The following table describes the attributes used by the Cooling FBPD 2 Position Valve with Dehumidification modules:

Table 1. Cooling FBPD 2 Position Valve with Dehumidification Attributes

Name

Type 1

Description

Default Value

CLG-OUTSTATE (State)

V, G

Indicates the current operational mode of the output controller.

Off

Set Name: AHU Clg FBPD Out

Cooling Control Status

V

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

Normal

Set Name: Control Status

Damper Percent Cmd

V

Controls the face and bypass damper. The damper is commanded from 0% (full bypass) to 100% (full face).

0%

Dehum Process ID

 

Specifies the type of process that this output controller is controlling when the mode is H Control.

RA-H

Set Name: Process ID

Failsoft Value

 

Defines the face and bypass damper position when the module is in the Failsoft state.

100%

Humidity Process Variable

 

Value of the humidity being measured by the humidity sensor. It is used as the process variable in the dehumidification control.

50% RH

Humidity Setpoint

 

Dehumidification Setpoint.

50% RH

Limited Max Value

 

Defines the face and bypass damper position when the module is in the Limited Max Heating state.

100%

Low OA Temperature Diff

 

Contains the differential for the Low OA Temperature mode. Once the valve has been in the Low AO Temperature mode, the OA Temperature must increase Low OA Temperature Diff more than the Low OA Temperature Setpoint before the valve can close.

0.5 °C, 1 °F

Low OA Temperature Setpoint

 

Setpoint for the Low OA Temperature mode. When the OA Temperature is below this setpoint, the valve opens and the face and bypass dampers are be set to 100%.

4 °C, 40 °F

Mode

 

Desired mode of operation.

Off

Set Name: AHU Clg FBPD Out

OA Temperature

 

Specifies that when the module supports a Low Temperature response, the valve may be opened if OA Temperature drops below a defined setpoint. This input is used for the Low OA Temperature input temperature.

4 °C, 40 °F

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

Process ID

 

Specifies the type of cooling process that this output controller is controlling when the mode is T Control.

DA-T

Set Name: Process ID

Process Units

 

Specifies the units for the cooling PID. For this particular module, °C and °F are the only two valid values.

°C, °F

Set Name: Unit

Process Variable

 

Contains the control temperature. Either Zone temperature, discharge air temperature, or return air temperature may be connected to this input.

13 °C, 55 °F

Pump OnOff

V

Controls the circulating pump.

Off

Set Name: Off/On

Setpoint

 

Contains the desired setpoint for the process variable to be controlled to when the mode is Control.

13 °C, 55 °F

Valve OpenClose

V

Controls the two position cooling valve.

Close

Set Name: Close/Open

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