Y When the LR 1218 is used on bus systems, display of the solar power
from the main control and display panel is NOT possible, even if it sup-
ports a solar power display. The display on the main panel can only be
activated from the SDTBUS. This is only possible using the LRM 1218
solar regulator.
Set 9990219 (LR 1218 with connector material) is required.
