5.4.3 Setup and configuration – DHW tank
▪ For large DHW consumptions, you can heat up the DHW tank
several times during the day.
▪ To heat up the DHW tank to the desired DHW tank temperature,
you can use the following energy sources:
▪ Thermodynamic cycle of the heat pump
▪ Electrical booster heater
▪ For more information about:
▪ Optimizing the energy consumption for producing domestic hot
water, see "8 Configuration" on
▪ Connecting the electrical wiring of the domestic hot water tank
to control box EKCB07CAV3, see the installation manual of the
