VAV COOLING AND HEATING SEQUENCE OF OPERATIONS:
RUN CONDITIONS — SCHEDULED: THE UNIT SHALL RUN ACCORDING TO A USER DEFINABLE TIME SCHEDULE IN THE FOLLOWING MODES:
• OCCUPIED MODE: THE UNIT SHALL MAINTAIN;
A 74•F (ADJ.) COOLING SETPOINT AND A 70 -F (ADJ.)HEATING SETPOINT
• UNOCCUPIED MODE (NIGHT SET BACK): THE UNIT SHALL MAINTAIN:
A 82 -F (ADJ.) COOLING SETPOINT AND A 65-F (ADJ.) HEATING SETPOINT.
ZONE SETPOINT ADJUST /OPTIMAL START/ UNOCCUPIED OVERRIDE: THE OCCUPANT SHALL BE ABLE TO ADJUST THE ZONE TEMPERATURE HEATING
AND COOLING SETPOINTS AT THE ZONE SENSOR.THE UNIT 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
SCHEDULED OCCUPIED PERIOD.A 11MED LOCAL OVERRIDE CONTROL SHALL ALLOW AN OCCUPANT TO OVERRIDE THE SCHEDULE AND PLACE THE
UNIT INTO AN OCCUPIED MODE FOR AN ADJUSTABLE PERIOD OF TIME. AT THE EXPIRATION OF THIS TIME, CONTROL OF THE UNIT SHALL
AUTOMATICALLY RETURN TO THE SCHEDULE.
FLOW CONTROL: THE UNIT SHALL MAINTAIN ZONE SETPOINTS BY CONTROLLING THE AIRFLOW THROUGH ONE OF THE FOLLOWING:
OCCUPIED:
• WHEN ZONE TEMPERATURE IS GREATER THAN ITS COOLING SETPOINT, THE ZONE DAMPER SHALL MODULATE BETWEEN THE MINIMUM OCCUPIED
AIRFLOW (ADJ.) AND THE MAXIMUM COOLING AIRFLOW (ADJ.) UNTIL THE ZONE IS SATISFIED.
• WHEN THE ZONE TEMPERATURE IS BETWEEN THE COOLING SETPOINT AND THE HEATING SETPOINT, THE ZONE DAMPER SHALL MAINTAIN THE
MINIMUM REQUIRED ZONE VENTILATION (ADJ.).
• WHEN ZONE TEMPERATURE IS LESS THAN ITS HEATING SETPOINT, THE CONTROLLER SHALL ENABLE HEATING TO MAINTAIN THE ZONE
TEMPERATURE AT ITS HEATING SETPOINT.
UNOCCUPIED:
• WHEN THE ZONE IS UNOCCUPIED THE ZONE DAMPER SHALL CONTROL TO ITS MINIMUM UNOCCUPIED AIRFLOW (ADJ.).
• WHEN THE ZONE TEMPERATURE IS GREATER THAN ITS COOLING SETPOINT, THE ZONE DAMPER SHALL MODULATE BETWEEN THE MINIMUM
UNOCCUPIED AIRFLOW (ADJ.) AND THE MAXIMUM COOLING AIRFLOW (ADJ.) UNTIL THE ZONE IS SATISFIED.
• WHEN ZONE TEMPERATURE IS LESS THAN ITS UNOCCUPIED HEATING SETPOINT, THE CONTROLLER SHALL ENABLE HEATING TO MAINTAIN THE
ZONE TEMPERATURE AT THE SETPOINT.
ELECTRIC HEATING STAGES: THE CONTROLLER SHALL MEASURE THE ZONE TEMPERATURE AND STAGE THE REHEATING TO MAINTAIN ITS
SETPOINT. TO PREVENT SHORT CYCLING, THERE SHALL BE A USER DEFINABLE (ADJ.) DELAY BETWEEN STAGES, AND EACH STAGE
SHALL HAVE A USER DEFINABLE (ADJ.) MINIMUM RUNTIME.
DISCHARGE AIR TEMPERATURE: THE CONTROLLER SHALL MONITOR THE DISCHARGE AIR TEMPERATURE.
ALARMS SHALL BE PROVIDED AS FOLLOWS:
HIGH /LOW ZONE TEMP: IF THE ZONE TEMPERATURE IS GREATER/LOWER THAN THE COOLING SETPOINT BY A USER DEFINABLE AMOUNT
(ADJ.).

ZONE SETPOINT ADJUST /UNOCCUPIED OVERRIDE: THE OCCUPANT SHALL BE ABLE TO ADJUST THE ZONE TEMPERATURE SETPOINT AT THE ZONE
SENSOR.THE UNIT 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 SCHEDULED OCCUPIED PERIOD.A TIMED
LOCAL OVERRIDE CONTROL SHALL ALLOW AN OCCUPANT TO OVERRIDE THE SCHEDULE AND PLACE THE UNIT INTO AN OCCUPIED MODE FOR
AN ADJUSTABLE PERIOD OF TIME. AT THE EXPIRATION OF THIS TIME, CONTROL OF THE UNIT SHALL AUTOMATICALLY RETURN TO THE
SCHEDULE.

UNOCCUPIED:
• WHEN THE ZONE IS UNOCCUPIED THE ZONE DAMPER SHALL CONTROL TO ITS MINIMUM UNOCCUPIED AIRFLOW (ADJ.).
• WHEN THE ZONE TEMPERATURE IS GREATER THAN ITS COOLING SETPOINT, THE ZONE DAMPER SHALL MODULATE BETWEEN THE MINIMUM
UNOCCUPIED AIRFLOW (ADJ.) AND THE MAXIMUM COOLING AIRFLOW (ADJ.) UNTIL THE ZONE IS SATISFIED.
DISCHARGE AIR TEMPERATURE: THE CONTROLLER SHALL MONITOR THE DISCHARGE AIR TEMPERATURE.
ALARMS SHALL BE PROVIDED AS FOLLOWS:
HIGH /LOW ZONE TEMP: IF THE ZONE TEMPERATURE IS GREATER /LOWER THAN THE COOLING SETPOINT BY A USER DEFINABLE AMOUNT
