WILMINGTON, DELAWARE

SEQUENCE OF OPERATIONS - AHU FOR CANTEEN (2ND FLOOR ROOF)

AHU FOR CANTEEEN (2nd FLOOR ROOF) - SEQUENCE OF OPERATION

1. GENERAL

UNIT IS NORMALLY STARTED AND STOPPED BY THE DCP OR REMOTELY AT THE BMS. H-O-A SWITCH SHALL BE KEPT IN THE ‘AUTO’ POSITION. ‘HAND’ AND

‘OFF’ POSITIONS SHALL BE USED FOR MAINTENANCE ONLY. WHEN THE UNIT IS ‘OFF’ D-1 SHALL BE CLOSED. WHEN THE UNIT IS ‘ON’ D-1 SHALL BE FULLY

OPENED.

2. TEMPERATURE CONTROL

SPACE TEMPERATURE SENSED BY T-1 SHALL BE MAINTAINED AT SETPOINT VIA DCP BY MODULATING V-1 AND V-2 IN SEQUENCE.

3. AIR FLOW CONTROL

THE SUPPLY FAN SHALL RUN AT CONSTANT SPEED PROVIDING CONSTANT AIR FLOW.

4. HUMIDITY CONTROL

WHEN THE DCP IS NOT CALLING FOR HUMIDIFICATION SENSED BY RETURN AIR SENSOR H-2, TWO-WAY “ON-OFF” CONTROL VALVE V-3 SHALL REMAIN

CLOSED. WHEN THE DCP IS CALLING FOR HUMIDIFICATION, V-3 SHALL OPEN.

RETURN AIR HUMIDITY SHALL BE MAINTAINED AT SETPOINT SENSED BY H-2 VIA DCP BY MODULATING CONTROL VALVE V-4 TO MAINTAIN THE DESIRED

HUMIDITY. THE DCP SHALL OVERRIDE THE CONTROL TO MAINTAIN HUMIDITY IN SUPPLY DUCT BELOW 80% AS SENSED BY H-1. DCP SHALL CLOSE VALVE

V-3 WHENEVER THE SUPPLY FAN IS OFF. VALVE V-4 SHALL BE INTERLOCKED WITH A TEMPERATURE SWITCH TO KEEP THE HUMIDIFIER OFF UNTIL

CONDENSATE TEMPERATURE APPROACHES STEAM TEMPERATURE.

5. FREEZE PROTECTION

IF THE AIR TEMPERATURE SENSED BY T-3 FALLS BELOW 45°F AN ALARM SIGNAL SHALL INDICATE AT THE DCP AND BMS. IF THIS TEMPERATURE FALLS

BELOW 40°F THE SUPPLY FAN SHALL SHUT DOWN, THE DAMPER D-1 SHALL CLOSE AND A CRITICAL ALARM SHALL INDICATE AT THE DCP AND BMS.

6. EMERGENCY SHUTDOWN/RESTART

WHEN SMOKE IS DETECTED BY THE DUCT MOUNTED SMOKE DETECTOR THE SUPPLY FAN STOPS AND THE ALARM SIGNAL IS TRANSMITTED TO THE FIRE

ALARM SYSTEM, DAMPERS D-1 AND D-2 SHALL CLOSE. SUPPLY FAN SHALL RESTART AND THE DAMPERS OPEN WHEN THE FIRE ALARM CIRCUIT IS

MANUALLY RESET.

SEQUENCE OF OPERATIONS – AHU FOR NUCLEAR MEDICINE

AHU FOR NUCLEAR MED. - SEQUENCE OF OPERATION

1. GENERAL

UNIT IS NORMALLY STARTED AND STOPPED BY THE DCP OR REMOTELY AT THE BMS. H-O-A SWITCH SHALL BE KEPT IN THE “AUTO” POSITION. “HAND” AND

“OFF” POSITIONS SHALL BE USED FOR MAINTENANCE ONLY. WHEN THE UNIT IS “OFF” D-1 SHALL BE CLOSED. WHEN THE UNIT IS “ON” D-1 SHALL BE FULLY

OPENED.

2. TEMPERATURE CONTROL

SPACE TEMPERATURE SENSED BY T-1 SHALL BE MAINTAINED AT SETPOINT VIA DCP BY MODULATING V-1 AND V-2 IN SEQUENCE.

3. AIR FLOW CONTROL

THE SUPPLY FAN SHALL RUN AT CONSTANT SPEED PROVIDING CONSTANT AIR FLOW.

