Group Control
Figure 39, Figure 40, and Figure 41 show examples of typical control configurations. Figure 39 shows one wired remote controller configured
as a Master to control a group of indoor units. Figure 40 shows two wired remote controllers, one configured as a Master and the other as a
Slave. Figure 41 shows a system with indoor units and fresh air units configured as two groups, each with a Master wired controller. Config-
ure the fresh air units as one group and the standard indoor units as another group. Figure 42 shows both a correct and an incorrect control
configuration for this type of mixed unit system.
