INSTALLATION & OPERATIONS GUIDE | MICROSET 4
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 6 lists data point settings for the various operating modes and indicates the action of BV-67 in
each mode. See Table 9 on page 49 for further detail.
Office modes
Office modes are typically used in commercial use environments. Screens might not appear on the
Microset 4 in the order shown, or at all, depending on Microset 4 model, configuration, and settings.
