CHILLED WATER SYSTEM :

GENERAL: THE FACILITY SHALL BE SUPPLIED WITH CHILLED WATER FROM AIR-COOLED CHILLER, AC-1. THE DESIGN CHILLED WATER SUPPLY TEMPERATURE IS 45°F.

COOLING: A CALL FOR COOLING IS DETERMINED BY ANY COOLING COIL VALVE BEING 30 PERCENT OPEN FOR A PERIOD OF MORE THAN 3 MINUTES. UPON A CALL FOR COOLING, THE CHILLER AND INTEGRAL PUMPING

PACKAGE SHALL BE ENERGIZED AND RUN FOR A MINIMUM OF 30 MINUTES. THE CHILLER MANUFACTURER'S CONTROL PANEL SHALL MAINTAIN CHILLED WATER SETPOINT (45°F). AN ANTI-CYCLE TIMER SHALL PREVENT THE CHILLER FROM BEING STARTED FOR A PERIOD OF 15 MINUTES AFTER IT SHUTS DOWN DUE TO LOW BUILDING COOLING DEMAND. THE CHILLER MANUFACTURER'S MINIMUM ON AND OFF TIMES MUST BE OBSERVED. THE

ABOVE SEQUENCE SHALL BE ACCOMPLISHED THROUGH THE BUILDING DDC SYSTEM AND CHILLER MANUFACTURER'S CONTROL PANEL. ALL ALARMS AND POINT INFORMATION RESIDING IN THE CHILLER CONTROL PANEL, SHALL BE AVAILABLE THROUGH THE BUILDING DDC SYSTEM.

CHILLER SHALL UTILIZE AN INTEGRAL PUMPING PACKAGE. PUMPS SHALL BE EQUIPPED WITH VARIABLE FREQUENCY DRIVES BUT SHALL OPERATE AT CONSTANT SPEED. PUMPS SHALL OPERATE IN A LEAD/STANDBY

CONFIGURATION, AND THE LEAD PUMP DESIGNATION SHALL ALTERNATE ON A WEEKLY BASIS. IN THE EVENT THE PRIMARY PUMP FAILS TO START DURING OPERATION, IF THE LEAD PUMP PROOF SWITCH DOES NOT DETECT

FLOW WITHIN 30 SECONDS FROM START SIGNAL, THE DDC CONTROLLER SHALL DE-ENERGIZE THE FAILED PUMP, START THE STANDBY PUMP, AND TRANSMIT A PUMP FAILURE ALARM. A PROGRAMMED ANTI-RECYCLE TIMER

SHALL PREVENT PUMP SHORT CYCLING. THE DDC CONTROLLER SHALL AUTOMATICALLY ATTEMPT A RESTART OF THE CIRCULATING PUMPS ON A PERIODIC BASIS TO ACCOMMODATE SERVICE SHUTDOWNS AND EXTENDED

POWER OUTAGES.

HEATING HOT WATER SYSTEM

GENERAL: THE HOT WATER SYSTEM SHALL BE CONTROLLED BY THE BOILER MANAGEMENT SYSTEM. CONTROLLER SHALL MONITOR BOILERS'

STATUS AND HOT WATER SUPPLY TEMPERATURES. BOILERS SHALL OPERATE IN LEAD/LAG CONFIGURATION AND THE PUMPS SHALL

OPERATE IN A LEAD/STAND-BY CONFIGURATION ALTERNATING LEAD BOILERS/PUMPS STATUS WEEKLY BY SELECTING BOILER/PUMP WITH THE

LEAST TOTAL ACCUMULATED RUN TIME (HOURS). SECONDARY PUMPS ARE SIZED FOR CONNECTED LOAD AND ARE FULLY REDUNDANT.

IF THERE IS AN ALARM IN ANY BOILER OR IF A FAULT OCCURS IN THE BOILER MANAGEMENT SYSTEM, (AS DETERMINED FROM THE BINARY

FAULT OUTPUT OF THE CONTROLLER), THE ASSOCIATED BOILER WILL BE COMMANDED OFF, AND AN ALARM SHALL BE GENERATED.

ON DETECTION OF A HIGH DISCHARGE BOILER TEMPERATURE, AS DETERMINED BY THE BOILER HIGH LIMIT ALARM, THE BOILER SHALL BE

DISABLED, AND AN ALARM SHALL BE GENERATED.

BOILER (B-1, B-2 ) AND PRIMARY HOT WATER PUMP CONTROL (RP-1, RP-2 ): ON A CALL FOR HEATING AT ANY AHU OR VAV TERMINAL FOR MORE

THAN THREE (3) MINUTES, THE DDC CONTROLLER SHALL SEND A SIGNAL TO THE BOILER MANAGEMENT SYSTEM THAT HEATING IS REQUIRED.

