BI1
Binary input no.1 configuration
Default value = None (None): No function will be associated with the input
(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
(Motion NO) or (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
(Window) EMS: Forces the system to disable any current heating or cooling action
by the thermostat. 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 thermostat to indicate to the local tenant that the
door/window needs to be closed for cooling or heating to resume.
* these settings will disable the local override function on the thermostat.
BI2
Binary input no.2 configuration
Default value = None (None): No function will be associated with the input
(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 thermostat 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
(RemOVR): temporary occupancy remote override contact. This function disables
the central button override function on the thermostat. 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.
(Filter): a backlit flashing Filter alarm will be displayed on the thermostat 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
(Service): a backlit flashing Service alarm will be displayed on the thermostat 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
