6. ALL SYSTEM FIRE/SMOKE DAMPERS SHALL BE HARD-WIRE INTERLOCKED SUCH THAT THEY CLOSE FULLY WHEN RTU FANS STOP.

7. EACH OF THE TWO RTU SUPPLY FANS AND TWO RTU RETURN FANS (SERVING RTU-N-2 AND RTU-N-4) AND ALL THREE REMOTE EXHAUST FANS [(E) EF-R-2, (E) EF-R-3; EF-R-4] SHALL EACH HAVE A CURRENT SENSOR FOR STATUS. IF ANY OF THE RTU SUPPLY AND RETURN FAN STATUS POINTS OR ANY OF THE THREE REMOTE EXHAUST FANS INDICATE OFF, A HARDWIRED INTERLOCK CAUSES THE OTHER FANS TO GO OFF, OUTSIDE AND RELIEF AIR DAMPERS TO CLOSE, RETURN AIR DAMPER TO OPEN, FIRE/SMOKE DAMPERS TO CLOSE, AND EACH EXHAUST FAN SHUTOFF DAMPER TO CLOSE.

8. CONTROL SUBMITTALS INCLUDING DRAWINGS, SCHEDULES, SEQUENCES OF OPERATION, ETC., FOR ALL DDC CONTROLLED EQUIPMENT SHALL BE STORED AND ACCESSIBLE ON THE GRAPHICS SO THEY ARE ALWAYS AVAILABLE AND NOT LOST.

B. SETPOINTS:

1. ALL SETPOINTS GIVEN IN THE SEQUENCE OF OPERATIONS OR IN THE DRAWINGS ARE FOR SYSTEM STARTUP AND ARE

PRELIMINARY AND SHALL BE ADJUSTABLE.

2. ALL SETPOINTS SHALL BE ACCESSIBLE TO THE OWNER SO SYSTEM CAN BE TESTED. SETPOINTS AND SCREENS SHOULD HAVE UNIQUE PASSWORD PROTECTION CAPABILITY SHOULD THE OWNER DECIDE TO LIMIT ACCESSIBILITY. COORDINATE

ACCESSIBILITY AND GRAPHICS SETUP WITH OWNER BEFORE FINAL IMPLEMENTATION.

3. OPTIMUM OPERATING SETPOINTS MUST BE DETERMINED DURING ACTUAL OCCUPANCY AND WILL BE AFFECTED BY MANY

FACTORS. THESE MAY INCLUDE:

A. WEATHER CONDITIONS.

B. BUILDING OCCUPANCY.

C. BUILDING UTILIZATION PATTERNS.

D. VARIATIONS IN BUILDING CONSTRUCTION.

E. VARIATIONS IN OPERATING CHARACTERISTICS OF ACTUAL INSTALLED BUILDING EQUIPMENT.

IT IS THE RESPONSIBILITY OF THE BUILDING OPERATORS TO DETERMINE THOSE SETTINGS AND OPERATING METHODS WHICH PROVIDE THE BEST BALANCE OF OPERATING EFFICIENCY AND OCCUPANT COMFORT. THIS IS AN ONGOING PROCESS. OPTIMUM

SETTINGS CHANGE AS OPERATING CONDITIONS CHANGE.

C. RTU-N-2 AND RTU-N-4 AND REMOTE EXHAUST FANS (E) EF-R-2, (E) EF-R-3, AND EF-R-4

1. GENERAL:

A. RTU SUPPLY, RETURN, AND REMOTE EXHAUST FANS SHALL EACH BE INTERLOCKED THROUGH A DAMPER END SWITCH, SO

EACH CANNOT START UNTIL ITS RESPECTIVE OUTSIDE, RELIEF, EXHAUST SHUTOFF AND COMBINATION FIRE/SMOKE DAMPERS ARE FULLY OPEN. IF AN END SWITCH IS NOT SATISFIED WITHIN 10 MINUTES, (ADJUSTABLE), GENERATE A UNIQUE

END SWITCH ALARM IDENTIFYING WHICH END SWITCH WAS NOT SATISFIED.

B. THE RTU’S OCCUPIED, UNOCCUPIED, PRE-OCCUPANCY TIME PERIOD IS DETERMINED BY A TIME SCHEDULE AND

PROGRAMMING.

2.UNOCCUPIED MODE:

A. DURING UNOCCUPIED MODE, THE RTU IS OFF UNLESS THERE IS A CALL FOR HEATING OR COOLING OR DEHUMIDIFICATION TO

MAINTAIN UNOCCUPIED SPACE SETPOINTS OR FOR UNOCCUPIED MORNING WARM-UP OR COOL-DOWN CYCLE. WHEN THE RTU IS OFF, SUPPLY FAN, RETURN FAN, AND REMOTE EXHAUST FANS ARE OFF, AND ALL DAMPERS AND VALVES GO TO

NORMAL POSITIONS AS SHOWN ON THE RTU AND REMOTE EXHAUST FAN CONTROL SCHEMATICS.

