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

Table 1. Zone Damper w Proportional Heating Valve Attributes

Name

Description

Default Value

Compensator Heating Cmd

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

0.0

Display Units: %

Cooling Control Status

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

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

Display Units: %

Fast Sequence Enabled

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

True

Flush Position

Indicates the valve position when Heating Mode is Water Flush.

100%

Heating Control Status

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

Heating Percent Cmd

Indicates the Percent command for the heating valve.

Display Units: %

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

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)

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)

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

Display Units: °C, °F

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)

Indicates the current operational state of the module.

Set Name: MZ Zone Heating State

See Primary States (Zone Damper w Proportional Heating Valve).
