Apex/ electrical/GFI messed up.Help.

You might be on to something with the chiller and if you know one of the bars is at 12 amps, that's getting a bit tight. It's generally recommended to keep draw to 80% of maximum on any given 15 amp circuit for your own safety. Wall mounted GFCIs have improved & the newer ones shouldn't be as prone to nuisance trips, but nothing is foolproof!

Have a look at my earlier post, #17, you may have missed that in the process of writing your most recent reply. The reference manual is very comprehensive, an amazing little piece of kit this Apex. You almost need to hire someone to set it up if you wish to use all of it's capabilities!