B. UNOCCUPIED SPACE SETPOINTS ARE AS FOLLOWS:

UNOCCUPIED HEATING SETPOINT 62°F, (ADJUSTABLE).

UNOCCUPIED COOLING SETPOINT 80°F, (ADJUSTABLE).

WHENEVER RTU IS STARTED TO MAINTAIN UNOCCUPIED SPACE SETPOINTS, IT BEHAVES AS IF IN OCCUPIED MODE EXCEPT IN FULL RETURN MODE WITH RETURN FAN TRACKING SUPPLY AT A REDUCED SPEED DIFFERENTIAL DETERMINED BY BALANCER, OUTDOOR AND RELIEF AIR DAMPERS ARE CLOSED, AND REMOTE EXHAUST FANS REMAIN OFF. IF ECONOMIZER CAN BE USED, RTU IS CONTROLLED AS IT WOULD BE IN OCCUPIED MODE UNTIL SETPOINT IS SATISFIED. WHEN

UNOCCUPIED SPACE SETPOINTS ARE SATISFIED, THE RTU WILL STOP.

C) UNOCCUPIED HEATING SETBACK MODE IS MAINTAINED AS FOLLOWS: IF ANY SPACE SENSOR READS BELOW THE UNOCCUPIED HEATING SETPOINT, THE RTU WILL BE STARTED AND RUN UNTIL ALL UNOCCUPIED HEATING SPACE SETPOINTS ARE SATISFIED. THE RTU MIXING DAMPERS WILL MODULATE TO FULL RETURN MODE TO MAINTAIN THE HIGHEST SUPPLY AIR TEMPERATURE SETPOINT POSSIBLE. TERMINAL UNITS IN UNSATISFIED SPACES WILL BEHAVE AS IF IN OCCUPIED MODE UNTIL

SETPOINT IS SATISFIED.

D) UNOCCUPIED COOLING SETUP MODE IS MAINTAINED AS FOLLOWS: IF ANY SPACE SENSOR READS ABOVE THE UNOCCUPIED COOLING SETPOINT, THE RTU WILL BE STARTED AND RUN UNTIL ALL UNOCCUPIED COOLING SPACE SETPOINTS ARE SATISFIED. THE RTU COOLING COIL VALVE WILL MODULATE OPEN TO MAINTAIN THE RTU SUPPLY AIR TEMPERATURE SETPOINT. TERMINAL UNITS IN UNSATISFIED SPACES WILL BEHAVE AS IF IN OCCUPIED MODE UNTIL SETPOINT IS SATISFIED.

IF ECONOMIZER CAN BE USED, RTU IS CONTROLLED AS IT WOULD BE IN OCCUPIED MODE UNTIL SETPOINT IS SATISFIED.

3. PRE-OCCUPANCY OPTIMUM START MODE:

A. PRE-OCCUPANCY OPTIMUM START MODE IS INITIALLY SCHEDULED, AND THE SCHEDULED START TIME IS OPTIMIZED BASED

ON INSIDE AND OUTSIDE AIR TEMPERATURE AND SYSTEM HISTORY OF PERFORMANCE. THE DDC CONTROLLER CALCULATES THE OPTIMUM PRE-OCCUPANCY MODE HEATING/COOLING TIME NECESSARY TO BRING BUILDING TO OCCUPIED

TEMPERATURE IN EITHER WARM-UP OR COOL-DOWN CYCLES.

B. UPON INITIATION OF A START IN PRE-OCCUPANCY OPTIMUM START MODE (WARM-UP OR COOL-DOWN CYCLE), THE

FOLLOWING EVENTS OCCUR:

1. OPEN RETURN AIR DAMPER UNLESS SYSTEM DETERMINES ECONOMIZER CAN BE USED FOR COOL-DOWN CYCLE.

2. OPEN FIRE/SMOKE DAMPERS.

3. OUTSIDE AND RELIEF AIR DAMPERS SHALL REMAIN CLOSED UNLESS SYSTEM DETERMINES ECONOMIZER CAN BE USED

FOR COOL-DOWN CYCLE.

4. REMOTE EXHAUST FANS SHALL REMAIN OFF UNLESS SYSTEM DETERMINES ECONOMIZER CAN BE USED FOR COOL-DOWN

CYCLE.

5. WHEN RTU RETURN AND FIRE/SMOKE DAMPERS ARE FULLY OPEN, END SWITCHES SHALL ALLOW RTU SUPPLY AND

RETURN FANS TO START WITH RETURN FAN TRACKING SUPPLY FAN AT REDUCED SPEED DIFFERENTIAL DETERMINED BY BALANCER UNLESS ECONOMIZER CAN BE USED. IF ECONOMIZER CAN BE USED, RETURN FAN IS CONTROLLED AS IT WOULD

BE IN OCCUPIED MODE.

