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 base in
proper orientation. Arrow on
base should be facing 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.
2 | VT7682S Series-Installation Guide
10. Insert each wire according to wiring diagram.
When 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.
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 hole in the wall.
14. Install security screw.

Status display
The Terminal Equipment Controller features a two-line, eight-character display. There is a
low level backlight that is always active and can only be seen at night.
When left unattended, the Terminal Equipment Controller has an auto scrolling display
that shows the current status of the system.
Each item is scrolled sequentially with the back lighting in low level mode. Pressing any
key will cause the back light to come on to high level.
Manual scrolling of each menu item is achieved by pressing the Yes (scroll) key
repetitively. The last item viewed will be shown on the display for 30 seconds before
returning to automatic scrolling. Temperature is automatically updated when scrolling is
held.
Sequence of auto-scroll status display:
** X, Y, Z is the MAC address of the zone that has the alarm.
Outdoor air temperature
Outdoor air temperature display is only enabled when outdoor air temperature sensor is
connected.
A maximum range status display of 50 °C (122 °F) indicates a shorted sensor.
Associated functions, such as mode lockouts and economizer function are
automatically disabled.
A minimum range status -40 °C (-40 °F) is not displayed and indicates an opened
sensor or a sensor not connected. Associated functions, such as mode lockouts and
economizer function are automatically disabled.

advance to the next menu item. Can also be used to toggle between heating
and cooling setpoints.
The MENU key is used to access the Main User Menu or exit the menu.
The down arrow key is used to decrease temperature setpoint and to adjust
the desired values when configuring the Terminal Equipment Controller.
The up arrow key is used to increase temperature setpoint and to adjust the
desired values when configuring the Terminal Equipment Controller.

During an alarm message display, the back lit screen will light up at the same time as
the message and shut off during the rest of the status display.
Two alarms maximum can appear at any given time.
The range of zones that can be in alarm is 1 to 253.
USER INTERFACE
User configuring instructions menu
The VT7682S series Terminal Equipment Controller
feature an intuitive, menu-driven, back-lit LCD

events, system mode etc...
It is possible to bring up the user menu at any time
by depressing the MENU key. The status display automatically resumes after exiting the
user-configuring menu.
If the user pauses at any given time during configuring, Auto Help text is displayed to help
and guide the user through the usage and configuring of the Terminal Equipment
Controller.
Local keypad interface
Each of the sections in the menu is accessed and configured using 5 keys on the
Terminal Equipment Controller cover.
The priority for the alarms is as follows:

There is a default profile set in the Terminal Equipment Controller from the factory.
There will be a 1 minute unoccupied period every night at 11:59 PM with this default configuration.
A) Override an unoccupied period
This menu will appear only when the Terminal Equipment Controller is in unoccupied
mode. Answering yes to this prompt will cause the Terminal Equipment Controller to go
into occupied mode for an amount of time equal to the parameter “TOccTime” (1 to 12
hours).
B) Resume regular scheduling
This menu does not appear in regular operation. It will appear only when the Terminal
Equipment Controller is in Unoccupied override mode.
Answering “Yes” to this question will cause the Terminal Equipment Controller to resume

above example, the Terminal Equipment Controller will control to the unoccupied set
point until 7:00 AM Monday.

* Scheduling events to the same time will cancel the last period and leave the Terminal
Equipment Controller in unoccupied mode
Ex. #2 Residential
* Scheduling consecutive events to the same time will cause the Terminal Equipment
Controller to choose the last event as the time at which it will set its schedule. In the above
example for Saturday, the Terminal Equipment Controller will control to the occupied set
point from 8:00 AM until 11:59 PM. Since it is desired to be in occupied mode throughout
the night, then it is necessary to schedule the first event on Sunday at 12:00 AM. The
Terminal Equipment Controller will force a one minute unoccupied period for a one minute
period (between 11:59 PM and 12:00 AM on Saturday).
