Operating modes

A control system is developed to automatically operate valves and pumps in order to follow the defined strategy either for summer or winter operating modes. The unit is controlled according to the heat demand for space heating or cooling demands and domestic hot water as well. Priority is given to space conditioning. Fig. 3 shows the Hydraulic scheme adopted.
