CONFIGURABLE BI/UI UNIVERSAL INPUTS OVERVIEW
Universal input #16 can be configured for the following binary
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-
SE8xxx. 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 onboard PIR sensor.
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
Universal input #17 can be configured for the following binary
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 an onboard
PIR sensor 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 onboard PIR sensor 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 Filter alarm short text message will be
displayed on the Terminal Equipment Controller
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 Service alarm short text message
will be displayed on the Terminal Equipment
Controller 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
Universal input #19 can be configured for
the following functions:
1. (None): No function will be associated with the
input
2. (COC/NH) Change over dry contact.
Normally Heat: Used for hot / cold air / water
change over switching in 2 pipe systems.
Contact closed = Cold air/water present
Contact opened = Hot air/water present
Only used and valid if Room Controller is set
up for a 2 pipe system.
3. (COC/NC) Change over dry contact.
Normally Cool: Used for hot / cold air / water
change over switching in 2 pipe systems.
Contact closed = Hot air/water present
Contact opened = Cold air/water
present
Only used and valid if Room Controller is set
up for a 2 pipe system.
4. (COS) Change over analog sensor: Used for
hot / cold air / water change over switching in 2
pipe systems.
Only used and valid if Room Controller is set
up for a 2 pipe system.
If temperature is > 77 °F = Hot air / water
present
If temperature is < 75 °F = Cold air / water
present
