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.
