Low discharge issue

[frank]

If it is working and achieving temps, why the query on one aspect, which seems to be based on your expectations.
If it wasn't achieving temps then I could understand your concerns.
It reminds me of an instance when R407C first came out and I went to service a heat pump a/c. Found the outdoor coil very thick in frost/ice and thought that the defrost was faulty. Speaking with Tech support, he said "are the indoor temps ok?" which they were, then there is not a problem and it will defrost when necessary, He was spot on.
As always, it would be great to have an insight into the control strategy so we could understand what should be happening but each manufacturer keeps such information close to their chest, so to speak

I haven't ever seen discharge temps this low before and worried about compromising the lifespan or performance. R32 is known for its high discharge temps so having such a low one is what's concerning me.
