Control band for the MSC. |
Display Units: °C, °F |
Cooling Control Status |
V |
Current saturation status of the controller. |
Set Name: Control Status |
Dehum Process ID |
Specifies the type of process that this output controller is controlling when the mode is H Control. |
RA-H Set Name: Process ID |
|
Eff Minimum Off Time |
V |
Minimum off time used by the MSC. |
Display Units: Seconds |
Eff Minimum On Time |
V |
Minimum on time used by the MSC. |
Display Units: Seconds |
Eff Process Time Const |
V |
Contains the effective process time constant that is used by the MSC. |
Display Units: Seconds |
Eff Process Variable |
V |
Contains the Process Variable used by the MSC. |
Display Units: °C, °F |
Humidity Process Variable |
Value of the relative humidity being measured by the humidity sensor. It is used as the process variable in the dehumidification control. |
50.0% RH |
|
Humidity Setpoint |
Contains the dehumidification Setpoint. |
50.0% RH |
|
Instant Shutdown |
V |
Indicates to the MSC to shut off all outputs instantly. |
|
Limited Max Value |
Defines the proportional valve position when the module is in the Limited Max state. |
100.0% |
|
Max Capacity Fraction |
Contains the ratio of the largest stage to the sum of all the stages. |
1.0 |
|
Mode |
Mode requested by State Selection. |
Off Set Name: AHU Clg Staged Out |
|
Output Overridden |
Indicates when the actual output that is controlled by this output controller 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 |
Specifies the period used by the PMAC algorithm portion of the MSC. |
Display Units: Seconds |
Process ID |
Specifies the type of process that this output controller is controlling when the mode is H Control. |
DA-T Set Name: Process ID |
|
Process Units |
Specifies the units for the PID. For this particular module, °C and °F are the only two valid values. |
°C, °F Set Name: Unit |
|
Process Variable |
Control temperature. Either Zone temperature, discharge air temperature, return air temperature or preheat temperature may be connected to this input. |
13 °C, 55 °F |
|
Proof of Airflow |
Specifies that when set to False or True, the controller operates as normal. When set to Fault, the controller transitions to an instant off state. |
True Set Name: False/True/Fault |
|
Setpoint |
Desired setpoint for the process variable to be controlled to when the mode is Control. |
13 °C, 55 °F |
