NTS2 MAKEUP AIR UNIT SCHEMATIC

NTS4 BOILER ROOM VENTILATION SCHEMATIC

MAKE UP AIR UNIT SEQUENCE OF OPERATION:

GENERAL: MAKE-UP AIR UNIT PROVIDES COMBUSTION AIR FOR THE BOILERS.

SYSTEM CONTROL: ON A CALL FOR COMBUSTION AIR FROM THE BOILER CONTROL SYSTEM, COMBUSTION AIR DAMPER (D-2) SHALL OPEN AND PROVE OPEN POSITION WITH ACTUATOR END SWITCH. PROVIDE SEPARATE PROVING (AUXILARY) DEVICES AND CONNECTIONS DEDICATED ON DAMPERS AND FAN FOR BOILER SYSTEM INTERLOCKS SEPARATE FROM HVAC (BMS) CONTROLS.

THE MAKE UP AIR UNIT FAN SHALL START AND CONFIRM OPERATION BEFORE LEAD BOILER IS ENABLED TO START. ON A CALL FROM THE BOILER CONTROL INTERLOCK TO COMMAND THE SECOND MAKE UP AIR UNIT, THE UNIT SHALL START AND CONFIRM OPERATION BEFORE ENABLING THE BOILER. UPON COMMAND, THE MAKE UP AIR UNIT SHALL START THE SUPPLY FAN.

WHEN OUTSIDE TEMPERATURE IS BELOW SUPPLY AIR TEMPERATURE SETPOINT THE HOT WATER COIL VALVE (V-1) SHALL BE OPEN AND FACE AND BYPASS DAMPER (D-1) SHALL BE MODULATED TO MAINTAIN A MINIMUM SUPPLY AIR TEMPERATURE (T-1) OF

65°F (ADJ.). THE SETPONT SHALL BE ADJUSTABLE FROM THE BMS.

BOILER CONTROL SYSTEM SHALL PROVIDE MODULATING SUPPLY FAN VFD SPEED SIGNAL TO MAKE-UP AIR UNIT CONTROLLER TO MATCH BOILER FIRING RATE. SUPPLY FAN VFD SHALL PROVIDE MOTOR SPEED (RPM) AND ORIENTATION TO THE BOILER CONTROL

SYSTEM.

ALARMS: COMBUSTION AIR INTAKE DAMPER END SWITCH SHALL CONFIRM DAMPER OPEN OPPOSITION AND GENERATE ALARM THROUGH BMS AND BOILER CONTROSL IF OPEN POSITION HAS NOT BEEN REACH AFTER 45 SEC. (ADJ) AFTER REQUEST. FAN MOTOR CURRENT SENSOR SHALL DETECT FAN FAILURE AND REPORT ALARM TO BMS AND BOILER CONTROL SYSTEM. MAKE UP AIR UNIT SHALL BE SET IN ALARM IF SUPPLY AIR TEMPERATURE DROPS BELOW SETPOINT FOR 8 MIN. (ADJ.). AIRFLOW SWITCH SHALL GENERATE ALARM THRUGH BMS IF NO AIRFLOW IS PROVEN 45 SEC. (ADJ.) AFTER REQUEST.

BOILER ROOM VENTILATION SEQUENCE OF OPERATIONS

1. SUPPLY AND EXHAUST FANS SHALL BE CONTROLLED TO PROVIDE COOLING VENTILATION FOR THE BOILER ROOM. A FLOOR LEVEL, SPACE TEMPERATURE WILL BE PROVIDED AND USED TO CONTROL THE VENTILATION SYSTEM.

2. A BUILDING DIFFERENTIAL PRESSURE CONTROLLER WILL BE PROVIDED, AND WILL CONTROL SUPPLY AND EXHAUST FAN SPEEDS THROUGH THE FAN VFD ’S TO BALANCE SUPPLY AND EXHAUST AIRFLOWS. THE PURPOSE IS TO MAINTAIN A SLIGHT POSITIVE BUILDING PRESSURE WHEN IN OPERATION, ESPECIALLY WHEN THE EMERGENCY

GENERATOR IS IN OPERATION.

3. VENTILATION SYSTEM TEMPERATURE CONTROL SHALL BE AS FOLLOWS:

A. WHEN SPACE TEMPERATURE SENSOR REACHES SETPOINT (80 DEG. F – ADJ). – BOTH SUPPLY FAN

DAMPERS, AND EXHAUST FAN DAMPERS SHALL OPEN FOR NATURAL CONVECTION.

