Configurable BI, RBI, UI, RUI inputs overview
BI1,
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
BI2,
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
RUI1,
Remote universal input #1 on VC3xxxX can be
configured for the following functions:
3. (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
4.
(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
3. (COC/NH) Change over dry contact. Normally Heat:
Used for hot
/
cold water change over switching in 2
pipe systems.
•
Contact closed = Cold water present
•
Contact opened = Hot water present
Only used and valid if system is setup as 2 pipes.
Parameter ( Pipe No ) set as 2 pipes.
4. (COC/NC) Change over dry contact. Normally Cool:
Used for hot
/
cold water or air change over switching in
2 pipe systems.
•
Contact closed = Hot water present
•
Contact opened = Cold water present
Only used and valid if system is setup as 2 pipes.
Parameter ( Pipe No ) set as 2 pipes.
5. (COS) Change over analog sensor:
Used for hot
/
cold water or air change over switching in 2 pipe
systems.
Only used and valid if system is setup as 2 pipes.
Parameter ( Pipe No ) set as 2 pipes.
•
If temperature is > 77 °F = Hot water present
•
If temperature is < 75 °F = Cold water present
RBI2,
Remote binary input #2 on VC3xxxX can be
configured for the following functions:
1. (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
2.
(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
