WIRING
CAUTION: Voltage Hazard.
Can cause electrical shock or equipment damage. Disconnect power before beginning installation. Wire entire panel before applying transformer power.
Follow these steps for wiring all systems. However, wiring will vary depending on equipment. For conventional systems, see page 5. For heat pump systems, see pages 6 and 7. For dual fuel systems, see pages 8 and 9.
Wiring must comply with applicable codes, ordinances, and regulations. Use the following wiring diagrams to wire the zone panel to the thermostats and dampers.
Install thermostats using instructions provided with thermostats.
3If using wired thermostats, connect thermostat to zone panel. To connect wire to the panel, strip approximately 1/4 in. of insulation and push wire into terminal. To release wire, press the button on top of the terminal.