4. HUMIDITY CONTROL

WHEN THE DCP IS NOT CALLING FOR HUMIDIFICATION SENSED BY HUMIDISTAT H-1, TWO-WAY “ON-OFF” CONTROL VALVE V-3 SHALL REMAIN CLOSED.

WHEN THE DCP IS CALLING FOR HUMIDIFICATION, V-3 SHALL OPEN.

RETURN AIR HUMIDITY SHALL BE MAINTAINED AT SETPOINT SENSED BY H-1 VIA DCP BY MODULATING CONTROL VALVE V-4 TO MAINTAIN THE DESIRED

HUMIDITY. THE DCP SHALL OVERRIDE THE CONTROL TO MAINTAIN HUMIDITY IN SUPPLY DUCT BELOW 80% AS SENSED BY H-2. DCP SHALL CLOSE VALVE

V-3 WHENEVER THE SUPPLY FAN IS OFF. VALVE V-4 SHALL BE INTERLOCKED WITH A TEMPERATURE SWITCH TO KEEP THE HUMIDIFIER OFF UNTIL

CONDENSATE TEMPERATURE APPROACHES STEAM TEMPERATURE.

5. FREEZE PROTECTION

SEQUENCE OF OPERATIONS – AHU-3 (MER 2147)

AHU-3 (MER 2147) SEQUENCE OF OPERATION

1. GENERAL

UNIT AHU-3 AND RETURN FAN RF-6 ARE NORMALLY STARTED AND STOPPED BY THE DCP OR REMOTELY AT THE BMS. H-O-A SWITCH SHALL BE KEPT IN THE "AUTO" POSITION. "HAND" AND "OFF" POSITIONS

SHALL BE USED FOR MAINTENANCE ONLY. WHEN THE UNIT IS "OFF" D-1, D-2 AND D-3 SHALL BE CLOSED. WHEN THE UNIT IS "ON" D-1, D-2 AND D-3 SHALL BE OPEN

2. TEMPERATURE CONTROL

SUPPLY AIR TEMPERATURE SENSED BY T-1 SHALL BE MAINTAINED AT SETPOINT VIA DCP BY MODULATING EITHER V-1 AND V-2 OR D-1, D-2 AND D-3 IN SEQUENCE.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR PROVIDED BY BMS IS ABOVE 65°F DCP PREVENTS MODULATION OF D-1 AND D-2; D-1 ASSUMES MINIMUM OUTSIDE AIR POSITION AND D-2 IS OPENED. V-2

MODULATES TO MAINTAIN SUPPLY AIR TEMPERATURE SENSED BY T-1.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR PROVIDED BY BMS IS BETWEEN 65°F AND THE SUPPLY AIR TEMPERATURE SENSED BY T-1 DAMPER D-2 IS CLOSED, DAMPER D-1 IS OPEN TO MAXIMUM

OUTSIDE AIR POSITION AND D-3 IS FULLY OPENED. V-1 MODULATES TO MAINTAIN THE SUPPLY AIR TEMPERATURE SENSED BY T-1.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR PROVIDED BY BMS IS BELOW THE SUPPLY AIR TEMPERATURE SENSED BY T-1 THEN DAMPERS D-1, D-2 AND D-3 MODULATE TO MAINTAIN THE SCHEDULED

SUPPLY AIR TEMPERATURE. IF D-2 IS OPENED AND D-1 IS CLOSED TO MINIMUM OUTSIDE AIR. V-1 MODULATES TO MAINTAIN THE SUPPLY AIR TEMPERATURE.

3. AIR FLOW CONTROL

THE SUPPLY AIR FLOW IS CONTROLLED BY DCP MODULATING SUPPLY FAN VARIABLE SPEED MOTOR CONTROLLER (VSMC) TO MAINTAIN THE DUCT STATIC PRESSURE SETPOINT AS SENSED BY SPS-1.

THE DCP BY USING TOTAL SUPPLY AIR AND RETURN AIR FLOW SIGNALS SHALL RESET THE RETURN AIR FAN VSMC TO MAINTAIN A CONSTANT CFM DIFFERENCE BETWEEN THE SUPPLY AIR FAN CFM AND THE

RETURN AIR FAN CFM.

THE DCCP USING HIGH STATIC PRESSURE SENSOR SPS-2 LOCATED AT THE SUPPLY FAN DISCHARGE SHALL PREVENT THE SUPPLY FAN FROM DEVELOPING OVER 3” OF STATIC PRESSURE (FIELD

ADJUSTABLE). IF STATIC PRESSURE AT SPS-2 EXCEEDS 3” THE SUPPLY AND RETURN FANS SHALL STOP AND THE ALARM SIGNAL SHALL INDICATE ON DCP AND BMS.

