Hello guys!
As you may see from my age, I'm pretty new to refrigeration, but I feel that I have a good understanding of the basics

My question is as following:

I have mounted a pump down system with two "freezer rooms" (not sure if "freezer rooms" is the right way to say it) at school. I have only runned it a few times.
I have a Danfoss "EKC 204a" for each room.
I have programmed -22 degrees celsius, as the setpoint. I know that the solenoid valve will close when I start a "defrost". The thing that I'am not 100% sure about is:

Does the solenoid valve close when i reach -22 degrees celsius witch is my setpoint?

Thanks in advance!

Aleksander
