The following table describes the attributes used by the Cooling 2 Position Valve modules.
|
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-MINOFF (Minimum Off Time) |
Displays Min Off Duration for all stages. |
120 Seconds |
|
|
CLG-MINON (Minimum On Time) |
Displays Min On Duration for all stages. |
120 Seconds |
|
|
CLG-O (Percent Cmd) |
V |
Controls the single actuator that is providing cooling. |
Display Units: % |
|
CLG-OUTSTATE (State) |
G, V |
Contains the current operational state of the output controller. |
Set Name: COM Valve Out |
|
Control Band |
V |
Control band for the MSC. |
Display Units: °C, °F |
|
Control Status |
V |
Current saturation status of the controller. |
Overridden Set Name: Control Status |
|
Eff Minimum Off Time |
V |
Minimum off time used by the MSC. |
Display Units: Seconds |
|
Eff Minimum On Time |
V |
Minimum on time used by the MSC. |
Display Units: Seconds |
|
Eff Process Time Const |
V |
Contains the effective process time constant used by the MSC. |
Display Units: Seconds |
|
Eff Process Variable |
V |
Process Variable used by the MSC. |
Display Units: °C, °F |
|
Failsoft Value |
Value of the output when commanded to Failsoft. |
0.0% |
|
|
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 commanded to Limited Max, this is the value the Percent Cmd is set to. |
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. |
0.0% |
|
|
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 |
|
|
PMAC Period |
V |
Period used by the PMAC algorithm portion of theMSC. |
Display Units: Seconds |
|
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 |
