PV and prosumer heating systems control

In this installation, the heat-pump managed the hot water and the central heating system. This implies that the cut of the controller has to take care of the two temperatures, the inside temperature and the temperature of the hot water. The system uses a modified smart relay (ZHDR201) to control the heating systems. The modifications also concern the monitoring of the consumption and the production of the photovoltaic panels. A prosumer meter (SMMZB-310) is added for this purpose.
Finally, two temperature meters (ZHOT101) are used, one to monitor the outside temperature and one to monitor the inside temperature.
