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: %

Compensator Cmd

 

Controls the heating/cooling valve. The valve is commanded from 0% to 100%. This output incorporates the Lead Compensator.

0.0

Display Units: %

Cooling Control Status

V

Current saturation status of the controller when SummerWinter is set to Summer.

Overridden

Set Name: Control Status

Cooling Mode

 

Cooling mode requested by State Selection.

Off

Set Name: COM Valve Out

Cooling Percent Cmd

V

Analog percent output that controls the single actuator when SummerWinter is set to Summer.

Display Units: %

Cooling Setpoint

 

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

23 °C, 74 °F

Failsoft Cooling Value

 

Value of the output when the cooling mode is set to Failsoft.

0.0%

Failsoft Heating Value

 

Value of the output when the heating mode is set to Failsoft.

0.0%

Flush Position

 

Value the Percent Cmd is commanded to when the cooling or heating mode is set to Water Flush. This value is sent directly to the Percent Cmd output.

100.0%

HC-OUTSTATE (State)

G, V

Current operational state of the output controller.

Set Name: FC 2or4-Pipe Out State

Heating Control Status

V

Current saturation status of the controller when SummerWinter is set to Winter.

Overridden

Set Name: Control Status

Heating Mode

 

Heating mode requested by State Selection.

Off

Set Name: COM Valve Out

Heating Percent Cmd

V

Controls the single actuator when SummerWinter is set to Winter.

Display Units: %

Heating Setpoint

 

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

21 °C, 70 °F

HTG-ABSEFFORT (Heating 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: %

HTG-ABSERROR (Heating 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

HTG-ERROR (Heating EWMA Error)

 

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

0.0

Display Units: °C, °F

HTG-EWMA (Heating EWMA Present Value)

 

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

0.0

Display Units: %

Limited Max Position

 

Specifies that when the cooling or heating mode are set to Limited Max, this is the value for the Percent Cmd.

100.0%

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

Indicates the current capacity requested by either the Cooling Percent Cmd or the Heating Percent Cmd.

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 cooling or heating mode are set to Control, this is the variable that is controlled. Typically connected to the Zone Temperature.

22 °C, 72 °F

SummerWinter

 

Specifies whether the supply is currently configured to deliver cooling (Summer) or heating (Winter).

Winter

Set Name: Summer/Winter