B. IF SPACE TEMPERATURE RISES TO 85 DEG. F, ONE SUPPLY FAN, AND ONE EXHAUST FAN SHALL START

WITH THE FAN VARIABLE SPEED DRIVE ON LOW SPEED. FAN SPEED SHALL RAMP UP AS SPACE

TEMPERTURE RISES OVER 85 DEG.F.

C. AT A SPACE TEMPERATURE READING OF 90 DEG. F, BOTH SUPPLY FANS, AND BOTH EXHAUST FANS SHALL RUN ON LOW SPEED. FAN SPEED SHALL INCREASE UNTIL FANS ARE AT FULL SPEED WHEN

SPACE TEMPERATURE IS 95 DEG.F (ADJ).

D. SUPPLY AND EXHAUST FAN SPEEDS SHALL BE CONTROLLED SEPERATELY TO MAINTAIN A FLOW

DIFFERENTIAL FOR MAINTAINING A POSITIVE BUILDING PRESSURE DIFFERENTIAL.

E. THE LEAD SUPPLY, EXHAUST FAN PAIR SHALL ALTERNATE WITH EACH CYCLE OF OPERATION.

F. FAN FAILURE SHALL ALARM BMS.

4. VENTILATION SYSTEM PRESSUE CONTROL SHALL BE AS FOLLOWS.

A. WHEN THE BOILER ROOM SUPPLY AN EXHAUST FANS ARE RUNNING – THE FANS SPEEDS SHALL BE BALANCED SO AS TO PROVIDE THE POSITIVE BUILDING PRESSURE DIFFERENTIAL OF 0.10" S.P. (ADJ).

CIRCULATING FAN SEQUENCE OF OPERATION:

FAN CONTROL: FAN SHALL RUN CONTINOUSLY TO CIRCULATE BOILER ROOM AIR. FAN SHALL STOP BY MANUAL OVERRIDE.

ALARMS: IF BMS IS COMMANDED CEILING FAN BUT NO STATUS HAS BEEN RECEIVE BY FAN CURRENT SENSOR (CS-1) AFTER 3

MIN.(ADJ.) REPORT ALARM TO BMS SYSTEM.

GENERAL NOTES

FIN TUBE RADIATOR SEQUENCE OF OPERATION:

OCCUPANCY: FIN TUBE RADIATOR SHALL BE ENABLED BY BMS OCCUPIED SCHEDULE. DURING UNOCCUPIED PERIOD

UNIT SHALL REMAIN DISABLE.

SYSTEM CONTROL: DURING OCCUPIED HEATING MODE UNIT SHALL MODULATE HOT WATER VALVE (V-1) TO MAINTAIN

SPACE TEMPERATURE (T-1) OF 70°F (ADJ.)

ALARMS: FIN TUBE RADIATOR SHALL BE SET IN ALARM IF SPACE TEMPERATURES REACH AND STAY IN HIGH AND LOW

TEMPERATURE LIMITS FOR 10 MIN. (ADJ.)

NTS2 FIN TUBE RADIATOR SCHEMATIC

KEYED NOTES

1 BACK - UP HEAT EXCHANGER FOR 2-200-HEX-001 ONLY. HEAT EXCHANGER

2-202-HEX-001 DOES NOT CONTAIN BACK - UP.

STEAM TO HOT WATER SYSTEM CONTROL DIAGRAM3

STEAM TO HOT WATER HEAT EXCHANGER SEQUENCE OF OPERATION:

(TYPICAL FOR 2-200-HEX-001, 2-200-HEX-002 & 2-202-HEX-001)

START: BMS SHALL ENABLE STEAM TO HEATING HOT WATER SYSTEM WHEN HEATING IS REQUIRED. BMS

SHALL ROTATE LEAD/LAG PUMPS DESIGNATION EVERY 7 DAYS.

START: UPON START UP THE STEAM CONTROL VALVE (V-1) SHALL MODULATE OPEN AND MAINTAIN HEATING HOT WATER LOOP SET POINT AND HOT WATER ISOLATION VALVE (M-1) SHALL OPEN. AFTER HOT WATER ISOLATION VALVE (M-1) HAVE BEEN CONFIRMED OPEN LEAD CIRCULATING PUMP VFD SHALL START BY ENABLING RELAY (R-1) AND SHALL MODULATE SPEED TO MAITAIN HEATING HOT WATER LOOP DIFFERENTIAL PRESSURE (DP-1) AT SET POINT WHILE MEETING BUILDING HEATING DEMAND. IF LEAD PUMP STATUS IS NOT DETECTED 30 SEC. (ADJ.) AFTER VFD HAS BEEN ENABLED, THE LAG PUMP SHALL START AND AN ALARM SHALL BE REPORTED TRHOUGH THE BMS. IF FAILURE IS REPORTED WITH LEAD HEAT

EXCHANGER, REDUNDANT BACKUP HEAT EXCHANGER SHALL TAKE OVER OPERATION.

