Selecting DHW heating
Selecting constant DHW heating
■ Automatic mode (factory setting)
DHW heating and the DHW circulation pump are enabled in parallel to the central
heating switching times of the first available heating circuit, however they start 30
minutes earlier (from 05:30 to 22:00 h).
■ Individual switching times
You can also set up individual switching times for the following days or parts of the
week if you do not wish to operate in automatic mode:
– The same for every day: Monday to Sunday
– For individual parts of the week: Monday to Friday and Saturday to Sunday
– For every day individually: Monday, Tuesday, etc.
The following explains the setting up of switching times using DHW heating by way
of an example. Proceed in the same fashion to set the switching times for the DHW
circulation pump.
When setting switching times, bear in mind that your heating system requires some
time to heat the DHW cylinder to the required temperature.
For the steps for setting switching times, see page 31.
For a sequence of steps to delete a time phase, see page 32.
