The following table describes the attributes used by the Cooling Proportional Valve with Dehumidification modules.

Table 1. Cooling Proportional Valve with Dehumidification Attributes

Name

Type 1

Description

Default Value

CLG-OUTSTATE (State)

G, V

Current operational state of the output controller.

Off

Set Name: AHU Clg Valve Out

Compensator Clg Cmd

 

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

0.0

Display Units: %

Cooling Control Status

V

Contains the current saturation status of the controller.

Normal

Set Name: Control Status

Cooling Percent Cmd

V

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

0%

Dehum Process ID

 
Specifies the type of process that this output controller is controlling when the mode is H Control:
  • Discharge Air Humidity (DA-H)
  • Return Air Humidity (RA-H)
  • Exhaust Air Humidity (RA-H)
  • Zone Air Humidity (ZN-H)
  • Zone Air Humidity Compensated (ZN-H LC)

RA-H

Set Name: Process ID

Failsoft Value

 

Specifies the output when the mode is set to Failsoft.

100%

Flush Position

 

Specifies the output when the mode is set to Water Flush.

100%

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% RH

Humidity Setpoint

 

Contains the dehumidification Setpoint.

50% RH

Limited Max Value

 

Specifies the output when the mode is set to Limited Max.

100%

Low OA Temperature Diff

 

Indicates the differential for the Low OA Temperature mode. Once the valve is opened to allow water to flow through the coil during low OA temperature conditions, the OA temperature must increase above the OA Temperature Setpoint by the Low OA Temperature Diff before the valve can close.

0.5 °C, 1 °F

Low OA Temperature Position

 

Specifies the output when the mode is set to Low OA Temperature.

100%

Low OA Temperature Setpoint

 

Indicates the setpoint for the Low OA Temperature mode. When the OA Temperature falls below this setpoint, the valve opens.

4 °C, 40 °F

Mode

 

Mode requested by State Selection.

Off

Set Name: AHU Clg Valve Out

OA Temperature

 

Indicates the Outside Air Temperature.

4 °C, 40 °F

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

Process ID

 

Specifies the type of process that this output controller is controlling when the mode is T Control:

  • Discharge Air Temperature (DA-T)
  • Return Air Temperature (ZN-T)
  • Zone Air Temperature (ZN-T)
  • Exhaust Air Temperature (ZN-T)
  • Zone Air Temp Compensated (ZN-T LC)

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

 

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.

13 °C, 55 °F

Pump OnOff

V

Controls the circulating pump.

Off

Set Name: Off/On

Setpoint

 

Desired setpoint for the process variable to be controlled to when the mode is set to 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)
