Ämne: F2040-8 showing strange temperatures

[Joseph Azadehdel]

Hey sorry for English I am still learning.
My f2040-8 is showing the return temperate as higher than the condenser out temperature. Sometimes up to 10 degrees. Does anyone know if this is correct? And if not why it would be happening?

Thanks!

During defrost condenser out temperature is supposed to be lower than return. Defrost duration is 2-7 minutes.
If the condenser out is lower than return temperature during heating, something is wrong.

I had the same problem. The sensor for in / out temp inside the F2040 (BT12/BT3) were switched at the motherboard. The installer fixed this.
