Description
The LG PMBUSB00A Modbus Gateway enables communication with Air Conditioners, Ventilators / DX Vetilators and HydroKit & AWHP heat pumps.
As the Gateway supports up to 255 units, the indoor units have to be addressed by the LG technician. In this template we can see predefined registers for the LG AC unit with address 0. We have to recalculate the addresses for units >0. We can easily recalculate the correct addresses in the attached excel table.
