Thermostat

The EcoDisc 51M-5 is the fifth generation of the best-selling thermostat from EcoDisc. Using the latest in thermostat technology, the 51M-5 is able to accurately adjust the temperature of buildings of any size.
The thermostat is an object in The Sims 4: Seasons. It has three settings to choose from, which will either make a building cooler or warmer, or turn the thermostat off. It can be used on both residential lots and community lots.
Setting the thermostat to a temperature opposite to the outside temperature will significantly increase a household's bills, whereas setting it to a temperature that matches the outside temperature will decrease bills, but make Sims uncomfortable and put them at risk of dying from overheating or freezing. Using a thermostat on a community lot has no effect on bills.
Air conditioners and radiators can be set to synchronize with a lot's thermostat. Adjusting a thermostat to make a lot warmer will turn on radiators and turn off air conditioners, whereas adjusting it to make the lot cooler will do the opposite.
==Trivia==
* Setting the temperature to match outside to decrease the bills serves as a trade-off mechanic to save money in exchange for your Sim's comfort. However, this mechanic is extremely unrealistic, as setting thermostat to "off" in real-life will always save you the most money.
