Switching times

Heating system without DHW circulation pump
Note
The control unit is adjusted so that the setting for DHW heating applies to all heating
circuits. If you want to make changes, contact your local heating contractor.
■ DHW heating can be enabled/disabled up to 4 times per day (four time phases).
■ Automatic mode (factory setting)
DHW heating is enabled in parallel to the central heating switching times of the
first available heating circuit, but starts 30 min 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.
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.
Heating system with DHW circulation pump
Note
The control unit is adjusted so that the setting for DHW heating applies to all heating
circuits. If you want to make changes, contact your local heating contractor.
■ The DHW circulation pump transports hot water through a circuit between the DHW
cylinder and the draw-off points to deliver DHW to the taps as quickly as possible.
■ DHW heating and the DHW circulation pump can be enabled/disabled up to 4 times
per day (4 time phases).
■ Also, enabling the DHW circulation pump is only adviseable for those times when
DHW is actually drawn.
