WHAT SYSTEMS WILL REMAIN OPERATIONAL THROUGHOUT CONSTRUCTION.

NOTIFY THE OWNER 24 HOURS MINIMUM PRIOR TO SHUTTING DOWN ANCILLARY

SYSTEMS OR EQUIPMENT.

4. REPAIR AND/OR REPLACE ALL EXISTING UTILITIES, STRUCTURAL ELEMENTS,

EQUIPMENT, PIPING, CONDUIT, DUCTWORK, ETC. THAT IS DAMAGED OR

BECOMES INOPERABLE AS A RESULT OF THIS WORK.

1. UNIT SHALL BE CONTROLLED DIRECTLY BY ITS OWN DEDICATED EMS DDC CONTROLLER.

2. THE EMS GLOBAL CONTROLLER SHALL DETERMINE WHEN TO ACTIVATE THEUNIT BASED

UPON BUILDING OCCUPANCY OR, OPTIONALLY, SCHEDULE.

3. A DUCT STATIC PRESSURE TRANSDUCER SHALL BE PROVIDED WITH THE SENSOR

LOCATED AT IN THE SUPPLY DUCT LENGTH. SUPPLY FAN SPEED SHALL BE VARIED AS

REQUIRED VIA VFD INTERFACE TO MAINTAIN DUCT STATIC PRESSURE SETPOINT

(ADJUSTABLE) AS SET BY SYSTEM OPERATOR AT OWS.

4. RETURN FAN SHALL OPERATE WHENEVER SUPPLY FAN IS IN OPERATION. RETURN FAN

SPEED SHALL BE VARIED AS REQUIRED VIA VFD INTERFACE TO MAINTAIN BUILDING

STATIC PRESSURE SETPOINT (ADJUSTABLE) AS SET BY SYSTEM OPERATOR AT OWS.

5. SUPPLY AIR TEMPERATURE SENSOR SHALL BE DIRECTLY CONNECTED TO UNIT DDC

CONTROLLER. THE SUPPLY AIR SETPOINT SHALL BE SET BY SYSTEM OPERATOR AT OWS

OR AUTOMATICALLY RESET, BY SYSTEM OPERATOR'S CHOICE, TO OPTIMALLY ADJUST

SUPPLY TEMPERATURE BASED ON ACTUAL BUILDING LOAD AS DETERMINED BY EMS

ZONE CONTROLLERS. SUPPLY AIR TEMPERATURE SETPOINT SHALL BE 65°F IF ALL “NEED

COOLING” SIGNALS ARE AT ZERO. SETPOINT SHALL BE 55°F IF WORST-CASE ZONE HAS A

“NEED COOLING” SIGNAL OF 100%. VARY THE SETPOINT BETWEEN 65°F AND 55°F AS ANY

ONE SIGNAL VARIES BETWEEN 0 AND 100%.

6. THE SYSTEM WILL SENSE OUTSIDE AIR, RETURN AIR AND MIXED AIR TEMPERATURES

AND SHALL MODULATE ECONOMIZER DAMPERS TO USE OUTSIDE AIR FOR COOLING

WHENEVER AVAILABLE. WHEN OUTSIDE AIR CAN NO LONGER BE USED FOR SUFFICIENT

COOLING, POSITION OUTSIDE AIR DAMPER TO MINIMUM POSITION. LOCK OUT HEATING

VALVE IN COOLING MODE.

7. WHEN HEATING IS REQUIRED, POSITION OUTSIDE AIR DAMPER TO MINIMUM POSITION

AND MODULATE HOT WATER VALVE TO MAINTAIN SUPPLY AIR TEMPERATURE SETPOINT.

8. PROVIDE A MORNING WARM-UP FEATURE TO MODULATE THE HOT WATER VALVE TO

MAINTAIN WARM-UP SUPPLY AIR TEMPERATURE SETPOINT UNTIL THE SPACE HAS

ACHIEVED SETPOINT.

9. PROVIDE FOR AUTOMATIC SHUTDOWN OF UNIT VIA HARDWIRE INTERLOCK UPON

DETECTION OF SMOKE IN THE MAIN SUPPLY AIR DUCT.

10.CO2 MONITORING: EMS CONTROLLER WILL BE CONNECTED TO WALL MOUNTED CO2

SENSORS TO MONITOR ZONE CO2 CONCNETRATION. DIRECT CONTROL OF OSA DAMPER

MINIMUM POSITION SHALL BE ACCOMPLISHED THROUGH EMS. THE MINIMUM OUTSIDE

AIR DAMPER POSITION WILL BE INCREASED TO PREVENT CO2 CONCENTRATION FROM

RISING ABOVE 800 PPM (ADJUSTABLE).

11.THE FOLLOWING COMMANDS/DISPLAYS SHALL BE AVAILABLE AT THE OWS FOR THE UNIT

SYSTEM:

a. SYSTEM GRAPHICS SHOWING DYNAMIC STATUS OF ALL POINTS.

b. AUTO/START/STOP.

c. BACNET VFD INTERFACE - SUPPLY & RETURN FANS.

d. OUTSIDE AIR (OSA) TEMPERATURE.

FAN COIL UNIT (FC-1) SYSTEM

1. Fan coil unit shall be controlled directly by its own dedicated EMS DDC

controller.

2. The EMS Global Controller shall determine when to activate the fan coil unit

based upon building occupancy or, optionally, an schedule.

3. Supply fan and return fan shall be commanded to run when fan coil unit is

activated. EMS shall monitor fan operation via EMS current transducer and

send alarm to OWS when fan fails to operate as commanded.

4. Supply air temperature sensor shall be directly connected to the fan coil unit

DDC controller. The supply air setpoint shall be set by system operator at

OWS or automatically reset, by system operator's choice, to optimally adjust

supply temperature based on actual space load as determined by EMS.

Supply air temperature setpoint shall be 65°F if “need cooling” signal is at

zero. Setpoint shall be 55°F if there is a “need cooling” signal.

5. The system will sense outside air, return air and mixed air temperatures and

shall modulate dampers to use outside air for cooling whenever available.

6. When outside air can no longer be used for sufficient cooling, position outside

air damper to minimum position. Lock out heating valve in cooling mode.

7. When heating is required, position outside air damper to minimum positionand

modulate hot water valve to maintain supply air temperature setpoint.

8. Provide a morning warm-up feature to modulate the hot water valve to

maintain warm-up supply air temperature setpoint until the space has

achieved setpoint.

9. Provide for automatic shutdown of fan coil unit via hardwire interlock upon

detection of smoke in the main supply air duct.

10. The following commands/displays shall be available at the OWS for the

AHU system:

a. System graphics showing dynamic status of all points.

b. Start/Stop.

c. Current fan status (current transducer).

d. Outside air (OSA) temperature.

e. Supply air temperature.

f. Return air temperature.

g. Mixed air temperature.
