SEQUENCE OF OPERATIONS

EXHAUST FAN (EF-X)

GENERAL DESCRIPTION

The exhaust fans provide exhaust ventilation to the conditioned space(s) as shown on the drawings.

OPERATING MODES

NORMAL OPERATING MODE

The exhaust fan shall be in occupied mode per the project design conditions schedule shown on sheet M-701.

BACKUP MODE

Backup mode shall be activated upon failure of the lead exhaust fan. Backup mode shall be disabled by manual reset.

UNOCCUPIED MODE

The exhaust fan shall be in unoccupied mode for all periods not included in the occupied hours of operation.

SAFETIES, OVERRIDES, AND INTERLOCKS

The exhaust fan shall be disabled via hard wired interlock at the fan start circuit upon activation of the EA duct static pressure controller.

COMPONENT CONTROL LOOPS

EXHAUST FAN 1 – ON/OFF

• When the HOA switch is in hand position, the variable speed supply fan shall operate at a speed set manually by the operator at the user interface of the drive.

• When the HOA switch is in off position, the fan shall be off.

• When the HOA switch is in auto position, the variable speed supply fan shall operate subject to the unit enable signal, and unit operating modes.

NORMAL OPERATING MODE:

The controller shall measure the EA static pressure and modulate the exhaust fan to maintain the EA static pressure setpoint. The minimum fan speed shall be determined during testing and balancing.

BACKUP MODE:

The exhaust fan shall be off.

UNOCCUPIED MODE:

The exhaust fan shall be off.

EXHAUST FAN 2 – ON/OFF

• When the HOA switch is in hand position, the variable speed supply fan shall operate at a speed set manually by the operator at the user interface of the drive.

• When the HOA switch is in off position, the fan shall be off.

• When the HOA switch is in auto position, the variable speed supply fan shall operate subject to the unit enable signal, and unit operating modes.

NORMAL OPERATING MODE:

The exhaust fan shall be off.

BACKUP MODE:

Upon failure of the lead exhaust fan, the backup exhaust fan shall be activated and shall operate as the lead exhaust fan until manually reset to normal operating mode.

UNOCCUPIED MODE:

The exhaust fan shall be off.

MOTORIZED DAMPER 1

NORMAL OPERATING MODE:

The motorized damper shall be open. The motorized damper shall open 30 sec (adj.)

prior to activation of the exhaust fan.

BACKUP MODE:

The motorized damper shall operate as if in unoccupied mode.

UNOCCUPIED MODE:

The motorized damper shall be closed. The motorized damper shall close 30 sec (adj.) after the fan is OFF.

MOTORIZED DAMPER 2

NORMAL OPERATING MODE:

The motorized damper shall operate as if in unoccupied mode.

BACKUP MODE:

The motorized damper shall operate as the lead motorized damper until manually reset to normal operating mode.

UNOCCUPIED MODE:

The motorized damper shall be closed. The motorized damper shall close 30 sec (adj.) after the fan is OFF.
