INPUTS OVERVIEW
Binary input #1 can be configured for the following functions:
1.
(None): No function will be associated with the input
2.
(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
3.
(Motion NO) and (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
4.
(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. Use NC contact.
Contact opened = System disabled with local Window alarm
Contact closed = System enabled
Binary input #2 can be configured for the following functions:
1.
(None): No function will be associated with the input
2.
(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
3.
(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.
4.
(Filter): a backlit flashing Filter alarm will be displayed on the Terminal
Equipment Controller LCD screen when the input is energized. It can be tied to a
differential pressure switch that monitor filters
Contact opened = No alarm
