AIR HANDLING EQUIPMENT

VARIABLE AIR VOLUME AIR HANDLING UNIT (AHU-09)

1. OCCUPIED MODE

A. THE AHU WILL START ON COMMAND FROM THE BAS, WHEN THE HOA SWITCH IS IN THE "AUTO" MODE. THE AHU MAY ALSO BE STARTED LOCALLY WHEN THE HOA

SWITCH IS PLACED IN THE "HAND MODE".

B. WHEN THE AIR HANDLER IS COMMANDED TO START THE OUTDOOR AIR DAMPER SHALL BE OPENED 100% AND PROVE "OPEN" BASED ON INPUT FROM THE DAMPER END SWITCH, PRIOR TO STARTING THE SUPPLY AND RETURN FANS. IF THE OUTDOOR AIR DAMPERS DO NOT PROVE OPEN THE FAN SHALL REMAIN OFF AND AN ALARM SHALL BE ROUTED TO THE OPERATOR'S WORKSTATION. ONCE THE OUTDOOR AIR DAMPER IS VERIFIED OPEN, THE DAMPER SHALL MODULATE TO MINIMUM

POSITION.

C. WITH THE OUTDOOR DAMPER VERIFIED OPEN THE VFD SHALL START AND MODULATE THE SUPPLY AND RETURN FANS. CURRENT TRANSFORMER (CT) SWITCHES SHALL SIGNAL THE CONTROLLER TO VERIFY OPERATION OF THE SUPPLY AND RETURN FANS. IF SUPPLY FAN OPERATION IS NOT VERIFIED WITHIN 30 SECONDS (CUSTOMER ADJUSTABLE) THEN THE UNIT SHALL BE SHUT DOWN AND AN ALARM BE ROUTED TO THE OPERATORS WORKSTATION. IF THE RETURN FAN OPERATION IS NOT VERIFIED THE UNIT SHALL CONTINUE TO OPERATE AND AN ALARM SHALL BE ROUTED TO THE OPERATORS WORKSTATION.

D. THE AHU SHALL STOP WHEN COMMANDED BY THE BAS, OR WHEN THE HOA SWITCH IS PLACED IN "HAND". THE UNIT SHALL SHUT DOWN BY FIRST COMMANDING OFF THE FAN VFDS, WHEN THE FANS ARE PROVEN OFF (BY THE CT INPUT) THE OUTDOOR AIR DAMPER SHALL THEN BE CLOSED.

2. UNOCCUPIED MODE

A. WHEN IN UNOCCUPIED MODE, THE UNIT SHALL BE DE-ENERGIZED (FANS OFF, OUTSIDE AIR DAMPER CLOSED).

B. IN UNOCCUPIED MODE, WHEN A MINIMUM OF TWO (2) (ADJ.) VAV TERMINAL UNITS CALL FOR HEATING OR COOLING, THE AIR HANDLING UNIT SHALL BE ENERGIZED.

THE UNIT SHALL OPERATE NORMALLY IN EITHER HEATING OR COOLING MODE, BUT THE OUTSIDE AIR DAMPER SHALL BE CLOSED. ECONOMIZER SHALL BE DISABLED

DURING UNOCCUPIED MODE.

3. THE AHU WILL STOP (FANS OFF, ALL DAMPERS CLOSED) AND AN ALARM BE ROUTED TO THE OPERATORS WORKSTATION WHEN ANY OF THE FOLLOWING CONDITIONS

OCCUR:

A. IF EMERGENCY STOP SWITCH IS IN "PUSHED" POSITION, THEN THE SWITCH MUST BE MANUALLY "PULLED" IN ORDER TO RESTART THE AHU.

B. IF HIGH DISCHARGE PRESSURE SWITCH LOCATED IN THE UNIT AND AFTER THE SUPPLY FAN IS TRIGGER DUE TO HIGH PRESSURE, THE AHU SHALL SHUT DOWN AND

WILL NOT RESTART AUTOMATICALLY. (HIGH STATIC PRESSURE SWITCH SHALL BE SET ACCORDING TO TEST AND BALANCE'S INSTRUCTION.)

C. IF THE VAPOR TENSION LOW LIMIT THERMOSTAT ("FREEZESTAT") SENSE A TEMPERATURE BELOW 35 DEGREES (SHALL REQUIRE A MANUAL RESET.)

D. IF RETURN DUCT HIGH TEMPERATURE ("FIRESTAT") IS TRIGGERED, THE AHU SHALL SHUT DOWN AND WILL NOT RESTART. (SET AT 125 DEGREES, F.)

