INSTALLATION

Remove the security screw on the bottom of
Terminal Equipment Controller cover.

 Open unit by pulling on the bottom side

of Terminal Equipment Controller (fig.

1).

 Remove wiring terminals from sticker.
 Please read the FCC ID and IC label

installed in the cover upon removal of
cover for the wireless products.

Location

1. Should not be installed on an outside
wall.

2. Must be installed away from any direct
heat source.

3. Should not be installed near an air
discharge grill.

4. Should not be affected by direct sun
radiation.

5. Nothing should restrict vertical air
circulation to the Terminal
Equipment Controller.

Installation

1. Swing open the Terminal Equipment
Controller PCB to the left by
pressing the PCB locking tabs (fig.

2).

2. Pull out cables 6” out from the wall.

3. Wall surface must be flat and clean.

4. Insert cable in the central hole of the
base.

5. Align the base and mark the location
of the two mounting holes on the
wall. Install proper side of base up.

6. Install anchors in the wall.

7. Insert screws in mounting holes on
each side of the base (fig. 2).

8. Gently swing back the circuit board
on the base and push on it until the
tabs lock it.

9. Strip each wire 1/4 inch from end.

10. Insert each wire according to wiring
diagram.

11. Gently push excess wiring back into
hole (fig. 3).

12. Re-Install wiring terminals in their
correct locations (fig. 3).

13. Re-install the cover (top side first) and gently push extra wire length back into the

 If replacing an existing Terminal Equipment Controller, label the wires

before removal of the Terminal Equipment Controller.

 Electronic controls are static sensitive devices. Discharge yourself

properly before manipulating and installing the Terminal Equipment
Controller.

 A short circuit or wrong wiring may permanently damage the Terminal

Equipment Controller or the equipment.

 All VT7000 series Terminal Equipment 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.

hole in the wall.

14. Install security screw.

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 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 & 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

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 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

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 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.

4 | PIR Ready VT7200 Series-Installation Guide

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 Terminal Equipment Controller.
