Figure 2-14:
Zone Controller Wiring & Addressing
Set the Zone Controller Address Switch following the following addressing
instructions.
Caution: Incorrect addressing is the number one cause of communication
problems. 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 then ON before the
new setting will be recognized.
Note:
Ignore any markings or numbers on the switch. Use this chart!
