The following table describes the attributes used by the Cooling Proportional Valve modules.

Table 1. Cooling Proportional Valve Attributes

Name

Type 1

Description

Default Value

CLG-ABSEFFORT (Cooling Absolute EWMA Effort)

 

Provides an EWMA based on the absolute value of (Current Present Value - Last Present Value). The PID computes this value.

0.0

Display Units: %

CLG-ABSERROR (Cooling Absolute EWMA Error)

 

Provides an EWMA based on the absolute value of (Setpoint - Process Variable). The PID computes this value.

0.0

Display Units: °C, °F

CLG-ERROR (Cooling EWMA Error)

 

Provides an EWMA based on the difference of (Setpoint - Process Variable). The PID computes this value.

0.0

Display Units: °C, °F

CLG-EWMA (Cooling EWMA Present Value)

 

Provides an EWMA of the Present Value. The PID computes this value.

0.0

Display Units: %

CLG-OUTSTATE (State)

G, V

Current operational state of the output controller.

Set Name: COM Valve Out

Compensator Cmd

 

Specifies the analog percent output that controls the single actuator that provides cooling. This output incorporates the Lead Compensator.

0.0

Display Units: %

Control Status

V

Contains the current saturation status of the controller.

Overridden

Set Name: Control Status

Failsoft Value

 

Value of the output when commanded to Failsoft.

0.0%

Flush Position

 

Value of the output when commanded to Water Flush. This value is sent directly to the Percent Cmd output.

100,0%

HeatingCooling

 

Configures the module to be either compatible with a heating source or a cooling source.

Cooling

Set Name: Heating/Cooling

Limited Max Value

 

Specifies that when the module is commanded to Limited Max, this is the value of the Percent Cmd.

100,0%

Mode

 

Mode requested by State Selection.

Off

Set Name: COM Valve Out

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%

Percent Cmd

V

Controls the single actuator that is providing Cooling.

Display Units: %

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 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

 

Specifies that when the mode is set to Control, this is the variable that is controlled. This value typically is connected to the Zone Temperature.

22 °C, 72 °F

Setpoint

 

Desired setpoint for the process variable to be controlled to when the mode is set to Control.

22 °C, 72 °F

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