3. ZONE SETPOINT ADJUST: THE OCCUPANT SHALL BE ABLE TO ADJUST THE ZONE

TEMPERATURE HEATING AND COOLING SETPOINTS AT THE ZONE SENSOR BY ±2°F.

4. TEMPERATURE CONTROL DEVICES SHALL BE EQUIPPED WITH DEADBANDS THAT

COMPLY WITH IECC 2015.

1. THE CONTRACTOR MUST FIELD VERIFY THE EXISTING DDC SYSTEM TO DETERMINE

CONDUIT ROUTING AND CONTROL HARDWARE REQUIRED (INCLUDING BUT NOT

LIMITED TO, CABINETS, EXPANSION MODULES, CONTROLLERS, RELAYS, CONTACTORS,

ETC.) TO INTEGRATE NEW HVAC EQUIPMENT AND LIGHTING CIRCUITS PRIOR TO BID.

REFER TO TECHNICAL SPECIFICATION SECTION 23 09 23 FOR ADDITIONAL

INFORMATION.

2. COORDINATE WITH OTHER UTILITIES TO AVOID INTERFERENCES WHEN INSTALLING

SENSORS, CONTROLLERS, CONDUIT, AND CABLE.

3. FURNISH AND INSTALL ALL SENSORS, CONTROLLERS, CONDUIT, AND CABLE AS PER

MANUFACTURER'S RECOMMENDATIONS AND INSTRUCTIONS.

4. PROVIDE FIRE CAULKING AT ALL FIRE BARRIER CONDUIT PENETRATIONS.

5. CONDUIT HANGERS AND SUPPORTS - ALL HANGERS AND SUPPORTS SHALL COMPLY

WITH MANUFACTURER'S STANDARDIZATION SOCIETY (MSS) STANDARDS. VERTICAL

CONDUITS MUST BE SUPPORTED AT EACH FLOOR WITH CLAMPS.

6. THE ONBOARD BACNET CONTROLLERS SHALL COMMUNICATE WITH THE BAS TO

ALLOW, AT A MINIMUM, MONITORING AND CONTROL OF I/O POINTS LISTED. THE

SYSTEM SHALL BE ENABLED BY THE BAS. ALL CONTROL POINTS ON THE I/O POINTS LISTS

SHALL BE MONITORED AND CONTROLLED FROM THE GUI. CONTROLLER SHALL HAVE

UNIMPEDED TWO-WAY COMMUNICATION WITH ALL DEVICES. REFER TO TECHNICAL

SPECIFICATION SECTION 23 09 23 FOR ADDITIONAL INFORMATION.

7. ALARMS: THE ONBOARD BACNET CONTROLLERS SHALL TRANSMIT SYSTEM ALARMS TO

THE GRAPHIC USER INTERFACE (GUI). THE ONBOARD CONTROLLERS SHALL, AT A

MINIMUM, TRACK ALARMS LISTED IN THE I.O POINTS LIST. REFER TO TECHNICAL

SPECIFICATION SECTION 23 09 23 FOR ADDITIONAL INFORMATION.

1. DOAS:

1.1 THE DOAS SHALL BE A PACKAGED UNIT WITH A SUPPLY FAN AND EXHAUST FAN.

1.2 THE DOAS SHALL BE PROVIDED WITH A VFD FOR THE SUPPLY FAN, AND A VFD FOR THE EXHAUST FAN.

1.3 THE DOAS SHALL BE CONTROLLED BY THE BAS AND REMAIN ENABLED AT ALL TIMES.

1.3.1 DURING OCCUPIED HOURS, THE DOAS SHALL RUN CONTINUOUSLY AND DELIVER A CONSTANT AIR VOLUME CALCULATED PER ASHRAE 62.1.

1.3.2 DURING UNOCCUPIED HOURS, THE DOAS SHALL NOT RUN UNLESS A ZONE OVERRIDE COMMAND IS RECEIVED.

1.3.3 OCCUPIED/UNOCCUPIED HOURS SHALL BE DETERMINED BY BUILDING SCHEDULE IN THE BAS.

2. DOAS CONTROL: THE DOAS SYSTEM SHALL BE PROVIDED WITH A FACTORY FURNISHED ON-BOARD BACNET CONTROLLER THE MANUFACTURER SHALL USE ITS PREFERRED SEQUENCE TO MEET THE FOLLOWING

REQUIREMENTS:

2.1 IN COOLING, THE CONTROLLER SHALL MONITOR THE CHILLED WATER COIL LEAVING AIR TEMPERATURE AND MODULATE CHILLED WATER FLOW TO MAINTAIN THE CHILLED WATER COIL LEAVING AIR

TEMPERATURE SET POINT OF 55°F.

2.2 IN HEATING, THE CONTROLLER SHALL MONITOR THE SUPPLY AIR TEMPERATURE AND MODULATE THE HOT WATER COIL TO MAINTAIN THE SUPPLY AIR TEMPERATURE SETPOINT OF 70°F.

2.3 IN ECONOMIZER, THE UNIT SHALL RUN USING AN OUTSIDE AIR DRY-BULB BASED CONTROL STRATEGY.

3. FAN CONTROL:

3.1 SUPPLY AIR FAN: THE CONTROLLER SHALL MONITOR DUCT STATIC PRESSURE AND MODULATE SUPPLY AIR FLOW THROUGH THE VFD TO MAINTAIN DOWNSTREAM STATIC PRESSURE SET POINT. SENSOR

LOCATION AND SETPOINT SHALL BE DETERMINED BY THE TAB FIRM.

3.2 EXHAUST AIR FAN: EXHAUST AIR SHALL MODULATE TO BE 200 CFM LESS THAN SUPPLY AIR TO MAINTAIN A POSITIVE STATIC PRESSURE FOR THE SPACE.

4. CONTROLLER:

4.1 THE ONBOARD BACNET CONTROLLER SHALL COMMUNICATE WITH THE BAS TO ALLOW AT THE MINIMUM MONITORING AND CONTROL OF I/O POINTS LISTED HERE. THE SYSTEM SHALL BE ENABLED BY THE

BAS. ALL CONTROL POINTS ON THE I/O POINTS LIST SHALL BE MONITORED AND CONTROLLED FROM THE GRAPHIC USER INTERFACE (GUI).

5. ALARMS:

5.1 THE ONBOARD BACNET CONTROLLER SHALL TRANSMIT SYSTEM ALARMS TO THE GUI. THE ONBOARD CONTROLLER SHALL, AT A MINIMUM, TRACK ALARMS LISTED IN THE I/O POINTS LIST.
