HOT WATER HEATING SYSTEM - ONE (1) STEAM TO HOT WATER HEAT EXCHANGER
1. GENERAL:
1.1. THE HOT WATER SYSTEM SHALL BE ENABLED YEAR ROUND. STEAM SHALL BE MADE
AVAILABLE TO THE BUILDING YEAR ROUND.
2. PUMP OPERATION (HWP-1,2):
2.1. THE PUMPS SHALL ALTERNATE FOR LEAD/LAG OPERATION TO EQUALIZE RUNTIMES.
2.2. ON A CALL FOR HOT WATER, THE BAS SHALL OPEN THE HOT WATER ISOLATION VALVE
FOR THE HEAT EXCHANGER.
2.3. UPON CONFIRMATION OF VALVE OPENING (VIA AN END SWITCH) THE BAS WILL START
THE LEAD PUMP.
2.4. IF THE LEAD PUMP FAILS TO START, THE BAS WILL GENERATE AN ALARM AND START
THE LAG PUMP.
2.5. IF THE LAG PUMP FAILS TO START, THE BAS WILL GENERATE AN ALARM.
2.6. THE LEAD PUMP SHALL OPERATE TO MAINTAIN 10 PSIG DIFFERENTIAL PRESSURE AT
THE END OF THE PIPING SYSTEM.THE OPERATING PUMP SHALL MAINTAIN A 35% FLOW
RATE AS A MINIMUM.
2.7. WHEN THE SPEED OF THE LEAD PUMP REACHES 80% (ADJ) AND AFTER AN
ADJUSTABLE DELAY, THE BAS SHALL START THE LAG PUMP AND SLOWLY INCREASE
THE LAG PUMP SPEED, WHILE SIMULTANEOUSLY DECREASING THE SPEED OF THE
LEAD PUMP, UNTIL THE PUMPS ARE RUNNING AT THE SAME SPEED.
2.8. HE BAS WILL MODULATE BOTH PUMPS AT THE SAME SPEED TO MAINTAIN THE
REQUIRED DIFFERENTIAL PRESSURE.
2.9. WHEN THE SPEED OF THE PUMPS DROPS TO 30% (ADJ) AND AFTER AN ADJUSTABLE
DELAY, THE BAS WILL SHUT THE LEAD PUMP DOWN AND INCREASE THE SPEED OF
THE LAG PUMP TO MEET THE DIFFERENTIAL PRESSURE REQUIREMENT. THE LAG
PUMP NOW BECOMES THE LEAD PUMP TO EQUALIZE RUN TIMES.
3. STEAM-TO-HOT WATER HEAT EXCHANGER (CONV-1):
3.1. UPON PROOF OF FLOW FROM A CURRENT SWITCH ON THE OPERATING PUMP, THE
BAS SHALL MODULATE OPEN THE STEAM CONTROL VALVE ON THE HEAT EXCHANGER.
3.2. THE BAS SHALL MODULATE THE STEAM VALVE AS REQUIRED TO MAINTAIN 180ºF
LEAVING WATER.
4. SHUTDOWN:
4.1. WHEN THE HEAT EXCHANGER IS SHUTDOWN BY EITHER A STOP COMMAND OR A
SYSTEM SAFETY, THE UNIT WILL BE SET AS FOLLOWS:
4.1.1. THE STEAM CONTROL VALVE WILL CLOSE.
4.1.2.THE HOT WATER CONTROL VALVE WILL BE FULLY OPENED.
4.1.3.THE HOT WATER PUMPS WILL BE INDEXED OFF.
5. THE EMCS GRAPHICS SHALL BE MODIFIED TO SHOW THE STEAM TO HOT WATER HEAT
EXCHANGER, WITH STEAM FLOW, STEAM FLOW RATE, STEAM PRESSURE, STEAM
TEMPERATURE AND HOT WATER SUPPLY/RETURN TEMPERATURES.
6. IN ADDITION TO THE SEQUENCE NOTED ABOVE THE BAS SHALL MONITOR THE FOLLOWING
DIGITAL AND ANALOG INPUT POINTS:
6.1. GPM FLOW THROUGH THE HOT WATER SYSTEM BY MEANS OF AN ELECTRONIC FLOW
METER
6.2. HOT WATER SUPPLY AND RETURN TEMPERATURES
6.3. PUMP COMMAND AND STATUS
6.4. OUTDOOR AIR TEMPERATURE AND HUMIDITY
6.5. PUMP VFD FREQUENCY
7. THE BAS SHALL GENERATE AN ALARM UPON:
7.1. VARIABLE FREQUENCY DRIVE FAULTS
7.2. PUMP FAULTS
7.3. SYSTEM TEMPERATURES OUT OF RANGE
8. ALL HOT WATER VALVES SHALL BE NORMALLY OPEN AT ALL FAN COIL UNITS AND AIR
HANDLERS.

