Remarks of Siemens This section outlines how Siemens interprets the functions and processing functions according to EN 15232:2012. 3. The heating heat generation operated over the course of a year at a higher load level and effectiveness by reducing the operating time and uses less energy accordingly. 4. The electric heating assumes storage charge output the heating period. The charge time enable should be set to a timeframe where no peak loads occur and lower electricity rates are available. 34
AUTOMATIC CONTROL 2 DOMESTIC HOT WATER SUPPLY CONTROL BT Reason for energy savings 2.3 Control of DHW storage temperature, varying seasonally: with heat generation or integrated electric heating 0 Manual selected control with charging pump on/off or electric heating 1 Automatic selected control with charging pump on/off or electric heating and charging time release 2 Automatic selected control with charging pump on/off or electric heating, charging time release and demand-oriented supply or multi-sensor storage management 3 Automatic selected control with heat generation, demandoriented supply and return temperature control or electric heating, charging time release and multi-sensor storage management Control is effected via thermostat. The generator must be preselected: 3 Generator is shut down automatically during nonheating periods and electric heating is released. Just the opposite during heating periods. This increase the level of use for the heat generator. If the DHW temperature drops below a certain reduced level, recharging takes place even without a time-based release. 4 Demand-controlled supply temperature reduces heat losses in generation and distribution. The supply temperature can be matched to the DHW storage tank temperature and increased as needed. Spreading the load over time (e.g. heating circuits) lowers the maximum output for generation: Generation can be operated in an optimum part load range and efficiency. Multi sensors allow for dividing the DHW storage tank into various zones, ensuring better adaptation to usage. This reduces heat losses in the storage tank. Lower return temperatures can be achieved through a reduction in the supply volume. This is required for condensing boilers, heat pumps, and district heating substations and saves energy. 35
