From Comfort Firmware 7.117, Comfort will detect if the LEM03 is connected to it see http://www.comfortforums.com/forum79/4673.html
The checkbox in Comfigurator > Configuration > Modules and Settings > LEM03 (24 Zone) can be ignored. After reading from Comfort this setting will show if LEM03 is connected or not, so it will be a Read Field. Writing into the LEM03 checkbox has no effect. The LEM03 state can only be seen after reading from Comfort
