Identify the main parts of control heating system

     1- Boiler:- heats water in a closed-water system

     2- Cylinder: - it’s a huge tank that carries the water supply.

     3- Pumps: - circulates the water in the closed system, it      also reduces the cooling down of the hot water.

     4- Radiator: - wall-mounted panels through which the    heated water passes in order to release heat into rooms.

Recognize the role of ICT in this system.

The role of ICT in this system use of varies devices started from the sensors. The sensors picks up and senses the analog signals in the water, and here comes the use of the next devise which is ADC analog digital converter were the analog signals are being converted to digits so that a computer can pick up these digital codes and sees the requirement of the user, is it the temperature he asks or not? Than it changes the require changes and is sent to the DAN were the digits sent are being converted to analog signals and received by the accumulator which then gives orders to the system.
