The a/c bills at my home were so high last year that I finally put a locking code on the control unit. Luckily for me, the digital programmable control machine that my wonderful friend and I have has a feature where you can put a code in so nobody can change the temperature settings without the code. At first, I did not know that the programmable control machine even had that feature built into it. I suppose that if I had known that there was a code feature then I would have put one in the control machine a long time ago! That is because my adolescents drive me genuinely crazy with the fact that they are constantly lowering as well as raising the temperatures on the control machine whenever they darn well feel like it. I tell them to leave the control machine alone all the time, however sometimes they just won’t listen. They drive me crazy sometimes as well as I know that it’s my own fault for not being harder on them when they were younger! Now, they suppose that they can just do whatever they want all the time as well as it makes me crazy. Anyway, they kept the control machine lowered so much while in the summer time last year that I ended up paying a literal advantage in air conditioning bills last year. I wasn’t about to do that again this year so I read the manual for our control machine as well as I figured out exactly what I needed to do! Now the code is in as well as the adolescents are locked out! They can’t sit it however I’m happier than I have ever been.
