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