE OPENED AND CV-1 CLOSED WHEN CH-2 IS ENABLED.3. ONCE ENABLED THE LAG CHILLER ISOLATION VALVE SHALL OPEN (50% -

AJUSTABLE). AT THE SAME TIME THE LEAD CHILLER SHALL BE INITIATED FOR SHUTDOWN. ONCE THE CHILLER HAS SAFELY SHUT DOWN, THE RESPECTIVE ISOLATION VALVE SHALL CLOSE AND THE LAG CHILLER ISOLATION VALVE SHALL FULLY OPEN. ONCE THE LAG CHILLER DETECTS FLOW, THE CHILLER SHALL BEGIN TO STAGE ON COOLING.

C. THE BMS SHALL LEAD/LAG THE CHILLERS AND PROGRAM AN EQUAL RUNTIME SCHEDULE FOR EACH CHILLER.

D. IF THE LEAD CHILLER FAILS, THE LAG CHILLER SHALL AUTOMATICALLY BE ENABLED. FAILURE SHALL BE DETERMINED VIA A HIGH LEAVING WATER TEMPERATURE OF 50°F (ADJUSTABLE).

E. NEW TEMPERATURE SENSORS SHALL BE INSTALLED FOR THE CHILLER SUPPLY AND RETURN TEMPERATURES AS INDICATED ON THIS DRAWING (TT-001 AND TT-004)

F. PROVIDE SOFTWARE FIELD DEVICES AND FRONT END MODIFICATIONS AS REQUIRED TO SEND E-MAIL ALERTS (24/7 - 7 DAYS/WEEK) IF A CHILLER/PUMP FAILURE OCCURS.

2. NEW CHILLED WATER PUMP CONTROL (CHWP-1 AND 2)

A. VFD'S SHALL BE PROVIDED FOR EACH PUMP. THE LEAD PUMP SHALL OPERATE CONTINUOUSLY AND BE CONTROLLED TO MAINTAIN A GPM FLOW RATE OF 290.

B. THE MINIMUM PUMP SPEED OF THE VFD'S WILL BE SET TO MAINTAIN A MINIMUM FLOW OF 290 GPM THRU THE LEAD CHILLER AS MEASURED FROM THE FLOW METER FM-001 SERVING THE MAIN CHILLER LOOP.

C. THE VFD'S SHALL HAVE THE ABILITY TO LEAD/LAG CONTROL THE PUMPS AND PROGRAM AN EQUAL RUNTIME SCHEDULED FOR EACH PUMP SUCH THAT THEY SWITCHOVER EVERY WEEK.

D. THE BMS MAY OVERRIDE THE LEAD LAG PUMP STAGING IN THE OPERATOR WORKSTATION. THE OPERATOR HAS THE ABILITY TO OVERRIDE ANY PROGRAM FUNCTION (i.e. PUMP START/STOP AND SPEED SETTING).

E. THE CHILLER PUMPS CHWP-1 & CHWP-2 SHALL BE STARTED & STOPPED VIA THE TRIDIUM CONTROL PANEL AND HARD WIRE INTERLOCKS INTO THE CHILLER PANELS (IF NEEDED). ATC SUBCONTRACTOR TO WORK WITH THE CHILLER START-UP TECHNICIAN.

3. EXISTING TRANE CHILLER CONTROLS

A. THE EXISTING TRANE CHILLER CONTROL PANEL SHALL BE REMOVED AND ALL CHILLER CONTROL POINTS MOVED ONTO THE TRIDIUM BUILDING CONTROL SYSTEM.

ATC SCOPE OF WORK SEQUENCE

1. HVAC CONTROLS AND ELECTRICAL

A. HVAC CONTROLS AND ELECTRICAL SCOPE OF WORK

1. PROVIDE AND INSTALL ALL CONTROL DEVICES, WIRING, INTERLOCKS, RELAYS, TRANSFORMERS, FLOW SWITCHES, TEMPERATURE SENSORS, HIGH LIMITS, LOW WATER CUT-OFFS, PANELS, ETC. INSTALLATION, START UP, AND COMMISSIONING FOR FULLY OPERATIONAL CONTROL SYSTEMS.2. PROVIDE AND INSTALL ALL CONTROL DEVICES AS INDICATED ON THE HVAC

CONTROL DIAGRAMS.3. PROVIDE AND INSTALL POWER WIRING FOR ALL NEW CONTROL PANELS, PUMPS, FANS AND FIELD DEVICES AS INDICATED ON THE CONTROL DIAGRAM.4. CONNECT INTO THE LOCAL 120V-PH ELECTRICAL PANELS. PROVIDE ALL NEW

CIRCUIT BREAKERS NEEDED FOR THE NEW INSTALLATION.5. CONTROLS CONTRACTOR SHALL HAVE AT LEAST 5 YEARS EXPERIENCE INSTALLING DDC BLDG AUTOMATION SYSTEMS.6. INSTALLATION OF ALL UNDERGROUND CONTROL WIRING (IN CONDUIT) FROM

OUTSIDE CHILLER AREA TO INSIDE THE BUILDING. ALL EXCAVATING, BACKFILLING, ETC. TO INSTALL THE CONTROL WIRING SHALL BE THE RESPONSIBILITY OF THE

ATC CONTRACTOR.

B. CONTROL WIRING

1. ALL ELECTRIC WIRING, LOW VOLTAGE POWER WIRING, AND WIRING CONNECTIONS REQUIRED FOR THE INSTALLATION OF THE TEMPERATURE CONTROL SYSTEM, AS SPECIFIED HEREIN, SHALL BE PROVIDED BY THE INSTALLING

CONTRACTOR UNLESS SPECIFICALLY SHOWN ON THE ELECTRICAL DRAWINGS.2. ALL POWER AND CONTROL WIRING SHALL COMPLY WITH ALL REQUIREMENTS OF THE LOCAL AND NATIONAL ELECTRICAL CODE.3. ALL CONTROL WIRING SHALL BE INSTALLED TO MEET STATE AND LOCAL CODES. INSTALL CONTROL WIRING IN CONDUIT EXPOSED IN MECHANICAL ROOMS.4. ALL POWER WIRING SHALL BE RUN IN CONDUIT.5. ALL POWER WIRING SHALL BE INSTALLED AND SIZED BY THE NATIONAL ELECTRIC CODE.6. ALL CONTROL AND POWER WIRING SHALL BE INSTALLED BY A LICENSED ELECTRICIAN IN THE STATE OF RHODE ISLAND WITH THE PROPER PROJECT

PERMITS. THE FINAL INSTALLATION SHALL BE APPROVED BY THE CITY ELECTRICAL INSPECTOR.

7. CONDUIT: - NO CONDUIT, FOR ANY PART OF THE ATC SYSTEM, SHALL BE SMALLER THAN 1/2"

IN SIZE. NO CONDUIT SHALL HAVE MORE THAN (4) 90° BENDS IN ANY ONE RUN AND WHERE NECESSARY, PULL BOXES SHALL BE PROVIDED.

- FLEXIBLE STEEL CONDUIT SHALL BE USED FOR CONNECTION TO ALL ATC EQUIPMENT/DEVICES AND MOTORS. ALL FLEXIBLE CONNECTIONS SHALL INCLUDE A GROUNDING CONDUCTOR FROM THE OUTLET BOX TO THE EQUIPMENT BEING

CONNECTED. FLEXIBLE STEEL CONDUIT EXPOSED TO THE WEATHER SHALL BE LIQUID TIGHT.

C. SUBMITTALS REQUIRED
