side of Terminal Equipment
Controller (fig. 1).

 Remove wiring terminals from sticker.
 Please read the FCC ID and IC label

installed in the cover upon removal
of cover for the wireless products.

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 Terminal
Equipment Controller.

locking tabs (fig. 2).

2. Pull out cables 6” out from the
wall.

3. Wall surface must be flat and
clean.

4. Insert cable in the central hole

10. Insert each wire according to wiring diagram.

 When replacing an existing Terminal Equipment Controller, label the

wires before removal of the Terminal Equipment Controller.

 Electronic controls are static sensitive devices. Discharge yourself

properly before manipulating and installing the Terminal Equipment
Controller.

 A short circuit or wrong wiring may permanently damage the Terminal

Equipment Controller or the equipment.

 All VT7000 series Terminal Equipment 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, 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.

11. Gently push excess wiring back into hole (fig. 3).

12. Re-Install wiring terminals in their correct locations (fig. 3).

13. Re-install the cover (top side first) and gently push extra wire length back into
the hole in the wall.

14. Install security screw.
