Fig. 1. Typical location of thermostat.
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
(provided) into drilled holes until flush with 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 6 for typical hookup. A
letter code is located near each terminal for identification.
CAUTION
Electrical Hazard.
Can cause electric shock or equipment
damage.
Disconnect power before wiring.
1. Loosen the terminal screws on the wallplate and
connect the system wires. See Fig. 7.
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.
