SEQUENCE OF OPERATION

1. SUPPLY FAN START/STOP

1.1 THE SUPPLY FAN SHALL BE STARTED ACCORDING TO THE SCHEDULE. AFTER THE START COMMAND IS SENT, OUTSIDE AIR DAMPER, D-1, SHALL OPEN AND UNIT SHALL START WHEN DAMPER END SWITCH HAS PROVEN OPEN STATUS. IF THE SUPPLY FAN STATUS DOES NOT MATCH THE COMMANDED VALUE, AN ALARM SHALL BE GENERATED. WHEN THE SUPPLY FAN STATUS INDICATES THE FAN STARTED, THE

CONTROL SEQUENCE SHALL BE ENABLED.

2. SUPPLY AIR TEMPERATURE CONTROL

2.1 THE SUPPLY AIR SETPOINT SHALL RESET AS NECESSARY TO MAINTAIN THE ZONE TEMPERATURE SETPOINT AS SENSED BY THE ZONE TEMPERATURE SENSOR, T/H-1. THE PREHEAT FACE & BYPASS, PREHEAT VALVE, REHEAT VALVE, & COOLING VALVE SHALL MODULATE IN SEQUENCE TO MAINTAIN

THE SUPPLY AIR TEMPERATURE AT SETPOINT.

2.2 WHENEVER THE OUTSIDE AIR TEMPERATURE IS GREATER THAN 40°F, THE PREHEAT DISCHARGE SENSOR SHALL MODULATE THE STEAM PREHEAT VALVE TO MAINTAIN DISCHARGE AIR TEMPERATURE SETPOINT AND FACE AND BYPASS DAMPER SHALL BE OPEN TO COIL FACE. WHENEVER THE OUTSIDE AIR IS LESS THAN 40°F, PREHEAT COIL WILL OPEN AND FACE AND BYPASS DAMPERS MODULATE TO

MAINTAIN DISCHARGE AIR SETPOINT.

3. DEHUMIDIFICATION CONTROL

3.1 IF THE RETURN AIR DEWPOINT IN THE ZONE RISES ABOVE SETPOINT OF 55°F, THE CHILLED WATER VALVE, V-2, SHALL MODULATE OPEN TO MAINTAIN DEHUMIDIFICATION SETPOINT. THE REHEAT VALVE

SHALL MODULATE TO MAINTAIN SUPPLY AIR TEMPERATURE AT SETPOINT.

4. NIGHT SETBACK / NIGHT SETUP

4.1 IN UNOCCUPIED MODE, UNIT WILL CYCLE AS NECESSARY TO MAINTAIN THE NIGHT SETBACK ZONE TEMPERATURE AT SETPOINT. A DIFFERENTIAL PREVENTS THE UNIT FROM CYCLING EXCESSIVELY.

5. SAFETY

5.1 ALL SAFETY DEVICES SHALL HAVE STATUS ALARMS THAT ARE MONITORED AT THE ECC. ALL OF THE SAFETY DEVICES ARE MANUAL RESET. THE DEVICE THAT HAS TRIPPED MUST BE MANUALLY RESET

BEFORE RESTARTING THE AHU.

5.2 IF A TEMPERATURE LOW LIMIT SWITCH, T-1, SENSES A TEMPERATURE BELOW SETPOINT, THE SUPPLY

FAN SHALL BE SHUTDOWN.

5.3 IF A TEMPERATURE HIGH LIMIT SWITCH, T-2, SENSES A TEMPERATURE ABOVE SETPOINT, THE SUPPLY

FAN SHALL BE SHUTDOWN.

6. SHUTDOWN

6.1 WHEN THE UNIT IS SHUTDOWN BY EITHER A STOP COMMAND OR SYSTEM SAFETY, THE UNIT SHALL BE

SET AS FOLLOWS:

SUPPLY FAN SHALL BE OFF

OUTSIDE DAMPER, D-1, SHALL CLOSE

PREHEAT FACE & BYPASS REMAIN IN CONTROLS

SEQUENCE SHALL BE ENABLED.

2. SUPPLY AIR TEMPERATURE CONTROL

2.1 THE SUPPLY AIR SETPOINT SHALL RESET AS NECESSARY TO MAINTAIN THE ZONE TEMPERATURE SETPOINT AS SENSED BY THE ZONE TEMPERATURE SENSOR, T/H-1. THE PREHEAT FACE & BYPASS, PREHEAT VALVE, REHEAT VALVE, & COOLING VALVE SHALL MODULATE IN

SEQUENCE TO MAINTAIN THE SUPPLY AIR TEMPERATURE AT SETPOINT.

2.2 WHENEVER THE OUTSIDE AIR TEMPERATURE IS GREATER THAN 40°F, THE PREHEAT DISCHARGE SENSOR SHALL MODULATE THE STEAM PREHEAT VALVE TO MAINTAIN DISCHARGE AIR TEMPERATURE SETPOINT AND FACE AND BYPASS DAMPER SHALL BE OPEN TO COIL FACE. WHENEVER THE OUTSIDE AIR IS LESS THAN 40°F, PREHEAT COIL WILL OPEN AND FACE AND BYPASS DAMPERS MODULATE TO MAINTAIN DISCHARGE AIR

SETPOINT.

3. DEHUMIDIFICATION CONTROL

3.1 IF THE RETURN AIR DEWPOINT IN THE ZONE RISES ABOVE SETPOINT OF 55°F, THE CHILLED WATER VALVE, V-2, SHALL MODULATE OPEN TO MAINTAIN DEHUMIDIFICATION SETPOINT. THE REHEAT VALVE SHALL MODULATE TO MAINTAIN SUPPLY AIR TEMPERATURE AT SETPOINT.

4. ECONOMIZER CONTROL

4.1 ECONOMIZER IS ENABLED WHEN OUTSIDE AIR TEMPERATURE IS BELOW 65°F AND OA ENTHALPY IS BELOW RA ENTHALPY.

4.2 WHEN OA TEMPERATURE IS BETWEEN 65°F AND 55° RA DAMPER SHALL CLOSE AND OA DAMPER SHALL FULLY OPEN.

4.3 WHEN OA TEMPERATURE IS BELOW 55°F THE RETURN AIR DAMPER AND OUTSIDE AIR DAMPER SHALL MODULATE TO MAINTAIN THE MIXED AIR

TEMPERATURE SETPOINT.

5. NIGHT SETBACK / NIGHT SETUP

5.1 IN UNOCCUPIED MODE, UNIT WILL CYCLE AS NECESSARY TO MAINTAIN THE NIGHT SETBACK ZONE TEMPERATURE AT SETPOINT. A DIFFERENTIAL

PREVENTS THE UNIT FROM CYCLING EXCESSIVELY.

6. SAFETY

6.1 ALL SAFETY DEVICES SHALL HAVE STATUS ALARMS THAT ARE MONITORED AT THE ECC. ALL OF THE SAFETY DEVICES ARE MANUAL RESET. THE

DEVICE THAT HAS TRIPPED MUST BE MANUALLY RESET BEFORE RESTARTING THE AHU.
