BI 1
Binary input no.1
configuration
Default value = None (None): No function will be associated with the input. Input can
be used for remote network monitoring.
(Rem NSB): remote NSB timer clock input. The scheduling will
now be set as per the binary input. It provides low cost setback
operation via a dry contact
 Contact opened = Occupied
 Contact closed = Unoccupied
(Motion NO) or (Motion NC): Advanced PIR occupancy
functions using a Normally Open (NO) or Normally Closed
(NC) remote PIR motion sensor. Occupancy mode is now set
as per applied PIR function and configuration. Application
information and examples are available in document: APP-
PIR-Guide-Exx. This document will provide the installers and
system designers with detailed examples on applications,
parameter configuration information, sequence of operation,
troubleshooting and diagnostic help required for the proper
usage of the PIR accessory covers
(Window) EMS: Forces the system to disable any current
heating or cooling action by the Terminal Equipment
Controller. The mode stays the same and the current setpoints
are the same Occupied setpoints. Only the outputs are
disabled. There is a Door/Window alarm displayed on the
Terminal Equipment Controller to indicate to the local tenant
that the door/window needs to be closed for cooling or heating
to resume.
* These settings will disable the local override function on the
Terminal Equipment Controller.

Binary input no.2
configuration
Default value = None

(None): No function will be associated with the input
 (Door Dry) Door contact & Motion detector: This configuration
is only functional if binary input #1 is set to Motion NO or
Motion NC or a PIR accessory cover is used.

With this sequence enabled, the occupancy is now dictated
through those 2 inputs. Any motion detected will set the zone
to occupied status. The zone will remain permanently in
occupied mode until the door contact switch opens
momentarily. The Terminal Equipment Controller will then go
in stand-by mode. If more movements are detected, the
occupied mode will resume. While the door is opened, any
movements detected by the remote PIR sensor or the PIR
accessory cover will be ignored. Use a Normally Closed
contact switching device.
 Contact opened = Door opened
 Contact closed = Door closed

(RemOVR): temporary occupancy remote override contact.
This function disables the central button override function on
the Terminal Equipment Controller. The override function is
now controlled by a manual remote momentarily closed
contact. When configured in this mode, the input operates in
a toggle mode.

It is now possible to toggle between unoccupied & occupied
setpoints for the amount of time set by parameter (TOccTime)
temporary occupancy time.
