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 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 Room 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 Room 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
If replacing an existing Room Controller, label the wires before removal
of the Room Controller.
Electronic controls are static sensitive devices. Discharge yourself
properly before manipulating and installing the Room Controller.
A short circuit or wrong wiring may permanently damage the Room
Controller or the equipment.
All VT7000 series Room Controllers are designed for use as operating
controls only and are not safety devices. These instruments have
undergone rigorous tests and verification prior to shipping to ensure
proper and reliable operation in the field. Whenever a control failure
could lead to personal injury and/or loss of property, it becomes the
responsibility of the user / installer / electrical system designer to
incorporate safety devices (such as relays, flow switch, thermal
protections, etc…) and/or an alarm system to protect the entire system
against such catastrophic failures. Tampering with the devices or
unintended application of the devices will result in a void of warranty.

4 | 028-0190-09 November 2015
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 Room 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 Room 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 Room 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 Room
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
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 system is setup 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.
Contact closed = Hot air / water present
Contact opened = Cold air / water present
Only used and valid if system is setup as 2.0. Parameter (Out1Conf) set as 2.0.

5 | 028-0190-09 November 2015
4. (COS) Change over analog sensor: Used for hot / cold air / water change over
switching in 2 pipe systems.
Only used and valid if system is setup as 2.0. Parameter (Out1Conf) set as 2.0.
If temperature is > 77 °F = Hot air / water present
If temperature is < 75 °F = Cold air / water present
5. (SS) Supply air sensor monitoring: Used for supply air temperature
monitoring.
Only used for network reporting of the supply air temperature. Has no internal
function in the Room Controller.

CONFIGURING AND STATUS DISPLAY INSTRUCTIONS
Status display
The Room Controller features a two-line, eight-character display. There is a low level
backlight level that is always active and can only be seen at night.
When left unattended, the Room Controller has an auto scrolling display that shows the
actual status of the system. There is an option in the configuration menu to lockout the
scrolling display and to only present the room temperature and conditional outdoor
temperature to the user. With this option enabled, no local status is given of mode,
occupancy and relative humidity.
Each item is scrolled one by one with the back lighting in low level mode. Pressing any key
will cause the back light to come on to high level. When left unattended for 10 seconds after
changes are made, the display will resume automatic status display scrolling.
To turn on the back light to high level, press any key on the front panel. The back lit display
will return to low level when the Room Controller is left unattended for 45 seconds
