Components control the thermostat

I have a habit of going to job and forgetting to change the control unit.  It isn’t too terrible when my fiance leaves after me, but usually I am the last a single to head out.  I am supposed to be turning the air conditioner to a higher temperature, so both of us aren’t cooling the house when no a single is there.  In the winter, the control component is to be set actually low, so the heating isn’t being wasted. I think it should be a easy concept, but I just don’t remember.  My mom and Mom always had a programmable control unit. From as far back as I can remember, Mom had the control component programmed to change temperature from right after they leave until right before someone got home.  It was automatic to have the house cooler when you got house in the winter, or warmer in the summer, because of the programmable control unit. The house my fiance and I just obtained, does not have a programmable control unit.  Normally, I would just go out and buy a new control component and my Mom would entirely even install it for me. My fiance works at a house improvement store. You would guess that he would guess to buy a programmable control component while he is actually working.  Why is it not okay for me to reset the control unit, but it is okay for him to forget to buy a new control unit. I don’t understand the logic there. Maybe I should just stop in there while he is actually working and buy the control component that I want. If he sees me buy it, then he can’t yell at me anymore and he’ll understand that it is partly his fault.