C. THE BUILDING FIRE ALARM SYSTEM SHALL PROVIDE ONE DIGITAL OUTPUT TO THE BAS TO INDICATE ALARM CONDITION. WIRING FOR THIS ALARM POINT SHALL BE PROVIDED BY THE BAS SUBCONTRACTOR. UPON RECEIPT OF THIS ALARM, THE BAS SHALL SHUT
DOWN ALL AIR MOVING EQUIPMENT IN THE BUILDING.
7. HUMIDITY CONTROL: UPON A RISE IN HUMIDITY LEVEL ABOVE 65% R.H., AS SENSED BY THE RETURN DUCT HUMIDITY SENSOR, THE DX COMPRESSORS SHALL BE INDEXED TO 100% BY THE BAS AND ALL VAV BOX HEATING COILS SHALL BE MODULATED TO MAINTAIN
SPACE TEMPERATURE 1° F LOWER THAN THE COOLING SETPOINT.
8. FILTER BANKS: PROVIDE PRESSURE DIFFERENTIAL SWITCHES ACROSS ALL FILTER BANKS AND INDICATE DIRTY FILTER STATUS
BASED ON MANUFACTURERS FILTER PRESSURE DROP DATA.
B. UNOCCUPIED MODE:
1. WHEN THE TEMPERATURE DROPS BELOW THE UNOCCUPIED LOW LIMIT SETPOINT OR RISES ABOVE THE UNOCCUPIED HIGH LIMIT OR IF TWO OR MORE ZONES HAVE FALLEN BELOW 50°F, THE UNIT SHALL OPERATE IN PREPARATORY MODE.
2. WHEN THE UNIT IS DISABLED, THE SUPPLY FAN SHALL RAMP DOWN AND TURN OFF. THE DX COMPRESSORS ARE INDEXED OFF.
THE STEAM HEATING COIL CONTROL VALVE IS CLOSED. THE OUTDOOR AIR DAMPER IS CLOSED. THE RETURN AIR DAMPER IS OPEN.

VAV TERMINAL UNITS (VAV-)
A. THE VARIABLE VOLUME (VAV) TERMINAL UNIT WILL BE CONTROLLED INDEPENDENT OF SYSTEM PRESSURE FLUCTUATIONS BY AN
APPLICATION SPECIFIC DDC CONTROLLER UTILIZING ELECTRIC ACTUATION.
B. OCCUPIED AND UNOCCUPIED OPERATIONS ARE THE SAME.
C. THE TERMINAL UNIT SHALL OPERATE WITH A MINIMUM COOLING AIRFLOW, MINIMUM HEATING AIRFLOW AND MAXIMUM AIRFLOW. IF THE AHU SUPPLY TEMPERATURE IS BELOW 65° F THE TERMINAL UNIT DAMPER MODULATES BETWEEN MAXIMUM AND MINIMUM COOLING AIRFLOWS TO MAINTAIN SPACE TEMPERATURE AT COOLING SETPOINT. IF THE TERMINAL UNIT IS AT MINIMUM AIRFLOW AND THE SPACE TEMPERATURE CONTINUES TO DROP THE TERMINAL UNIT DAMPER POSITIONS TO PROVIDE MINIMUM HEATING AIRFLOW AND HEATING COIL CONTROL VALVE MODULATES TO MAINTAIN SPACE TEMPERATURE AT HEATING SETPOINT. IF THE AHU SUPPLY TEMPERATURE IS ABOVE 65° F THE TERMINAL UNIT DAMPER MODULATES BETWEEN MAXIMUM AND MINIMUM HEATING AIRFLOW, AND THE UNIT REHEAT
VALVE IS MODULATED TO MAINTAIN SPACE TEMPERATURE AT HEATING SETPOINT.
D. TEMPERATURE SENSORS LOCATED IN PUBLIC AREAS SUCH AS CORRIDORS SHALL HAVE NO SET POINT ADJUSTMENT CAPABILITY AT THE WALL MOUNTED SENSORS. ALL OTHER TEMPERATURE SENSORS SHALL BE PROVIDED WITH LIMITED MANUAL SET POINT ADJUSTMENT AT THE WALL MOUNTED TEMPERATURE SENSOR AND WITH AN OVERRIDE BUTTON TO ENABLE THE RESPECTIVE AIR HANDLER, THE CHILLER
PLANT AND THE BOILER PLANT TO PROVIDE HEATING OR COOLING AS REQUIRED.
