changed.
Or
View the switch that is to be adjusted in the Device Viewer, right-click the switch, and click Adjust Point.

3.3.2.2 Adjust a Switch (Digital Value) in a BACnet Device
Digital values in BACnet devices are represented in 963 as switches, these can be adjusted from a schematic page or
from the Device Viewer.
To adjust a switch (digital value) in a BACnet device:
1. Display the page containing the switch representing the digital value that is to be adjusted, and click the
button that enables it to be changed.
Or
View the switch representing the digital value that is to be adjusted, in the Device Viewer, right-click the
switch, and click Adjust Point.
The Switch Adjuster dialogue box is displayed.
2. Select the Adjust switch status option.
3. Click OK. The Adjust Point dialogue box is displayed.

Important: When 963 adjusts a value in a BACnet device it writes the value into the value's priority array.
The value will remain in the array, and be used when it is the highest. Therefore making the adjustment does
not mean that it will be the value that is used. If required the 963's adjustment can be removed from the
array by relinquishing control.
