from its minimum setting to a maximum of 50%(adjustable by user at the BMS).




D. Coast down Mode - When the unit is turned "OFF" by the BAS for optimal stop, the supply

fan remains "ON", the outside air damper remains open for ventilation, and a setpoint offset is

initiated to limit heating and cooling. Space comfort is protected by the user defined setpoint

offset.

E. Duty Cycle Mode - When the unit is duty cycled "OFF" it is put in a user-defined Duty Cycle

Mode. User defines max/min temperature limits to ensure occupant comfort and override

duty cycle if limits are exceeded.

F. Demand Limit Mode - Through the BAS a user defined Demand Limit Mode shall be

available. User defines maximum off time and temperature to ensure occupant comfort.

G. Night Setback Temperature Control - When the BAS selects unoccupied mode, the unit shall

be controlled to maintain user defined unoccupied heating and cooling setpoints. The outdoor

air damper remains closed during heating night setback operation, if provided.

H. Nighttime Free-Cool Purge Mode - An "economizer only" cooling cycle shall be provided

during unoccupied hours when outdoor air conditions are suitable and the zone requires

cooling.

I. Low Ambient Compressor Lockout - Compressor operation shall be disabled below a user

defined outdoor air temperature.

J. Timed Override - When a timed override is initiated by the user, the unit will return to its user

defined normal occupied mode for the user determined period of time.

e. Flow Alarm LED, which illuminates to indicate an unsafe airflow condition. The

audible alarm will also activate and may be muted.

f. Broken retracting cable alarm, an audible alarm with a flashing LED that indicates

whether a vertical sash sensor cable is detached, thereby ensuring the fume hood

users’ safety.

g. Energy waste alarm option, which generates a local visual and audible alarm to notify

when the fume hood sash is open beyond its minimum flow position and the lights in

the room are off. When activated, the LED display will show “ENRG” and the

audible alarm will sound until the sash is closed. The light levels at which the alarm

is both initiated and cancelled shall be configurable.

h. Fume hood decommissioning option, which commands the exhaust flow through the

fume hood to the minimum allowed by the exhaust valve when the sash is fully

closed and no chemicals are present in the hood. The mode shall be initiated by either

a pushbutton sequence on the fume hood monitor, external momentary switch input

to the fume hood monitor, or a network command. When activated, the LED display

will show “OFF,” and the exhaust valve will move to its minimum position or shutoff

position. Safety shall be built into the decommission option, whereby opening the




fume hood sash will automatically return the fume hood exhaust to an in-use

operating volume as determined by the sash sensor.

E. Fume Hood Monitor (Two-Position – Fume Hoods located in Prep Room C130A & AP

Chemistry, E2)
