2. Specification Section 10 51 00 Lockers revised. See attachment.

3. Drawing M-701 Chilled water schematic – Revise flow meter to include analog input as indicated on points list.

4. Drawing M-701 Chilled water schematic – Revise CHILLED WATER FLOW METER upstream of chiller to read CHILLED WATER FLOW SWITCH and add chilled water flow switch and digital input to points list.

5. Drawing M-702 Heating water schematic – Revise flow meter point to analog input as indicated on points list.

6. Drawing M-703 DOAU Schematic – Remove wheel AI point.

7. Drawing M-703 Sequence of operation - Replace the ENERGY RECOVERY WHEEL section with the following:

ENERGY RECOVERY WHEEL: ENTHALPY WHEEL ROTATION SHALL BE CONTROLLED BASED ON DEW POINT

TEMPERATURE (CALCULATED BASED ON DRY BULB TEMPERATURE AND RELATIVE HUMIDITY).

HIGH OUTDOOR AIR HUMIDITY: IF THE OUTDOOR AIR INTAKE DEW POINT ENTERING THE ENERGY RECOVERY WHEEL IS GREATER THAN THE SUPPLY AIR WHEEL DISCHARGE DEW POINT SETPOINT OF 55°F (ADJ) (OUTSIDE AIR LEAVING THE ENERGY RECOVERY), AND GREATER THAN THE EXHAUST AIR DEW POINT ENTERING THE ENERGY RECOVERY WHEEL THEN THE ENERGY RECOVERY WHEEL SHALL ENERGIZE AND

MODULATE ROTATION SPEED TO MAINTAIN WHEEL DISCHARGE DEW POINT SETPOINT.

HIGH EXHAUST AIR HUMIDITY: IF THE OUTDOOR AIR INTAKE DEW POINT ENTERING THE ENERGY RECOVERY WHEEL IS GREATER THAN 55°F (ADJ) AND LESS THAN THE EXHAUST AIR ENTERING THE ENERGY

RECOVERY WHEEL DEW POINT THEN THE WHEEL SHALL BE OFF.

LOW OUTDOOR AIR HUMIDITY: IF THE OUTDOOR AIR INTAKE DEW POINT ENTERING THE ENERGY RECOVERY WHEEL IS LESS THAN 55°F (ADJ) THEN THE ENERGY RECOVERY WHEEL SHALL MODULATE ROTATION SPEED TO MAINTAIN A SUPPLY AIR TEMPERATURE SETPOINT OF 70°F (ADJ), BUT NOT EXCEED

WHEN THE SPACE CO2 LEVEL IS BELOW SETPOINT, THE VAV UNIT SHALL PROVIDE THE MINIMUM SETBACK OUTDOOR AIR FLOW RATE AS SCHEDULED IN THE VAV AND CAV TERMINAL BOX SCHEDULE. WHEN THE SPACE CO2 LEVEL RISES ABOVE SETPOINT, THE VAV UNIT SHALL MODULATE TO MAXIMUM OUTDOOR AIR FLOW

RATE AS SCHEDULED TO PROVIDE ADDITIONAL OUTSIDE AIR TO THE SPACE.

WHEN THE SPACE CO2 LEVELS ARE LESS THAN 600 PPM (ADJ) ABOVE MEASURED OUTSIDE AIR CO2 LEVELS, THE VAV UNIT SHALL MODULATE BACK TO MINIMUM SETBACK OUTDOOR AIR FLOW RATE.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

(A) HIGH CO2 LEVELS: IF SPACE CO2 LEVELS ARE GREATER THAN SPACE CO2 SETPOINT BY AN USER

DEFINABLE AMOUNT (ADJ).

9. Drawing M-703 Sequence of operation - Replace the 4th paragraph of SUPPLY AIR DUCT STATIC PRESSURE CONTROL section with the following:

THE EXHAUST FAN VFD SHALL ADJUST PROPORTIONATELY TO MAINTAIN 700 CFM (ADJ) DIFFERENTIAL BETWEEN SUPPLY AND EXHAUST AIRFLOW AS MEASURED BY SUPPLY AND EXHAUST AIRFLOW STATIONS.

EXHAUST VAV TERMINAL UNITS VAV-11 AND VAV-12 SHALL MODULATE PROPORTIONATELY TO

MAINTAIN CAV-5 AIRFLOW. IF CAV-5 IS FULLY OPEN AND UNABLE TO MAINTAIN AIRFLOW THAN VAV-11 AND VAV-12 SHALL INCREMENTALLY MODULATE CLOSED UNTIL CAV-5 ACHIEVES AIRFLOW AND IS 95

PERCENT OPEN.
