MERCURY NOTICE

If this control is replacing a control that contains mercury in a sealed tube, do not place your old control in the trash. Dispose of properly.

Contact your local waste management authority for instructions regarding recycling and the proper disposal of the old control.

4. After completing installation, use these instructions

to check out the product operation.

Location

Install the thermostat about 1.5m (5 ft) above the floor in an area with good air circulation at average temperature. See Fig. 1.

Do not install the thermostat where it can be affected by: — drafts, or dead spots behind doors and in corners. — hot or cold air from ducts. — radiant heat from sun or appliances. — concealed pipes and chimneys. — unheated (uncooled) areas such as an outside wall

behind the thermostat.

INSTALLATION

When Installing this Product...

1. Read these instructions carefully. Failure to follow

the instructions can damage the product or cause a hazardous condition.

2. Check the ratings given in the instructions and on

the product to make sure the product is suitable for your application.

3. Installer must be a trained, experienced service

technician.

Wallplate Installation

The thermostat can be mounted horizontally on the wall or on a 2 in. x 4 in. (50.8 mm x 101.6 mm) wiring box. Position wallplate horizontally on the wall or on a 2 in. x 4 in. (50.8 mm x 101.6 mm) wiring box.

1. Position and level the wallplate (for appearance

only). The thermostat functions correctly even when not level.

2. Use a pencil to mark the mounting holes.

See Fig. 2.

3. Remove the wallplate from the wall and drill two

3/16 inch (76 mm holes) in the wall (if drywall) as marked. For firmer material such as plaster, drill two 7/32 inch (5.56 mm) holes. Gently tap anchors

[1.5 METERS]

(provided) into the drilled holes until flush with the wall.

4. Position the wallplate over the holes, pulling wires

through the wiring opening.

5. Loosely insert the mounting screws into the holes.

6. Tighten mounting screws.

WIRING

All wiring must comply with local electrical codes and ordinances. Refer to Fig. 3 and 4 for typical hookup. A letter code is located near each terminal for identification.

CAUTION

Electrical Hazard. Can cause electrical shock or equipment damage.

Disconnect power before wiring.

1. Loosen the terminal screws on the wallplate and

connect the system wires. See Fig. 5.

IMPORTANT

Use 18 gauge, color-coded thermostat cable for proper wiring.

2. Securely tighten each terminal screw.

3. Push excess wire back into the hole.

4. Plug the hole with nonflammable insulation to pre-

vent drafts from affecting the thermostat.

The two OC terminals can be wired to the TZ-4 panel for remote operation of the Zone-A-Lone feature during the Leave and Sleep periods. See Table 9 and the TZ-4 Installation Instructions, form 68-0259, for more information.
