BOILER AND BOILER FUEL SYSTEMS EMERGENCY STOP:

THE FOLLOWING SHALL BE PROVIDED BY AND COORDINATED BY THE TEMPERATURE

CONTROLS CONTRACTOR.

THE FOLLOWING SEQUENCE SHALL BE INITIATED UPON ACTIVATION OF MAIN BOILER PLANT

EMERGENCY STOP CONTROL SWITCHES TO BE LOCATED AT THE EGRESS DOORWAYS TO THE

MECH/BOILER ROOM PER CODE. THESE SWITCHES SHALL BE PUSH-PULL, MAINTAINED

CONTACT TYPE, WITH MUSHROOM HEADS, AS NORMALLY PROVIDED FOR THIS SERVICE.

UPON ACTIVATION OF THE E-STOP SWITCH, THE BOILERS SHALL BE COMMANDED OFF AND THE

DDC SHALL CONTINUE TO RUN THE ACTIVE PRIMARY AND SECONDARY HEATING PUMPS UNTIL

THE SECONDARY HEATING LOOP SUPPLY TEMPERATURE DROPS 20°F (ADJ) BELOW LOOP

TEMPERATURE SETPOINT IN ORDER TO DISSIPATE THE RESIDUAL HEAT IN THE FORMERLY

ACTIVE BOILERS AT WHICH POINT THE PUMPS WILL BE COMMANDED OFF.

POWERED OPEN/ NORMALLY CLOSED SAFETY SHUT-OFF SOLENOID VALVE LOCATED ON THE

MAIN NATURAL GAS BOILER FUEL SOURCE SHALL BE INTERLOCKED TO CLOSE WHEN THE

EMERGENCY STOP IS ACTIVATED.

PROVIDE AN INTERLOCK TO THE LOCAL FIRE ALARM SYSTEM PANEL IF PRESENT TO ACHIEVE THE

SAME SEQUENCE AS DESCRIBED ABOVE UPON FIRE ALARM STATUS. COORDINATE WITH THE

FIRE ALARM SYSTEM VENDOR/CONTRACTOR.

BOILERS & HEATING PUMPS:

BOILER SYSTEM RUN CONDITIONS:

THE BOILER SYSTEM SHALL BE ENABLED TO RUN WHENEVER:

· A DEFINABLE NUMBER OF HOT WATER COILS NEED HEATING.

· RUNS YEAR ROUND.

TO PREVENT SHORT CYCLING, THE BOILER SYSTEM SHALL RUN FOR AND BE OFF FOR MINIMUM ADJUSTABLE TIMES

(BOTH USER DEFINABLE), UNLESS SHUTDOWN ON SAFETIES OR OUTSIDE AIR CONDITIONS.

THE BOILER SHALL RUN SUBJECT TO ITS OWN INTERNAL SAFETIES AND CONTROLS.

THE BOILER SYSTEM SHALL ALSO RUN FOR FREEZE PROTECTION WHENEVER THE OUTSIDE AIR TEMPERATURE IS

LESS THAN 38°F (ADJ.).

ALARMS SHALL BE PROVIDED AS FOLLOWS:

· FAILURE: COMMANDED ON, BUT THE STATUS IS OFF.

· RUNNING IN HAND: COMMANDED OFF, BUT THE STATUS IS ON.

BOILER LEAD/LAG OPERATION:

THE BOILER OPERATING CONTROLLERS TO BE SET AT 190°F TO OPERATE AS A SECONDARY HIGH LIMIT.

THE TWO BOILERS SHALL OPERATE IN A LEAD/LAG FASHION ALONG WITH THEIR RESPECTIVE BOILER PUMPS.

· THE LEAD BOILER SHALL RUN FIRST.

· AS HOT WATER TEMPERATURE DROPS BELOW A LAG BOILER SETPOINT, THE LAG BOILER SHALL STAGE ON

AND RUN IN UNISON WITH THE LEAD BOILER TO MAINTAIN HOT WATER TEMPERATURE SETPOINT.

· AS HOT WATER TEMPERATURE DROPS BELOW A SECOND LAG BOILER SETPOINT (IF AVAILABLE), THE SECOND

LAG BOILER SHALL STAGE ON AND RUN IN UNISON WITH THE LEAD & LAG BOILER TO MAINTAIN HOT WATER

TEMPERATURE SETPOINT.

