The eBUS 2-wire interface is an asynchronous serial port with active-low voltage that exchanges 8-bit bytes with start and (single) stop bits (no parity bit), at a symbol rate of 2400 baud, and can be implemented with a standard UART plus a voltage converter.
OpenTherm was founded in 1996 because multiple manufacturers needed a simple-to-use communicating system between room controller and boiler. It had to run, like the existing controllers, over the existing two wires, not polarity sensitive, without the use of batteries.
The history of the Vaillant Group dates back to 1874, when Johann Vaillant set up a master fitter's business. In 1894 Johann Vaillant patented a new "closed-system" gas-fired bathroom boiler. [3] This was the first device that made it possible to heat water hygienically, without contaminating it with combustion gases.
The control action is the switching on/off of the boiler, but the controlled variable should be the building temperature, but is not because this is open-loop control of the boiler, which does not give closed-loop control of the temperature. In closed loop control, the control action from the controller is dependent on the process output.

A boiler is a pressure vessel and industrial boilers are constructed, operated and inspected in accordance with local regulations to reduce the risk of explosion. For example, permanently installed pressure relief valves will operate if a control malfunction results in excessive pressure in the boiler.
