I do think zone control is quite simple

My partner and I watched my sister Carrie’s hamster when she was on her honeymoon. The babysitting did not go well for the hamster or me. I felt saddened by it always being in a cage and running on it’s wheel. It has a little ball you can actually put it in in order that it can run around your property. I figured what was the harm, merely did not use the softball and had the hamster get loose. The hamster was like a mouse, I let it right out of the cage and it ran away. I lost the hamster and then found that it snuck out into my ductwork. How did it get into my air ducts? I have to have had a leak inside the ductwork somewhere for the critter to get in. The hamster would explain why my HVAC ducts all night long kept me awake. I also was constantly reminded that I can’t easily get the hamster straight from the ductwork myself. I actually had to call a HVAC contractor to obtain the hamster out. The pest control people don’t include the ductwork tools or the training to not ruin my HVAC ducts. So I had a HVAC professional make use of a giant scrub brush to push the hamster to the open air vent. Then I was able to get the hamster back. I naturally got charged for this service and I had a gross hamster now.I did  not tell Carrie about some of this of course. How difficult would that be? I literally lost her hamster in my ductwork and had to pay some guy to get it out.
