3 Connect LON bus cable to LON module (connections CLA and CLB).
4 Controller ON:
The module starts / initialization begins.
Communication with the controller and LON bus is active as soon as
the two LEDs "BSP" and "BUS" are steady green.
Caution: HMI must be reset a second time to update; prior to parame-
