5.5.2 “Automatic” mode with storage tank

When “Automatic” is selected with storage tank, the boiler only produces heat if the storage tank actually

requests heat within the specified storage tank loading time. Outside these times the boiler is in “Standby"

status.

The heating times should be set within the storage tank loading times so that the provision of heat is guaranteed

over the entire heating time.

Note that the heating circuit and DHW tank are only supplied with heat for as long as the storage tank

temperature is sufficient for the demand.

Tip: In systems with a storage tank and solar panels, choose the storage tank loading time so that solar

energy can be used.

In order to ensure that there is sufficient heat at the start of the DHW tank loading time and heating time, we

recommend setting the storage tank charging time to begin before the start of the DHW tank time or heating

time.
