Important: Ensure that the EOL switches are not set to the ON position
for controllers that are not at the end of the bus.
If the zone coordinator is an end-of-line device on the zone controller network, terminate the network by setting the CS EOL switch S1 to ON.
Note: To determine if a device is an end-of-line device, check the number of wires exiting and entering the terminals:
- A single wire indicates that the device is an EOL device.
- If a controller is wired in a daisy-chain configuration, two wires exiting each terminal indicates that the device is not an EOL device.
