7.15 Setting the operating mode for DHW circulation
The DHW circulation pump provides an almost instantaneous supply of DHW
to
the draw-off points. For this, the DHW is circulated by a separate DHW
circulation pump twice per hour for three minutes. Your heating contractor
can
match this interval to requirements at the service level.
You can modify the operating mode of DHW circulation as follows:
z Open flap.
Hold down "Heating circ." and select "DHW circulat." with the rotary selector.
Release "Heating circuit".
The permanent display will then appear again.
Select one of the following operating modes for the DHW circulation pump:
– "Constant operat."
The DHW circulation pump will operate at the set interval, i.e. independently
of the heating circuits.
Press "Day mode" to select constant operation. After approximately three
seconds, the
permanent display will appear again.
– "Automatic"
30 minutes before the first heating circuit is started, the DHW circulation
pump starts to run at the set interval, and stops when the last heating circuit
is switched off (factory setting). Alternatively, you can enter your own DHW
circulation pump program (Æ
Chapter 8.4).
Press "Automatic" to select automatic mode. After approximately three seconds,
the
permanent display will appear again.
– "DHW circulation OFF"
The DHW circulation pump will not be controlled. Pressing "DHW" switches
the DHW circulation pump on for the duration of heating DHW once.
Press "Night mode" to switch off DHW circulation. After approximately three
seconds, the permanent display will appear again.
