Thermostats operate in a way so as to control (through their extensions) temperature about a selected setpoint. Some are fixed and some can have the setpoints selected. There must be some "sensor" in the device that will react to changes in temperature. The response of the "sensor" is used to direct intervention to affect control of the temperature. Wikipedia has a good post on the different types of thermostat and how they work. A link is provided.

The negative feedback system. It works much the way a thermostat works. When the temperature in a room drops below a set level, the thermostat signals the furnace to turn on.

It will continue to stay off until the thermostat signals that the temp has dropped again.