C) PRE-OCCUPANCY WARM-UP CYCLE: DURING PRE-OCCUPANCY MODE, THE DDC SYSTEM OPERATES THE UNIT IN ITS WARM- UP CYCLE IF THE AVERAGE SPACE TEMPERATURE OF THE VAV BOX ZONES SERVED BY THE RTU IS BELOW 72°F

(ADJUSTABLE). THE FOLLOWING EVENTS OCCUR DURING PRE-OCCUPANCY WARM-UP CYCLE:

1. OUTSIDE AND RELIEF AIR DAMPERS ARE CLOSED.

2. RETURN AIR DAMPER AND FIRE/SMOKE DAMPERS ARE OPEN.

3. REMOTE EXHAUST FANS ARE OFF.

4. RTU COOLING COIL VALVE IS CLOSED TO COIL.

5. THE RTU MIXING DAMPERS WILL MODULATE TO FULL RETURN MODE TO MAINTAIN THE SUPPLY AIR TEMPERATURE

SETPOINT. SUPPLY FAN WILL MODULATE TO MAINTAIN SUPPLY DUCT STATIC PRESSURE AT SETPOINT. RETURN FAN WILL

TRACK SUPPLY FAN BY A REDUCED SPEED DIFFERENTIAL DETERMINED BY BALANCER.

6. TERMINAL UNITS WILL BEHAVE AS IF IN OCCUPIED MODE UNTIL EACH OCCUPIED SPACE SETPOINT IS SATISFIED.

7. WARM-UP MODE IS TERMINATED WHEN THE RTU IS INDEXED TO ITS OCCUPIED MODE TIME PERIOD, OR WHEN ALL SPACES

REACH THEIR OCCUPIED HEATING SPACE TEMPERATURE SETPOINTS BEFORE OCCUPIED MODE TIME PERIOD BEGINS. SEE

OCCUPIED MODE SEQUENCE FOR OCCUPIED SPACE TEMPERATURE SETPOINTS.

D) PRE-OCCUPANCY COOL-DOWN CYCLE: DURING PRE-OCCUPANCY MODE, THE DDC SYSTEM OPERATES THE UNIT IN ITS COOL- DOWN CYCLE IF THE AVERAGE SPACE TEMPERATURE OF THE VAV BOX ZONES SERVED BY THE UNIT IS ABOVE 75°F

(ADJUSTABLE). THE FOLLOWING EVENTS OCCUR DURING PRE-OCCUPANCY COOL-DOWN CYCLE:

1. OUTSIDE AND RELIEF AIR DAMPERS ARE CLOSED UNLESS SYSTEM DETERMINES ECONOMIZER CAN BE USED FOR COOL-

DOWN CYCLE.

2. RETURN AIR DAMPER IS OPEN UNLESS SYSTEM DETERMINES ECONOMIZER CAN BE USED FOR COOL-DOWN CYCLE.

3. FIRE/SMOKE DAMPERS ARE OPEN.

4. REMOTE EXHAUST FANS ARE OFF UNLESS SYSTEM DETERMINES ECONOMIZER CAN BE USED FOR COOL-DOWN CYCLE.

5. THE RTU MIXING DAMPERS WILL MODULATE TO FULL RETURN MODE, UNLESS SYSTEM DETERMINES ECONOMIZER CAN BE

USED FOR COOL-DOWN CYCLE, AND THE RTU COOLING COIL VALVE WILL MODULATE OPEN TO MAINTAIN THE RTU SUPPLY

AIR TEMPERATURE SETPOINT.

6. SUPPLY FAN WILL MODULATE TO MAINTAIN RESET SUPPLY DUCT STATIC PRESSURE AT SETPOINT AS IT WOULD IN OCCUPIED MODE. SEE SUPPLY DUCT STATIC PRESSURE RESET SCHEDULE IN OCCUPIED MODE SEQUENCES.

7. RETURN FAN WILL TRACK SUPPLY FAN AT A REDUCED SPEED DETERMINED BY BALANCER UNLESS ECONOMIZER CAN BE USED. IF ECONOMIZER CAN BE USED, RETURN FAN IS CONTROLLED AS IT WOULD BE IN OCCUPIED MODE.

8. TERMINAL UNITS WILL BEHAVE AS IF IN OCCUPIED MODE UNTIL EACH OCCUPIED SPACE SETPOINT IS SATISFIED.

9. COOL-DOWN MODE IS TERMINATED WHEN THE UNIT IS INDEXED TO ITS OCCUPIED MODE TIME PERIOD, OR WHEN ALL

SPACES REACH THEIR OCCUPIED COOLING SPACE TEMPERATURE SETPOINTS BEFORE OCCUPIED MODE TIME PERIOD

BEGINS. SEE OCCUPIED MODE SEQUENCE FOR OCCUPIED SPACE TEMPERATURE SETPOINTS.

