I can't figure out what you're trying to say

  A programmable thermostat has been a basic part of any central heating system in Britain for over 40 years, probably longer. They are essentially timer switches. One from 1980 would have a 24 hour clock face and two or four coloured pegs at the edge, labelled "on" and "off". You slide the pegs to the time you want the heating to turn on and off. If you have four pegs, there's a switch to use only the first pair, second pair, or both. That was easily sufficient to set the heating to be on in the morning, off as everyone goes to work/school, on again in the evening, and off at night. The more modern equivalent has a digital display and badly labelled buttons, and in reality is much more fiddly to use. If these aren't also normal in American houses then I'm shocked at the waste of energy.
