- OUTSIDE AIR DAMPER- RELIEF/EXHAUST AIR DAMPER- OUTSIDE AIRFLOW MEASURING STATION FURNISHED BY AHU MANUFACTURER.

OCCUPIED MODE:PROGRAMMED OPERATING SCHEDULE SHALL BE COORDINATED WITH THE OWNER.

SUPPLY FANSTART/STOP: UPON RECEIVING A SIGNAL TO START, AFTER A 60 SECOND (ADJ) TIME DELAY TO ALLOW ASSOCIATED SMOKE DAMPERS TO OPEN, THE BAS SHALL START THE SUPPLY FAN VIA THE VFD. OUTSIDE AIR DAMPER SHALL OPEN TO ITS MINIMUM POSITION.

THE BAS SHALL VARY THE SPEED OF THE SUPPLY FAN VIA THE VFD TO MAINTAIN THE SUPPLY AIR STATIC PRESSURE SET POINT.

INSTALL A CURRENT STATUS SWITCH TO PROVE SUPPLY FAN OPERATION. LOCATE SWITCH SO IT CAN SENSE FAN OPERATION IN BOTH NORMAL AND BYPASS MODE OF THE VFD.

HIGH STATIC ALARM: INSTALL A PRESSURE SENSOR DOWNSTREAM OF THE SUPPLY FAN BEFORE ANY COILS, DAMPERS, FILTERS, ETC. THE PRESSURE SENSOR SHALL BE HARD WIRED TO THE SUPPLY FAN. IF THE STATIC PRESSURE EXCEEDS THE SET POINT OF 3” WC (ADJ), THE SUPPLY FAN SHALL SHUT-DOWN, REQUIRE A MANUAL RESET, AND AN ALARM SHALL BE SENT TO THE BAS.

UNOCCUPIED MODETHE UNIT SHALL CYCLE TO OCCUPIED MODE OPERATION EXCEPT AS NOTED HEREIN TO MEET THE UNOCCUPIED SPACE TEMPERATURE SET POINTS (78°F SUMMER AND 65°F WINTER). THE OUTSIDE AIR DAMPER SHALL BE FULLY CLOSED DURING ALL UNOCCUPIED HOURS EXCEPT WHEN OUTSIDE AIR ENTHALPY IS LOWER THAN RETURN AIR ENTHALPY WHICH WOULD ALLOW THE OUTSIDE AIR DAMPER TO MODULATE TO PROVIDE 55°F SUPPLY AIR.

MORNING WARM-UPENABLED AT OUTSIDE AIR TEMPERATURES BELOW 50°F (ADJ).

PRIOR TO OCCUPIED MODE BEING ENABLED, AT A TIME DETERMINED BY THE BMS BASED ON OUTSIDE AIR TEMPERATURE AND THE HISTORIC TIME IT TAKES THE INDIVIDUAL ZONES TO REACH OCCUPIED SPACE TEMPERATURE SET POINTS, THE UNIT SHALL ENTER THE MORNING WARM-UP MODE. IN THIS MODE, ALL VAV BOXES WHOSE SPACE TEMPERATURES ARE BELOW THE OCCUPIED HEATING SET POINT SHALL MODULATE THEIR DAMPERS FULLY OPEN. THE AIR HANDLING UNIT’S DISCHARGE SET POINT SHALL BE SET FOR 90°F. ONCE THE SPACE TEMPERATURE REACHES THE OCCUPIED MODE HEATING SET POINT, THE VAV BOXES DAMPERS SHALL MODULATE TO THEIR CLOSED POSITION. ONCE EVERY SPACE HAS REACHED ITS OCCUPIED MODE HEATING SET POINT OR MORE THAN 10% OF THE SPACES HAVE EXCEEDED THEIR COOLING MODE SET POINT, THE AIR HANDLING UNIT SHALL RETURN TO ITS NORMAL OCCUPIED MODE OPERATION.

FILTERSPROVIDE DIFFERENTIAL PRESSURE SENSORS ACROSS FILTER BANK.

PROVIDE AN ALARM TO THE OPERATOR’S WORKSTATION IF DIFFERENTIAL PRESSURE EXCEEDS SET POINT OF 0.75” WC (ADJ) FOR MERV-8 PRE-FILTERS.

SMOKE DETECTOR SAFETIESDUCT MOUNTED SMOKE DETECTORS SHALL BE HARDWIRED INDEPENDENT OF THE BMS TO DE-ENERGIZE SUPPLY AND RELIEF AIR FAN VFD'S AND CLOSE OUTSIDE AIR AND EXHAUST AIR DAMPERS AFTER 90 SECONDS (ADJ) DELAY.

COOLINGWHEN THE MIXED AIR TEMPERATURE SENSOR IS ABOVE SET POINT OF 52°F (ADJ), THE FOLLOWING SHALL OCCUR IN SEQUENCE:

THE HEATING CONTROL SHALL BE LOCKED OUT WHEN UNIT IS IN COOLING MODE.

IF OUTSIDE AIR TEMPERATURE IS LOWER THAN RETURN AIR TEMPERATURE, THE OUTSIDE AIR DAMPER SHALL MODULATE OPEN TO SATISFY SUPPLY AIR TEMPERATURE SENSOR SETPOINT OF 55°F (ADJ).

IF OUTSIDE AIR TEMPERATURE IS HIGHER THAN RETURN AIR TEMPERATURE, THE OUTSIDE AIR DAMPER SHALL MODULATE TO ITS MINIMUM POSITION.

HEATINGUPON A CALL FOR HEATING FROM THE SPACE THERMOSTAT, THE FOLLOWING SHALL OCCUR IN SEQUENCE:

OUTSIDE AIR DAMPER SHALL BE DRIVEN TO ITS MINIMUM POSITION

HOT WATER HEATING CONTROL VALVE SHALL OPEN TO ITS MINIMUM POSITION AND MODULATE TO MAINTAIN SPACE TEMPERATURE SETPOINT.
