SEQUENCE OF OPERATION

DESCRIPTION: THE HEATING SYSTEM CONSISTS OF ONE ELECTRIC BOILER, TWO SECONDARY PUMPS WITH VFDS AND TWO PERIMETER HEAT CONTROL VALVES THAT SERVE THE BUILDINGS PERIMETER HEATING SYSTEM AS WELL AS THE AIR HANDLING UNIT HEATING COIL.

BOILER CONTROL:

• SENSE HEATING WATER SUPPLY TEMPERATURE IN THE COMMON SUPPLY PIPING BETWEEN THE BOILER AND THE PUMPS. SENSE THE HEATING WATER RETURN TEMPERATURE

IN THE COMMON RETURN PIPING BEFORE THE BOILER. TEMPERATURE SENSORS IN THE COMMON PIPING SHALL BE INDEPENDENT OF THE BOILER SYSTEM CONTROLS.

• WIRE AND INSTALL HEATING WATER SUPPLY AND RETURN TEMPERATURE SENSORS FOR THE BOILER SYSTEM CONTROLS.

• THE DDC SYSTEM SHALL START THE BOILER SYSTEM WHEN THE OUTSIDE AIR TEMPERATURE IS BELOW 70 DEGREES F (ADJUSTABLE) AND THERE IS A CALL FOR HEAT FROM

THE AHU-1 CONTROLLER.

• THE BOILER SYSTEM CONTROLS SHALL BE ENABLED AND MODULATE THE BOILER AS REQUIRED TO MAINTAIN THE HEATING WATER SUPPLY TEMPERATURE SETPOINT. THE DDC

SYSTEM SHALL MONITOR BOILER STATUS AND BOILER RUNTIME.

• PROVIDE INTERLOCK WIRING BETWEEN BOILER AND ASSOCIATED LEAD PUMP SO THE PUMP RUNS CONTINUOUSLY WHEN THE BOILER IS ENABLED. INTERLOCK WIRING SHALL

BE INDEPENDENT OF THE BMS. PROVIDE A CURRENT STATUS SWITCH FOR PUMP TO PROVE OPERATION. IF THE CURRENT STATUS SWITCH DOES NOT PROVE OPERATION, SEND

AN ALARM TO THE OPERATOR INTERFACE.

• THE TEMPERATURE OF THE HEATING WATER SUPPLY SHALL BE CONTROLLED TO MAINTAIN A SETPOINT AS DETERMINED BY THE OUTDOOR AIR DRY BULB TEMPERATURE. THE SETPOINT SHALL CORRESPOND LINEARLY BASED ON THE FOLLOWING CORRESPONDING POINTS (SCHEDULE SETPOINTS SHALL BE ADJUSTABLE):

OAT HWS TEMPERATURE

60°F 120°F 10°F 160°F

HEATING WATER PUMP CONTROL:

• THE DIRECT DIGITAL CONTROL (DDC) SYSTEM SHALL START THE LEAD PUMP VIA THE VFD AND SHALL RUN CONTINUOUSLY WHEN THE BOILER PLANT IS ENABLED. THE LAG

PUMP SHALL REMAIN OFF.

• IN CASE OF VFD FAULT DETECTION, THE DDC SYSTEM SHALL WAIT 30 SECONDS (ADJUSTABLE.) AND THEN CALL THE VFD TO START. IF THE VFD DOES NOT START, THE DDC

SYSTEM SHALL CALL A SECOND TIME. IF THE VFD STILL HAS NOT STARTED, AN ALARM SHALL BE SENT TO THE OPERATOR INTERFACE.

• INSTALL A CURRENT STATUS SWITCH TO PROVE LEAD AND LAG PUMP OPERATION. LOCATE SWITCHES SO THEY SENSE PUMP STATUS WHEN OPERATED BY THE VFD. IF THE

LEAD PUMP CURRENT STATUS SWITCH DOES NOT PROVE OPERATION, AN ALARM SHALL BE SENT TO THE OPERATOR INTERFACE AND THE DDC SYSTEM SHALL START THE LAG PUMP VIA THE VFD. IF THE LAG PUMP CURRENT STATUS SWITCH DOES NOT PROVE OPERATION, A SECOND ALARM SHALL BE SENT TO THE OPERATOR INTERFACE. THE SEQUENCE SHALL BE REPEATED TWICE. IF SYSTEM DOES NOT PROVE OPERATION, THE LAG PUMP SHALL REMAIN ON.

• THE DDC SYSTEM SHALL CONTROL THE OPERATING PUMP VFD FROM THE DIFFERENTIAL PRESSURE. INITIAL SETPOINT SHALL BE 5 PSIG (ADJUSTABLE). FINAL SETPOINT SHALL

BE OPTIMIZED BY THE BALANCING CONTRACTOR.

• THE DDC SYSTEM SHALL ALTERNATE THE LEAD/LAG STATUS OF THE PUMPS ON A WEEKLY (ADJUSTABLE) BASIS.

BUILDING 6 AHU-1 HEATING HOT WATER COIL AND HUMIDIFIER CONTROL

• ADD THE FOLLOWING CONTROL SEQUENCES TO AHU-1 CONTROL:

• ON A CALL FOR HEATING FROM THE EXISTING AHU-1 DDC CONTROLLER, THE HEATING HOT WATER THREE-WAY VALVE SHALL MODULATE OPEN TO MEET SETPOINT.

• PROVIDE A HUMIDITY SENSOR IN THE RETURN DUCT OF AHU-1, WHEN RETURN HUMIDITY DROPS BELOW 25% SEND A SIGNAL TO THE NEW HUMIDIFICATION STEAM GENERATOR CONTROLLER TO INITIATE STEAM GENERATION. THE STEAM GENERATOR WILL MODULATE TO MAINTAIN RETURN RELATIVE HUMIDITY AT 30%. PROVIDE A HUMIDITY SENSOR IN THE DOWNSTREAM DUCTWORK THE DDC SYSTEM SHALL OVERRIDE THE SIGNAL TO THE HUMIDIFIER CONTROL VALVE TO LIMIT THE SUPPLY AIR RELATIVE HUMIDITY TO 70% (ADJUSTABLE). IF THE SUPPLY AIR RELATIVE HUMIDITY EXCEEDS 75% (ADJUSTABLE) THE STEAM GENERATOR SHALL STOP AND AN ALARM SHALL BE SENT TO THE ENERGY COMMAND CENTER. WHENEVER THE OUTDOOR AIR TEMPERATURE IS ABOVE 40 DEGREES F(ADJUSTABLE), THE DDC SYSTEM SHALL SEND A SIGNAL TO THE STEAM

GENERATOR TO BE OFF.

FLOW METER:

• INSTALL FLOW METER AS INDICATED.

• FLOW METER SHALL MONITOR FLOW RATE TO TRACK PEAK MBH CONSUMPTION AND TOTALIZE BUILDING BTU CONSUMPTION.

GENERAL NOTES

1. SERVICE DISCONNECT PROVIDED AND INSTALLED BY ELECTRICAL CONTRACTOR SHALL BE LOCATED WITHIN 6 FEET OF CONTROLLER.

2. CONTROLLER SHALL HAVE A MINIMUM SERVICE CLEARANCE OF 36 INCHES.
