The following table describes the attributes used by the Heating Staged Outputs module.

Table 1. Heating Staged Outputs Attributes

Name

Type 1

Description

Default Value

BOXHTG-O, HTG-O, or SUPHTG-O (Percent Cmd)

V

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

Display Units: %

Control Band

V

Control band for the MSC.

Display Units: °C, °F

Control Status

V

Current status of the controller for heating control. See the PID section for more information.

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

Contains the Process Variable used by the MSC.

Display Units: °C, °F

Failsoft Value

 

Specifies that when the mode is set to Failsoft, the output cycles to maintain this percentage duty cycle.

0.0%

HeatingCooling

 

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

Heating

Set Name: Heating/Cooling

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 or SUPHTG-MINOFF (Minimum Off Time)

 

Contains the Min Off Duration for all stages.

120 Seconds

HTG-MINON or SUPHTG-MINON (Minimum On Time)

 

Contains the Min On Duration for all stages.

120 Seconds

HTG-OUTSTATE or SUPHTG-OUTSTATE (State)

V, G

Current operational mode of the output controller.

Set Name: COM Staged Out

Instant Shutdown

V

Contains the indication to the MSC to shut off all outputs instantly.

 

Limited Max Value

 

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

100.0%

Max Capacity Fraction

 

Ratio of the largest stage to the sum of all the stages.

1.0

Mode

 

Mode requested by State Selection.

Off

Set Name: COM Staged 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

Contains the period used by the PMAC algorithm portion of the MSC Controller.

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. Typically connected to the Zone Temperature.

22 °C, 72 °F

Proof of Airflow

 

Specifies that when set to False or True, the controller operates as normal. When set to Fault, the controller transitions to an instant off state.

True

Set Name: False/True/Fault

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)
