Table 1. Zone Damper w 2 Position Heating Valve Attributes

Name

Type 1

Description

Default Value

Control Band

V

Indicates the control band for the MSC.

Display Units: °C, °F

Cooling Control Status

V

Indicates the saturation status of the module.

Set Name: Control Status

Cooling Mode

 

Indicates the desired mode of operation for the zone cooling operation.

Control

Set Name: MZ Zone Mode

Damper Percent Cmd

V

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

Display Units: %

Eff Minimum Off Time

V

Indicates the minimum off time used by the MSC.

Display Units: Seconds

Eff Minimum On Time

V

Indicates the minimum on time used by the MSC.

Display Units: Seconds

Eff Process Time Const

V

Indicates the effective process time constant used by the MSC.

Display Units: Seconds

Eff Process Variable

V

Indicates the process variable used by the MSC.

Display Units: °C, °F

Fast Sequence Enabled

 

Indicates if a state change should be allowed if a setpoint changes as described in the Setpoint Threshold input.

True

Heating Control Status

V

Indicates the saturation status of the module.

Set Name: Control Status

Heating Mode

 

Indicates the desired mode of operation for the zone heating operation.

Control

Set Name: MZ Zone Heating Mode

Output Overridden

 

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

False

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

Indicates the period used by the PMAC algorithm within the MSC.

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

Process Variable

 

Indicates the variable that is controlled, typically Zone Temperature.

22 °C, 72 °F

Setpoint

 

Indicates the desired nominal value for the controlled variable when the mode is Control.

22 °C, 72 °F

Setpoint Adjust

 

Indicates the user adjustment that is added to the nominal setpoint value to produce an Effective Cooling Setpoint.

0 °C, 0 °F

Setpoint Threshold

 

Indicates how much the Cooling Setpoint must Increase/Heating Setpoint must decrease to cause an immediate change from Cooling to/from Heating.

1 °C, 2 °F

Shutdown Option

 

Indicates the desired control action for the damper when the module Mode is Shutdown.

Hold Damper

Set Name: MZ Zone Configuration

Unreliable Option

 

Indicates the desired control action for the damper when the module Mode is Control, but the Process Variable is not Reliable.

Hold Damper

Set Name: MZ Zone Configuration

ZNEFFCLG-SP, ZNXEFFCLG-SP (Effective Cooling Setpoint)

V

Indicates the effective setpoint to which the module attempts to control using the zone damper.

Display Units: °C, °F

ZNEFFHTG-SP, ZNXEFFHTG-SP (Effective Heating Setpoint)

V

Indicates the effective setpoint to which the module attempts to control using the heating valve.

Display Units: °C, °F

ZNHTG-MINOFF, ZNXHTG-MINOFF (Minimum Off Time)

 

Specifies the minimum time for which the two position output should be off before it can be turned on.

120 Seconds

ZNHTG-MINON, ZNXHTG-MINON (Minimum On Time)

 

Specifies the minimum time for which the two position output should be on before it can be turned off.

ZNHTG-O, ZNXHTG-O (Heating Percent Cmd)

V

Provides the Percent command for input to the MSC.

Display Units: %

ZNHTGSHFT-SP, ZNXHTGSHFT-SP (Heating Shift)

 

Indicates the Offset value that is added to the Effective Cooling Setpoint to produce the Effective Heating Setpoint.

-2 °C, -4 °F

ZN-OUTSTATE, ZNX-OUTSTATE (State)

G, V

Indicates the current operational state of the module.

Set Name: MZ Zone Heating State

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