4. HUMIDITY CONTROL

WHEN THE DCP IS NOT CALLING FOR HUMIDIFICATION SENSED BY RETURN AIR HUMIDISTAT H-1, THE TWO-WAY “ON-OFF” CONTROL VALVE V-3 SHALL REMAIN CLOSED. WHEN THE DCP IS CALLING THE

HUMIDIFICATION, V-3 SHALL OPEN.

RETURN AIR HUMIDITY SHALL BE MAINTAINED AT SETPOINT VIA DCP OR MODULATING CONTROL VALVE V-4 TO MAINTAIN THE DESIRED HUMIDITY. THE DCP SHALL OVERRIDE THE CONTROL TO MAINTAIN

HUMIDITY IN SUPPLY DUCT BELOW 80% AS SENSED BY H-2.

DCP SHALL CLOSE VALVE V-3 WHENEVER THE SUPPLY FAN IS OFF.

VALVE V-4 SHALL BE INTERLOCKED WITH A TEMPERATURE SWITCH TO KEEP THE HUMIDIFIER OFF UNTIL CONDENSATE TEMPERATURE APPROACHES STEAM TEMPERATURE.

5. FREEZE PROTECTION

IF THE AIR TEMPERATURE SENSED BY T-3 FALLS BELOW 45°F AN ALARM SIGNAL SHALL INDICATE AT THE DCP AND BMS. IF THIS TEMPERATURE FALLS BELOW 40°F THE SUPPLY AND RETURN FANS SHALL

SHUT DOWN, DAMPER D-1 SHALL CLOSE AND A CRITICAL ALARM SHALL INDICATE AT THE DCP AND BMS.

6. EMERGENCY SHUTDOWN/RESTART

WHEN SMOKE IS DETECTED BY THE DUCT MOUNTED SMOKE DETECTOR THE SUPPLY AND RETURN FANS SHALL STOP AND THE ALARM SIGNAL SHALL BE TRANSMITTED TO THE FIRE ALARM SYSTEM.

DAMPERS D-1, D-2 AND D-3 SHALL CLOSE. SUPPLY AND RETURN FANS SHALL RESTART AND THE DAMPERS SHALL OPEN WHEN THE FIRE ALARM CIRCUIT IS MANUALLY RESET.

7. EMERGENCY CONSTANT SPEED OPERATION

UPON FAILURE OF THE VSMC THE SUPPLY AND RETURN FANS SHALL BE STARTED/STOPPED MANUALLY AT THE DCP OR THE BMS THROUGH THE BYPASS STARTER. FANS SHALL THEN OPERATE AT

CONSTANT SPEED.

SEQUENCE OF OPERATIONS – AHU-4 (MER 2147)

(ASSOCIATED WITH AHU-1 MER 245)

AHU-1 (MER 245) AND AHU-4 (MER 2147) - SEQUENCE OF OPERATION

1. GENERAL

UNITS ARE NORMALLY STARTED AND STOPPED BY THE DCP OR REMOTELY AT THE BMS. H-O-A SWITCH SHALL BE KEPT IN THE “AUTO” POSITION. “HAND” AND “OFF”

POSITIONS SHALL BE USED FOR MAINTENANCE ONLY. WHEN THE UNITS ARE “OFF” D-1 SHALL BE CLOSED. WHEN THE UNITS ARE “ON” D-1 SHALL BE FULLY OPEN.

2. TEMPERATURE CONTROL

SUPPLY AIR TEMPERATURE SENSED BY T-1 SHALL BE MAINTAINED AT SETPOINT VIA DCP BY MODULATING V-1 AND V-2 IN SEQUENCE.

PUMP 1-P7 RUNS WHEN OUTDOOR AIR TEMPERATURE AT T-1 IS BELOW 45°F AND ABOVE 80°F. PUMP IS OFF WHEN OUTDOOR AIR TEMPERATURE IS BETWEEN 46°F AND

79°F.

3. AIR FLOW CONTROL

THE SUPPLY FAN SHALL RUN AT CONSTANT SPEED PROVIDING CONSTANT AIR FLOW.

4. HUMIDITY CONTROL

WHEN THE DCP IS NOT CALLING FOR HUMIDIFICATION (BASED ON HUMIDITY SENSED BY THE EXHAUST BY THE EXHAUST AIR HUMIDISTAT H-1), THE TWO-WAY “ON-OFF”

CONTROL VALVE V-3 SHALL REMAIN CLOSED. WHEN THE DCP IS CALLING FOR HUMIDIFICATIN, V-3 SHALL OPEN.

