This may be desired if t he BM S is running a reset routine on the setpoint s and would
like to revert to a default state if communication is lost. It is recommended to be used
with ret urn to default enabled, and a known relinquish default is saved.
When this box is checked by a user, the controller will write the present value of
variables to the relinquish default for all binary and analog value BACnet objects that
are comm andable. The function operat es in the background and takes approximately
30 seconds to complete.
This is desired to save any Test and Balance settings adjusted locally on the controller
to be the BACnet relinquish default values. Alternatively, these values could be read
and written to the relinquish default variables by the BM S system.
BINARY TEXT
If for any reason, the state text is missing from binary objects, checking this
box will cause the controller to re-write the act ive and inactive text values.
