VAV SHUT-OFF TERMINAL UNITS

GENERAL: AN OVERRIDE SWITCH INTEGRAL TO EACH ZONE TEMPERATURE SENSOR SHALL RETURN THE RESPECTIVE AHU FROM UNOCCUPIED TO OCCUPIED BUT ONLY THE ZONE OVERRIDDEN SHALL RETURN TO OCCUPIED MODE. WHEN ANY OVERRIDE SWITCH IS ENERGIZED, AHU AND ALL VAV BOXES ASSOCIATED WITH THE ZONE OVERRIDDEN SHALL BE ENERGIZED THROUGH DDC CONTROL BUT ONLY THE ZONE OVERRIDDEN SHALL RETURN TO OCCUPIED MODE TEMPERATURE SETPOINTS. AFTER TWO HOURS, THE ZONE SHALL RETURN TO UNOCCUPIED MODE. ENERGIZED AHU AND ALL ASSOCIATED VAV BOXES SHALL BE DE-ENERGIZED UNLESS AHU IS UNDER CONTROL OF ANOTHER ZONE IN OVERRIDE POSITION. REFER TO GLOBAL

TEMPERATURE SETPOINT NOTE THIS SHEET.

COOLING-OCCUPIED: THE ZONE TEMPERATURE SENSOR THROUGH DDC CONTROL SHALL MODULATE THE PRIMARY AIR VALVE IN THE VAV BOX TO MAINTAIN GLOBAL ZONE TEMPERATURE SETPOINT, OPENING THE AIR VALVE ON A RISE IN SPACE TEMPERATURE, OR CLOSING IT ON A FALL IN SPACE

TEMPERATURE, (NOT TO FALL BELOW MINIMUM SCHEDULED PRIMARY AIR QUANTITY).

HEATING-OCCUPIED: THE PRIMARY AIR VALVE SHALL START IN ITS MINIMUM SCHEDULED POSITION THRU DDC CONTROL. THE ZONE TEMPERATURE SENSOR THROUGH DDC CONTROL SHALL MODULATE THE HOT WATER CONTROL VALVE TO MAINTAIN GLOBAL ZONE TEMPERATURE SETPOINT. ON A RISE IN ZONE TEMPERATURE, THE OPPOSITE SHALL OCCUR. IF SPACE TEMPERATURE IS SLOW TO RESPOND, CONTROLLER SHALL MODULATE PRIMARY AIR VALVE OPEN TO A MAX OF 80%. ON A RISE IN ZONE TEMPERATURE, THE OPPOSITE SHALL OCCUR.

COOLING-UNOCCUPIED: THE VAV BOX PRIMARY AIR VALVE SHALL BE FULLY CLOSED UNLESS THE ASSOCIATED AHU SUPPLY FAN IS ENERGIZED. ON A RISE IN ZONE TEMPERATURE ABOVE SETBACK SETPOINT (85°F, ADJ.) THE VAV BOX PRIMARY AIR VALVE SHALL MODULATE TO MAINTAIN SETPOINT. DDC CONTROLLER SHALL MAINTAIN 55°F SUPPLY AIR TEMPERATURE. AHU SHALL REMAIN ENERGIZED UNTIL ZONE SETBACK TEMPERATURE SETPOINT IS ACHIEVED. IF ZONE TEMPERATURE FALLS BELOW SETBACK SETPOINT, VAV BOX SHALL CLOSE AIR VALVE TO MIN. POSITION.

HEATING-UNOCCUPIED: THE VAV BOX PRIMARY AIR VALVE SHALL BE FULLY CLOSED UNLESS THE ASSOCIATED AHU SUPPLY FAN IS ENERGIZED. ON A FALL IN ZONE TEMPERATURE BELOW SETBACK SETPOINT (60°F, ADJ.) THE PRIMARY AIR VALVE SHALL OPEN TO 80%. DDC CONTROLLER SHALL MODULATE VAV BOX HOT WATER CONTROL VALVE TO MAINTAIN ZONE SETBACK TEMPERATURE SETPOINT. IF ZONE TEMPERATURE RISES ABOVE SETBACK

SETPOINT, THE OPPOSITE SHALL OCCUR.

SHALL MODULATE THE CHILLED WATER VALVE TO MAINTAIN 53°F (ADJ.) LEAVING AIR TEMPERATURE.

HOT WATER CONTROL VALVE SHALL BE FULLY CLOSED TO COIL. A SUPPLY AIR TEMPERATURE RESET

STRATEGY SHALL BE EMPLOYED. SUPPLY AIR TEMPERATURE SHALL BE RAISED IN ONE DEGREE

INCREMENTS UNTIL ONE ZONE DAMPER IS 90% OPEN. IF OA DRY BULB TEMPERATURE IS 65°F (ADJ.)

OR LOWER, THE SUPPLY AIR TEMPERATURE RESET SHALL BE NO HIGHER THAN 58°F (ADJ.). IF ANY

ZONE DAMPER IS 100% OPEN AND ZONE TEMPERATURE RISES ABOVE SETPOINT, SUPPLY AIR

TEMPERATURE SHALL BEGIN TO RESET LOWER.

COOLING-UNOCCUPIED: UNIT SHALL BE DE-ENERGIZED UNLESS THE AVERAGE OF THE ZONE

TEMPERATURES RISES ABOVE THE SETBACK TEMPERATURE SETPOINT. THE OA DAMPER SHALL BE

CLOSED.

