Type 1


Default Value

Control Status


Indicates the saturation status of the module.

Set Name: Control Status

Damper Percent Cmd


Provides the output for the mixing dampers, with 0% corresponding to maximum heating and 100% corresponding to maximum cooling.

Display Units: %



Indicates the desired mode of operation for the module.


Set Name: MZ Zone Mode

Output Overridden


Indicates when the actual output controlled by this output is overridden by a user.


Output Position


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


PID Tuning Reset


Causes the PID objects to reset their tuning parameters to the default based on the appropriate Process ID.


Set Name: PID Tuning Reset

Process Units


Specifies the units for the PID. For this particular module, °C and °F are the only two valid values.
