I got my first bills and I started seasons on my game in late fall I turned on my thermostat to warmer costs more and my bill was $26,000!! haha (note to self set therm at cooler cost less!!)
I´ve made a test today after my family had a bill over 90.000, before it was 9.600. One week without thermostat in winter and the bill was back to normal. As said above the thermostat increases bills by 25% on warm, but what I miss is the time factor. There must be a difference if the thermostat is all day on or only 1 hour per day, how is this calculated?
