Swing open Room Controller PCB to 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 chart (page 3).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.• 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. 3Schneider Electric | II-SE7600E-A4.EN.12.2015.v2 www.schneider-electric.com/buildings December 2015TERMINAL IDENTIFICATIONTerminal UseTerminal Identiﬁcation Description1 – Cool 2Y2Output for cooling / compressor stage number 2.2 – Cool 1Y1Output for cooling / compressor stage number 1.3 - FanGOutput for the fan.4 - 24 V ~ HotRCPower supply of thermostat, hot side (Delivered from the RTU ).5 - 0 V ~ ComCPower supply of thermostat, common side.

A low-level, always-active back-light 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 scroll-ing is held.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 ena-bled when the outdoor air temperature sensor is connected.• A maximum range status display of 50 °C (122 °F) indicates a shorted sensor. Associated func-tions, 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.Sequence of auto-scroll status displayCLOCKSTATUSSYSTEM MODESCHEDULE STATUSOUTDOOR TEMP.ALARMSMonday12:00 AMSys ModeOffOccupiedOutdoor°C or °FFrost ONSys ModeAutoUnoccupiedSetClockSys ModeCoolOverrideDAS AlrmSys ModeHeatFA AlarmHigh CO2Alarms• 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:Frost ONIndicates that the heating is energized by the low limit frost protection room temperature setpoint 5.6 °C (42 °F).SetClockIndicates that the clock needs to be reset. There has been a power failure which has lasted longer than 6 hours. DAS AlarmIndicates that the discharge air temperature is either too low or too high.FA AlarmIndicates that the Fresh Air level is either too low or too high.High CO2Indicates that the CO2 level value is higher than the Max CO2 parameter value.Sequence of manual-scroll status display:Manual scroll 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.7Schneider Electric | II-SE7600E-A4.EN.12.2015.v2 www.schneider-electric.com/buildings December 2015USER INTERFACEUser Conﬁguring Instructions MenuThe SE76X6E series of Room Controller feature an intuitive, menu-driven, back-lit LCD display that walks users through the conﬁguring steps, mak-ing 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 auto-matically resumes after exiting the user-conﬁguring menu.If the user pauses at any given time during conﬁgur-ing, Auto Help text is displayed to help and guide the user through the usage and conﬁguring of the Room Controller.Example: Press the YES key to change the cooling temperature setpoint. Use the Up/Down Arrow keys to adjust the cooling setpoint.Each of the sections in the menu is accessed and conﬁgured using 5 keys on 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.Local Keypad InterfaceThe 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.Sequence of User MenuOVERRIDERESUMESYSTEM MODE SETTINGSCHEDULE SETTINGCLOCK SETTINGOverrideschd?
