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
Contact closed = Alarm displayed
5. (Service): a backlit flashing Service alarm will be displayed on the Terminal
Equipment Controller LCD screen when the input is energized. It can be tied in
to the AC unit control card, which provides an alarm in case of malfunction.
Contact opened = No alarm
Contact closed = Alarm displayed
