The following table describes the attributes used by the Autocalibration Sequence modules.
|
Name |
Description |
Default Value |
|---|---|---|
|
Autocalibrate Now |
Specifies that when this value is true, this attribute signals the Flow Calculation modules to calculate a new zero offset. |
|
|
Autocalibration Request |
This input is typically connected from the AUTOCAL-C network input (via the Balancer Override modules) to allow a user to manually trigger autocalibration. |
False |
|
AUTOCAL-STATE (Autocalibration Status) |
Current operational state of the module. |
|
|
Damper Percent Cmd |
Current position of the primary damper. This input is used to verify whether the damper is responding to this module. |
0.0 |
|
Days between Autocals |
Specifies the period between autocalibrations. If set to zero, then periodic autocalibration is not performed. It is set to zero for VAV applications with an exhaust box to prevent disturbing the flow differential controls. |
14 days (no Exhaust Box) 0 days (with Exhaust Box) |
|
Eff Stroke Time 1 |
Specifies the effective stroke time of one of the dampers controlled by the VAV application. |
120 Seconds |
|
Eff Stroke Time 2 |
Specifies the effective stroke time of one of the dampers controlled by the VAV application. |
0 Seconds |
|
Eff Stroke Time 3 |
Specifies the effective stroke time of one of the dampers controlled by the VAV application. |
0 Seconds |
|
Output Overridden |
Indicates when the controlled outputs are overridden. This stops autocalibration until all damper outputs are not overridden. |
False |
