Thermostat

A thermostat is a component of a control system which senses the temperature of a system so that the system's temperature is maintained near a desired setpoint. The thermostat does this by switching heating or cooling devices on or off, or regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. The name is derived from the Greek words thermos "hot" and statos "a standing".

Home automation

Home automation is the residential extension of "building automation". It is automation of the home, housework or household activity. Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, and other systems, to provide improved convenience, comfort, energy efficiency and security.

Programmable thermostat

A programmable thermostat is a thermostat which is designed to adjust the temperature according to a series of programmed settings that take effect at different times of the day. Programmable thermostats may also be called setback thermostats or clock thermostats.

Wax thermostatic element

The wax thermostatic element was invented in 1936 by Sergius Vernet(1899-1968) . The principal application of the wax element technology is for the production of automotive thermostats. The first applications of this technology in the plumbing and heating industries were in Sweden (1970) and in Switzerland (1971). Wax thermostatic elements permit the transforming of thermal energy into mechanical energy.

Programmable communicating thermostat

The term programmable communicating thermostat (PCT) is used by the California Energy Commission to describe programmable thermostats that can receive information wirelessly. The first version of the PCT introduced in the 2008 building standards proceeding also required that PCTs allow temperature control during emergency events to avoid blackouts. This feature was removed after public input indicated a strong fear of the non-overrideable "big brother" feel of this feature.

Temperature control
Berendsen thermostat

The Berendsen thermostat is an algorithm to re-scale the velocities of particles in molecular dynamics simulations to control the simulation temperature.

Molecular dynamics
Nosé–Hoover thermostat

The Nosé–Hoover thermostat is a deterministic method used in molecular dynamics to keep the temperature around an average. It was originally introduced by Nosé and developed further by Hoover. The heat bath is made into an integral part of the system by adding an artificial variable associated with an artificial mass.
