Hi All, first post here so go easy on me, i hope to share my recent ASHP findings and help others! I’ve recently had a LG Therma V installed with a new hot water cylinder with integral buffer tank, all pre plumbed. system works well but is the settings that’s I’m getting into trouble with. for DHW the default setting is 50 degrees. I’ve managed to get into the installer mode and raise this to 55 degrees and raise this in the owner side of the settings. However this defaults back to 50 so never reaches 55 unless I manually push it to 55?? any ideas what I’m doing wrong? TIA
