10.3.2 SETTING THE MAXIMUM CH FLOW
TEMPERATURE
B
Set the upper CH flow temperature limit for heating
mode (
Æ
table 17) using the "Maximum CH flow
temperature" dial (
Æ
fig. 94, [8]).
This limit value does not apply to DHW mode.
10.3.3 SETTING THE PUMP RUN-OVER TIME
Set the pump run-over time to 24 hours if the heating
system is controlled depending on room temperature,
and there is a risk of parts of the heating system not
controlled by the room controller freezing (e.g. radiators
in the garage).
B
Set the pump run-over time according to the
"Settings" menu (
Æ
table 13, page 45).
10.3.4 SWITCHING DHW MODE ON/OFF
B
Set the DHW mode according to the "Settings" menu
(

required temperature of the hot water in the hot
water cylinder (
Æ
table 18).

WARNING:
Damage to the installation due
to overheating the floor slab when using an
underfloor heating system.
The setting at the BC10 cannot be adjusted
via the menu but must instead be set via the
"Maximum CH flow temperature" dial
(
Æ
fig. 94, [8]).
B
Limit the maximum CH flow temperature
in the "Settings" menu (in most cases
45 °C).
B
Observe that the underfloor heating
system must be equipped with a safety
limiter, e.g. via the external switching
contact (

The temperature is set permanently on
the BC10 and cannot be changed with a
room controller (e. g. RC35).
Aut
The temperature is determined
automatically on the basis of the heating
curve. If no room controller is connected,
90 °C is the maximum CH (boiler) flow
temperature.
