SEQUENCE OF OPERATION - BOILER PLANT

GENERAL DESCRIPTION:

THE HOT WATER SYSTEM CONSISTS OF MULTIPLE BOILERS AND ASSOCIATED PUMPS. THE BUILDING AUTOMATION SYSTEM (BAS) CONTROLLER SHALL PROVIDE STAND-ALONE CONTROL OR BAS WORKSTATION CONTROL OF THE SUPPLY HEATING WATER TEMPERATURE SETPOINT (ADJ.) BY CONTROLLING THE BOILER'S ENABLE/DISABLE BOILER SIGNAL. THE BAS CONTROLLER SHALL BE EQUIPPED WITH A HUMAN-INTERFACE PANEL THAT SHALL BE PASSWORD PROTECTED TO PREVENT UNAUTHORIZED ACCESS.

HEATING SYSTEM ENABLE/DISABLE:

THE HEATING SYSTEM SHALL BE ENABLED 24/7/365. WHEN ENABLED, THE BAS CONTROLLER SHALL START THE LEAD HOT WATER DISTRIBUTION PUMP, THE LEAD BOILER CIRCULATING PUMP, AND ENABLE THE LEAD BOILER. THE BOILER FACTORY CONTROL SHALL

OPERATE THE BOILER TO MAINTAIN ITS LOCAL SUPPLY SETPOINT.

BOILER CONTROL:

THE BOILER LEAD/LAG SEQUENCE 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 HOT WATER DISTRIBUTION SYSTEM SUPPLY TEMPERATURE FALLS MORE THAN 15.0 DEG. F (ADJ.) BELOW SETPOINT FOR A PERIOD LONGER THAN 15 MINUTES (ADJ.), OR IF AN ACTIVE BOILER SIGNALS A FAILURE ALARM, THE BAS CONTROLLER SHALL ENABLE THE LAG BOILER. IN ADDITION, THE BAS CONTROLLER SHALL SEND AN ALARM TO THE BAS WORKSTATION. WHEN A BOILER FAILURE EXISTS, LEAD/LAG AUTOMATION SHALL BE DISABLED AND THE CURRENTLY RUNNING BOILER SHALL BECOME THE LEAD BOILER. ONCE THE PROBLEM IS 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.

ONCE THE LEAD BOILER IS ENABLED, THE ADD SEQUENCE OF ADDITIONAL BOILERS SHALL BE DISABLED FOR A PERIOD OF 30 MINUTES (ADJ.). ADDITIONAL BOILERS ARE ADDED IF THE HOT WATER DISTRIBUTION SYSTEM SUPPLY TEMPERATURE FALLS 5.0 DEG. F (ADJ.) BELOW

THE HOT WATER SETPOINT FOR A PERIOD OF 10 MINUTES (ADJ.) OR MORE.

THE LAST BOILER ENABLED SHALL BE DISABLED WHEN THE HOT WATER TEMPERATURE RISES 5.0 DEG. F (ADJ.) ABOVE THE HOT WATER SETPOINT FOR A PERIOD OF 10 MINUTES (ADJ.) OR MORE. ADDITIONAL BOILERS SHALL BE DISABLED FOLLOWING THE SAME SUBTRACTION SEQUENCE IF THE HOT WATER TEMPERATURE REMAINS 5.0 DEG. F (ADJ.) ABOVE THE HOT WATER SETPOINT FOR A PERIOD OF 10 MINUTES

(ADJ.) OR MORE.

HOT WATER RESET:

THE HOT WATER SUPPLY TEMPERATURE SETPOINT SHALL BE LINEARLY RESET FROM 100.0 DEG. F (ADJ.) TO 130.0 DEG. F (ADJ.) AS THE

OUTSIDE AIR TEMPERATURE FALLS FROM 60.0 DEG. F (ADJ.) TO 30.0 DEG. F (ADJ.)

HOT WATER DISTRIBUTION PUMP START/STOP:

THE BAS CONTROLLER SHALL START A HOT WATER PUMP THROUGH A CONTACT CLOSURE OF THE PUMP'S VARIABLE FREQUENCY DRIVE

(VFD) RUN-ENABLE CONTACTS.

HOT WATER DISTRIBUTION PUMP STATUS:

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

HOT WATER DISTRIBUTION PUMP LEAD/LAG:

THE HOT WATER PUMP LEAD/LAG SEQUENCE 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 LEAD PUMP SPEED FALLS BELOW 40% (ADJ.) FOR FIVE MINUTES (ADJ.) THE LAG PUMP SHALL BE DISABLED.

