Heating domestic hot water
The RC30 also allows you to heat the DHW in an energy-
conscious manner. With the factory setting, DHW heating begins
automatically 30 minutes before day mode starts the first heating
circuit, and ends when the last circuit switches to night mode (see
Fig. 6).
Outside the times set in the heating program, DHW heating is
switched off, i.e. no DHW is heated in night mode.
The DHW temperature for day mode is factory-set to 60 °C. The
DHW cylinder is loaded once in the morning before the start of
heating and is only reloaded if the DHW temperature falls 5 °C
below the set value (to conserve energy).
