SYSTEM GENERAL DESCRIPTION:

THE CHILLED WATER SYSTEM CONSISTS OF THE FOLLOWING:

ONE (1) CHILLER

TWO (2) MANIFOLDED PRIMARY CHILLED WATER PUMPS, CONFIGURED AS ONE (1) LEAD AND ONE (1) STANDBY TWO (2) MANIFOLDED SECONDARY CHILLED WATER PUMPS, CONFIGURED AS ONE (1) LEAD AND ONE (1) LAG

THE BUILDING AUTOMATION SYSTEM (BAS) CONTROLLER PROVIDES STAND-ALONE CONTROL OR CONTROL FROM A HIGHER-LEVEL BAS AND PROVIDES START/STOP CONTROL FOR THE CHILLED WATER PUMPS AND PROVIDES LEAD/STANDBY CONTROL OF THE SECONDARY CHILLED WATER PUMPS IN ORDER TO MAINTAIN THE SYSTEM

CHILLED WATER SYSTEM DIFFERENTIAL PRESSURE SETPOINT (ADJ.).

CHILLED WATER SYSTEM ENABLE/DISABLE:

THE CHILLED WATER SYSTEM SHALL BE ENABLED VIA A POINT CONTROLLED BY A HIGHER-LEVEL BAS. THE BAS CONTROLLER SHALL THEN START THE LEAD SYSTEM PUMP. WHEN RUN STATUS FOR THAT PUMP IS PROVEN, THE BAS CONTROLLER SHALL REPORT THAT STATUS TO THE HIGHER-LEVEL BAS. THE HIGHER-LEVEL BAS SHALL THEN

REQUESTS A CHILLER TO RUN.

THE PRIMARY CHILLED WATER PUMP SHALL BE ENABLED ON A CONTACT CLOSURE FROM ANY SYSTEM CHILLER.

WHEN ENABLED, THE BAS CONTROLLER SHALL START PRIMARY CHILLED WATER PUMP.

THE CHILLED WATER SYSTEM SHALL BE DISABLED WHEN BUILDING IS UNOCCUPIED UNLESS THERE IS A CALL FOR COOLING FROM ANY ZONE. WHEN THE CHILLED WATER SYSTEM IS DISABLED, THE SECONDARY CHILLED WATER PUMP SHALL BE OFF AND THE PRIMARY PUMP SHALL BE OFF UNLESS REQUESTED BY THE CHILLER.

PRIMARY CHILLED WATER PUMP START/STOP:

THE BAS CONTROLLER SHALL START A CHILLED WATER PUMP THROUGH A CONTACT CLOSURE OF THE PUMPS

MOTOR STARTER ENABLE CONTACTS.

PRIMARY CHILLED WATER PUMP STATUS:

THE BAS CONTROLLER SHALL DETECT CHILLED WATER PUMP RUN STATUS BY A CURRENT SWITCH.

PRIMARY CHILLED WATER PUMP FAILURE:

IF THE PUMP START/STOP RELAY IS ENABLED AND THE CURRENT SWITCH STATUS IS OFF FOR MORE THAN 30 SECONDS (ADJ.), THE BAS CONTROLLER SHALL ANNUNCIATE A CHILLED WATER PUMP FAILURE ALARM TO THE BAS. ONCE THE PROBLEM HAS BEEN CORRECTED, THE OPERATOR SHALL BE ABLE TO CLEAR THE ALARM FAILURE FROM THE BAS CONTROLLER FROM A BAS OR BY MANUALLY OVERRIDING THE PUMP ON MOMENTARILY.

SECONDARY CHILLED WATER PUMP START/STOP:

THE BAS CONTROLLER SHALL START A SECONDARY CHILLED WATER PUMP THROUGH A CONTACT CLOSURE OF

THE PUMPS VFD RUN-ENABLE CONTACTS.

SECONDARY CHILLED WATER PUMP STATUS:

THE BAS CONTROLLER SHALL DETECT SECONDARY CHILLED WATER PUMP RUN STATUS BY A VFD CURRENT

SWITCH.

SECONDARY CHILLED WATER PUMP LEAD/LAG:

THE SECONDARY CHILLED WATER PUMP LEAD/LAG SEQUENCE: CHILLED WATER PUMPS SHALL ROTATE ON THE 1ST AND 15TH OF THE MONTH. FROM THE BAS CONTROLLER HUMAN-INTERFACE PANEL OR A BAS WORKSTATION, AN OPERATOR SHALL BE ABLE TO MANUALLY CHANGE THE LEAD/LAG SEQUENCE.