E. SMOKE MODE - IF ANY OF THE DUCT MOUNTED SMOKE DETECTORS (FURNISHED AND INSTALLED BY DIVISION 28) AND INSTALLED IN THE SUPPLY AIR STREAM

DETECT SMOKE OR A SPACE DETECTOR DETECTS SMOKE THE SUPPLY AIR FANS AND RETURN AIR FANS SHALL SHUT DOWN AND ALL DAMPERS SHALL CLOSE.

4. DISCHARGE CONTROL

A. THE PRE-HEAT COIL AIR TEMPERATURE SENSOR IS LOCATED DIRECTLY DOWNSTREAM OF THE PRE-HEAT COIL. CONTROL THE PRE-HEAT COIL DISCHARGE TEMPERATURE TO 50 DEGREES F (ADJUSTABLE) BY MODULATING THE PRE-HEAT COIL CONTROL VALVE.

B. THE COOLING COIL AIR TEMPERATURE SENSOR IS LOCATED DIRECTLY DOWNSTREAM OF THE COOLING COIL. CONTROL THE COOLING COIL DISCHARGE TEMPERATURE TO 60 DEGREES F (ADJUSTABLE) BY MODULATING THE COOLING COIL CONTROL VALVE.

C. THE PRE-HEAT VALVE WILL FAIL SAFE TO THE NORMAL OPEN POSITION. WHEN THE OA TEMPERATURE FALLS BELOW 45 DEGREES (SET POINT ADJUSTABLE), THE PRE-HEAT VALVE SHALL MODULATE TO MAINTAIN DOWNSTREAM AIR TEMPERATURE SET POINT. WHEN THE OUTSIDE AIR TEMPERATURE IS ABOVE 50 DEGREES (SET

POINT ADJUSTABLE), THE PRE-HEAT CONTROL VALVE SHALL CLOSE.

D. AHU COILING COILS SHALL UTILIZE A STANDARD CONTROL VALVE ARRANGEMENT AND SHALL BE CONTROLLED AS FOLLOWS:

a. ON AN INCREASE IN COOLING LOAD, THE CONTROL VALVE SHALL MODULATE OPEN TO MAINTAIN THE DISCHARGE AIR TEMPERATURE SET POINT. UPON A

DECREASE IN COOLING LOAD, THE CONTROL SHALL MODULATE CLOSED TO MAINTAIN THE DISCHARGE AIR TEMPERATURE SET POINT.

5. SUPPLY FAN CONTROL

A. MODULATE ALL VFD'S AT THE SAME SPEED TO MAINTAIN THE SUPPLY AIR DUCT STATIC PRESSURE SENSOR WITH THE LOWEST READING AT SET POINT. A STATIC

PRESSURE TRANSMITTER SHALL BE LOCATED 2/3 DOWN THE LONGEST DUCT.

B. IF THE STATIC PRESSURE SENSOR BECOMES UNRELIABLE, THE CONTROLLER WILL COMMAND THE SUPPLY FAN VFD TO ITS MINIMUM SPEED AND AN ALARM SHALL

BE ROUTED TO THE OPERATOR'S WORKSTATION.

C. RESET THE DUCT STATIC PRESSURE SENSOR TO KEEP AT LEAST ONE VAV BOX SUPPLY AIR DAMPER AT 95% OPEN.

6. RETURN FAN TRACKING

A. THE RETURN FAN AIRFLOW SHALL TRACK THE SUPPLY AIRFLOW UTILIZING AN OFFSET VALUE AS MEASURED WITH THE AIRFLOW MONITORS IN THE UNIT. THE OFFSET SHALL BE ESTABLISHED AT FINAL TEST AND BALANCE TO KEEP THE BUILDING AT SLIGHTLY POSITIVE PRESSURE.

7. ECONOMIZER MODE

A. OUTSIDE AIR TEMPERATURE SHALL BE COMPARED WITH A REFERENCE DRY BULB SETPOINT (OWNER ADJUSTABLE). ECONOMIZER MODE SHALL BE ENABLED WHEN

THE OUTSIDE AIR TEMPERATURE IS LESS THAN THE REFERENCE DRY BULB SETPOINT. ECONOMIZER MODE SHALL BE DISABLED WHEN THE OUTSIDE AIR

TEMPERATURE IS GREATER THAN THE REFERENCE DRY BULB SETPOINT.

