Enabling operating modes
Combinations of values for BVs 64, 65, 80, and 81 control operating modes. In
each mode, BV-67 (a read-only point) reports occupied/unoccupied status. Use
this data point in DDC as a flag to control occupied and unoccupied operating
sequences.
Table 5 lists data point settings for the various operating modes and indicates the
action of BV-67 in each mode. See Table 8 on page 43 for further detail.

Set BV-64 ON and BV-65, BV-80, and BV-81 OFF. The LCD displays the

occupied setpoints.
