WIRING

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
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. 6.

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.
