Fake thermostats which exist solely to give the occupants of office buildings an illusion of control are an entire product category. If I were to replace your thermostat with one without your knowledge, you would be just as happy turning it up and down all day.

Can you feel the difference between 73F and 75F? No, you can’t, don’t lie.
As someone who uses their thermostat and regularly switches between 72 and 75, yes. Yes I can.
