SEQUENCE OF OPERATION - VARIABLE AIR VOLUME (VAV) UNIT

EQUIPMENT

THE AIRSIDE SYSTEMS, AS IT APPLIES TO THE BUILDING AUTOMATION SYSTEM

(BAS), CONSISTS OF THE FOLLOWING EQUIPMENT:

VARIABLE AIR VOLUME (VAV) UNITS,

GENERAL

AIR TERMINAL UNITS SHALL BE PRESSURE INDEPENDENT UNITS, WITH HOT

WATER REHEAT COILS (WHERE APPLICABLE). EACH UNIT SHALL BE SUPPLIED

WITH CUSTOM PROGRAMMABLE APPLICATION CONTROLLERS. THE BAS SHALL

PERFORM THE FOLLOWING TERMINAL UNIT CONTROL STRATEGIES AND PROVIDE

THE POINTS AS REQUIRED FOR THE SPECIFIED MONITORING AND DIAGNOSTICS:

SETPOINT CONTROL: THE BAS SHALL EDIT THE OPERATING MODE, AIRFLOW

SETPOINTS, DAMPER POSITIONS, AND ZONE TEMPERATURE SETPOINT OF EACH

BOX. ALL SETPOINTS SHALL BE OPERATOR ADJUSTABLE. INDIVIDUAL ZONE

SETPOINT AND CONTROL LOGIC SHALL RESIDE AT THE ZONE LEVEL, AND NOT BE

DEPENDENT UPON THE BAS FOR CONTROL. UPON LOSS OF COMMUNICATION, THE

TERMINAL UNIT WILL CONTINUE TO CONTROL TO CURRENT SETPOINTS.

RUN CONDITIONS

TERMINAL UNIT/ AHU INTERFACE:

AT MINIMUM, ALL TERMINAL UNITS (TU) SERVED BY AN AIR HANDLING UNIT (AHU)

SHALL BE LINKED WITH THE RESPECTIVE AHU CONTROLLER TO PERFORM THE

FOLLOWING FUNCTIONS:

ZONE OCCUPANCY SCHEDULE: THE SCHEDULE SHALL AUTOMATICALLY SELECT

THE OCCUPIED OR UNOCCUPIED OPERATING MODE OF THE AHU. ACTIVATION OF

TIMED OVERRIDE SWITCH ON ZONE TEMPERATURE SENSORS (WHERE

APPLICABLE)SHALL ONLY RESET ZONE HEATING AND COOLING SETPOINTS TO

"OCCUPIED" VALUES, BUT SHALL NOT OTHERWISE AFFECT SCHEDULED

UNOCCUPIED OPERATING MODE OF AHU.

DUCT STATIC PRESSURE ALGORITHM: SEE AHU CONTROL SEQUENCE.

ZONE OPTIMAL START:

THE UNITS SHALL USE AN OPTIMAL START ALGORITHM FOR MORNING START-UP.

THIS ALGORITHM SHALL MINIMIZE THE UNOCCUPIED WARM-UP OR COOL-DOWN

PERIOD WHILE STILL ACHIEVING COMFORT CONDITIONS BY THE START OF THE

SCHEDULED OCCUPIED PERIOD. THE LEARNING ADAPTIVE ALGORITHM SHALL

COMPARE THE ZONE TEMPERATURE TO ITS SETPOINT AT THE BEGINNING OF

SCHEDULED OCCUPIED PERIOD AND SHALL AUTOMATICALLY ADAPT THE HEATING

OR COOLING RESPONSE TIME FOR THE NEXT UNOCCUPIED PERIOD. THE INITIAL

DEFAULT STARTING TIME PRIOR TO OCCUPANCY SHALL BE 60 MINS (ADJ).

ZONE TEMPERATURE AND AIRFLOW CONTROL

OCCUPIED ZONE TEMPERATURE:

UNITS SHALL RUN TO MAINTAIN THE FOLLOWING TEMPERATURES:

75°F (ADJ) COOLING SETPOINT

70°F (ADJ) HEATING SETPOINT

UNOCCUPIED ZONE TEMPERATURE:

UNITS SHALL RUN TO MAINTAIN THE FOLLOWING TEMPERATURES:

85°F (ADJ) COOLING SETPOINT

55°F (ADJ) HEATING SETPOINT

AIRFLOW SETPOINTS:

PROVIDE OPERATOR DEFINABLE, INDEPENDENT HEATING AND COOLING AIRFLOW

SETPOINTS PER VAV TERMINAL UNIT SCHEDULES.

