Step 5: Add a BACnet Time Clock microblock
The BACnet Time Clock microblock enables the ZS Sensor's override function and controls its green Occupied LED.
From the Control microblock menu, add a BACnet Time Clock with TLO and Override Status microblock
to determine how the user can interact with your schedule through the ZS Sensor. Enter the following information
in the Property Editor.
Enable Rnet Check to allow this microblock to communicate its value(s) to and from a ZS
sensor.
Allow 'Continuous' Override Check to allow a user to force a zone into an occupied state for an indefinite
amount of time. The override remains in effect until the schedule transitions
to occupied or until a user manually clears it by pressing the sensor's
button twice.
Allow Force Unoccupied Check to allow a user to save energy by forcing the zone into an unoccupied
state. To force unoccupied, a user holds a ZS sensor's
button for at least 3
seconds. This override state remains in effect until the schedule transitions to
unoccupied or until a user presses the sensor's
button.
Force Unoccupied without
Delay
Check to allow a user to force a zone to unoccupied immediately instead of
the normal 3-second delay.
NOTE This feature is unavailable if Allow TLO Set During Occupied is
checked.
Allow TLO Set During Occupied Check to allow a user to activate a timed local override while the zone is
scheduled occupied. This allows a user to extend the zone's occupied time
without the zone having to go unoccupied first.
NOTE This feature is unavailable if Force Unoccupied without Delay is
checked.
Timed Local Override
Increment Minutes the microblock adds to the zone's occupied time for each press of the
zone's local override button or switch.
Maximum Duration Maximum value (up to 960 minutes) the microblock outputs regardless of
additional pulses from the controller's input.
Optional tab - Allow for External
Scheduling
See External Scheduling.
During an override, the bottom of the screen will show and the minutes remaining in the override.
