SINGLE DUCT AIR VOLUME CONTROL BOXES (CONSTANT)
GENERAL
- EACH CAV MUST HAVE AN INDIVIDUALLY RE-PROGRAMMABLE OCCUPANCY SCHEDULE.
- ALL CAVS MUST HAVE CROSS FLOW AIR FLOW SENSORS, CONTROL TRANSFORMER, DAMPER AND TERMINAL STRIP PROVIDED BY CAV MANUFACTURER.
- CONTROLS CONTRACTOR MUST DELIVER DDC CONTROLLER, DAMPER ACTUATOR, AND ALL REQUIRED ACCESSORIES TO CAV MANUFACTURER FOR
FACTORY INSTALLATION. CONTROLS CONTRACTOR MUST COORDINATE WITH CAV MANUFACTURER AND PROVIDE ALL NECESSARY MATERIALS.

UNOCCUPIED MODE
• UPON A RISE IN SPACE TEMPERATURE ABOVE UNOCCUPIED COOLING SETPOINT (80°F. ADJUSTABLE), THE DDC SYSTEM ENERGIZES THE ASSOCIATED AHU IN UNOCCUPIED MODE TO MAINTAIN SPACE
TEMPERATURE 5°F BELOW UNOCCUPIED COOLING SETPOINT.
• UPON A DROP IN SPACE TEMPERATURE BELOW UNOCCUPIED HEATING SETPOINT (58°F. ADJUSTABLE), THE DDC SYSTEM ENERGIZES THE ASSOCIATED AHU IN UNOCCUPIED MODE. REHEAT CONTROL
VALVE MODULATES TO MAINTAIN SPACE TEMPERATURE 5°F ABOVE UNOCCUPIED HEATING SETPOINT.
SAFETIES AND ALARMS
• ALL ZONE TEMPERATURES ARE MONITORED AND ALARMED BY THE BAS. AN ALARM IS ANNUNCIATED TO THE BAS IF ZONE TEMPERATURE RISES ABOVE 80°F OR DROPS BELOW 65°F DURING THE
OCCUPIED MODE.

UNIT HEATER (UH) CONTROL SEQUENCE
GENERAL
- THE DDC SYSTEM WILL ENABLE THE UNIT HEATER WHENEVER OUTDOOR AIR TEMPERATURE FALLS
BELOW SETPOINT (50°F. ADJUSTABLE).
- THE UNIT FAN MUST RUN ONLY ON A CALL FOR HEAT.

HEATING TEMPERATURE SETPOINT (60°F. ADJUSTABLE).

