12.4 THE OUTSIDE AND EXHAUST AIR DAMPERS SHALL CLOSE AND THE RETURN AIR

DAMPER SHALL OPEN WHEN THE UNIT IS OFF.

13. HUMIDIFIER CONTROL

13.1 THE CONTROLLER SHALL MEASURE THE RETURN AIR HUMIDITY AND MODULATE

THE HUMIDIFIER TO MAINTAIN A SETPOINT OF 40% RH(ADJ.). THE HUMIDIFIER SHALL

BE ENABLED WHENEVER THE SUPPLY FAN STATUS IS ON AND THE OUTSIDE AIR

TEMPERATURE IS BELOW 65 DEGREES.

13.2 THE HUMIDIFIER SHALL TURN OFF WHENEVER: SUPPLY AIR HUMIDITY

MEASURERS 90% OR WHEN OUTSIDE AIR TEMPERATURE IS ABOVE 65 DEGREES OR

ON A LOSS OF SUPPLY FAN STATUS

13.3 ALARMS

HIGH SUPPLY AIR HUMIDITY 90%(ADJ)

LOW SUPPLY AIR HUMIDITY 30%(ADJ)

14. AIRFLOW CONTROL

14.1 THE CONTROL SYSTEM SHALL MONITOR AND DISPLAY SUPPLY AIR FLOW,

RETURN AIR FLOW, AND MIXED AIR FLOW IN CFM. IT WILL CALCULATE, AND DISPLAY

OUTDOOR AIR PERCENTAGE FROM THE MEASURED VALUES BASED ON THE

FOLLOWING FORMULA:

%OA = (RAT-MAT)/(RAT-OAT) X 100

14.2 THE MINIMUM OUTSIDE AIR DAMPER SHALL BE CONTROLLED AS FOLLOWS:

14.2.1 WHEN OUTSIDE AIR TEMPERATURE IS BELOW 50 DEGREES AND THE

ECONOMIZER CONTROL SEQUENCE HAS REDUCED THE OUTSIDE

18.2.7 FIVE MINUTES AFTER SUPPLY/RETURN FAN-ON STATUS HAS BEEN PROVEN,

OA FAN SHALL DELIVER 5% OF CFM RA AND EX DAMPERS SHOULD OPEN/CLOSE

SIMULTANEOUSLY WITH OA DAMPER. (OA=5% RA= 95% EX=5%).

18.2.8 FIVE MINUTES AFTER OA FAN STARTED DELIVERING 5%, RELEASE OA, RA,

RELIEF AIR DAMPERS TO CONTROL TO MEET MIXED AIR SETPOINT.

18.2.9 LOWER MIXED SET POINT TO 60 DEGREES FOR 10 MINUTES.

18.2.10 RELEASE MIXED AIR SET POINT BACK TO ORIGINAL SETTING.

AIRFLOW DOWN TO THE MINIMUM OUTSIDE AIR FLOW RATE, THE OUTSIDE AIR

DAMPER SHALL CLOSE TO THE MINIMUM POSITION.

14.2.2 WHEN THE AIR HANDLING UNIT CONTROLS ARE OPERATING IN ECONOMIZER

MODE, THE ECONOMIZER CONTROL SEQUENCE WILL MODULATE THE ECONOMIZER

DAMPER, WHILE THE OUTSIDE AIR DAMPER MAINTAINS MINIMUM OUTDOOR AIR

POSITION TO MAINTAIN THE MIXED AIR ECONOMIZER TEMPERATURE SETPOINT.

THE OUTSIDE AIR CALCULATION ABOVE IN 14.1 SHALL DISPLAY THE OUTSIDE AIR

PERCENTAGE BUT WILL NOT BE USED TO CONTROL THE OUTSIDE AIR DAMPER IN

THE ECONOMIZER MODE.

14.2.3 WHEN OUTSIDE AIR TEMPERATURE IS ABOVE 60 DEGREES AND THE

ECONOMIZER IS NOT ENABLED BASED ON THE OUTSIDE AIR TEMPERATURE OR

ENTHALPY PER 12.2 ABOVE, THE CONTROL SEQUENCE SHALL REDUCE THE

OUTSIDE AIRFLOW DOWN TO THE MINIMUM OUTSIDE AIR FLOW RATE. THE OUTSIDE

METER SHALL MEASURE THE OUTSIDE AIR FLOW. CALCULATION ABOVE IN 14.1

SHALL DISPLAY THE OUTSIDE AIR PERCENTAGE BUT WILL NOT BE USED TO

CONTROL THE OUTSIDE AIR DAMPER. WHEN THE OUTSIDE AIR TEMPERATURE AND

THE RETURN TEMPERATURE ARE EQUAL, ADJUST THE RETURN AIR TEMPERATURE

UPWARD BY 0.1 DEGREE F TO ENABLE THE OUTSIDE AIR CALCULATION TO

FUNCTION.

