Selecting DHW Heating
Selecting Constant DHW Heating

Selecting a time program (switching times)

Heating system without DHW
recirculation pump
DHW can be enabled / disabled up to
four times per day (four time phases).
Automatic mode is set in the time
program in the factory. That means
DHW heating is enabled in parallel to
the central heating program of the first
available heating circuit, but starts
30 min. earlier (from 05:30 to
22:00 hrs.).
Should you not wish to operate in
automatic mode, you can also set up
individual time programs. You can select
identical time programs for every day or
individual programs for each day.
When setting time programs, bear in
mind that your heating system requires
some time to heat the DHW tank to the
required temperature.
For time programming steps, (see pages
26 and 27). For a sequence of steps to
delete a time phase, (see page 28).

Heating system with DHW recirculation
pump
The DHW recirculation pump transports
hot water through a circuit between the
DHW tank and the draw-off points to
deliver DHW to the taps as quickly as
possible.
DHW heating and the DHW recirculation
pump can be enabled / disabled up to
four times per day (four time phases).
Automatic mode is set in the time
program at the factory. That means
DHW heating and the DHW recirculation
pump are activated in parallel to the
central heating program of the first
available heating circuit, but starts 30
min. earlier (from 05:30 to 22:00 hrs.).
Should you not wish to operate in
automatic mode, you can also set up
individual time programs. You can select
identical time programs for every day or
individual programs for each day.
When setting time programs, bear in
mind that your heating system requires
some time to heat the DHW tank to the
required temperature.
Also, enabling the DHW recirculation
pump is only sensible for those times
when DHW is actually drawn.
For time programming steps, (see pages
26 and 27). For a sequence of steps to
delete a time phase, (see page 28).
