Project Title

SEQUENCE OF OPERATIONS - AHU-1 (MER 7003)

AHU-1 (MER #7003)

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

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

3. AIF FLOW CONTROL

THE SUPPLY AIRFLOW SHALL BE CONTROLLED BY THE DCP MODULATING THE SUPPLY FAN VARIABLE SPEED MOTOR CONTROLLER (VSMC) TO

MAINTAIN 1.5” OF DUCT STATIC PRESSURE (FIELD ADJUSTABLE) SENSED BY SPS-1.

THE DCP 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 FAN SHALL STOP.

4. HUMIDITY CONTROL

WHEN THE DCP IS NOT CALLING FOR HUMIDIFICATION SENSED BY SPACE AIR 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; (FIELD VERIFY INTERLOCK) 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, 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 AND RETURN FANS SHALL RESTART AND THE DAMPERS SHALL OPEN WHEN THE

FIRE ALARM CIRCUIT IS MANUALLY RESET.

SEQUENCE OF OPERATIONS – TYPICAL FOR AHU-2 & AHU-3 (MER 7060A & 7074)

AHU-2 (MER #7060A), AHU-3 (MER #7074)

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 AIR TEMPERATURE SENSED BY THE ROOM TEMPERATURE SENSOR 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 HUMIDITIY 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; (FIELD VERIFY INTERLOCK) 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, 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 AND RETURN FANS SHALL RESTART AND THE DAMPERS OPEN WHEN THE FIRE

ALARM CIRCUIT IS MANUALLY RESET.

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.

1. GENERAL

SUPPLY AND RETURN FANS 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 OPENED.

2. TEMPERATURE CONTROL

SUPPLY AIR TEMPERATURE SENSED BY T-1 SHALL BE MAINTAINED AT SETPOINT VIA DCP BY MODULATING EITHER V-1 AND V02 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-1 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 DAMPER D-1 IS OPENED TO MAXIMUM OUTSIDE AIR POSITION. V-1 MODULATES OPEN TO MAINTAIN THE SUPPLY AIR TEMPERATURE.

3. AIR FLOW CONTROL

THE SUPPLY AIR FLOW IS CONTROLLED BY THE 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 DCP 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, 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 VIA DCP BY MODULATING CONTROL VALVE V-4 TO MAINTAIN THE DESIRED HUMMIDITY. 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 SUPPY FAN IS OFF.

VALVE V-4 SHALL BE INTERLOCKED WITH A TEMPERATURE SWITCH (FIELD VERIFY INTERLOCK) 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 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.