HOT WATER DISTRIBUTION 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 HOT WATER PUMP FAILURE ALARM TO THE BAS WORKSTATION AND STARTS THE LAG PUMP. WHEN A 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 ACTION SHALL RE-ENABLE THE LEAD/LAG SEQUENCE.

HOT WATER DISTRIBUTION PUMP SPEED:

THE BAS CONTROLLER SHALL MONITOR THE HOT WATER SYSTEM DIFFERENTIAL PRESSURE SENSOR. WHEN THE PUMP VFD IS ENABLED, THE BAS CONTROLLER SHALL CONTROL THE ANALOG SPEED SIGNAL SENT TO THE PUMP VFD TO MAINTAIN A HOT WATER DIFFERENTIAL

PRESSURE SETPOINT OF 50.0 PSIG (ADJ.).

PUMP OPTIMIZATION:

THE BAS SHALL CONTINUALLY MONITOR THE HOT WATER CONTROL VALVE POSITION OF ALL AHU'S IN THE HOT WATER SYSTEM.

AT HOT WATER SYSTEM STARTUP, THE HOT WATER PRESSURE SETPOINT IS 100% OF THE MAXIMUM PRESSURE SETPOINT. WHEN ALL HOT WATER VALVES ARE LESS THAN 85% OPEN, THE HOT WATER DIFFERENTIAL PRESSURE SETPOINT SHALL BE LOWERED BY 0.1 PSIG (ADJ.) OF THE CURRENT HOT WATER 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 HOT WATER DIFFERENTIAL PRESSURE SETPOINT, OR IF THE PUMP VFD'S

ARE AT A MINIMUM SPEED SETTING (22 HZ).

WHEN ANY HOT WATER VALVE IS MORE THAN 95% OPEN, THE HOT WATER PRESSURE SETPOINT SHALL INCREASES BY 0.1 PSIG (ADJ.) OF THE CURRENT HOT WATER DIFFERENTIAL SETPOINT. THIS OCCURS EVERY 5 MINUTES UNTIL NO VALVE IS MORE THAN 95% OPEN, OR IF THE HOT WATER DIFFERENTIAL PRESSURE SETPOINT HAS RISEN TO THE SYSTEM'S MAXIMUM SETTING, OR IF THE PUMP VFD'S ARE AT THE

MAXIMUM SETTING (60 HZ).

FREEZE PROTECTION:

WHEN THE OUTDOOR AIR TEMPERATURE FALLS BELOW 35.0 DEG. F (ADJ.), THE HOT WATER DISTRIBUTION PUMP SHALL OPERATE CONTINUOUSLY TO PROVIDE HOT WATER CIRCULATION TO ALL ASSOCIATED HOT WATER COILS. IF THE HOT WATER SUPPLY TEMPERATURE FALLS BELOW 130.0 DEG. F (ADJ.) DURING UNOCCUPIED PERIODS, THE BOILER SEQUENCE SHALL BE ENABLED TO SAFEGUARD AGAINST

LOW WATER TEMPERATURE AND BOILER CONDENSATION.

HOT WATER ENERGY

HOT WATER-COOLING DEMAND - ENERGY METER:

THE CONTROLLER SHALL MONITOR THE HOT WATER SUPPLY TEMPERATURE, HOT WATER RETURN TEMPERATURE AND HOT WATER FLOW TO THE BUILDING AND CALCULATE CURRENT ENERGY DEMAND ON A CONTINUAL BASIS. THESE VALUES SHALL BE MADE AVAILABLE TO

THE SYSTEM AT ALL TIMES.

ALARM SHALL BE GENERATED AS FOLLOWS:

• INVALID READING: SENSOR READINGS INDICATE AN INVALID DEMAND VALUE.

PEAK DEMAND HISTORY:

THE CONTROLLER SHALL MONITOR AND RECORD THE PEAK (HIGH AND LOW) DEMAND READINGS FROM THE HOT WATER ENERGY METER. PEAK READINGS SHALL BE RECORDED ON A DAILY, MONTH-TO-DATE, AND YEAR-TO-DATE BASIS.

USAGE HISTORY:

THE CONTROLLER SHALL MONITOR AND RECORD HOT WATER ENERGY METER READINGS SO AS TO PROVIDE AN ENERGY CONSUMPTION HISTORY. USAGE READINGS SHALL BE RECORDED ON A DAILY, MONTH-TO-DATE, AND YEAR-TO-DATE BASIS.
