The following table describes the attributes used by the Fan Supply Duct Static for UL-864-UUKL modules.

Table 1. Fan Supply Duct Static for UL-864-UUKL Attributes

Name

Type 1

Description

Default Value

Duct Static Pressure

 

Supply air duct static pressure.

250 Pa, 1 in. W.C.

Duct Static Pressure Setpoint

 

Normal supply air duct static pressure setpoint.

250 Pa, 1 in. W.C.

Emergency Duct Static Setpoint

 

Contains the supply air duct static pressure setpoint when Emergency S-P control is activated.

374 Pa, 1.5 in. W.C.

Emergency On Percent Cmd

 

Indicates the Percent Cmd issued during an emergency if the Duct Static Pressure is not reliable.

70%

FSCS SF Cmd

 

Accepts a command from the FSCS and allows emergency response personnel to control the supply fan. Possible states are Auto, Off, and On.

Auto

Set Name: Auto/Off/On

Mode

 

Desired mode of operation.

Off

Set Name: AHU SF Control

Output Overridden

 

Indicates when the actual output controlled by this output is overridden by a user.

False

Output Position

 

Provides the current Present Value of the output that this controller drives.

0%

PID Tuning Reset

 

Causes the PID objects to reset their tuning parameters to the default based on the appropriate Process ID.

Normal

Set Name: PID Tuning Reset

Priority

 

Specifies the BACnet priority for the output points. For normal control, this value is set to 16 (Default). This value is set to 1 when the FSCS input is not Auto and set to 2 (Automatic Fire/Life Safety Control) when the Mode indicates an emergency is not Normal.

16

Process Units

 

Specifies the units for the PID. For this particular module, Pa, in. W.C., Psi, and kPa are valid values.

Pa, in. W.C.

Set Name: Unit

Ramp Rate

 

Defines the rate of change in fan speed. This input is used in the Ramp mode.

50 Change per Minute

SF-OUTSTATE (State)

V, G

Indicates the current operational mode of the output controller.

Off

Set Name: AHU SF State

Supply Fan Control Status

V

PID Status. The possible values are Normal, Overridden, Disabled, Low, Timing Low, High, and Timing High.

Normal

Set Name: Control Status

Supply Fan OnOff

V

Contains the control signal for the supply fan. The enumeration set only has two values, Off and On.

Off

Set Name: Off/On

Supply Fan Percent Cmd

V

Analog signal for the supply fan and uses it to command a fan speed. This output ranges from 0% to 100%.

0.0%

1 C - Configuration Mode Only, G - Default Element (Generated State, if applicable), SC - Simulation and COmmissioning Modes Only, V - Calculated Value (Outputs)