· AS HOT WATER TEMPERATURE RISES BACK TO 20°F (ADJ.) ABOVE SETPOINT, THE LAG BOILER SHALL STAGE

OFF.

· AS HOT WATER TEMPERATURE RISES BACK TO 10°F (ADJ.) ABOVE SETPOINT, THE LAG BOILER SHALL STAGE

OFF.

THE DESIGNATED LEAD BOILER SHALL ROTATE UPON ONE OF THE FOLLOWING CONDITIONS: (USER SELECTABLE):

· MANUALLY THROUGH A SOFTWARE SWITCH

· IF BOILER RUNTIME (ADJ.) IS EXCEEDED

· DAILY

· WEEKLY

· MONTHLY

ALARMS SHALL BE PROVIDED AS FOLLOWS:

· LOW WATER TEMPERATURE

· BOILER FAILURE

HOT WATER SUPPLY TEMPERATURE SETPOINT RESET: ( BY TWO METHODS)

1) THE HOT WATER SUPPLY TEMPERATURE SETPOINT SHALL RESET USING A TRIM AND

RESPOND ALGORITHM BASED ON HEATING REQUIREMENTS. AS THE FACILITY'S DEMAND FOR

HEATING GOES BEYOND A USER DEFINABLE AMOUNT OF REQUESTS, THE SETPOINT SHALL

RESET TO A HIGHER VALUE (ADJ.). ONCE THE HEATING REQUESTS ARE SATISFIED THE

SETPOINT SHALL GRADUALLY LOWER OVER TIME TO REDUCE HEATING ENERGY USE.

2) OUTSIDE AIR RESET. (USER SELECTABLE)

PRIMARY HOT WATER TEMPERATURE MONITORING:

THE FOLLOWING TEMPERATURES SHALL BE MONITORED:

· PRIMARY HOT WATER SUPPLY.

· PRIMARY HOT WATER RETURN.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

· HIGH PRIMARY HOT WATER SUPPLY TEMP: IF GREATER THAN 200°F (ADJ.).

· LOW PRIMARY HOT WATER SUPPLY TEMP: IF LESS THAN 130°F (ADJ.).

AHU COIL - HOT WATER LOOP:

HOT WATER VALVE:

THE HOT WATER VALVE SHALL MODULATE TO MAINTAIN THE DISCHARGE AIR SETPOINT AS

MEASURED BY THE TEMPERATURE SENSOR.

HP-170-3

HP-170-1

SECONDARY HOT WATER PUMPS(RADIATION LOOP(CP-18-1 & CP-18-1A)

HOT WATER PUMPS: THE HOT WATER PUMPS ARE VARIABLE SPEED PUMPS. EACH PUMP MAY BE

STARTED AND STOPPED MANUALLY AT ITS ASSOCIATED MOTOR STARTER BY PLACING THE

HAND-OFF-AUTO SWITCH IN THE HAND POSITION. EACH PUMP MAY ALSO BE STARTED AND STOPPED

AUTOMATICALLY BY THE DDC SYSTEM WHEN THE HAND-OFF-AUTO SWITCH IS IN THE AUTO

POSITION.

ONE HOT WATER PUMP SHALL OPERATE CONTINUOUSLY. THE PUMPS SHALL OPERATE IN A

LEAD-LAG MANNER AS PROGRAMMED THROUGH THE DDC SYSTEM TO ENSURE EQUAL RUN-TIME ON

EACH PUMP. STATUS OF EACH PUMP SHALL BE MONITORED BY THE DDC SYSTEM THROUGH EACH

PUMPS ASSOCIATED CURRENT SENSOR. IF THE OPERATING PUMP SHOULD FAIL AS INDICATED BY

THE CURRENT SENSOR, THE DDC SYSTEM WILL ISSUE A STOP COMMAND TO THAT PUMP AND A

START COMMAND TO THE PUMP ACTING AS STAND-BY. THE DDC SYSTEM WILL ALSO INITIATE A

PUMP FAILURE ALARM. LEAD PUMP SHALL MODULATE TO MAINTAIN A DIFFERENTIAL PRESSURE

SETPOINT OF 7 PSI ( ADJUSTABLE)
