Hi, I am hoping someone can help me!
Last year I installed 4 3phase L.g cassettes in a function room. From the word go these have been a problem. Within 2 months these sytems intermitently trip on the hard wired remote. CH03 flashes, this is a comunication error between remote and indoor unit. I got in touch with L.g and they told me to make sure I installed the remote cable away from any other electrical cable, incase of interferance. I changed the cable for specail data cable used for that purpose. but the symptoms still occur. CH03 falsh on different remotes. 1 day on 1 remote few days later on another. But ! now CH01 is now flashing. Which is indoor unit thermistor problam. Can anyone help! PLEASE! have not got the model numbers to hand, but they are 12kw heat pump sytems. When they operate they are perfect. The customer has also told me that 1 remote sometimes goes blank, and he has to switch it back on on the remote. Hope to hear some answers. Thanks!
