your talking about a company that in a mall store, never fixed its ac, and or left the heat on when it was 90 out becuse it was not some date on a calender...people walked in and left in like 4 min becuse of it, for months, evry year over and over....use to have to wear shorts just to not die at work ....and I worked at one of our "good" stores.
Could it be that the thermostat was controlled by someone in another town?
For some reason, centrally controlled institutions seem to be afraid to allow the local people to control their own temperature. Our school district had them controlled by a computer in Sacramento, 150 miles away. Their excuse was that some people forgot to turn them off at night.
Yes, that was long after the invention of the programmable thermostat.
