WIRING
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.
The HZ322 offers many innovations for wire management and organization: wires can be run
behind the panel, through wire channels on its sides, and must be attached to a wiring anchor
with a cable tie.