GENERAL
• EACH CHILLED BEAM TEMPERATURE ZONE HAS A 2-WAY MODULATING COOLING CONTROL VALVE, A WALL-MOUNTED TEMPERATURE/HUMIDITY SENSOR AND A DUCT-MOUNTED VARIABLE AIR VOLUME (VAV) BOX.
• PROVIDE ZONE SENSORS WITH SET POINT ADJUSTMENT AND DISPLAY CAPABILITY IN OFFICES, ALL OTHER ZONES HAVE DISPLAY WITH NO SET POINT ADJUSTMENT. SPACE SET POINTS ARE:
• OCCUPIED MODE: 75°F COOLING / 68°F HEATING
• UNOCCUPIED MODE: 80°F COOLING / 58°F HEATING
• HEATING IS PROVIDED THROUGH EITHER FIN TUBE RADIATION OR A BOX-MOUNTED HEATING COIL DEPENDING ON ZONE.
OCCUPIED MODE
• UPON A RISE IN SPACE TEMPERATURE ABOVE COOLING SET POINT, COOLING CONTROL VALVE MODULATES OPEN. UPON A DROP IN SPACE TEMPERATURE BELOW COOLING SET POINT, THE REVERSE OCCURS.
• WHEN SPACE TEMPERATURE IS BETWEEN HEATING AND COOLING SET POINT, CONTROL VALVE IS CLOSED.
• WHEN ZONE IS IN HEATING MODE, COOLING CONTROL VALVE IS CLOSED. UPON A DROP IN SPACE TEMPERATURE BELOW HEATING SET POINT, FIN TUBE OR REHEAT CONTROL VALVE OPENS.
UNOCCUPIED CONTROL DURING BUILDING OCCUPIED MODE
• OCCUPIED/UNOCCUPIED SWITCH OVER: PROVIDE CONNECTION TO OCCUPANCY SENSOR PROVIDED BY ELECTRICAL CONTRACTOR IN EACH SPACE ASSOCIATED WITH THE VAV BOX SERVING THAT TEMPERATURE ZONE.
• IF ALL SPACES ASSOCIATED WITH THE TEMPERATURE ZONE ARE UNOCCUPIED, AS INDICATED BY THE OCCUPANCY SENSOR, THE BAS OVERRIDES THE OCCUPANCY MODE AS FOLLOWS:
• THE MINIMUM AIRFLOW SET POINT IS SET TO THE SCHEDULED “UNOCCUPIED AIRFLOW” AND THE CHILLED BEAM CONTROL VALVE CLOSES.
• IN THE EVENT THE SPACE TEMPERATURE RISES ABOVE THE COOLING SET POINT, THE VAV BOX IS INDEXED TO THE SCHEDULED COOLING AIRFLOW RATE AND CHILLED BEAM CONTROL VALVE MODULATES OPEN.
• IN THE EVENT THE SPACE TEMPERATURE DROPS BELOW THE HEATING SET POINT, THE ZONE HEATING VALVE MODULATES OPEN.
• WHEN THE OCCUPANCY SENSOR SIGNALS THE ZONE IS OCCUPIED, AND AFTER A 2 MINUTE (ADJUSTABLE) TIME DELAY, THE VAV BOX OPENS TO PROVIDE SCHEDULED COOLING AIR FLOW AND THE ZONE REVERTS TO
OCCUPIED MODE.
• ALL PROGRAMMING FOR THE ABOVE SEQUENCE RESIDES IN THE LOCAL DDC CONTROLLER; THE SUPERVISORY CONTROLLER IS NOT REQUIRED TO RESET ANY FLOW OR TEMPERATURE SET POINTS BASED ON THE
OCCUPANCY SENSOR.
BUILDING UNOCCUPIED MODE
• CHILLED BEAM SYSTEM IS DISABLED DURING THE BUILDING UNOCCUPIED MODE AND ALL CHILLED BEAM CONTROL VALVES AND VAV DAMPERS ARE CLOSED.
• UPON A CALL FOR COOLING OR DEHUMIDIFICATION, ALL ASSOCIATED SYSTEM VAV BOXES OPEN AND CHILLED BEAM CONTROL VALVES OPERATE IN ACCORDANCE WITH OCCUPIED MODE SEQUENCE.
SAFETIES AND ALARMS
• PROVIDE A CONDENSATION DETECTOR FOR EACH CHILLED BEAM ZONE. IF ONE CHILLED BEAM ZONE SERVES MULTIPLE ROOMS, PROVIDE ONE DETECTOR PER ROOM. UPON SENSING CONDENSATION, AN ALARM IS
ANNUNCIATED TO THE BAS SENT AND THE ASSOCIATED CHILLED BEAM CONTROL VALVE CLOSES. ASSOCIATED VAV BOX IS INDEXED TO SCHEDULED COOLING AIR FLOW RATE.
• PROVIDE TEMPERATURE AND HUMIDITY SENSORS FOR MONITORING AND CONTROL PURPOSES IN EACH ZONE. AN ALARM IS ANNUNCIATED TO THE BAS IF DEW POINT EXCEEDS 58°F (ADJUSTABLE).
• ALL ZONE TEMPERATURES ARE MONITORED AND ALARMED BY THE BAS. AN ALARM IS ANNUNCIATED TO THE BAS IF ZONE TEMPERATURE RISES ABOVE 80°F OR DROPS BELOW 65°F DURING THE OCCUPIED MODE.
• AN ALARM IS ANNUNCIATED TO THE BAS IF ZONE CO2 EXCEEDS 1,000 PPM (ADJUSTABLE).
