INSTALLATION
1. Remove security screw on bottom of
Room Controller cover.
2. Open unit by pulling on bottom side of
Room Controller (fig. 1).
3. Remove wiring terminals from sticker.
4. Read FCC ID and IC label installed in
cover.
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 air
discharge grill.
4. Should not be affected by direct sun
radiation.
5. Nothing should restrict vertical air
circulation to Room Controller.
Installation
1. Swing open Room Controller PCB to
left by pressing PCB locking tabs (fig.
2).
2. Pull cables 6” out from wall. Ensure
wall surface is flat and clean.
3. Insert cable in central hole of base.
4. Align base and mark location of two
mounting holes on wall ensuring base
is in proper orientation. Arrow on
base should be facing up.
5. Install anchors in wall.
6. Insert screws in mounting holes on
each side of base (fig. 2).
7. Gently swing back the circuit board
on base and push until tabs lock.
8. Strip each wire 1/4 inch from end.
9. Insert each wire according to wiring
diagram.
10. Gently push excess wiring back into
hole (fig. 3).
11. Re-Install wiring terminals in correct
locations (fig. 3).

3 | 028-0377-03 November 2015
12. Re-install cover (top side first) and gently push extra wire length back into
hole in wall.
13. Install security screw.

When 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 improper 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 or installer or 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.

Main outputs wiring
Wiring notes:
Note 1: If the same power source is used for the heating stages, install jumper across
RC & RH. Maximum current is 2.0 amps.
Note 2: If auxiliary output is used to toggle occupancy of the electronic control card
inside the equipment, configure the relay parameter (Aux cont) to the N.O.
setting. A second relay can be added for additional functionality of the
occupancy output.
Note 3: The analog outputs and inputs use a half bridge rectifier. Reference of the
control signal is the common of the power supply of the Room Controller.
(Terminal C)
Note 4: Electromechanical contacts are to be used with the digital inputs. Electronic
triacs cannot be used as mean of switching for the input. The switched leg to
the input for the input to activate is terminal C (common)
Note 5: The transformer of the unit provides power to the t Room Controller and the
additional loads that will be wired to 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 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
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.

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.
Alarms
•If alarms are detected, they will automatically be displayed at the end of the
status display scroll.
•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.

10 | 028-0377-03 November 2015
•The priority for the alarms is as follows:
Frost ON
Indicates that the heating is energized by the low limit frost protection room
temperature setpoint 5.6 °C (42 °F)
SetClock
Indicates that the clock needs to be reset. There has been a power failure
which has lasted longer than 6 hours
Service
Indicates that there is a service alarm as per one of the configurable digital
input (DI1 or DI2)
Filter
Indicates that the filters are dirty as per one of the configurable digital input
(DI1 or DI2)
Fan lock
Indicates that the heating and cooling action are locked out due to a defective
fan operation
DAS
Alarm
Indicates that the discharge air temperature is either too low or too high.
When any of the fan is ON, the FAN LED will illuminate
When heating is ON, the HEAT LED will illuminate
When cooling is ON, the COOL LED will illuminate

USER INTERFACE
User configuring instructions menu
The VT76X6FX series of controllers feature an intuitive,
menu-driven, back-lit LCD display that walks users and
installers through the configuring steps, making the
configuring process extremely simple. This menu is
typically accessed by the user to set the parameters
such as the clock time set, the schedule time events
and the system mode.
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 controller.
Local keypad interface
The YES key is used to confirm a selection, to move onto the next menu item
and to manually scroll through the displayed information.
The NO key is used when you do not desire a parameter change, and to
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 Room Controller.
The up arrow key is used to increase temperature setpoint and to adjust the
desired values when configuring the Room Controller.
When left unattended for 45 seconds, the display will resume automatic status
display scrolling.
To turn on the back light, press any key on the front panel. The back lit display
will turn off automatically after 45 seconds.
