For the longest time, I put off taking a look at my programmable control unit & trying to figure out how to program it! Because of that, it instead functioned as a correct control unit for quite some time, as such, I would manually adjust the temperature whenever I felt the need, in the days, before I left for work in the summer, I would have to adjust the temperature such that the air conditioning would barely be used at all so that I would not be wasting money on cooling a apartment that no 1 was occupying… Then, I would get apartment to a rather warm apartment & manually change the control unit back up to a temperature that I found comfortable.
It was much the same story for the winter. I would essentially turn off the heat while I wasn’t apartment & return to a easily frosty apartment & turn the control unit back up. I would also adjust the temperature in the days to make things generally cooler, because I savor sleeping in cool temperatures. Then, 1 day recently, I got stuck at apartment because of an approaching hurricane, but most if not all companies were closed down for a couple days, including mine, so I figured I would take a great look at the instruction for the programmable control unit that I had left in a closet someplace & try & figure out how the whole thing worked before I potentially lost power while in the hurricane… Well, both of us never lost power while in the hurricane, even though I did find the time to figure the programmable control unit out, & I haven’t looked back since, and now the control unit automatically adjusts itself according to the schedule I have set, so I never come back apartment to an uncomfortable apartment anymore!
