Location

Subbase Without Remote-Mounted Temperature Sensor

Install the subbase about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 2.

Do not install the subbase 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.

Subbase With Remote-Mounted Temperature Sensor(s)

Install the subbase in an area that is accessible for setting and adjusting the temperature and settings.

Install the remote-mounted sensor(s) about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 2.

Do not mount the sensor(s) 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.

If more than one remote sensor is required, arrange them in a temperature averaging network consisting of two, three, four, five or nine sensors. See Fig. 3 through 7.

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

Subbase Installation

The subbase can be mounted horizontally on the wall or on a 2 in. x 4 in. wiring box.

1. Position and level the subbase (for appearance only).

The thermostat functions properly even when not level.

2. Use a pencil to mark the mounting holes. See Fig. 8.

3. Remove the subbase from the wall and drill two 3/16 inch

holes in the wall (if drywall) as marked. For firmer material such as plaster, drill two 7/32 inch holes.

4. Gently tap anchors (provided) into the drilled holes until

flush with the wall.

5. Position the subbase over the holes, pulling wires

through the wiring opening.

6. Loosely insert the mounting screws into the holes.

7. Tighten mounting screws.

WIRING

All wiring must comply with local electrical codes and ordinances. Follow equipment manufacturer wiring instructions when available. Refer to Fig. 16 through 21 for typical hookups. A letter code is located near each terminal for identification. Refer to Table 4 for terminal designations.

WARNING

Electrical Shock Hazard. Power Supply can cause electrical shock.

Disconnect power supply before beginning installation.

1. Loosen the terminal screws on the back of the

thermostat and connect the system wires. See Fig. 9.

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 prevent

drafts from affecting the thermostat.
