All wiring must comply with local electrical codes and
ordinances. Refer to Fig. 3 through 5 for typical hookups.
A letter code is located near each terminal for
identification.
CAUTION

3. Push excess wire back into the hole.
4. Plug the hole with nonflammable insulation to
prevent drafts from affecting the thermostat.
