Table 1. Heating 2 Position Valve with DA-T Low Limit Attributes

Name

Type 1

Description

Default Value

Control Band

V

Control band for the MSC.

Set Name: Unit

Control Status

V

Current status of the controller for cooling or heating control.

Set Name: Control Status

Eff Minimum Off Time

V

Minimum off time to be used by the MSC.

Display Units: Seconds

Eff Minimum On Time

V

Minimum on time to be used by the MSC.

Display Units: Seconds

Eff Process Time Const

V

Contains the effective process time constant that is used by the MSC.

Display Units: Seconds

Eff Process Variable

V

Process Variable used by the MSC.

Set Name: Unit

Failsoft Value

 

Specifies that when the mode is set to Control and the process variable is unreliable, the output cycles to maintain this percentage duty cycle.

100.0%

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: %

HTG-MINOFF (Minimum Off Time)

 

Contains the Min Off Duration for all stages.

120 Seconds

HTG-MINON (Minimum On Time)

 

Contains the Min On Duration for all stages.

120 Seconds

HTG-O (Percent Cmd)

V

Contains a representative analog percent output on a scale of 0% to 100%.

Display Units: %

HTG-OUTSTATE (State)

V, G

Indicates the current operational mode of the output controller.

Set Name: UV Valve Out

Limited Max Value

 

Specifies that when the mode is set to Limited Max, the output cycled to maintain this percentage duty cycle.

100.0%

Low Limit Process Variable

 

Contains the process variable to be controlled when the mode is set to Control Limit.

13 °C, 55 °F

Low Limit Setpoint

 

Desired setpoint for the low limit process variable to be controlled to when the mode is Control Limit.

13 °C, 55 °F

Mode

 

Mode requested by State Selection.

Off

Set Name: UV 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%

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 the MSC.

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, °FSet Name: Unit

Process Variable

 

Specifies that when the mode is set to Control, this is the variable that is to be controlled. Typically 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
