2. Modbus only: With this setting, the occupancy button on the wall module is disabled.
Master controller determines the occupancy mode.
3. Modbus with override from button: In this case, the master controller determines the
occupancy mode based on a time schedule, presence detector and/or other inputs.
However, the user may be allowed to override the current mode using the occupancy
button.This allows user to select further modes such as holiday or bypass.

3. 10. 2 Occupancy control

Unless the very simple, button-only selection mode is being used, the master controller
should write its calculated occupancy mode to the 'master occupancy mode' register. This
is necessary for display, override functionality and to determine which overrides are
allowed. It would typically be occupied, unoccupied, standby or off.
The master controller should read the user selected occupancy mode from the 'Effective
Occupancy Mode' register. This is the register that reflects the current effective mode and
that is used for display on the wall module.
