Name

Type 1

Description

Default Value

Cooling Control Status

 

Indicates current status of the controller for cooling control.

Overridden

Set Name: Control Status

Cooling isAvailable

 

Indicates cooling can be use to maintain support.

True

Cooling Mode

 

Indicates the desired mode of operation for the cooling operation.

Off

Set Name: COM Valve Out

Cooling Percent Cmd

 

Indicates cooling percent.

0%

Cooling Position

 

Provides the current Present Value of the output that this controller drives

0%

Cooling Setpoint

 

Indicates desired setpoint to which the process variable is controlled to when commanded to Control Cooling.

Indicates the value of the output when commanded to control cooling and the process variable is unreliable.

0%

Failsoft Heating Value

 

Indicates the value of the output when commanded to control heating and the process variable is unreliable

0%

Flush Position

 

Indicates the percent heating or cooling that is commanded according to the flush mode setting (heating or cooling).

100%

Heating Control Status

 

Indicates the current status of the controller for heating control.

Overridden

Set Name: Control Status

Heating isAvailable

 

Indicates heating can be use to maintain support
