1.17.5.2. When the full fresh air override is activated by an operator, the affected AHU shall immediately transition to full fresh air mode, opening the fresh air damper to 100%, opening the exhaust damper to 100%, driving the return air damper to fully closed, and commanding the extract fans associated with that AHU to full operation, regardless of the current automatic control mode or schedule

1.17.5.3. When the full fresh air override is active, the cooling coil valve and heating coil valve shall be commanded to their respective off or closed positions unless safety conditions require otherwise

1.17.5.4. When the full fresh air override is activated, a clearly visible notification shall appear on the BAS graphics alarm and notification area on the Niagara N4 Supervisor and on all three operator interface touchscreens.

1.17.6. Full Fresh Air / Free Cooling Sequence: The Contractor shall implement a full fresh air/free cooling sequence for each AHU. This sequence shall operate as follows:

1.17.6.1. During occupied hours, when outside air conditions (temperature and humidity) meet predefined parameters set by the Building Engineer, the system shall modulate toward full fresh air cooling, reducing or eliminating mechanical cooling demand while maintaining the minimum supply air temperature limit.

1.17.6.2. After hours, the system shall automatically operate in full fresh air/free cooling mode to cool the building down overnight. During after hours free cooling operation, the minimum supply air temperature limit shall be overridden to allow the system to take full advantage of cooler outside air conditions without restriction from the supply air temperature low limit. The fresh air damper shall open to 100%, the return air damper shall be driven to fully closed, the exhaust damper shall open to 100%, and mechanical cooling shall be disabled.

1.17.6.3. The after hours free cooling mode shall operate according to a configurable schedule set by the Building Engineer and shall automatically return the AHU to normal occupied control at the configured occupied start time.

1.17.6.4. All free cooling mode transitions shall be logged in the BAS event database with timestamps.

1.17.7. Cooling Control: The Contractor shall implement the following cooling control strategy for each AHU:

1.17.7.1. The primary cooling control variable shall be the return air temperature. The chilled water cooling coil valve shall be modulated to maintain the return air temperature at a user settable return air temperature setpoint.

1.17.7.2. In addition to return air temperature control, a settable maximum supply air temperature limit and a settable minimum supply air temperature limit shall be implemented for each AHU. These limits shall act as high and low supply air temperature constraints on the cooling control output during occupied hours. The minimum supply air temperature limit shall be overridden during after hours free cooling operation as described in Section 5.4.7.2.

1.17.7.3. If the supply air temperature rises above the settable maximum supply air temperature limit, the cooling control output shall be increased to bring the supply air temperature back within the acceptable range, regardless of the return air temperature control demand.

1.17.7.4. If the supply air temperature falls below the settable minimum supply air temperature limit during occupied hours, the cooling control output shall be reduced or the cooling coil valve shall be commanded toward closed to prevent over cooling of the supply air, regardless of the return air temperature control demand.

1.17.7.5. All cooling control setpoints, including the return air temperature setpoint, the maximum supply air temperature limit, and the minimum supply air temperature limit, shall be adjustable by authorized operators from the Niagara N4 Supervisor, the Building Engineer's office touchscreen, AHU plantroom and the chiller plant area touchscreen.

1.17.7.6. The current return air temperature, supply air temperature, cooling coil valve position, and all active cooling setpoints shall be displayed on the AHU graphic pages on the Niagara N4 Supervisor and on both operator interface touchscreens.

1.17.7.7. An alarm shall be generated if the supply air temperature exceeds the maximum supply air temperature limit or falls below the minimum supply air temperature limit during occupied hours for a configurable time period, indicating that the cooling system is unable to maintain the supply air temperature within the required range.
