Indirect connection to the Control Board ("Daisy-Chain" Type Wiring)
In this type of installation only one control cable directly connects between the System Controller #1 and the Control Board.
The rest of the System Controllers connect to System Controller #1 in a Daisy-Chain connection.
Refer to the connections and controller settings in the figure shown below.

Notes:
• To avoid unstable operation, do not connect more than
4 System Controllers in a daisy-chain connection.
• The response may be poorer in a daisy-chain connec-
tion. To operate multiple System Controllers at the
same time, it is recommended to use a Home Run con-
nection.
• Confirm that the jumper connector (CN13) on the
Control Board is positioned as shown below.
