– Sensor on FB10: The temperature sensor
fitted inside the remote control FB 10 is
used.
Menu: Heating parameters > Room temperature
offset
B Set the constant raising of the required room
temperature, e.g. to correct deviations due to
the system.
Menu: Heating parameters > Heating off until
lower level reached
B Select the cool-down phase:
– No: Heating mode corresponds to the
heating curve.
– Yes: Heating operation according to the
heating curve, however no heating
operation during the cool-down phase until
the current room temperature (e.g.
Comfort = 21.0 °C) reaches the required
room temperature of the next operating
mode down for the first time (e.g.
Economy with 15.0 °C). Afterwards,
heating commences in accordance with
the next operating mode down (e.g
Economy with 15.0 °C).
Menu: Heating parameters > Heating off at
outside temperature
B Set the outside temperature at which the
heating system should switch off:
– 10 °C ... 25 °C: Outside temperature at
which the heating system switches off.
– 99 °C: Function switched off, i.e. the
heating system can switch on at any
outside temperature.
Menu: Heating parameters > Freezing risk at
outside temperature
• If the outside temperature exceeds the set
frost threshold temperature by 1 K ( °C) and
there is no heat demand, then the heating
circuit pump switches off.
• If the outside temperature does not reach the
frost threshold temperature, then the heating
circuit pump switches on (system frost
protection).
B Set the frost threshold temperature at which
the heating system should switch on.
NOTICE: Heating water pipework
may freeze if the frost threshold is
set too low and there are long
periods of outside temperatures
below 0 °C.
B Factory setting of the frost
threshold (3 °C) must only be
adjusted to the system by a
heating contractor.
B Don’t set the frost threshold too
low.
Damage caused by the frost
threshold being set too low is
not covered by the warranty.
