TR80 - Installation and Operation Guide
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. 13. 2 Occupancy control
The master controller should read the user selected occupancy mode from the ‘Effective Occu
-
pancy Mode’ register. This is the register that reflects the current effective mode and that is
used for display on the wall module.
Unless the very simple, button-only selection mode is being used, the master controller should
also write its calculated occupancy mode to the ‘master occupancy mode’ register. This is nec
-
essary for display, override functionality and to determine which overrides are allowed. It would
typically be occupied, unoccupied, standby or off.