15. FILTERS

15.1 ALARMS

15.1.1 PREFILTER DIRTY -DIFFERENTIAL PRESSURE IS 1" GREATER THAN CLEAN

FILTER

15.1.2. FINAL FILTER DIRTY -DIFFERENTIAL PRESSURE IS 1" GREATER THAN CLEAN

FILTER

16. FAN HEAT OFFSET VALUE

16.1 FAN HEAT OFFSET (0-5)- THE BCS SHALL RESET THE FAN HEAT OFFSET VALUE

BASED UPON THE DIFFERENCE BETWEEN SUPPLY AIR SETPOINT AND SUPPLY AIR

TEMPERATURE. THE LOWER LIMIT SHALL BE 0. THE UPPER LIMIT SHALL BE 5.

16.2 WHEN SUPPLY AIR TEMPERATURE SENSOR INDICATES A TEMPERATURE OF 2°F

BELOW THE SUPPLY AIR SETPOINT, THE PID LOOP SHALL SUBTRACT 1 FROM THE

FAN HEAT OFFSET VALUE. IF THE FAN HEAT OFFSET VALUE IS GREATER THAN 0,

THEN THE FAN HEAT OFFSET SHALL BE SET TO 0. AFTER AN ADJUSTABLE PERIOD

OF 15 MINUTES THE PID LOOP SHALL COMPARE THE SUPPLY TEMPERATURE TO

THE SETPOINT AND ADJUST THE VALUE.

16.3 WHEN SUPPLY AIR TEMPERATURE SENSOR INDICATES A TEMPERATURE + OR -

2°F OF THE SUPPLY AIR SETPOINT, THE PID LOOP SHALL ADD ZERO TO THE FAN

HEAT OFFSET VALUE. AFTER AN ADJUSTABLE PERIOD OF 15 MINUTES THE PID

LOOP SHALL COMPARE THE SUPPLY TEMPERATURE TO THE SETPOINT AND ADJUST

THE VALUE.

16.4 WHEN SUPPLY AIR TEMPERATURE SENSOR INDICATES A TEMPERATURE OF 2°F

ABOVE THE SUPPLY AIR SETPOINT, THE PID LOOP SHALL ADD 1 TO THE FAN HEAT

OFFSET VALUE. IF THE FAN HEAT OFFSET VALUE IS GREATER THAN 5, THEN THE

FAN HEAT OFFSET SHALL BE SET TO 5. AFTER AN ADJUSTABLE PERIOD OF 15

MINUTES THE PID LOOP SHALL COMPARE THE SUPPLY TEMPERATURE TO THE

SETPOINT AND ADJUST THE VALUE.

17. CONTINUOUS COMMISSIONING ALARMS

17.1 IF IN COOLING MODE (OUTSIDE AIR IS GREATER THAN 50 DEGREES): PREHEAT

SECTION TEMP IS GREATER THAN MIXED AIR TEMPERATURE BY 1 DEG F, OR MORE,

THEN ALARM "STEAM VALVE OPEN IN COOLING MODE"

17.2 IF IN HEATING MODE (OUTSIDE AIR IS LESS THAN 50 DEGREES): COOLING

DISCHARGE TEMP IS LESS THAN PREHEAT TEMP BY 1 DEG F, OR MORE, THEN

ALARM "CHILLED WATER VALVE IS OPEN IN HEATING MODE"

18. COLD START SEQUENCE

18.1 WHENEVER UNIT IS STARTED AND OUTDOOR AIR TEMPERATURE IS BELOW 30

DEG F INITIATE THE FOLLOWING SEQUENCE.

18.2.1 OA DAMPER SHALL BE CLOSED (MIN OA FAN SHALL BE OFF), RELIEF AIR

DAMPER SHALL BE CLOSED, RETURN AIR DAMPER SHALL BE 100% OPEN

(ECONOMIZER DISABLED).

18.2.2 COMMAND ON STEAM PREHEAT VALVE.

18.2.3 STEAM PREHEAT VALVE SHALL MAINTAIN 80 DEGREE SUPPLY AIR

TEMPERATURE.

18.2.4 SMOKE DAMPER SHALL BE OPEN.

18.2.5 COMMAND ON SUPPLY AND RETURN (DRIVE) ALLOW TO RAMP UP NORMALLY.

18.2.6 SET MIXED AIR SETPOINT TO 70 DEG F ONCE SUPPLY/RETURN FAN ON

STATUS HAS BEEN PROVEN.