HEATING-OCCUPIED: AHU SUPPLY FAN SHALL BE ENERGIZED AND RUN CONTINUOUSLY. O.A. FLOW

SHALL BE MAINTAINED AS DESCRIBED IN COOLING-OCCUPIED MODE ABOVE. WHEN MIXED AIR

TEMPERATURE DROPS TO 52°F, DISCHARGE AIR TEMPERATURE CONTROLLER THRU DDC CONTROL

SHALL MODULATE THE HOT WATER VALVE TO MAINTAIN 55°F LEAVING AIR TEMPERATURE. THE

CHILLED WATER VALVE SHALL BE FULLY CLOSED TO THE COIL.

HEATING-UNOCCUPIED: IF THE AVERAGE OF THE ASSOCIATED ZONE TEMPERATURES FALLS BELOW

THE HEATING NIGHT SETBACK TEMPERATURE THE AHU SHALL BE ENERGIZED. THE OA DAMPER

SHALL BE FULLY CLOSED. THE SUPPLY FAN SHALL MODULATE TO MAINTAIN DUCT STATIC PRESSURE WHILE THE VAV BOXES ARE INITIALLY AT MAXIMUM AIRFLOW. THE HOT WATER CONTROL VALVE SHALL REMAIN CLOSED UNLESS DISCHARGE AIR TEMPERATURE FALLS BELOW 55°F. ZONE HEATING SHALL BE MAINTAINED AT VAV BOXES. AS VAV BOX ZONES REACH SETPOINT, AIR VALVES SHALL

MODULATE TO MAINTAIN SETPOINT.

TRANSITION FROM OCCUPIED TO UNOCCUPIED: AUTOMATICALLY THRU DDC CONTROL AND PRESET

TIME SCHEDULE. SYSTEM SHALL ALSO BE ABLE TO BE RETURNED TO OCCUPIED MODE FROM

UNOCCUPIED MODE BY THE OPERATOR WORKSTATION. TRANSITION FROM COOLING TO HEATING

SHALL OCCUR WHEN CHILLED WATER CONTROL VALVE IS CLOSED AND MIXED AIR TEMP. FALLS

BELOW 52°F.

PRESSURE PROTECTION: A HIGH PRESSURE TRANSMITTER LOCATED AT THE SUPPLY FAN

DISCHARGE SHALL DE-ENERGIZE THE SUPPLY AIR FAN IF ITS SETPOINT, 5" WG, IS REACHED.

FREEZE PROTECTION: IF HOT WATER COIL DISCHARGE AIR TEMPERATURE FALLS

BELOW 40°F DURING HEATING MODE, THE FREEZESTAT SHALL CLOSE THE OUTSIDE AIR

DAMPER, DE-ENERGIZE THE AHU SUPPLY FAN AND FULLY OPEN THE HOT WATER AND

CHILLED WATER VALVES TO COIL.

CONDENSATE HIGH LEVEL PROTECTION: IF CONDENSATE HIGH LEVEL SWITCH IS

ACTIVATED, UNIT SHALL BE DE-ACTIVATED AND AN ALARM INITIATED.

MORNING WARM-UP: AHU SHALL EMPLOY OPTIMUM START PRIOR TO OCCUPIED

STATUS. THE OA DAMPER SHALL BE FULLY CLOSED. THE SUPPLY FAN SHALL MODULATE

TO MAINTAIN DUCT STATIC PRESSURE WHILE VAV BOXES ARE INITIALLY AT MAXIMUM

AIRFLOW. HOT WATER COIL VALVE SHALL BE FULLY OPEN. AS VAV BOX ZONES REACH

SETPOINT, PRIMARY AIR VALVES SHALL MODULATE TO MINIMUM AIRFLOW.

MORNING COOL-DOWN: THE UNIT SHALL EMPLOY OPTIMUM START PRIOR TO OCCUPIED

STATUS, THE UNIT SHALL GO INTO MORNING COOL-DOWN. THE OA DAMPER SHALL

FULLY CLOSE, THE SUPPLY FAN SHALL MODULATE TO MAINTAIN DUCT STATIC

PRESSURE, THE CW VALVE SHALL MODULATE TO MAINTAIN A 53°F (ADJ.) LEAVING AIR

TEMPERATURE AND THE HOT WATER VALVE SHALL BE FULLY CLOSED TO THE COIL.

ASSOCIATED VAV BOX AIR VALVES SHALL INITIALLY BE FULLY OPEN AND THEN

MODULATE TO MAINTAIN SPACE OCCUPIED TEMPERATURE SETPOINT, VAV BOX HW

VALVES SHALL BE FULLY CLOSED TO THE COIL.

ALARMS: ALARM IF LEAVING AIR TEMPERATURE EXCEEDS 60°F IN COOLING MODE OR

DROPS BELOW 50°F IN HEATING MODE. ALARM IF AHU SUPPLY FAN FAILS TO START OR

FAILS DURING OPERATION. ALARM IF UNIT DISCHARGE STATIC PRESSURE EXCEEDS 5"

W.G. ALARM IF CONDENSATE REACHES HIGH LEVEL. ALARM UPON SMOKE DETECTOR

ACTIVATION.

DEMAND CONTROL VENTILATION: IF ANY SPACE CARBON DIOXIDE LEVEL FALLS BELOW

SETPOINT (1,000 PPM, ADJ.), THE OUTSIDE AIRFLOW RATE SHALL BE AT THE MINIMUM

SCHEDULED VALUE AS INDICATED IN THE EQUIPMENT SCHEDULE. AS LEVEL INCREASES

ABOVE SETPOINT, THE OUTSIDE AIR DAMPER SHALL PROPORTIONALLY MODULATE

OPEN TO GENERATE THE SCHEDULED MAX OUTSIDE AIRFLOW RATE OVER A 1 HOUR

(ADJ.) TIME PERIOD UNTIL THE LEVEL FALLS BELOW THE SETPOINT, AFTER WHICH THE

DAMPER POSITION SHALL RETURN TO MINIMUM.
