>Ignore may be a tad strong. I am merely asking for hardware that is subject to my control to be within my control.

Which is how they got into this situation. These are industrial refrigeration systems subject to a huge list of variables (how many units, their sizes, and doors hooked up to a refrigeration circuit, open vs closed cases, ambient conditions, hours of store operation, what type of refrigerant, whether heat is going to a cooling tower or air heat exchanger). They use a ton of energy, and percent optimization leads to millions of dollars over a fleet. They are designed to let the user dial in every operating parameter, like defrost.

Compare this to my home fridge where all these parameters are fixed in the firmware because the hardware is 100% identical.

Industrial systems are necessarily different from mass-produced home appliances.
