,Hello everyone,
currently my delanair system despite being on 85 degrees continues to throw only freezing air leaving the central grille open that is as if it were on maximum cooling; hot water opening valve just changed vacuum circuit working fuses controlled both on the dalanair and in the right and left fuse holders; suddenly then it sends hot air and works correctly and then randomly returns to the aforementioned error. I ask you what fault it may be (relay amplifier or other.
Thank you with all my heart crumb

Sounds like the amplifier is failing. Rather common. A bit expensive as guesses go....but a decent chance that it'll fix the problem

Cheers

You may want to reach out to Gary Crosby at JagAire... He knows the systems like the back of his hand, and can help troubleshoot the issue, as well as offer replacement parts where needed.
He has a new replacement Amp if it is the problem and it's been proven to fix a bunch of problems...
Cheers,

I second David's recommendation above!
I have dealt with Jag-Aire/ Gary Crosby more than once and have been Very pleased each time.
He even has diagnostic procedures listed on his web page to help you figure it all out.
In fact, Gary's expertise is why Nix's climate control works so well.

Thank you very much; I contacted jag aire.... but I am not sure that ampli is broken
we hope that from the symptoms I have described someone can help me

You might try and back flow the heater matrix, I know mine is obstructed and I need to carry this out as well. I've heard good stories of success clearing blocked heater matrices.
I have both the Jagair amp and a refurbished servo (also from Jagair) and have eliminated both, only thing left is the matrix
