Wallplate Installation

The thermostat can be mounted horizontally on the wall

or on a 2 in. x 4 in. wiring box. Position wallplate

horizontally on the wall or on a 2 in. x 4 in. wiring box.

1. Position and level the wallplate (for appearance

only). The thermostat will function properly 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 holes in the wall (if drywall) as marked.

For firmer material such as plaster, drill two 7/32

inch holes. Gently tap anchors (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 for typical hookup. A letter

code is located near each terminal for identification.

CAUTION

Disconnect power before wiring to prevent

electrical shock or equipment damage.

1. Loosen the terminal screws on the wallplate and

connect the system wires. See Fig. 4.
