Features of selection of controllers for boilers and heating networks.

The paper presents solutions for selecting controllers for boiler houses and heating networks. It is shown that controllers are highly specialized in performing functions specific to the requirements for heating networks. Specialization can be seen at all levels - from input-output characteristics, microprocessor characteristics and data visualization and alarm signals on the computer panel. Among the selected functions, the functions of ensuring the operation of controllers according to the seasons "Winter - Summer", as well as the choice of modes in order to simplify control tasks, stand out. An important requirement for network controllers is low cost and the ability to operate the controller by a low-skilled user. Using the example of Vitotronic and Segnetics controllers, the implementation of the requirements for the selection of controllers for boiler houses and heating networks is demonstrated.
