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 sys-
tems, refer to page 5. For heat pump systems, see page 6.
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.
M1
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.
