The “set DHW” rotary selector [1] enables you to specify
the required DHW temperature in the DHW cylinder.

DHW is always heated at the maximum
permissible boiler water temperature.
Explanation
0
No supply to radiators (exclusively DHW heating).
Eco
1)
1) This function is optimised for appliances with integral DHW
heating (combi boilers, e.g. GB132T). If a programming unit is
installed (otherwise direct adjustment at the BC10), we
recommend the “Aut” setting in conjunction with other boilers.

2)
, DHW temperature 60 °C
If the temperature has dropped significantly, DHW is
first heated to 60 °C again. This reduces the number
of burner starts and saves energy. However, the
water may be somewhat cooler in the first few
moments.
2) The heating program (time switch) of the programming unit
remains enabled, consequently no DHW is produced during
night operation.
30 – 60
The temperature is set at the BC10 and can then no
longer be adjusted with the programming unit.
Aut
The temperature is set at the programming unit
(e.g. RC3x).
60 °C is set as the DHW temperature if no
programming unit is connected.

Settings at the “set DHW” rotary selector
The LED below the rotary selector illuminates
whilst the DHW in the DHW cylinder is being
heated to the preselected set temperature.
Status
Explanation
ON
Burner operational.
Boiler water is heated.

required temperature level or
there is no heat demand.
