Correct work without your participation
Modern house is full of various engineering systems. Among them there are boiler room, swimming pool, ventilation and conditioning, water supply electricity supply, etc. All this diversity must work, work and work correctly 24 hours a day 365 days a year .
It is easy to provide that. It will be enough to employ an engineer who knows about all the systems, can watch over the sensors’ data, fix the parameters of controllers.
However, there may be another variant. Automatics is able to look after temperature and pressure, pollution and consumption, voltage and current strength, other necessary parameters.
And then, one may get warnings of breakdowns and necessity of maintenance. Any novice will be able to change the work modes (within possible limits, of course!).
