STEAM HUMIDIFIER:

RETURN (OR EXHAUST) AIR HUMIDITY SHALL BE MONITORED.

ON A CALL FOR HUMIDIFICATION, HUMIDIFIER VALVE V-2/1 SHALL OPEN AND MODULATE TO

MAINTAIN THE RETURN (OR EXHAUST) AIR HUMIDITY SET POINT TO 30% (ADJUSTABLE).

ON CALL FOR ADDITIONAL HUMIDITY VALVE V-2/2 SHALL OPEN AND MODULATE TO

MAINTAIN THE HUMIDITY.

PRIOR TO ACTIVATION OF V-2/1, THE ON/OFF CONTROL VALVE V-0 SHALL BE ENABLED

THROUGH ECC AND JACKET TEMPERATURE SENSED BY TSH SHALL BE WARM ENOUGH TO

PREVENT CONDENSATION.

THE AIRFLOW SWITCH SHALL PROVE AIRFLOW BEFORE HUMIDITY CONTROLS ARE

ACTIVATED.

SEQUENCE OF OPERATION FOR RTU:

1. GENERAL:

1.1. THE UNIT SHALL OPERATE 24/7.

1.2. H-O-A SWITCH SHALL BE KEPT IN “AUTO” POSITION AND “OFF” POSITION SHALL BE USED ONLY FOR MAINTENANCE.

1.3. WHEN THE UNIT IS OFF DAMPERS D-1, AND D-2 SHALL CLOSE AND STATUS SHALL BE AVAILABLE ON THE BMS SYSTEM VIA ACTUATOR END SWITCHES.

1.4. WHEN UNIT IS COMMANDED ON, DAMPERS D-1, AND D-2 SHALL OPEN (STATUS INDICATED ON BMS VIA END SWITCHES). AFTER SAFETIES CHECK UNIT SHALL START.

2. TEMPERATURE CONTROL:

2.1. SUPPLY AIR TEMPERATURE AND HUMIDITY SETPOINT (AS SET BY BMS), SET BY SENSOR TT-8 AND HT-4, SHALL BE MAINTAINED BY SEQUENCING VALVES V-1, V-2, AND V-3. VALVES SHALL OPEN BASED ON SUPPLY AIR CONDITIONS AND SHALL NOT OPEN SIMULTENOUSLY.

3. AIRFLOW CONTROL:

3.1. THE SUPPLY AIR FLOW SHALL BE CONTROLLED BY THE BMS, MODULATING THE SUPPLY FAN VFD TO MAINTAIN SUPPLY STATIC PRESSURE SENSED BY SPS-1.

3.2. THE SPACES SERVED BY RTU SHALL BE MAINTAINED AT PRESSURE DIFFERENTIAL AS INDICATED ON THE DRAWINGS. CONTRACTOR SHALL PROVIDE TWO NEW

DIFFERENTIAL PRESSURE SENSORS TO MONITOR PRESSURE DIFFERENCE BETWEEN CLEAN STORAGE AND WAREHOUSE AND BREAK OUT ROOM.

3.3. THE EXHAUST VALVES SHALL TRACK SUPPLY VAVS AND SHALL MAINTAIN SPACE PRESSURES AS INDICATED ON THE DRAWINGS.

3.4. THE SUPPLY FAN AND RETURN AIR FAN TOTAL AIR FLOW SHALL BE TRACKED, AS SENSED BY AFT-3 AND AFT-4, TO MAINTAIN SPACE PRESSURIZATION.

3.5. THE HIGH-PRESSURE SENSOR PSH SHALL PREVENT SUPPLY AIR FAN DEVELOPING OVER 3” STATIC PRESSURE. THE SENSOR SHALL BE HARD WIRED TO SUPPLY FAN

MOTOR. IF HIGHER PRESSURE IS DEVELOPED, THE FAN SHALL SHUT OFF. UNIT SHALL BE MANUALLY RESTARTED.

3.6. THE LOW-PRESSURE SENSOR PSL SHALL PREVENT RETURN AIR FAN FROM DEVELOPING OVER 3” OF NEGATIVE STATIC PRESSURE. THE SENSOR SHALL BE HARD

WIRED TO RETURN FAN MOTOR. IF HIGHER NEGATIVE PRESSURE IS DEVELOPED, THE FAN SHALL SHUT OFF. UNIT SHALL BE MANUALLY RESTARTED.

4. HUMIDITY CONTROL:

4.1. THE SUPPLY AIR, RETURN AIR, AND OUTSIDE AIR RELATIVE HUMIDITY SHALL BE COMPARED AND ACCORDINGLY, HUMIDITY IN SUPPLY AIR SHALL BE ADDED.

4.2. ON CALL FOR HUMIDITY INCREASE THE CONTROL VALVE V-2 AT HUMIDIFIER SHALL OPEN AND STEAM SHALL BE DISPERSED INTO THE AIR STREAM IN THE HUMIDIFIER

SECTION.

