thermostat

A thermostat is a device that automatically regulates the temperature of a room or building. It works by sensing the current temperature and comparing it to a set desired temperature. If the room is too cold or too hot, the thermostat sends a signal to the heating or cooling system, like a furnace or air conditioner, to adjust the temperature accordingly. You can usually set your preferred temperature, and the thermostat ensures that the environment stays comfortable and energy-efficient, saving both energy and costs. There are manual and programmable models, including smart thermostats that can be controlled remotely.
