SEQUENCE OF OPERATION: HEATING PLANT SYSTEM - VARIABLE-PRIMARY

SYSTEM GENERAL DESCRIPTION:

THE HEATING PLANT SYSTEM CONTROLLER PROVIDES STAND-ALONE

CONTROL OR CONTROL FROM AN OPTIONAL HIGHER LEVEL BUILDING

AUTOMATION SYSTEM (BAS) .

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

ITS PIPING CONFIGURATION ARRANGED AS A VARIABLE PRIMARY 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 BY THE BAS WHEN THE

OUTSIDE AIR TEMPERATURE FALLS BELOW 60.0 DEG (ADJ.). 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 AND THE

BOILER ISOLATION VALVES SHALL BE CLOSED.

HOT WATER RESET:

THE BAS SHALL MONITOR THE HOT WATER SUPPLY TEMPERATURE

SETPOINT AND LINEARLY RESET FROM 120.0 DEG. F (ADJ.) TO 180.0 DEG. F

(ADJ.) AS THE OUTSIDE AIR TEMPERATURE FALLS FROM 60.0 DEG. F (ADJ.)

TO 0.0 DEG. F (ADJ.)

BOILER CONTROL:

THE BOILERS SHALL BE CONTROLLED BY THE MANUFACTURER BOILER

SEQUENCE VIA SIGNAL FROM THE LEAD BOILER. THE LEAD BOILER SHALL

BE ROTATED ON A WEEKLY BASIS.

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 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

WORKSTATION AND START 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 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.).

LEAD/LAG: IF THE LEAD PUMP SPEED FALLS BELOW 65% (ADJ.) FOR MORE

THAN 5 MINUTES (ADJ.) THE LAST OPERATING PUMP IN THE SEQUENCE

SHALL BE DISABLED.

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 VARIABLE SPEED DRIVE'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 VARIABLE SPEED DRIVE'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.

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 HEATING SYSTEM CONTROLLER OR BAS WORKSTATION.
