QHY294M can't reach anounced temp delta
« on: January 31, 2021, 05:42:00 AM »
My new qhy294m cannot cool down less than 27 degrees below ambient. Is there way to improve temperature delta at least to -30? My old qhy294c can make -37 delta.
Thank you.

Yuki

You can try to capture a 5 seconds frame, maybe the cooling effect will be better.

If you are not satisfied with the cooling effect, we can send you the replacement.

Best Regards

Nothing helps. 25 degree delta is maximum.
Should I contact local seller for replacement or you will send it directly to me?
