1. VAV SHUTOFF (COOLING-ONLY) CONTROL - IF THE SPACE TEMPERATURE IS BELOW SETPOINT, THE BOX DAMPER SHALL BE AT THE LISTED DEAD BAND MINIMUM CFM. IF SPACE TEMPERATURE RISES ABOVE THE COOLING SETPOINT, THE CONTROL SHALL MODULATE THE BOX DAMPER BETWEEN THE LISTED DEAD BAND MINIMUM CFM AND THE LISTED COOLING MAXIMUM CFM TO SATISFY THE SPACE COOLING SETPOINT. BOX

CONTROLS SHALL REVERSE ACTION DURING “WARM-UP” CYCLES.

A. VAV HOT WATER REHEAT AND HEATING CONTROL:

a. REHEAT MODE -- THE FOLLOWING SEQUENCE SHALL BE IMPLEMENTED:

• IF THE SPACE TEMPERATURE IS IN THE DEAD BAND BETWEEN HEATING AND COOLING SET

POINTS, THE BOX DAMPER SHALL BE POSITIONED TO THE LISTED DEAD BAND MINIMUM CFM. IF

SPACE TEMPERATURE RISES ABOVE THE COOLING SETPOINT, THE CONTROL SHALL MODULATE

THE BOX DAMPER BETWEEN THE LISTED DEAD BAND MINIMUM CFM AND THE LISTED COOLING

MAXIMUM CFM TO SATISFY THE SPACE COOLING SETPOINT. WHEN THE ROOM TEMPERATURE IS

BELOW SETPOINT, THE BOX DAMPER AND HOT WATER VALVE SHALL BE SEQUENCED TO MAINTAIN

THE SPACE HEATING SET POINT AS FOLLOWS:

• 1ST STAGE OF HEATING SHALL BE TO POSITION THE BOX DAMPER AT ITS LISTED DEAD BAND

MINIMUM CFM AND MODULATE THE HOT WATER VALVE TO MAINTAIN SPACE TEMPERATURE, WITH

A HIGH LIMIT DISCHARGE AIR TEMPERATURE OF 20 DEGREES ABOVE THE SPACE HEATING SET

POINT (EXCEPT DURING WARM-UP CYCLES).

• IF AFTER 10 MINUTES THE SPACE HEATING SET POINT CANNOT BE MAINTAINED FOR 5 MINUTES, 2ND STAGE OF HEATING SHALL BE TO MODULATE THE BOX DAMPER FORM THE LISTED DEAD

BAND MINIMUM CFM TO THE LISTED REHEAT MAXIMUM CFM WHILE MAINTAINING A DISCHARGE AIR

TEMPERATURE OF 20 DEGREES ABOVE THE SPACE HEATING SET POINT.

• REVERSE THE SEQUENCE WHEN SPACE HEATING SETPOINT IS REACHED. WHEN IN A “WARM UP”

CYCLE, THE BOX DAMPER SHALL GO TO THE LISTED HEATING MAXIMUM CFM AND THE HOT

WATER VALVE SHALL BE MODULATED TO MAINTAIN THE SPACE HEATING SET POINT (AND SUPPLY

AIR TEMPERATURE NOT LIMITED TO 20 DEGREES ABOVE ROOM SET POINT).

• IF HOT WATER IS NOT AVAILABLE THE BOXES SHALL ACT AS SHUTOFF (COOLING ONLY) BOXES.

2. CONSTANT VOLUME HOT WATER REHEAT CONTROL – THE BOX DAMPER SHALL BE CONTROLLED TO

MAINTAIN THE LISTED CONSTANT VOLUME CFM, AND THE REHEAT VALVE SHALL BE MODULATED TO MAINTAIN

THE SPACE TEMPERATURE SET POINT.

3. ENERGY MANAGEMENT - EACH VAV BOX SHALL HAVE ITS OWN TIME OF DAY SCHEDULE FOR “OCCUPIED” AND

“UNOCCUPIED” CONTROL.

STATUS. WHEN THE FREEZE STAT IS TRIPPED THE FOLLOWING SEQUENCE SHALL OCCUR:

B. THE OUTSIDE AIR DAMPERS SHALL CLOSE AND THE MIXED AIR

C. DAMPER SHALL BE OPEN.

D. STEAM PREHEAT COIL VALVE SHALL OPEN TO 100%(ADJ)

E. COOLING COIL VALVE SHALL OPEN TO 50%(ADJ

F. CLOSE HUMIDIFIER CONTROL VALVE

3. HIGH/LOW STATIC SAFETY SHUTDOWN

A. THE UNIT SHALL SHUT DOWN AND GENERATE AN ALARM UPON RECEIVING A HIGH STATIC

SHUTDOWN SIGNAL. HIGH STATIC ALARM SETPOINT SHALL BE 1" BELOW DUCTWORK

PRESSURE CLASS.

