InstallatIon
Remove security screw on bottom of Room
Controller cover.
• Open unit by pulling on bottom side
of Room Controller (Fig. 1).
• Remove wiring terminals from sticker.
• Read the FCC ID and IC label in-
stalled in the cover.
Location
1. Should not be installed on 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 Room Controller.
Installation
1. Swing open Room Controller PCB
to left by pressing PCB locking tabs
(Fig. 2).
2. Pull out cables 6” out from wall. En-
sure wall surface must is and clean.
3. Insert cable in central hole of base.
4. Align base and mark location of two
mounting holes on wall ensuring
proper side of base is up.
5. Install anchors in wall.
6. Insert screws in mounting holes on
each side of base (Fig. 2).
7. Gently swing back 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 their correct locations (Fig. 3).

• 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 verication prior to shipping to ensure
proper and reliable operation in the eld. 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, ow 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.
12. Re-install cover (top side rst) and gently push extra wire length back into hole in
wall.
13. Install security screw.

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: Economizer and all analog outputs and inputs use a half bridge
rectier. Reference of the control signal is the common of the
power supply of the Room Controller. (Terminal C).
Note 3: 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 4: The transformer of the unit provides power to the Room Con-
troller and the additional loads that will be wired to the Room
Controller.

Status display
The Room Controller features a two-line, eight-character display. There is a low back-
light 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 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 lighting 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 a 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.
• The priority for the alarms is as follows:

When any of the fan is ON, the FAN LED will illuminate
When heating & reheat is ON, the HEAT LED will illuminate

User conguring instructions menu
The VT76X6E series of controllers feature an intuitive,
menu-driven, back-lit LCD display that walks users
and installers through the conguring steps, making
the conguring 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-conguring menu.
If the user pauses at any given time during conguring, Auto Help text is displayed to
help and guide the user through the usage and conguring of the controller.
Ex.: Press yes key to change cooling temperature setpoint
Use the up or down arrow to adjust cooling setpoint
Local keypad interface
Each of the sections in the menu is accessed and congured using 5 keys on the
Room Controller cover.
The priority for the alarms is as follows:
The YES key is used to conrm 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 heat-
ing 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 conguring the Room Controller.
The up arrow key is used to increase temperature setpoint and to adjust the
desired values when conguring the Room Controller.
