INSTALLATION

Inspection

• Remove security screw on bottom of Room Controller cover.

• Open unit by pulling on bottom side of Room Controller (Figure-1).

• Remove wiring terminals from sticker.

• Read the FCC ID and IC label installed in the cover.

Location

• Do not install on an outside wall.

• Install away from any direct heat source.

• Do not install near air discharge grill.

• Do not locate in direct sun radiation.

• Nothing should restrict vertical air circulation to Room Controller.

Installation

1. Swing open Room Controller PCB to the left by pressing two PCB
retaining tabs (Figure-2).

2. Pull cables 6" out from wall.
Ensure wall surface is flat and clean.

3. Insert cable into central hole of base.

4. Align base and mark location of two mounting holes on wall ensuring
proper side of base is upward.

5. Install screw anchors in wall.

6. Insert screws in mounting holes on each side of base (Figure-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 in base.

11. Reinstall wiring terminals in correct locations (Figure-3).

12. Reinstall cover (top side first) and gently push any extra wire length back
into hole in wall.

13. Install security screw.

Figure-1 Ope ning the Cover

• If replacing an existing Room Controller, label wires before
removal of Room Controller.

• Electronic controls are static sensitive devices. Discharge
yourself properly before manipulating and installing Room
Controller.

• A short circuit or wrong wiring may permanently damage the
Room Controller or the equipment.

• All SE7000 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) 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.

NETWORK READY

• All Schneider Electric SE7600 series Room Controllers
(TEC) are designed for stand-alone (Network Ready) operation.

• They can be fully integrated into your choice of automation systems using
the available communication adapter options.

• If required, stand-alone (Network Ready) TECs can be field retrofitted with
the following communication adapters:

• VCM7000V5045W wireless Zigbee® communication adapter.

• VCM7600V5045B BACnet® MS-TP® communication adapter.

Wiring Notes

Note 1
If the same power source is used for the heating
stages, install a jumper across terminals RC and RH.
The maximum current is 2.0 amps.

Note 2
If the 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
Economizer output uses a half-bridge rectifier.
Reference of the control signal is the Common
(Terminal C) of the power supply of the Room
Controller.

Note 4
Electromechanical contacts are to be used with the
digital inputs. Electronic triacs cannot be used as a
means of switching for the input. The switched leg
to the input for the input to activate is the Common
(Terminal C).

Note 5
The transformer of the unit provides power to the
Room Controller and the additional loads that will be
wired to the Room Controller.

CONFIGURING / STATUS DISPLAY
INSTRUCTIONS

Status Display

The Room Controller features a two-line, eight­character display. A low-level, always-active back­light can be seen only at night.

Left unattended, the Room Controller shows an
auto scrolling display that indicates the status of the
system. Each item is scrolled one by one with the
back lighting in low level mode. Pressing any key
will cause the back light to increase 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.

Alarms

• If alarms are detected, they will be displayed automatically 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 speeds are ON,
the FAN LED will illuminate.

When heating & reheat is ON, the
HEAT LED will illuminate.

When cooling is ON, the COOL LED
will illuminate.

Outdoor air temperature

• The outdoor air temperature display is only ena­bled when the 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)
indicates an open-circuited sensor or a sensor
not connected. Associated functions, such as
mode lockouts and economizer function are
automatically disabled.

USER INTERFACE

User Configuring Instructions Menu

The SE76X6 series of Room Controller feature an
intuitive, menu-driven, back-lit LCD display that
walks users through the configuring steps, mak­ing the configuring process extremely simple. This
menu is typically accessed by the user to set the
parameters such as temperature and time events,
system mode, fan mode, etc...

It is possible to bring up the user menu at any time
by pressing 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
Room 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. May also be used to
toggle between heating and cooling setpoints.

The MENU key is used to access the Main User Menu or
to exit the menu.

The DOWN ARROW key is used to decrease a temperature
setpoint and to adjust the desired values when configuring the
Room Controller.

The UP ARROW key is used to increase a temperature setpoint
and to adjust the desired values when configuring the Room
Controller.

cover.

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 light will turn off when the Room
Controller is left unattended for 45 seconds.