WHEN THE DDC CONTROL SYSTEM RECEIVES A CALL FOR HEATING, THE BOILER MANAGEMENT SYSTEM SHALL BE ENGAGED AND SHALL

ENABLE THE LEAD BOILER. THE LEAD BOILER AND ASSOCIATED PRIMARY HOT WATER PUMP SHALL BE ENERGIZED. UPON A DROP IN MAIN HW

LOOP TEMPERATURE BELOW SETPOINT, THE LAG BOILER AND ASSOCIATED PRIMARY HOT WATER PUMP SHALL BE ENERGIZED.

SECONDARY HOT WATER PUMPS, SHWP-1 AND SHWP-2: THE CONTROL STRATEGY INCLUDES OPERATING VARIABLE SPEED PUMPS IN ORDER

TO MINIMIZE PUMPING POWER REQUIREMENTS. THE SPEED DRIVE OF THE VARIABLE SPEED PUMP(S) IS CONTROLLED TO MAINTAIN A

DIFFERENTIAL PRESSURE SETPOINT. THE DDC CONTROLLER SHALL BE DESIGNED TO START AND STOP THE PUMPS AND MODULATE THEIR

SPEEDS AS REQUIRED TO MEET THE SYSTEM DEMANDS. THE SYSTEM SHALL BE DESIGNED TO MAINTAIN A DIFFERENTIAL PRESSURE

SETPOINT AT A REMOTE LOCATION.

SECONDARY HOT WATER PUMPS SHALL BE CONTROLLED BY THE DDC SYSTEM. PUMPS SHALL BE ENERGIZED AND RUN ON A CALL FOR

HEATING AT ANY AHU OR VAV TERMINAL FOR MORE THAN THREE (3) MINUTES. THE DDC CONTROLLER SHALL ALTERNATE PUMP LEAD

STATUS WEEKLY BY SELECTING THE PUMP WITH THE LEAST TOTAL ACCUMULATED RUN TIME AS CALCULATED AND STORED AT THE DDC

CONTROLLER. IF EITHER SELECTED LEAD PUMP'S PROOF SWITCH DOES NOT DETECT FLOW WITHIN 30 SECONDS FROM THE START SIGNAL, THE DDC CONTROLLER SHALL DE-ENERGIZE THE FAILED PUMP, START THE STANDBY PUMP, AND TRANSMIT A PUMP FAILURE ALARM. A

PROGRAMMED ANTI-RECYCLE TIMER SHALL PREVENT PUMP SHORT CYCLING. THE DDC CONTROLLER SHALL AUTOMATICALLY ATTEMPT A

RESTART OF THE CIRCULATING PUMPS ON A PERIODIC BASIS TO ACCOMMODATE SERVICE SHUTDOWNS AND EXTENDED POWER OUTAGES.

HOT WATER RESET CONTROL: THE SECONDARY HOT WATER SUPPLY TEMPERATURE SETPOINT SHALL BE DETERMINED BY THE OUTSIDE AIR TEMPERATURE. THE HOT WATER SUPPLY TEMPERATURE SETPOINT SHALL BE RESET PROPORTIONALLY AS FOLLOWS: AS AIR TEMPERATURE RISES

FROM 20°F TO 60°F, RESET SECONDARY HWS FROM 120°F DOWN TO 100°F.

BOILER EMERGENCY SHUT-OFF CONTROL: PROVIDE TWO POSITION "ON-OFF" SWITCHES LABELED "BOILER EMERGENCY SHUT-OFF" LOCATED

AS INDICATED WHICH SHALL BE HARDWIRE INTERLOCKED WITH THE BOILERS' CONTROL PANEL. WHEN INDEXED TO THE "ON" POSITION, THE

BOILERS SHALL OPERATE UNDER NORMAL CONTROL OF THE DDC CONTROL SYSTEM. WHEN INDEXED TO THE "OFF" POSITION, THE BOILERS

SHALL BE DISABLED, AND THE GAS BURNERS TO EACH BOILER SHALL BE SHUTDOWN. MANUAL RESET SHALL BE REQUIRED.

ALARMS: IF THERE IS AN ALARM IN ANY BOILER OR IF A FAULT OCCURS IN THE BOILER MANAGEMENT SYSTEM, (AS DETERMINED FROM THE

BINARY FAULT OUTPUT OF THE CONTROLLER), THE ASSOCIATED BOILER ISOLATION VALVE SHALL CLOSE, AND AN ALARM SHALL BE

GENERATED. ON DETECTION OF A HIGH DISCHARGE BOILER TEMPERATURE, AS DETERMINED BY THE BOILER HIGH LIMIT ALARM, THE BOILER

MANAGEMENT SYSTEM SHALL BE DISABLED AND AN ALARM SHALL BE GENERATED. ALARM FOR LEAVING WATER TEMPERATURE EXCEEDING

140°F OR FALLING 10°F BELOW THE SCHEDULED HWS TEMPERATURE SETPOINT. ALARM IF ANY BOILER OR PUMP FAILS TO START OR FAILS
