SEM 7.118 firmware can also detect that a LEM03 is connected to it. This allows LEM03 to be used with Slaves Firmware 7.118 and above
The LEM03 need not be connected only to the main Comfort controller.
However LEM03 should only be connected to the LAST SEM. Connecting LEM03 to a lower ID SEM when there is a higher ID SEM will cause the zones on the LEM03 to conflict with the zones of the Higher numbered SEM