OPERATION: HEAING HOT WATER SUPPLY WATER TEMPERATURE (T-1) TO THE BUILDING HEATING LOOP SHALL BE RESET BASED ON OUTSIDE AIR TEMPERATERUE (T-2) BY MODULATING STEAM VALVE (V-1).

MODULATE STEAM VALVE TO SUPPLY WATER AT A MAX TEMPERATURE OF 180°F (ADJ.) WHEN OUTSIDE AIR TEMPERATURE IS 30.0 °F (ADJ.) OR BELOW. AND MODULATE STEAM VALVE TO SUPPLY MAX TEMPERATURE OF 140°F (ADJ) WHEN OUTSIDE AIR TEMPERATURE IS 70°F(ADJ) OR HIGHER. FOR OUTSIDE AIR TEMPERATURE READINGS BETWEEN 30-70°F MODULATE HOT WATER LOOP TEMPERATURE SETPOINT BY SCALING SET POINT LINEARLY BETWEEN 140-180°F FOR RESPECTIVE OUTDOOR AIR TEMPEARATURE. THE MAXIMUM PRESSURE LIMIT IS THE PRESSURE REQUIRED TO PROVIDE FULL FLOW TO ALL HEATING CONTROL VALVES SIMULTANEOUSLY (PER TAB). THE MINIMUM PRESSURE LIMIT IS THE PRESSURE CORRELATING TO THE LOWEST SPEED THE PUMP MOTOR IS ALLOWED TO BE OPERATED AT (PER TAB).

ALARMS: ALL PUMPS SHALL BE MONITORED, AND PUMP OR VFD FAILURE SHALL BE REPORTED THROUGH THE BMS. HEATING HOT WATER TEMPERATURE SHALL BE MONITORED, HIGH AND LOW LIMITS ALRMS SHALL BE REPORTED THROUGH THE BMS. LOW AND HIGH HEATING HOT WATER DIFFERENTIAL PRESSURE

ALARM SHALL BE REPORTED TO THE BMS.

TYPICAL FOR 2-200-HEX-001, 2-200-HEX-002 AND 2-202-HEX-001

GENERATOR ROOM VENTILATION CONTROL DIAGRAM5

GENERATOR ROOM VENTILATION CONTROL SEQUENCE OF OPERATION:

CONTROL: IN THE EVENT OF A GENERATOR VENTILATION REQUEST (R-1). SYSTEM SHALL OPEN OUTSIDE AIR DAMPER (D-1) AND EXHAUST AIR DAMPER (D-2) AND CONFIRM DAMPERS OPEN POSITION. IF OPEN POSITION IS NOT CONFIRMED AFTER 1 MIN. (ADJ) GENERATE ALARM. AFTER DAMPER POSITION HAS BEEN CONFIRM SYSTEM SHALL REQUEST EXHAUST FAN (R-2) AND MAINTAIN GENERATOR ROOM TEMPERATURE (T-1) SETPOINT OF 75°F (ADJ.) BY MODULATING FAN (SC-1). ONCE GENERATOR VENTILATION REQUEST (R-1) HAS STOP, ALL DAMPERS SHALL RETURN TO THE ORIGINAL POSITION ONCE TEMPERATURE SETPOINT HAS BEEN REACHED. DURING COLD WAETHER SEASON MODULATE EXHAUST FAN (SC-1) AND OUTSIDE AIR DAMPER (D-1) TO MAINTAIN ROOM TEMPERATURE SETPOINT, GENERATOR ROOM UNIT HEATER (2-120B-UH-004) SHALL BE DISABLED UPON

GENERATOR VENTILATION REQUEST (R-1).

ALARMS: SHALL GENERATE ALARM IF OUTSIDE AIR AND EXHAUST AIR DAMPERS REMAIN CLOSE FOR MORE THAN 1 MIN. (ADJ.) AFTER VENTILATION REQUEST (R-1). SHALL GENERATE ALARM IF GENERATOR ROOM

TEMPERATURE (T-1) EXCEEDS 100°F (ADJ.).
