10 BC10 basic controller
Turn the knob to set the maximum heating system
temperature.
Press the "Chimney Sweep"
mode.
WARNING
– Turn the "heating system temperature"
knob to limit the heating system tempera-
ture to the permissible flow temperature for
the floor heating circuit (e. g. 86 – 104 °F =
30 – 40 °C), so pipes will not overheat.
DANGER
The heating system can freeze up if a power
failure occurs or after switching off the power
supply, because manual operation then is no
longer active.
– You must re-activate manual operation
after switching on the system to keep the
heating system operational (especially if
there is a risk of frost).