6. RETURN FAN SPEED SHALL BE CONTROLLED TO MAINTAIN RETURN FAN DISCHARGE STATIC PRESSURE AT SETPOINT. THE SETPOINT SHALL BE RESET LINEARLY FROM RFSPMIN (RETURN FAN STATIC PRESSURE MINIMUM) TO RFSPMAX. SETPOINTS

ARE DETERMINED IN CONJUCTION WITH THE AIR BALANCER AS FOLLOWS:

A. RFSPMIN: STATIC PRESSURE SETPOINT REQUIRED TO DELIVER THE DESIGN RETURN AIR VOLUME ACROSS THE RETURN AIR DAMPER WHEN THE SUPPLY AIR FAN IS AT DESIGN AIRFLOW AND ON MINIMUM OUTDOOR AIR. THIS SETPOINT SHALL

BE NO LESS THAN 0.01 INCHES (ADJUSTABLE) TO MAINTAIN POSITIVE DISCHARGE FLOW.

B. RFSPMAX: STATIC PRESSURE SETPOINT REQUIRED TO EXHAUST ENOUGH AIR TO MAINTAIN BUILDING STATIC PRESSURE AT SETPOINT OF 0.05 INCHES (ADJUSTABLE) WHEN THE SUPPLY AIR FAN IS AT DESIGN AIRFLOW AND ON 100% OUTDOOR

AIR.

BUILDING PRESSURIZATION CONTROL LOOP:

7. EXHAUST DAMPERS SHALL ONLY BE ENABLED WHEN THE ASSOCIATED SUPPLY AND RETURN FANS ARE PROVEN ON AND THE MINIMUM OUTDOOR AIR DAMPER IS OPEN. THE EXHAUST DAMPERS SHALL BE CLOSED WHEN RTU IS DISABLED.

8. EXHAUST DAMPERS ARE CONTROLLED TO MAINTAIN BUILDING PRESSURE DIRECTLY USING A DIFFERENTIAL PRESSURE SENSOR WITH PRESSURE SENSOR PICKUP PROBE(S) LOCATED IN A REPRESENTATIVE SPACE INSIDE THE BUILDING AND PRESSURE SENSOR PICKUP PROBE(S) LOCATED OUTDOORS. SEE AIR BALANCE SCHEDULES FOR RELIEF REQUIRED FOR

BUILDING AIR BALANCE.

9. BUILDING STATIC PRESSURE SHALL BE TIME AVERAGED WITH A SLIDING 5-MINUTE (ADJUSTABLE) WINDOW TO DAMPEN

FLUCTUATIONS. THE AVERAGED VALUE SHALL BE THAT DISPLAYED AND USED FOR CONTROL.

10. DUE TO THE POTENTIAL FOR INTERACTION BETWEEN THE BUILDING PRESSURIZATION AND RETURN FAN CONTROL LOOPS, EXTRA CARE MUST BE TAKEN IN SELECTING CONTROL LOOP GAINS. TO PREVENT EXCESSIVE CONTROL LOOP INTERACTION,THE CLOSED LOOP RESPONSE TIME OF THE BUILDING PRESSURIZATION LOOP SHOULD NOT EXCEED 1/5 OF THE CLOSED LOOP RESPONSE TIME OF THE RETURN FAN CONTROL LOOP. THIS CAN BE ACCOMPLISHED BY DECREASING THE GAIN OF THE BUILDING PRESSURIZATION CONTROLLER. IN OTHER WORDS, THE BUILDING PRESSURE CONTROL LOOP MUST BE VERY SLOW RELATIVE TO THE RETURN FAN CONTROL LOOP, AND THE BUILDING PRESSURE CONTROL POINT SHOULD NOT BE THE REALTIME DIFFERENTIAL PRESSURE READING BUT INSTEAD A MOVING AVERAGE OF THE DIFFERENTIAL PRESSURE READING TO PREVENT SPIKES FROM CAUSING RELIEF DAMPER COTNROL INSTABILITY.

11. WHEN EXHAUST DAMPERS ARE ENABLED, A CONTROL LOOP SHALL MODULATE EXHAUST DAMPERS TO MAINTAIN THE BUILDING PRESSURE AT A SETPOINT OF 0.05 INCHES (ADJUSTABLE). THE RANGE OF THE SENSOR MAY BE AS LOW AS +0.1 INCHES (ADJUSTABLE) BUT SPIKES DUE TO WIND AND OTHER FACTORS MAY CAUSE A HIGHER RANGE OF PRESSURES TO
