M1 – M3 Display Units
13.2. MB-RL module
Please refer to the chapter 7.3 (Setup) to connect a M-Bus module
The MB-RL module has been designed for retrofitting old Monocote displays equipped
with the optional relay board.
The external M-bus module has the same pinout (SUBD-15) than the relay board of the
Monocote display, so there is no need to change the wiring of the existing installation.
