I just got this unit and I was really excited about it. I installed it and everything seems to be working properly, liquid flow and what not, but I can't get the LCD unit to stop beeping. After I power on my system and set the LDC levels it just keeps beeping and then will eventually shut my system down. I called the offices in California and they tell me that this is a common problem. I was assured that they would contact headquartes to see if they can RMA me a new LCD unit but they are not sure that it can be done. So I'm left to sit here with my main system tore apart until I hear back from them. If anyone knows how to fix this I'd really appreciate a reply. Thanks in advance.
