Description  
This icon indicates that the configuration from the station has been  
written to the device via the Asc Download action or the configuration  
from the device has been updated in the station via the Asc Upload  
action.  
Download Pending State  
This is a download pending icon. It appears when the device is  
dropped onto the Nav pane.  
Entering numeric values that are very close to the  
valid range for a given field.  
Tip  
Numeric values are stored in the application in a defined  
unit. When these values are loaded in the configuration  
wizard they may be displayed in a different unit. Each unit  
has a defined precision. Because of this difference in the  
precision and the unit, there may be loss of data when  
loading the numeric values into the wizard and when  
saving the numeric values. This loss of data is of very small  
magnitude and will not affect the functioning of the  
controller.  
When the configuration is uploaded from the device, if the  
input and output configuration in the device is different from  
the input and output configuration in the database then the  
user configured input and output names will be lost. The  
default input and output names will be displayed.  
The progress bar indicates the current progress in the  
wizard. Sometimes it may take few minutes to load the  
progress bar, and the progress bar will not give the  
accurate progress during loading.  
Each unit has a pre-defined configuration. If the user  
configures the device different from the pre-defined  
configuration, the wizard displays a warning message. The  
warning message is just to notify the user about the  
configuration. The user can ignore the warning message  
and continue with the configuration.  
You may experience this loss during the following  
scenarios.  
Setting the unit system to English and entering values  
in fields such as flow set points and temperature set  
points.  
For Example:  
Predefined configuration: A Series Fan configuration should be combined with the Pressure Independent air flow con-  
trol.  
Actual Configuration: If the user combines the Series Fan configuration with the Pressure Dependent air flow control,  
the wizard displays the following warning message.

Name  
Flow Type  
Displays the control flow algorithm used by the controller. The selection available depends on the  
Pressure Type and Box Type selected. Valid selections for this field are:  
Flow Normal: The flow is controlled to satisfy the temperature control algorithm.  
Flow Tracking: This VAV Terminal type consists of a single inlet air connection receiving its primary  
source from the conditioned space. The outlet of the terminal is connected to a return air (or exhaust  
air) system. The temperature control is turned off and the air flow is controlled to balance the flow  
between several input vav boxes and one exhaust vav box in a room. This flow type is selectable  
only when the Pressure Type is set to pressure independent.  
Shared Wall Module: The temperature control loop is turned off and the flow is controlled by the  
wall module at another master node. The NV nviShare of this controller must be bound to nvoShare  
of the master node and the information received in nviShare is used to control the air flow. The  
master node must have the temperature sensor connected to it and controls the space temperature  
using its own damper and the other dampers of all nodes bound to it. This feature is used when only  
one temperature sensor is used in a large area to control several boxes or when there is a need to  
reprogram multiple satellite controllers based on flexible floor plans.  
Wall Module Type

Setpoint  
Configure the setpoints to be used by the loop in different occupancy modes. Configure the  
minimum and maximum reset values to be used and the corresponding reset sensor values.  
Reset value to be added to the setpoint is calculated by the controller as a value between min max  
reset values in proportion to the reset sensor value.  
Control Parameters Parameters that affect the output and the loop behavior can be configured. Below are the  
configurable parameters and its descriptions.  
NOTE: If derivative time is set to zero, it disables derivative action.  
NOTE: Modulating output threshold value for activating the Auxiliary output can be con-  
figured to control the auxiliary output based on the value of PID loops modulating  
output.  
Control Parameters Configurable Parameters  
Description  
Throttling range  
This is the proportional change in the sensed variable  
required to change the control output from 0 to 100 percent.  
This needs to be configured in the engineering unit of the  
main input sensor  
Integral time  
This determines the integral gain of the PID loop. The  
greater the time in seconds, the less the integral change per  
second. A setting of 0 eliminates the integral function.  
Derivative time  
PID action  
Determines the derivative gain in a PID loop. The greater the  
time in seconds, the greater the derivative effect per second  
Direct Acting or Reverse Acting selection determines the  
behavior of the loop output. In a direct acting control loop the  
output increases as the input sensor value rises above the  
setpoint. In a reverse acting control loop the output  
increases as the input falls below the setpoint.  
Control Parameters Aux DO action  
This determines the Aux DO behavior. The Aux output can  
be configured for either continuous or intermittent operation.  
This selection applies to occupied and standby modes only.  
Unoccupied is always intermittent. In continuous operation  
the output is continuous, regardless of the operation of the  
other outputs of the loop. In intermittent operation the output  
is on only when the modulating output of the loop is greater  
than 0 or at least one of the staged outputs is on.  
Modulating control for Aux  
This option allows the Aux DO to be controlled based on the  
value of the loops modulating output.  
Modulating output threshold for Aux Modulating output threshold value for controlling the  
Auxiliary output. The Aux DO is activated if the PID  
modulating output is greater than the threshold value  
Aux output minimum off time  
The auxiliary digital output minimum off time.  
NOTE: When staged outputs are configured this value  
must be configured to be less than (Cycler and  
stager interstage minimum on time - Aux output  
run on time).  
Control Parameters Aux output run on time  
The auxiliary digital output run-on time. A value of 0 disables  
the run-on time. This is typically used when the AuxDo is  
configured for intermittent operation.  
For example, If the AuxDO is controlling the fan, this  
parameter can be used to keep the fan running for certain  
duration after the cooling or heating process has stopped.  
Minimum off time  
This is the minimum off time for the staged outputs  
Cycler and stager interstage  
minimum on time  
This is minimum amount of time a lower numbered stage  
must be on before the next stage can turn on.  
Minimum on time  
This is the minimum on time for the Aux DO and staged  
outputs

16. SENSOR CALIBRATION  
Use this page for sensor calibration in an Stryker VAV device on the LON network. Using Sensor Calibration feature, you can  
correct the input values to the controller. This action can be performed with the device in online mode. The controller must be in a  
commissioned state. While performing Sensor Calibration, the device should not be used by another application. You can  
calibrate only analog inputs to the controllers.  
To calibrate:  
Step  
Action  
1
2
From the Nav menu, choose Station > Driver > LON network > AscLonVAV device.  
Right-click the device and choose Views > Sensor Calibration from device items. The Sensor  
Calibration screen appears.

Name  
Sensor Name  
Actual Value  
Displays the sensor names.  
Displays the current value of the sensor as read by the controller.  
Enter the calibrated value.  
Calibrated Value  
Offset Value  
Once you click Calibrate, the offset value appears. Offset value is a difference between  
Actual value and Calibrated value.  
Tip  
In this case  
To clear the Offset value for any of the configured  
sensors:  
Calculate the calibrated value using the below formula, type it  
in the Calibrated value field and click Calibrate.  
The Actual value = -324.742  
Old Offset value = 775.102  
Calibrated Value = Actual Value - Old Offset Value  
= -324.742-775.102  
Calibrated Value = Actual Value - Old Offset Value  
For Example:  
= -1099.844 F  
If the configured Sylk bus sensor reads the room temperature  
as 79.88 F and you want to calibrate it to 85.5 F. By mistake if  
you type the calibrated value as 855 F, the offset value will be  
calculated as 775.102 F. This will display the Actual value as -  
324.742 which is abnormal.  
If you type this value in the Calibrated Value field and click  
Calibrate, the Offset value will be cleared.  
RELATED TOPICS  
If you find any abnormal value like this and you want to clear  
the offset value. Calculate the Calibrated value as shown  
below and type the calculated value in the Calibrated Value  
field.
