4.3 Selecting the system control parts
Using the system controller (SC) together other than LM ADAPTER allows connecting operation. Some
rules to be observed for this purpose are introduced below.
4.3.1 Master controller and slave controller
When LM ADAPTER is used together with other system controller inside a system under own control, it is
essential to set a slave SC(requiring a DIP-SW change). In this case, set it so that the control range of LM
ADAPTER is included within the control range of the system controller (air conditioner) which is to be the
master SC.

Figure 4-2. System configuration of system controller
(1) In the case when the control range of the LM ADAPTER is covering that of plural system controllers, make
sure to install the Master system controller that covers the LM ADAPTER control range.
(2) In the case when the LM ADAPTER control range is covering the control range of the system controller
partially, install the system controller so that it covers the entire control range of LM ADAPTER.
