Viconics VBZS Engineering Guide Specifications - Manual (Page 9)

The zone controller shall have a binary input that can be configured as follows:
BI1 Binary input no.1 configuration
Default: None
(None): No function will be associated with the input. Point
can still be monitored through the BACnet network.
(Motion NO): Used in Occupied Mode only to toggle from the
Occupied setpoints to the Stand-By setpoints when no motion
is detected for 60 minutes at the zone.
As soon as motion is detected at the zone, the Occupied
setpoints resumes.
Contact opened = No motion detected.
Contact closed = Motion detected
(Motion NC): Used in Occupied Mode only to toggle from the
Occupied setpoints to the Stand-By setpoints when no motion
is detected for 60 minutes at the zone.
As soon as motion is detected at the zone, the Occupied
setpoints resumes.
Contact opened = Motion detected.
Contact closed = No motion detected
The zone controller shall be capable of receiving the outdoor air temperature signal from the RTU
controller to lockout (if necessary) the zone’s analog reheat and/or the zone’s perimeter heating.
The zone controller shall have configurable temporary or permanent local override setpoints.
When the “temporary setpoints” mode is enabled, once the temporary occupancy timer expires,
the setpoints will revert back to their default values.
The zone controller shall have adjustable maximum heating and minimum cooling setpoints to
prevent locking conditions at the Rooftop Unit controller by having setpoints that are not
reachable.
