Hello guys.

I am an engineer but I've never worked with refrigeration before so I would like your help understanding a few parameters.

I've got a Ranco VT-9 thermostat that from info I found over the internet is specked at

Cold In +3.5°C
Cold Out -26°C
Warm In +3.5°C
Warm Out -11°C

It also says Defrost termination +3.5°C (constant cut in).

I've viewed other posts on this forum and my understanding is that the cold in and cold out relate to the lowest setting on the thermostat (setting 7) and the warm in and warm out relate to the highest setting on the thermostat (setting 1). Is my understanding correct?

Are the parameters mentioned above correct. i.e. I find it strange that the cold in and warm in are the same. I expected that cold in to be much lower than the warm in.

I do not know how the defrosting thing changes the behavior of the thermostat. Can someone explain this to me?

Where is the end of the capillary tube placed in a two door fridge? Is it somewhere between the freezer compartment and the fridge compartment?

Any type of feedback is welcome and appreciated.

Kilini.
