CONFIGURABLE BI/UI 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 the applied PIR function and configuration. Application information and examples are available on the document: APP-PIRGuide-Exx. This document will provide the installers and system designers with detailed examples of 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 and 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 into 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 the 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 monitors 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 into the AC unit control card, which provides an alarm in case of malfunction.
    • Contact opened = No alarm
    • Contact closed = Alarm displayed

Universal input #3 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 the system is set up as 2.0. Parameter ( Out1Conf ) set as 2.0.
  3. (COC/NC) Change over dry contact. Normally Cool: Used for hot/cold air/water change over switching in 2 pipe systems.
