When the SMART 3000 is in Unoccupied mode, the display will go completely
blank except for the words Unoccupied in the top left. If the optional SMART-R-
O1H hallway panel is installed its display backlight will go out to let housekeeping
know the room is empty. ModBus register 40004 also indicates occupancy status.
Doorbell
Figure 13
A built-in doorbell feature is included with the SMART 3000 thermostat. This is
normally activated by the optional outside door station as described above or
via ModBus data link. In circumstances where this is not convenient, the Digital
Input (DI) terminals can be reassigned as a doorbell activation switch with the
digital input options detailed in the Installer Menu. See page 40. Simply place
a momentary volt free switch across DI and Com 0-V terminals to activate the
doorbell. Once pressed, the doorbell will chime for about 10 seconds.