SPACE CONDITION CONTROL:

THE TERMINAL UNIT (TU) SHALL MAINTAIN ZONE TEMPERATURE AND AIRFLOW SETPOINTS

BY CONTROLLING THE TU AIR DAMPER AND ZONE HEATING COIL VIA THE FOLLOWING:

OCCUPIED:

WHEN ZONE TEMPERATURE IS GREATER THAN ITS COOLING SETPOINT, THE ZONE DAMPER

SHALL MODULATE BETWEEN THE MINIMUM OCCUPIED AIRFLOW (ADJ) AND MAXIMUM

OCCUPIED AIRFLOW (ADJ) UNTIL ZONE TEMPERATURE IS SATISFIED. HEATING COIL VALVE

REMAINS CLOSED.

WHEN THE ZONE TEMPERATURE IS BETWEEN THE COOLING SETPOINT AND THE HEATING

SETPOINT, THE ZONE DAMPER SHALL MODULATE TO ITS MINIMUM OCCUPIED AIRFLOW

(ADJ). HEATING COIL VALVE REMAINS CLOSED.

VAV W/ REHEAT (VAV) : WHEN ZONE TEMPERATURE IS LESS THAN ITS HEATING SETPOINT,

THE CONTROLLER SHALL ENABLE THE HEATING COIL AND MODULATE THE HEATING COIL

VALVE TO MAINTAIN THE ZONE TEMPERATURE SETPOINT. THE HEATING AIRFLOW SHALL BE

LIMITED TO MINIMUM OCCUPIED AIRFLOW.

UNOCCUPIED:

THE TERMINAL UNITS SHALL CYCLE BETWEEN MINIMUM AND MAXIMUM AIRFLOW SETPOINTS

DURING UNOCCUPIED PERIODS. APPLY ± 3°F (ADJ) ALLOWABLE DRIFT FROM UNOCCUPIED

HEATING AND COOLING SETPOINTS AS DESCRIBED BELOW:

COOLING: WHEN CRITICAL ZONE (CZ) TEMPERATURE HAS RISEN ABOVE ITS UNOCCUPIED

SPACE TEMPERATURE COOLING SETPOINT PLUS THE DRIFT (3°F ADJ, AS STATED ABOVE),

THE AHU SHALL BEGIN STARTUP. THE CZ DAMPER SHALL OPEN TO ITS RESPECTIVE

MAXIMUM UNOCCUPIED COOLING MODE AIRFLOW SETPOINT AND REMAIN IN THIS POSITION

UNTIL THE ZONE TEMPERATURE IS AT SETPOINT MINUS THE DRIFT. THE ZONE CONTROLLER

SHALL THEN MODULATE THE ZONE DAMPER TO THE MINIMUM UNOCCUPIED COOLING MODE

AIRFLOW SETPOINT UNTIL CYCLE REPEATS.

HEATING: WHEN CRITICAL ZONE (CZ) TEMPERATURE HAS FALLEN BELOW ITS UNOCCUPIED

SPACE TEMPERATURE HEATING SETPOINT MINUS THE DRIFT, THE TU CONTROLLER SHALL

MODULATE THE ZONE DAMPER TO MINIMUM UNOCCUPIED HEATING MODE AIRFLOW

SETPOINT AND SHALL MODULATE THE HEATING COIL VALVE TO 100% OPEN. THIS SHALL

CONTINUE UNTIL ZONE TEMPERATURE IS AT SETPOINT PLUS THE DRIFT. THE ZONE

CONTROLLER SHALL THEN CLOSE THE HEATING COIL VALVE.

OVERRIDE: WHEN UNOCCUPIED MODE IS OVERRIDDEN BY USER AT LOCAL THERMOSTAT,

AHU IS TO ENERGIZE AND RUN IN OCCUPIED MODE FOR A 1 HOUR (ADJ) PERIOD BEFORE

RETURNING TO UNOCCUPIED MODE.

ALARMS AND SHUTDOWNS

NOTE: ALL ALARMS TO BE TIMESTAMPED ON BAS GRAPHIC

INTERFACE.

HIGH ZONE TEMPERATURE: IF THE ZONE TEMPERATURE IS GREATER

THAN THE COOLING SETPOINT BY 5°F (ADJ) FOR A MINIMUM OF 30

MINS (ADJ).

LOW ZONE TEMPERATURE: IF THE ZONE TEMPERATURE IS LESS

THAN THE HEATING SETPOINT BY 5°F (ADJ) FOR A MINIMUM OF 30

MINS (ADJ).

HIGH DISCHARGE AIR TEMPERATURE: IF THE TERMINAL UNIT

DISCHARGE AIR TEMPERATURE IS GREATER THAN 105°F (ADJ) FOR A

MINIMUM OF 30 MINS (ADJ).

HIGH AIRFLOW: IF THE ZONE AIRFLOW IS GREATER THAN THE

SETPOINT BY 25% (ADJ) FOR A MINIMUM OF 60 MINS (ADJ).

LOW AIRFLOW: IF THE ZONE AIRFLOW IS LESS THAN THE SETPOINT

BY 25% (ADJ) FOR A MINIMUM OF 60 MINS (ADJ).
