TIP
The value can be increased if you have, for ex-
ample, a cellar that you always want to heat,
even in summer.
You may also need to increase the value in
"stop heating" menu 4.9.2 "auto mode set-
ting".
Menu 1.9.4 - room sensor settings
factor system
Setting range: 0.0 - 6.0
Default value: 2.0
Room sensors to control the room temperature can be
activated here.
Here you can set a factor that determines how much
the supply temperature is to be affected by the differ-
ence between the desired room temperature and the
actual room temperature. A higher value gives a
greater change of the heating curve's set offset.
If several climate systems are installed the above set-
tings can be made for the relevant systems.
Menu 1.9.5 - cooling settings (accessory re-
quired)

You can use F1245 to cool the house during hot periods
of the year.
min. temp. cooling flow
Set the minimum temperature on the supply temper-
ature to the climate system during cooling operation.
This means that F1245 never calculates a temperature
lower than that set here.
cooling flow temp. at +20°C
Set the desired temperature on the flow temperature
to the climate system during cooling operation when
the outdoor temperature is +20 °C. F1245 then at-
tempts to get as close to the set temperature as pos-
sible.
cooling flow temp. at +40°C
Set the desired temperature on the flow temperature
to the climate system during cooling operation when
the outdoor temperature is +40 °C. F1245 then at-
tempts to get as close to the set temperature as pos-
sible.
use system 2 in cool mode - use system 4 in cool
mode
Caution
This setting option only appears if "passive/act-
ive cooling 2-pipe" or "passive cooling 2-pipe"
is activated in menu 5.2.4.
Here you select whether you want to use climate sys-
tem 2 - 4 in cooling mode (if there is more than one).
If this function is activated, you can set "cooling flow
temp. at +20°C" and "cooling flow temp. at +40°C" for
each climate system where the function is activated.
use room sensor
Here you can set whether room temperature sensors
are to be used in cooling mode.
