Hi, how are you? Sorry for the delay getting to your question. The low pressure error is caused by low charge, metering issues or some type of restriction. There is actually a myriad of things that can cause it. Are you receiving this error during heating operation? Thanks

Hi, sorry for the delay. I was at a family gathering. You need to make sure it is defrosting correctly. When it gives you this error, is there a significant amount of ice or frost on the outdoor coil?