IF THE CHILLED WATER SYSTEM DIFFERENTIAL PRESSURE FALLS 0.5 PSIG (ADJ.) BELOW SETPOINT AND THE LEAD PUMP IS AT 100% (ADJ.) FOR MORE THAN 5 MINUTES (ADJ.), THE NEXT PUMP IN THE SEQUENCE SHALL START. IF THE PUMP SPEED CONTROL OUTPUT IS BELOW 40% (ADJ.) FOR MORE THAN 5 MINUTES (ADJ.), THE LAST

OPERATING PUMP IN THE SEQUENCE SHALL BE DISABLED.

SECONDARY CHILLED WATER PUMP FAILURE:

IF THE LEAD START/STOP RELAY IS ENABLED AND THE CURRENT SWITCH STATUS IS OFF FOR MORE THAN 30 SECONDS (ADJ.), THE BAS CONTROLLER SHALL ANNUNCIATE A SECONDARY CHILLED WATER PUMP FAILURE ALARM TO THE BAS AND START THE LAG PUMP. WHEN A SECONDARY CHILLED WATER PUMP FAILURE EXISTS, LEAD/LAG AUTOMATION SHALL BE DISABLED AND THE CURRENTLY RUNNING PUMP BECOMES THE LEAD PUMP.

ONCE THE PROBLEM HAS BEEN CORRECTED, THE OPERATOR SHALL BE ABLE TO CLEAR THE ALARM FAILURE FROM THE BAS CONTROLLER OR BAS WORKSTATION. THIS SHALL RE-ENABLE THE LEAD/LAG SEQUENCE.

SECONDARY CHILLED WATER PUMP SPEED:

THE BAS CONTROLLER SHALL MONITOR THE CHILLED WATER SYSTEM DIFFERENTIAL PRESSURE SENSOR. WHEN THE PUMP VARIABLE FREQUENCY DRIVE IS ENABLED, THE BAS CONTROLLER SHALL CONTROL THE ANALOG SPEED SIGNAL THAT IS SENT TO THE VARIABLE FREQUENCY DRIVES OF OPERATING PUMPS TO MAINTAIN A

CHILLED WATER SYSTEM DIFFERENTIAL PRESSURE SETPOINT OF 15.0 PSIG (ADJ.).

SECONDARY CHILLED WATER AHU PUMP PRESSURE SETPOINT OPTIMIZATION:

THE BAS SHALL CONTINUALLY MONITOR THE CHILLED WATER CONTROL VALVE POSITION OF ALL AHUS IN THE

CHILLED WATER SYSTEM.

AT CHILLED WATER SYSTEM STARTUP, THE CHILLED WATER SYSTEM PRESSURE SETPOINT SHALL BE 100% OF THE MAXIMUM PRESSURE SETPOINT. WHEN ALL CHILLED WATER VALVES ARE LESS THAN 85% OPEN, THE CHILLED WATER SYSTEM DIFFERENTIAL PRESSURE SETPOINT SHALL BE LOWERED BY 0.1 PSIG (ADJ.) OF THE CURRENT CHILLED WATER SYSTEM DIFFERENTIAL PRESSURE SETPOINT. THIS OCCURS EVERY 5 MINUTES UNTIL AT LEAST ONE VALVE IS MORE THAN 85% OPEN, OR IF THE SETPOINT IS EQUAL TO THE MINIMUM CHILLED WATER SYSTEM DIFFERENTIAL PRESSURE SETPOINT, OR IF THE PUMP VARIABLE FREQUENCY DRIVES ARE AT A MINIMUM SPEED

SETTING (22 HZ).

WHEN ANY CHILLED WATER VALVE IS MORE THAN 95% OPEN, THE CHILLED WATER SYSTEM PRESSURE SETPOINT SHALL INCREASE BY 0.1 PSIG (ADJ.) OF THE CURRENT CHILLED WATER SYSTEM DIFFERENTIAL SETPOINT. THIS OCCURS EVERY 5 MINUTES UNTIL NO VALVE IS MORE THAN 95% OPEN, OR IF THE CHILLED WATER SYSTEM DIFFERENTIAL PRESSURE SETPOINT HAS RISEN TO THE SYSTEMS MAXIMUM SETTING, OR IF THE PUMP VARIABLE

FREQUENCY DRIVES ARE AT THE MAXIMUM SETTING (60 HZ).

LOW TEMPERATURE FREEZE PROTECTION: ENABLE PRIMARY CHILLED WATER PUMPS IF DISABLED AND OUTSIDE

AIR TEMPERATURE DROPS BELOW 38F 9ADJ.).
