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 on 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.
BI 2
Binary input no.2 configuration
Default value = None (None): No function will be associated with the input. Input can be used for remote
network monitoring.
(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
