Have been running the CRTT for a year. Recently had the main light go red and a beep start. This apparently is due to the controller not getting a flow reading. This can be caused by either a) the flow sensor failing or b) the feed pump failing or c) feed line clog.
My cause was the feed pump. Deltec sent a replacement and it’s back in operation.
If I had to do this over I would verify if the pump works my pressing the mode button for 5 seconds. This will cause it to pump. That should help point you in the right direction.

Time has passed and started getting this alarm again. Deltec sent me some spare filters and check valves (thanks!) which has helped keep things going well. Now the paddle wheel flow sensor got gummed up. Disassembled and cleaned and seems to work fine again.