4.3. WHEN RETURN AIR DEW POINT IS HIGHER THAN 45 DEGREES F. (ADJ), VALVE V-2 SHALL CLOSE AND NO STEAM INJECTION WILL BE DONE.

4.4. FOR DEHUMIDIFICATION, TERMINAL REHEAT COILS SHALL BE USED TO MAINTAIN THE SPACE CONDITIONS.

5. FREEZE PROTECTION:

5.1. IF THE AIR TEMPERATURE AS SENSED BY TT-5 FALLS BELOW 40 DEGREES F. (ADJ), AN ALARM WILL BE GENERATED AT THE BMS FRONT END.

5.2. THE FREEZESTAT SHALL BE SET AT 32 F (ADJ). IF THE AIR TEMPERATURE FALLS BELOW 32 F (ADJ) THE UNIT SUPPLY AND RETURN FANS SHALL BE DE-ENERGIZED.

UNIT WILL SHUT OFF AND DAMPERS D-1 AND D-2 SHALL CLOSE. UNIT SHALL BE MANUALLY RESTARTED.

5.3. DURING NO-FLOW CONDITIONS AS SENSED BY FLOW TRANSMITTER FT-1 AND WHEN AIR TEMPERATURE AS SENSED BY TT-5 IS BELOW 35 DEGREES F. (ADJ), THE UNIT

WILL SHUT OFF AS STATED ABOVE. UNIT SHALL BE MANUALLY RESTARTED.

5.4. IF NO WATER FLOW IS DETECTED ON CALL FOR HEATING AS SENSED BY FT-1, AN ALARM WILL BE GENERATED AND ABOVE FREEZE PROTECTION SEQUENCE SHALL BE

FOLLOWED.

6. LOSS OF COOLING PROTECTION:

6.1. IF THE SUPPLY AIR TEMPERATURE AS SENSED BY TT-8 IS ABOVE 65 DEGREES F. (ADJ), AN ALARM WILL BE GENERATED AT THE BMS FRONT END. IF THE TEMPERATURE

RISES TO 70 DEGREES F. (ADJ), THE UNIT WILL SHUT OFF AS STATED ABOVE.

6.2. IF ON CALL FOR COOLING NO WATER FLOW IS DETECTED AS SENSED BY FLOW TRANSMITTER FT-2, AN ALARM WILL BE GENERATED AT THE BMS FRONT END AND

ABOVE SEQUENCE SHALL BE FOLLOWED.

7. AUTOMATIC SMOKE SHUTDOWN/RESTART:

7.1. IF SMOKE IS DETECTED BY ANY SMOKE DETECTOR SMD-1, OR 2, THE SUPPLY AND RETURN AIR FANS SHALL BE DEENERGIZED AND UNIT SHALL SHUT DOWN AS STATED

ABOVE.

7.2. THE UNIT SHALL BE STARTED MANUALLY.

8. EMERGENCY CONSTANT SPEED OPERATION:

8.1. UPON FAILURE OF ANY ONE VFD, FOR BOTH SUPPLY AND RETURN FAN ARRAYS, AN ALARM WILL BE GENERATED AND THE REMANING FANS WILL RAMP UP THEIR

SPEED TO MAINTAIN REQUIRED CFM.

9. HYDRONIC CONTROL:

9.1. THE HOT WATER SUPPLY AND RETURN TEMPERATURE FOR PREHEAT COIL SHALL BE MONITORED AT BMS FRONT END VIA TT-A AND TT-B. THE FLOW (GPM) SHALL BE

MONITORED VIA FT-1.

9.2. IF THE HOT WATER SUPPLY TEMPERATURE IS ABOVE 190 DEGREES F. (ADJ), AN ALARM SHALL BE GENERATED AT BMS FRONT END.

9.3. IF THE HOT WATER SUPPLY TEMPERATURE IS BELOW 150 DEGREES F, (ADJ), AN ALARM SHALL BE GENERATED AT BMS FRONT END.

9.4. THE CHILLED WATER SUPPLY AND RETURN TEMPERATURES FOR COOLING COIL SHALL BE MONITORED AT BMS FRONT END VIA TT-C AND TT-D. THE FLOW SHALL BE M

ONITORED VIA FT-2.

9.5. IF THE CHILLED WATER SUPPLY TEMPERATURE IS ABOVE 48 DEGREES F. (ADJ), AN ALARM SHALL BE GENERATED AT THE BMS FRONT END.

10. AIRFLITER MONITORING:

10.1. THE PRESSURE DROP ACROSS PREFILTER-1, 2 AND 3 AND FINAL FILTERS SHALL BE MONITORED AT THE CENTRAL BMS.

10.2. IF THE PRESSURE DROP EXCEED THE SETPOINT (TBD IN CONJUNCTION WITH VA), ALARM WILL BE GENERATED AT THE BMS FRONT END.

11. ENERGY MONITORING:
