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.

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

WILMINGTON, DELAWARE
SEQUENCE OF OPERATIONS - AHU-2 (MER 245)
AHU-2 (MER 245) SEQUENCE OF OPERATION
1. GENERAL
UNIT AHU-2 AND RETURN FAN 1-RF 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, D-3, SD-1 AND SD-2 SHALL BE CLOSED. WHEN THE UNIT IS “ON” D-1, D-2, D-3, SD-1 AND SD-2 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, D-2 AND D-3; D-1 ASSUMES MINIMUM OUTSIDE AIR POSITION (D-3 IS CLOSED AND D-2 IS OPEN.)
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, 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 OPEN AND D-1 IS CLOSED TO MINIMUM OUTSIDE AIR IN THIS MODE V-2 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 BY USING HIGH PRESSURE SENSOR SPS-2 LOCATED AT THE SUPPLY AIR FAN DISCHARGE PREVENTS THE SUPPLY AIR FAN FROM DEVELOPING OVER 3” STATIC PRESSURE. IF STATIC PRESSURE AT SPS-2
EXCEEDS 3” THE SUPPLY FAN STOPS.
4. HUMIDITY CONTROL
WHEN THE DCP IS NOT CALLING FOR HUMIDIFICATIN (BASED ON HUMIDITY SENSED 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 HUMIDIFICATION THE, 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 V03 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 THE 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 AND RETURN FANS SHALL STOP AND THE ALARM SIGNAL SHALL BE TRANSMITTED TO THE FIRE ALARM SYSTEM, SMOKE
DAMPERS SD-1 AND SD-2 DHALL CLOSE. THE SUPPLY AND RETURN FANS SHALL RESTART AND SMOKE DAMPERS SHALL BE 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.

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-2 DAMPER D-2 IS CLOSED AND DAMPER D-1 IS OPENED TO
MAXIMUM OUTSIDE AIR POSITION. 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-2 THEN DAMPERS D-1 AND D-2 MODULATE TO MAINTAIN THE
SCHEDULED SUPPLY AIR TEMPERATURE AND THE PUMP RUNS. IF D-2 IS FULLY OPENED AND D-1 IS AT MINIMUM OUTSIDE AIR POSITION, V-2 MODULATES OPEN TO MAINTAIN THE SUPPLY AIR
TEMPERATURE.
3. AIR FLOW CONTROL
THE SUPPLY AND EXHAUST FANS SHALL RUN AT CONSTANT SPEED PROVIDING CONSTANT AIR FLOW.
4. HUMIDITY CONTROL
WHEN THE DCP IS NOT CALLING FOR HUMIDIFICATION SENSED BY SPACE 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.
EXHAUST 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
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 AND EXHAUST FANS STOP AND THE ALARM SIGNAL IS TRANSMITTED TO THE FIRE ALARM SYSTEM. DAMPERS
D-1 AND D-2 SHALL CLOSE. SUPPLY AND EXHAUST FANS SHALL RESTART AND THE DAMPERS SHALL OPEN WHEN THE FIRE ALARM CIRCUIT IS MANUALLY RESET.
