The following table describes the attributes used by the Zone Damper w Staged Heating modules:

Table 1. Zone Damper w Staged Heating 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 Mode

Instant Shutdown

V

Indicates to the MSC to shut off all outputs without delay.

Boolean

Max Capacity Fraction

 

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

1.0

Output Overridden

 

Indicates when the actual output controlled by this output 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

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 and the 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

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.

120 Seconds

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

V

Indicates 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.