B. THE UNIT SHALL SHUT DOWN AND GENERATE AN ALARM UPON RECEIVING A LOW STATIC

SHUTDOWN SIGNAL. LOW STATIC ALARM SETPOINT SHALL BE NEGATIVE 2" S.P.

C. SUPPLY FAN SHALL BE OFF OUTSIDE OF SCHEDULED OPERATING HOURS AND THE

OUTSIDE AIR DAMPER SHALL CLOSE.

4. SMOKE DETECTION

A. THE UNIT SHALL SHUT DOWN AND GENERATE AN ALARM UPON A DETECTOR TRIP ON

SUPPLY AIR OR RETURN AIR SMOKE DETECTOR. DISCHARGE AND RETURN SMOKE

DAMPERS SHALL CLOSE IN THIS EVENT.

5. SUPPLY FAN(S)

A. THE SUPPLY FANS SHALL RUN ANYTIME THE UNIT IS COMMANDED TO RUN, UNLESS

SHUTDOWN ON SAFETIES.

6. IN THE EVENT OF A SINGLE FAN FAILURE, THE REMAINING FANS IN THE FAN ARRAY SHALL

RAMP UP TO MEET REQUIRED AIRFLOW.

A. ALARMS:

a. SUPPLY FAN FAILURE

b. HIGH STATIC

7. STATUS OF MOTORIZED BACKDRAFT DAMPER (MBD)

8. STATUS OF MBD TO BE VERIFIED AS OPEN, FAN SHALL NOT START IF MBD IS CLOSED.

9. SUPPLY AIR DUCT STATIC PRESSURE CONTROL

A. THE CONTROLLER SHALL MEASURE DUCT STATIC PRESSURE AND SHALL MODULATE THE

SUPPLY FAN VFD SPEED TO MAINTAIN THE DUCT STATIC PRESSURE SETPOINT. THE

SUPPLY FAN VFD SPEED SHALL NOT DROP BELOW 30%(ADJ.). THE INITIAL DUCT STATIC

PRESSURE SETPOINT SHALL BE 1.0", AND BE ADJUSTED UP DURING THE BALANCING

PROCESS. THE FINAL DUCT STATIC PRESSURE SETPOINT SHALL BE DETERMINED, SET,

AND DOCUMENTED BY THE BALANCING CONTRACTOR. THE SETPOINT SHALL BE

SUFFICIENT TO MEET THE VAV BOX AIRFLOW REQUIREMENTS DURING DESIGN

CONDITIONS.

E. STATUS OF MBD TO BE VERIFIED AS OPEN, FAN SHALL NOT START IF MBD IS CLOSED.

11. RETURN AIRFLOW

A. THE RETURN FAN VFD SHALL MODULATE IN UNISON WITH THE SUPPLY FAN VFD. RETURN

AIRFLOW SETPOINT SHALL BE EQUAL TO SUPPLY AIR FLOW MINUS 10%(ADJ.) AND MINUS

EXHAUST AIR FLOW. THE RETURN FAN VFD SPEED SHALL NOT DROP BELOW 20%(ADJ.)

B. ALARMS

a. HIGH RETURN AIRFLOW (10% ABOVE SUPPLY AIRFLOW)

b. LOW RETURN AIRFLOW (30% BELOW SUPPLY AIRFLOW)

12. PREHEAT COIL

A. THE CONTROLLER SHALL MEASURE THE PREHEAT SECTION AIR TEMPERATURE AND

MODULATE THE PREHEAT COIL VALVE TO MAINTAIN SETPOINT. THE PREHEAT SECTION

TEMPERATURE SETPOINT SHALL EQUAL THE SUPPLY AIR TEMPERATURE SETPOINT MINUS

THE FAN HEAT OFFSET VALUE.

B. PREHEAT COIL SHALL BE ENABLED WHENEVER:

C. OUTSIDE AIR TEMPERATURE IS LESS THAN 50 DEG(ADJ),

D. AND THE ECONOMIZER IS DISABLED…
