In this second version, the modification concerns the central heating systems.
Instead of heat-pump, the central system is an electrical system that heats water which will heat the household. Therefore, the system is also plugged above the ripple control, but 3 smart relays (ZHDR201) are needed (1 for the boiler, 2 for the central heating). The modifications to monitor the consumption and the production of the photovoltaic panels is also performed with a prosumer meter (SMMZB-310).
Finally, two temperature meters (ZHOT101) are used, one to monitor the outside temperature and one to monitor the inside temperature.
