UN-OCCUPIED MODE: • _ 1.THE EMCS SHALL DE-ENERGIZE THE UNIT SUPPLY AND ASSOCIATED EXHAUST AIR FAN,CLOSE THE OA AND EA DAMPERS,CLOSE THE CHW VALVE,ENERGIZE THE ELECTRIC HEATING COIL,OPEN THE RETURN AIR DAMPER. 2. IF SPACE TEMPERATURE DROPS BELOW UN-OCCUPIED WINTER SPACE TEMPERATURE SET-POINT OF 55°F(ADJUSTABLE)AS MEASURED BY THE SPACE TEMPERATURE SENSOR,THE EMCS SHALL ENERGIZE THE SUPPLY AIR FAN TO 60%FULL SPEED AND ENABLE ALL TEMPERATURE CONTROL ALGORITHMS TO PROVIDE HEATING UNTIL SPACE TEMPERATURE RISES TO 60°F(ADJUSTABLE}.THE OUTSIDE AIR AND EXHAUST AIR DAMPER SHALL REMAIN CLOSED AND THE RETURN AIR DRMPER SHALL REMAIN OPEN.SUPPLY FAN MUST BE ON TO ENABLE HEATING. 3. IF SPACE TEMPERATURE RISES ABOVE THE SUMMER UN-OCCUPIED TEMPERATURE SETPOINT OF 85°F(ADJUSTABLE)AS MEASURED BY THE SPACE TEMPERATURE SENSOR,THE EMCS SHALL ENERGIZE THE SUPPLY AIR FAN TO 60% FULL SPEED AND ENABLE ALL TEMPERATURE CONTROL ALGORITHMS TO PROVIDE COOLING UNTIL SPACE TEMPERATURE DROPS TO 80°F(ADJUSTABLE}.THE OUTSIDE AIR AND EXHAUST AIR DAMPER SHALL REMAIN CLOSED AND THE RETURN AIR DAMPER SHALL REMA{N OPEN.SUPPLY FAN MUST BE ON TO ENABLE COOLING. OCCUPIED MODE WHEN OUTSIDE AIR TEMPERATURE IS 62°F AND ABOVE: 1. BLOWER COIL FAN CONTROL: 1.1. THE EMCS SHALL MODULATE THE VFD FREQUENCY BASED ON A SIGNAL FROM THE SPACE TEMPERATURE SENSOR TO MAINTAIN THE SPACE TEMPERATURE AT 75°F. 12. HEATING THE EMCS SHALL MODULATE THE VFD FREQUENCY BASED ON A SIGNAL FROM THE SPACE TEMPERATURE SENSOR TO MAINTAIN THE SPACE TEMPERATURE AT 70°F. 2. EXHAUST FAN CONTROL: 2.1_ THE EXHAUST FAN SHALL BE MODULATED TO TRACK THE OUTSIDE AIRFLOW WITH AND OFFSET TO MAKE THE SPACE NEGATIVE BY 200 CFM. 3. DAMPER CONTROL: 3.1. RETURN AIR DAMPER SHALL BE FULLY OPEN UNLESS NEEDED TO MAINTAIN OA AIRFLOW SETPOINT.OA DAMPER SHALL BE MODULATED TO MAINTAIN MINIMUM OA AIRF�OW SETPOINT-720 CFM. 4. COIL CONTROL: 4.1. COOLING THE EMCS SHALL MODULATE THE CHILLED WATER CONTROL VALVE TO MAINTAIN THE COOLING COIL LEAVING AIR TEMPERATURE(CCLAT)SETPOINT OF 54°F. , 5. BOOSTER SUPPLY FAN CONTROL: 5.1. THE EMCS SHALL MODULATE THE VFD FREQUENCY BASED ON DUCT STATIC TO MAINTAIN STATIC PRESSURE SETPOINT(ADJUSTABLE)W THE OUTSIDE AIR DUCT. - RUN MODE WHEN OUTSIDE AIR TEMPERATURE IS BELOW 62°F(ECONOMIZER MODE): 1. BLOWER COIL SUPPLY FAN CONTROL: 1.1. COOLING THE EMCS SHALL MODU�ATE THE VFD FREQUENCY BASED ON A SIGNAL FROM THE SPACE TEMPERATURE SENSOR TO MAINTAIN THE SPACE TEMPERATURE AT 75°F. 2. EXHAUST FAN CONTROL: 2.1. THE EXHAUST FAN SHALL BE MODULRTED TO MAINTAIN MAINTAIN THE GREATER OF: 2.1.1. 200 CFM MORE THAN THE OA CFM. 2.1.2. 2000 CFM. 3. DAMPER CONTROL: 3.1. ECONOMIZER MODE SHALL BE DISABLE0. THE EMCS SHALL MODU�ATE THE OA AND RA DAMPERS TO MAINTAIN THE SA TEMPERATURE OF 55°F.THE OA AIRFtOW SHALL NOT BE ALLOWED TO FAL�BELOW THE SCHEDULED MINIMUM OA AIRFLOW. IF THE MIXED AIR TEMPERATURE FALLS BELOW 38°F OR THE�OW TEMP SENSOR GOES INTO ALARM, 4. COIL CONTROL: 4.1. COOLWG:THE EMCS SHA��MODULATE THE CHW CONTROL VALVE TO MAINTAIN THE SA TEMPERATURE SETPOINT OF 55° F. 4.2.
