ITC-308 showing heating not cooling for fridge

Building a drying cabinet and plugged in my ITC-308 manual. Fridge cabinet is plugged into the cooling port, turn on and it comes up as heating. First time using and outside temperature 15c and I want to set to 12c temperature. Any ideas why it comes up as heating.

If I can post a photo it shows what it comes up with when first turned on.
