I have a habit of going to job and forgetting to change the control unit. It isn’t too bad when our hubby leaves after me, but usually I am the last one to head out. I am supposed to be turning the air conditioning to a higher temperature, so we aren’t cooling the home when no one is there. In the Winter, the control device is to be set absolutely low, so the heating isn’t being wasted. I guess it should be a straightforward concept, even though I just don’t remember. My mom and dad consistently had a programmable control unit. From as far back as I can remember, dad had the control device programmed to change temperature from right after they leave until right before someone got home. It was automatic to have the home cooler when you got home in the Winter, or warmer in the summer season, because of the programmable control unit. The home our hubby and I just bought, does not have a programmable control unit. Normally, I would just go out and buy a current control device and our dad would really even install it for me. My hubby works at a home improvement store. You would think that he would think to buy a programmable control device while he is finally working. Why is it not okay for myself and others to reset the control unit, but it is okay for him to forget to buy a current control unit. I don’t understand the logic there. Maybe I should just stop in there while he is finally working and buy the control device that I want. If he sees myself and others buy it, then he can’t yell at myself and others anymore and he’ll understand that it is partly his fault.
