The following table describes the attributes used by the 2 Pipe FBPD 2 Position Valve with Low Limit modules.

Table 1. 2 Pipe FBPD 2 Position Valve with Low Limit Attributes

Name

Type 1

Description

Default Value

Cooling Control Status

V

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

Normal

Set Name: Control Status

Cooling Mode

 

Contains the desired cooling mode of operation.

Off

Set Name: AHU Common Valve Out

Cooling Setpoint

 

Desired cooling setpoint for the process variable to be controlled to when the Cooling Mode is T Control.

13 °C, 55 °F

Damper Percent Cmd

V

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

0%

Failsoft Cooling Value

 

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

100%

Failsoft Heating Value

 

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

100%

HC-OUTSTATE (State)

V, G

Indicates the current operational mode of the output controller.

Off

Set Name: AHU Common Valve State

Heating Control Status

V

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

Normal

Set Name: Control Status

Heating Mode

 

Contains the desired heating mode of operation.

Off

Set Name: AHU Common Valve Out

Heating Setpoint

 

Desired heating setpoint for the process variable to be controlled to when the Heating Mode is T Control.

13 °C, 55 °F

Limited Max Cooling Value

 

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

100%

Limited Max Heating Value

 

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

100%

Low OA Temperature Diff

 

Differential for the Low OA Temperature function. Once the valve opens, the OA Temperature must increase Low OA Temperature Diff more than the setpoint before the valve can close.

0.5 °C, 1 °F

Low OA Temperature Setpoint

 

Contains the setpoint for the Low OA Temperature function. When the OA Temperature is below this setpoint, the valve is opened.

4 °C, 40 °F

OA Temperature

 

Used for the Low OA Temperature mode. If the OA Temperature drops below a defined setpoint the valve is opened.

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

 

Contains the type of 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 PID. For this particular module, °C and °F are the only two valid values.

°C, °F

Set Name: Unit

Process Variable

 

Control temperature. 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

SummerWinter

 

Determined if the module should heat or cool. If the input is Summer, cooling is allowed, and heating is unavailable. If the input is winter, heating is allowed, and cooling is unavailable.

Winter

Set Name: Summer/Winter

Valve OpenClose

V

Controls the two position 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)
