In this installation, two heat-pumps are present, one for the hot water and another one for the heating system. The household also owns photovoltaic panels for local production.
The modifications concern the control of the homing heating systems and hot water system. The system is plugged above the ripple control, 4 smart relays (ZHDR201) are used (1 for the boiler, 3 for the central heating). 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.
