Rotenso Control Series Installation And User Manual page 61

For some units, one wired controller can support multiple units (a maximum of 16 units).
In this case, the wired controller and unit need to be connected to the HA and HB ports at
the same time. In group control, there will be no error displayed on the wired controller.
