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.
