LG Therma V R290 Monobloc (SG Ready)
Modbus connection to LG Therma V heat pump. Uses SG Ready energy states for intelligent control. Set the indoor unit in the installer settings > "Connectivity" > "Energy state" > "ESS use type" > to "Modbus". Since the internal power measurement shows too high values, an external power measurement is suggested. Factory setting Modbus (HEX) = 21 (33). Modbus registers can be found within the installation manual (address without the leading number and -1). Information on the energy state can be found within the installation manual. Energy states 6 and 7 can be adapted at the indoor unit in the installer settings > "Connectivity" > "Energy state" >"Energy state definition". If the internal power measurement does not work (not all models support this register), please set energy metering to "false".
