performed with all connected cycle PCBs and HMI PCB connected. If it is not performed, it will result in operation error.
• When setting the address, check and change other control box PCB address within the chiller. PCB address for replacements is set to 1. If
the control box PCB address is duplicated, the chiller will not operate.
• Control box PCB addresses are set to 1 as factory default.
