Honeywell electronic thermostat in a store. Heating and cooling losses from a building (or any other container) become greater as the difference in temperature increases. A programmable thermostat allows reduction of these losses by allowing the temperature difference to be reduced at times when the reduced amount of heating or cooling would not be objectionable.
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.
It is an electronic, programmable, and self-learning Wi-Fi-enabled thermostat that optimizes heating and cooling of homes and businesses to conserve energy. [ 2 ] The Google Nest Learning Thermostat is based on a machine learning algorithm: for the first weeks users have to regulate the thermostat in order to provide the reference data set.
Amazon’s Smart Thermostat makes quite a lasting impression. Here’s our full review.
Using a programmable thermostat's setback feature to limit heating or cooling in a temporarily unoccupied building does not waste as much energy as leaving the temperature constant. Using setback saves energy (5–15%) because heat transfer across the surface of the building is roughly proportional to the temperature difference between its ...
A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control.
