Ok got the newest firm ware installed and got the Apex running on it. I tried to explain several times to neptune that I believe there's a serious programing flaw.The controler has clipped or froze eight times in the last three days. What I find strange and why I believe there is an issue with the controlers base program is everytime the unit reads the same 16 F on the temp and 2.6 Ph. I find this to be more then a freak situation regardless of the conversation I had with the rep I spoke too. Not the most impressive trouble shooter and seamed very confused during most of the conversation other then he was sure that it had nothing to do with the programing. FYI-- I did change the temp probe and the Ph probe with new ones on Sunday.Hopefully this new firm ware will correct the issue.I will keep ya posted !
