5.5.2 Operating modes for DHW

You can set one of the following operating modes for DHW heating:

• automatic operation (switching program). This can be either the switching program for central

heating or a specific DHW program (Æ page 38).

• permanently ON (manual continuous mode). The DHW is permanently maintained at the set

temperature.

• permanently OFF/ECO (manual night mode). You can use to start DHW heating when

needed (“Heating up DHW once”, Æ page 18).

5.5.3 Operating modes for DHW circulation

The DHW circulation pump ensures quick supply of DHW to the draw-off points (if installed). This

is achieved by circulating the DHW once or more per hour through the DHW circulation pump via

a separate DHW circulation line. This interval can be adjusted by your heating contractor in the

Service menu.

You can set one of the following operating modes for DHW circulation:

• automatic operation: DHW circulation starts 30 minutes prior to the first heating circuit being

heated up and stops with the last heating circuit (factory setting). Alternatively, you can set a

separate DHW circulation program (Æ page 38).

• permanently ON: The DHW circulation pump runs constantly at the set interval, regardless of

the heating circuits.

• permanently OFF: The DHW circulation pump is not triggered at the set interval. You can use

to heat up DHW and start DHW circulation when needed.

5.5.4 Operating modes for solar

• automatic operation (default setting)

• permanently OFF (manually switched off)

• permanently ON (constant manual operation). The solar thermal system will be in constant

operation for 30 minutes at maximum pump output. After 30 minutes the solar heating system

automatically switches back into automatic mode.

The operating mode “constant operation” effects a manual control of the solar circuit pump.

However, the solar thermal system will cut out if either the collector array or the cylinder exceeds

their maximum permissible temperatures (collector protection function).

For explanations regarding the settings, see the solar module documentation.
