The thesis is based on upgrading the heating system. In the system, a controller and minicomputer with a graphical user interface have been implemented to improve and simplify the operation of heating and hot water. Motor drives for switching valves have also been added to the system. The switch between the central stove on pellets and the heat pump is now much more convenient, as the switch can be performed on the graphical user interface rather than manually, as was the case before the renovation. In the heating system, relay circuits have been added, so that certain devices can be switched on via the graphical
interface, while others can be switched on automatically. In the system upgrade, five digital
thermometers have also been introduced, which enable better control of the system.
The program is implemented in the controller, which is subject to the conditions on the
graphical user interface. For safety reasons, heating can be operated via the old system, that
is, with the use of thermostats on devices and manual shifting of the valves.