EXHAUST AIR HUMIDITY SHALL BE MAINTAINED AT SETPOINT VIA DCP BY MODULATING CONTROL VALVE V-4 TO MAINTAIN THE DESIRED HUMIDITY. THE DCP SHALL

OVERRIDE THE CONTROL TO MAINTAIN HUMIDITY IN SUPPLY DUCT BELOW 80% AS SENSED BY H-2.

DCP SHALL CLOSE VALVE V-3 WHENEVER THE SUPPLY FAN IS OFF.

VALVE V-4 SHALL BE INTERLOCKED WITH A TEMPERATURE SWITCH TO KEEP THE HUMIDIFIER OFF UNTIL CONDENSATE TEMPERATURE APPROACHES STEAM

TEMPERATURE.

5. FREEZE PROTECTION

IF THE AIR TEMPERATURE SENSED BY T-2 FALLS BELOW 45°F AN ALARM SIGNAL SHALL INDICATE AT THE DCP AND BMS. IF THIS TEMPERATURE FALLS BELOW 40°F THE

SUPPLY FAN SHALL SHUT DOWN, D-1 SHALL CLOSE AND A CRITICAL ALARM SHALL INDICATE AT THE DCP AND BMS.

6. EMERGENCY SHUTDOWN/RESTART

WHEN SMOKE IS DETECTED BY THE DUCT MOUNTED SMOKE DETECTOR THE SUPPLY FAN SHALL SHUT OFF AND AN ALARM SIGNAL SHALL BE TRANSMITTED TO THE FIRE

ALARM SYSTEM, DAMPER D-1 SHALL CLOSE, EXHAUST FAN SERVICING AREAS OF THE SUPPLY FAN SHALL CONTINUE TO RUN.

SUPPLY FAN RESTARTS AND DAMPER D-1 OPENS WHEN THE FIRE ALARM CIRCUIT IS MANUALLY RESET.

SEQUENCE OF OPERATIONS – AHU-6 (2ND FLOOR ROOF)

AHU-6 (2ND FLOOR ROOF ) SEQUENCE OF OPERATION

1. GENERAL

SUPPLY AND RETURN FANS ARE NORMALLY STARTED AND STOPPEED BY THE DECP OR REMOTELY AT THE BMS. H-O-A SWITCH SHALL BE KEPT IN THE “AUTO” POSITION. “HAND” AND “OFF” POSITIONS SHALL

BE USED FOR MAINTENANCE ONLY. WHEN THE UNIT IS “OFF” D-1, D-2 AND D-3 SHALL BE CLOSED. WHEN THE UNIT IS “ON” D-1, D-2 AND D-3 SHALL BE OPENED.

2. TEMPERATURE CONTROL

SUPPLY AIR TEMPERATURE SENSED BY T-1 SHALL BE MAINTAINED AT SETPOINT VIA DCP BY MODULATING EITHER V-1 AND V-2 OR D-1, D-2 AND D-3 IN SEQUENCE.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR PROVIDED BY BMS IS ABOVE 65°F DCP PREVENTS MODULATION OF D-1 AND D-2; D-1 ASSUMES MINIMUM OUTSIDE AIR POSITION AND D-2 IS OPENED. V-2

MODULATES TO MAINTAIN SUPPLY AIR TEMPERATURE SENSED BY T-1.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR PROVIDED BY BMS IS BETWEEN 65°F AND THE SUPPLY AIR TEMPERATURE SENSED BY T-1 DAMPER D-2 IS CLOSED AND DAMPERS D-1 AND D-3 ARE OPEN

(MAXIMUM OUTSIDE AIR POSITION). V-2 MODULATES TO MAINTAIN THE SUPPLY AIR TEMPERATURE SENSED BY T-1.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR PROVIDED BY BMS IS BETWEEN 65°F AND THE SUPPLY AIR TEMPERATURE SENSED BY T-1 DAMPER D-2 IS CLOSED AND DAMPERS D-1 AND D-3 ARE OPEN

(MAXIMUM OUTSIDE AIR POSITION). V-2 MODULATES TO MAINTAIN THE SUPPLY AIR TEMPERATURE SENSED BY T-1.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR PROVIDED BY BMS IS BELOW THE SUPPLY AIR TEMPERATURE SENSED BY T-1 THEN DAMPERS D-1, D-2 AND D-3 MODULATE TO MAINTAIN THE SCHEDULED

SUPPLY AIR TEMPERATURE. IF D-2 IS OPENED AND D-1 IS CLOSED TO MINIMUM OUTSIDE AIR. V-1 MODULATES TO MAINTAIN THE SUPPLY AIR TEMPERATURE.

