IntelliZone2 BACnet Components IntelliZone2 BACnet Zoning Board The IntelliZone2 BACnet zoning board is the master control for the system, has much of the programming for operation, provides basic relay logic for the damper operation and serves as a common connection point for the IntelliZone2 XPC Control and the heat pump.
If any damage is noted, the carrier Locate the IntelliZone2 BACnet panel in an indoor area should make the proper notation on the delivery receipt, that has enough space for service personnel to perform acknowledging the damage.

INTELLIZONE2 BACNET INSTALLATION MANUAL Electrical Wiring Wiring Damper Actuators All wiring must comply with local and state codes. Disconnect the power supply before beginning to wire to prevent electrical shock or equipment damage. All wiring should be run back to the control panel. Keep wires a minimum of 12 inches from any high voltage lines.
