I just received my ITC-308. When I plug it in I get “Hd” in the top window and “2.0c” in the bottom window. If I press SET for more than 3 seconds, nothing happens. Up and Down arrows keys do nothing.
When I do step 3, the controller goes into heating mode and shows the temperatures in Celsius. Again, none of the buttons do anything.
When I then unplug it and plug it back in, it goes back to showing "Hd” in the top window and “2.0c” in the bottom window. None of the buttons respond to short or long presses.