B. THE DISCHARGE AIR SENSOR SHALL MEASURE THE DRY BULB TEMPERATURE OF THE AIR LEAVING THE COOLING COIL WHEN ECONOMIZER MODE IS ENABLED. THE OUTSIDE AIR DAMPER SHALL MODULATE BETWEEN IT'S MINIMUM POSITION AND 100% TO MAINTAIN DISCHARGE AIR TEMPERATURE AT SETPOINT.

C. OUTSIDE AIR DAMPER SHALL MODULATE TO MINIMUM POSITION IN EVENT MIXED AIR TEMPERATURE FALLS BELOW LOW LIMIT TEMPERATURE SETTING AND

ECONOMIZER MODE SHALL BE DISABLED.

D. WHEN THE ECONOMIZER MODE IS DISABLED THE OUTDOOR AIR DAMPER SHALL BE SET TO MINIMUM POSITION REQUIRED BY VENTILATION.

VAV TERMINALS

1. ALL VAVS SHALL OPERATE ON A 7-DAY OCCUPIED/UNOCCUPIED SCHEDULE. INITIAL OCCUPIED SCHEDULE SHALL BE MONDAY – FRIDAY FROM 8:00AM TO 5:00PM AND SHALL

BE FULLY ADJUSTABLE VIA THE BAS.

2. SPACE TEMPERATURE SETPOINTS IN EACH MODE SHALL BE AS FOLLOWS AND SHALL BE FULLY ADJUSTABLE VIA THE BAS:

COOLING HEATING

OCCUPIED MODE 72 DEF F 68 DEG F

UNOCCUPIED MODE 78 DEF F 62 DEG F

3. PROVIDE PRESSURE INDEPENDENT CONTROL (I.E., THE SUPPLY AIR CFM SET POINT IS RESET TO MAINTAIN THE SPACE TEMPERATURE COOLING SET POINT.)

4. OCCUPIED / UNOCCUPIED MODE - INDEX BASED ON THE ASSOCIATED ZONE'S TIME SCHEDULE (OR THAT FOR THE AHU IF ALL BOXES SERVED THE BY THE AHU HAVE THE

SAME SCHEDULE) OR BY THE ASSOCIATED OCCUPANCY SENSOR. THE SUPPLY AIR DAMPER AND REHEAT COIL VALVE SHALL BE CLOSED IF THE ASSOCIATED AHU IS OFF.

5. HEATING - MODULATE THE HEATING COIL TO MAINTAIN THE OCCUPIED OR UNOCCUPIED SPACE HEATING SET POINT WHILE MAINTAINING THE BOX SUPPLY AIR CFM AT THE

MINIMUM SETTING FOR THE HEATING MODE (WHICH MAY BE A DIFFERENT VALUE THAN THAT FOR COOLING IF PROVIDED).

6. COOLING OPERATION - DO NOT RESET THE SUPPLY AIR CFM BELOW THE MINIMUM SUPPLY AIR SET POINT OR ABOVE THE MAXIMUM.

7. DEADBAND - PROVIDE A DEADBAND BETWEEN THE HEATING AND COOLING SPACE TEMPERATURE SET POINTS IN WHICH THE MINIMUM SUPPLY AIR CFM IS DELIVERED AND

NO HEATING IS PROVIDED.

8. MINIMUM SUPPLY AIR SET POINT (WHEN COOLING OR IN THE DEADBAND) - THE SET POINT SHALL BE THAT NEEDED FOR VENTILATION WHILE OPERATING IN THE OCCUPIED

MODE ONLY; OTHERWISE THE MINIMUM SHALL BE "ZERO" (I.E., DURING AHU UNOCCUPIED HEATING / COOLING, OR AHU WARM-UP OR COOL-DOWN DUE TO OPTIMUM START.)

HYDRONIC UNIT HEATER

1. ELECTRIC UNIT HEATERS EUH-1 SHALL BE CONTROLLED BY LINE-VOLTAGE THERMOSTATS INTEGRAL TO THE UNITS. THERMOSTATS SHALL BE PROVIDED BY THE UNIT MANUFACTURER. TEMPERATURE SETPOINT SHALL BE SET AT 60 DEG F AND SHALL BE ADJUSTABLE AT THE UNIT.

2. A SPACE TEMPERATURE SENSOR SHALL BE LOCATED IN THE MECHANICAL ROOM AT THE LOCATION SHOWN ON THE FLOOR PLAN. SENSOR SHALL REPORT BACK TO THE BUILDING AUTOMATION SYSTEM. A LOW SPACE TEMPERATURE ALARM SHALL BE DISPLAYED ON THE BAS WHEN THE SPACE TEMPERATURE DROPS BELOW 55 DEG F (ADJ.).
