Reading System Points
To verify that the system point is being written to within the refresh time specified (value varies by point), the i-
Vu® Open controller clears any value that is written, once it has been processed by the controller and returned
the system point to its default value. Therefore, a BAS should never read back the system point's value to confirm
the commanded value was successfully received. To confirm a write, refer to the table below for the corresponding
control point that should be read.
NOTE A confirmin g “read” should take place at least 30 seconds following the “write” to verify that the write has
been processed by the controller.