3. AIR FLOW CONTROL

THE SUPPLY AIR FLOW IS CONTROLLED BY DCP MODULATING SUPPLY FAN VARIABLE SPEED MOTOR CONTROLLER (VSMC) TO MAINTAIN THE DUCT STATIC PRESSURE SETPOINT AS SENSED BY SPS-1.

THE DCP BY USING TOTAL SUPPLY AIR AND RETURN AIR FLOW SIGNALS SHALL RESET THE RETURN AIR FAN VSMC TO MAINTAIN A CONSTANT CFM DIFFERENCE BETWEEN THE SUPPLY AIR FAN CFM AND THE

RETURN AIR FAN CFM.

THE DCCP USING HIGH STATIC PRESSURE SENSOR SPS-2 LOCATED AT THE SUPPLY FAN DISCHARGE SHALL PREVENT THE SUPPLY FAN FROM DEVELOPING OVER 3” OF STATIC PRESSURE (FIELD

ADJUSTABLE). IF STATIC PRESSURE AT SPS-2 EXCEEDS 3” THE SUPPLY AND RETURN FANS SHALL STOP AND THE ALARM SIGNAL SHALL INDICATE ON DCP AND BMS.

4. HUMIDITY CONTROL

WHEN THE DCP IS NOT CALLING FOR HUMIDIFICATION SENSED BY RETURN AIR HUMIDISTAT H-1, THE TWO-WAY “ON-OFF” CONTROL VALVE V-3 SHALL REMAIN CLOSED. WHEN THE DCP IS CALLING THE

HUMIDIFICATION, V-3 SHALL OPEN.

RETURN AIR HUMIDITY SHALL BE MAINTAINED AT SETPOINT VIA DCP OR MODULATING CONTROL VALVE V-4 TO MAINTAIN THE DESIRED HUMIDITY. THE DCP SHALL OVERRIDE THE CONTROL TO MAINTAIN

HUMIDITY IN SUPPLY DUCT BELOW 80% AS SENSED BY H-2.

DCP SHALL CLOSE VALVE V-3 WHENEVER THE SUPPLY FAN IS OFF.

VALVE V-4 SHALL BE INTERLOCKED WITH A TEMPERATURE SWITCH TO KEEP THE HUMIDIFIER OFF UNTIL CONDENSATE TEMPERATURE APPROACHES STEAM TEMPERATURE.

5. FREEZE PROTECTION

IF THE AIR TEMPERATURE SENSED BY T-3 FALLS BELOW 45°F AN ALARM SIGNAL SHALL INDICATE AT THE DCP AND BMS. IF THIS TEMPERATURE FALLS BELOW 40°F THE SUPPLY AND RETURN FANS SHALL

SHUT DOWN, DAMPER D-1 SHALL CLOSE AND A CRITICAL ALARM SHALL INDICATE AT THE DCP AND BMS.

6. EMERGENCY SHUTDOWN/RESTART

WHEN SMOKE IS DETECTED BY THE DUCT MOUNTED SMOKE DETECTOR THE SUPPLY AND RETURN FANS SHALL STOP AND THE ALARM SIGNAL SHALL BE TRANSMITTED TO THE FIRE ALARM SYSTEM.

DAMPERS D-1, D-2 AND D-3 SHALL CLOSE. SUPPLY AND RETURN FANS SHALL RESTART AND THE DAMPERS SHALL OPEN WHEN THE FIRE ALARM CIRCUIT IS MANUALLY RESET.

7. EMERGENCY CONSTANT SPEED OPERATION

UPON FAILURE OF THE VSMC THE SUPPLY AND RETURN FANS SHALL BE STARTED/STOPPED MANUALLY AT THE DCP OR THE BMS THROUGH THE BYPASS STARTER. FANS SHALL THEN OPERATE AT

CONSTANT SPEED.

SEQUENCE OF OPERATIONS

VAV SYSTEM CONTROL:

COOLING MODE:

On a rise in space temperature above the space temperature cooling set point, the damper will modulate from the minimum CFM set point to the maximum CFM set point. As the space temperature drops, the damper will modulate to the minimum CFM set point.

HEATING MODE:

On a drop in space temperature below the heating space temperature set point, the damper will modulate to the minimum heating CFM set point. On a further drop in space temperature below the space temperature set point, the heating coil valve will modulate to maintain the heating space temperature to it’s set point. As the temperature rises the reverse will occur.
