2-18 Installation and Wiring
Set the Zone Controller Address Switch using the addressing instructions in
Figure 2-13.
Caution: Incorrect addressing is the number one cause of communication prob-
lems. Check the addressing carefully. Remember, the Zone Controller
only reads the switch during a power-up. If the address switch is
changed, the unit
must be turned OFF and then ON before the new
setting will be recognized.
Note: Ignore any markings or numbers on the switch. Use this chart!
