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