recieve condenser water flow autostart no air in system flow switch staying made thought oil diff to close to press so changed oil filter nothing else showing up had meters on everthing for two minutes any thoughts

[klove]

First thought: If you're down on condenser flow switch, why'd you change the oil filter?

Second thought: Use some punctuation so that we can tell where one thing ends and another begins.

Third thought: Post a complete model number (from your description, I assume this machine has an Optiview panel?).

Fourth thought: Put something in your profile about your experience level and what you do so that we'll know with whom we're speaking.

Fifth thought: Got flow? Switch made? Pump running? What were meters on? Previous issues with machine? Etc., etc., etc.

*Not trying to be ugly here, but look at it from our point of view.

I know if the eprom has been upgraded, one of the new uprgrades allows you to have a input for condenser flow. If it is not jumper out or added, you will get this error.

One line panels had that upgrade available. Input goes back to the DI board on terminal seventy-something. I have to assume that this machine has been running as-is for some time and this error just came up, based on the OP. 'Course, you know what they say...........
