HOT WATER DISTRIBUTION PUMP START/STOP:

THE SYSTEM SHALL START A HOT WATER PUMP THROUGH A CONTACT CLOSURE OF

THE PUMP'S MOTOR STARTER ENABLE CONTACTS.

HOT WATER DISTRIBUTION PUMP STATUS:

THE SYSTEM SHALL DETECT HOT WATER PUMP RUN STATUS BY A CURRENT SWITCH.

HOT WATER DISTRIBUTION PUMP LEAD/LAG:

THE HOT WATER PUMP LEAD/LAG SEQUENCE SHALL BE BASED ON A WEEKLY

SCHEDULE. FROM THE BAS CONTROLLER OR A BAS WORKSTATION, AN OPERATOR

SHALL BE ABLE TO MANUALLY CHANGE THE LEAD/LAG SEQUENCE.

HOT WATER DISTRIBUTION PUMP START/STOP:

THE SYSTEM SHALL START A HOT WATER PUMP THROUGH A CONTACT CLOSURE OF

THE PUMP'S VARIABLE FREQUENCY DRIVE (VARIABLE SPEED DRIVE) RUN-ENABLE

CONTACTS.

HOT WATER DISTRIBUTION PUMP STATUS:

THE SYSTEM SHALL DETECT HOT WATER PUMP RUN STATUS BY A VARIABLE SPEED

DRIVE CURRENT SWITCH.

HOT WATER DISTRIBUTION PUMP LEAD/LAG:

THE HOT WATER PUMP LEAD/LAG SEQUENCE SHALL BE BASED ON A WEEKLY

SCHEDULE. FROM THE BAS CONTROLLER OR A BAS WORKSTATION, AN OPERATOR

SHALL BE ABLE TO MANUALLY CHANGE THE LEAD/LAG SEQUENCE.

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 SYSTEM SHALL ANNUNCIATE A HOT

WATER PUMP FAILURE ALARM TO THE BAS AND START THE LAG.

HOT WATER DISTRIBUTION PUMP SPEED:

WHEN THE SYSTEM SHALL MONITOR THE HOT WATER SYSTEM DIFFERENTIAL

PRESSURE SENSOR. WHEN THE PUMP VARIABLE SPEED DRIVE IS ENABLED, THE

SYSTEM SHALL CONTROL THE ANALOG SPEED SIGNAL SENT TO THE PUMP VARIABLE

SPEED DRIVE TO MAINTAIN A HOT WATER DIFFERENTIAL PRESSURE SETPOINT OF 5.0

PSID (ADJ.).

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.

IN THE EVENT THAT A HYDRONIC AIRSIDE TYPE EQUIPMENT INITIATES A LOW LIMIT

ALARM, THE HEATING SYSTEM SHALL ENABLE, IF DISABLED, AND PROVIDE HEATING

MEDIUM CIRCULATION TO THE EQUIPMENT.

CARBON MONOXIDE DETECTOR:

THE CARBON MONOXIDE DETECTOR SHALL MONITOR THE BOILER ROOM FOR HIGH

LEVELS OF CO. IF THE CO LEVEL RISES ABOVE 50 PPM (ADJ.), THEN AN ALARM SHALL

BE SIGNALED TO THE HEATING SYSTEM CONTROLLER OR BAS WORKSTATION.

BOILER EMERGENCY SHUTDOWN SWITCH:

IF THE BOILER EMERGENCY SHUTDOWN SWITCH HAS BEEN ACTIVATED, THE BOILERS

ARE TO SHUT DOWN IMMEDIATELY AND AN ALARM SHALL BE SIGNALED TO THE BAS

WORKSTATION.

SEQUENCE OF OPERATION: HEATING PLANT SYSTEM

SYSTEM GENERAL DESCRIPTION:

THE HEATING PLANT SYSTEM CONTROLLER PROVIDES STAND-ALONE CONTROL FROM

AN OPTIONAL HIGHER LEVEL BUILDING AUTOMATION SYSTEM (BAS). THE HEATING

PLANT CONTROL SYSTEM SHALL MONITOR AND CONTROL THE SYSTEM'S BOILER(S),

PUMP(S), AND CONTROL VALVES AS SHOWN ON THE HEATING PLANT FLOW DIAGRAM,

IN THE HEATING PLANT POINTS LIST AND AS DETAILED IN THE SEQUENCE OF

OPERATION LISTED BELOW.

THE HEATING PLANT SYSTEM CONSISTS OF HOT WATER BOILER(S) WITH ITS PIPING

CONFIGURATION ARRANGED AS A PRIMARY / SECONDARY LOOP SUPPLYING HOT

WATER TO THE FACILITY.

THE MANIFOLDED HOT WATER DISTRIBUTION PUMPS ARE CONFIGURED AS LEAD / LAG

CONTROL. THE FACTORY BOILER SYSTEM CONTROLLER SHALL PROVIDE

STAND-ALONE CONTROL OR BAS WORKSTATION CONTROL OF THE SUPPLY HEATING

WATER TEMPERATURE SETPOINT (ADJ.).

HEATING SYSTEM ENABLE/DISABLE:

THE HEATING SYSTEM SHALL BE ENABLED/DISABLED BY THE HEATING PLANT

CONTROLLER AS REQUESTED BY THE BUILDING AUTOMATION SYSTEM (BAS)

HUMAN-INTERFACE PANEL OR THE BAS TIME OF DAY SCHEDULE. WHEN ENABLED,

THE SYSTEM SHALL ENABLE THE LEAD BOILER, THE ASSOCIATED PRIMARY BOILER

PUMP AND ENABLE THE LEAD SECONDARY PUMP. THE HEATING PLANT IS DISABLED

WHEN ALL BOILERS ARE DISABLED AND THERE IS NOT AN ACTIVE HOT WATER

DISTRIBUTION PUMP REQUEST. WHEN THE PLANT IS DISABLED THE HOT WATER PUMP

SHALL BE COMMANDED OFF.

HOT WATER RESET:

THE HOT WATER SUPPLY TEMPERATURE SETPOINT SHALL BE LINEARLY RESET FROM

120.0 DEG. F (ADJ.) TO 180.0 DEF. F (ADJ.) AS THE OUTSIDE AIR TEMPERATURE FALLS

FORM 60.0 DEG. F (ADJ.) TO 0.0 DEG. F (ADJ.)

BOILER CONTROL:

THE BOILER LEAD/LAG SEQUENCE SHALL BE BASED ON A WEEKLY SCHEDULE. FROM

THE SYSTEM CONTROLLER OR A BAS WORKSTATION, AN OPERATOR SHALL BE ABLE

TO MANUALLY CHANGE THE LEAD/LAG SEQUENCE.

BOILER CONTROLS SHALL BE PROVIDED BY THE MANUFACTURER BOILER

SEQUENCER AND SHALL TIE TO THE…
