The following table describes the attributes used by the Cooling Staged Outputs with Dehumidification modules.

Table 1. Cooling Staged Outputs with Dehumidification Attributes

Name

Type 1

Description

Default Value

CLG-MINOFF (Minimum Off Time)

 

Contains the Min Off Duration for all stages.

120 Seconds

CLG-MINON (Minimum On Time)

 

Contains the Min On Duration for all stages.

120 Seconds

CLG-O (Cooling Percent Cmd)

V

Controls the cooling device. The device is commanded from 0% to 100%.

Display Units: %

CLG-OUTSTATE (State)

G, V

Current operational mode of the output controller.

Set Name: AHU Clg Staged Out

Control Band

V

Control band for the MSC.

Display Units: °C, °F

Cooling Control Status

V

Current saturation status of the controller.

Set Name: Control Status

Dehum Process ID

 

Specifies the type of process that this output controller is controlling when the mode is H Control.

RA-H

Set Name: Process ID

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 that is used by the MSC.

Display Units: Seconds

Eff Process Variable

V

Contains the Process Variable used by the MSC.

Display Units: °C, °F

Humidity Process Variable

 

Value of the relative humidity being measured by the humidity sensor. It is used as the process variable in the dehumidification control.

50.0% RH

Humidity Setpoint

 

Contains the dehumidification Setpoint.

50.0% RH

Instant Shutdown

V

Indicates to the MSC to shut off all outputs instantly.

 

Limited Max Value

 

Defines the proportional valve position when the module is in the Limited Max state.

100.0%

Max Capacity Fraction

 

Contains the ratio of the largest stage to the sum of all the stages.

1.0

Mode

 

Mode requested by State Selection.

Off

Set Name: AHU Clg Staged Out

Output Overridden

 

Indicates when the actual output that is controlled by this output controller 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

Specifies the period used by the PMAC algorithm portion of the MSC.

Display Units: Seconds

Process ID

 

Specifies the type of process that this output controller is controlling when the mode is H Control.

DA-T

Set Name: Process ID

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

 

Control temperature. Either Zone temperature, discharge air temperature, return air temperature or preheat temperature may be connected to this input.

13 °C, 55 °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 Control.

13 °C, 55 °F

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