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.
