Attention: Care should be taken during the
frost protection function that the
feed temperature selector on the
heating unit is set to at least "1".

Automatic switching between normal and re-
duced operation according to the time switch
program.
Select this position when the thermal in-
Tip
sulation in your building is not so good and re-
duced heating operation is necessary (e. g., at
night) to prevent considerable cooling. During
reduced operation, the appliance remains in
operation with reduced temperature for any
outdoor temperature and the pump runs.
7.2.3 Continuous Normal
Operation
The flow temperature is not reduced.
Select this setting when you will be stay-
Tip
ing up late as an exception (e. g., party). In
this case, the setting on the time switch (ac-
cessory) for reduced operation is ignored. Do
not forget to switch back again later to auto-
matic switching operation
7.3
Setting the Heating Curve
The heating curve determines the flow tem-
perature to which the appliance is limited,
based on the measured outside temperature.
With a correctly set heating curve, a constant
room temperature is maintained for any out-
door temperature.

The base point of the heating curve sets the
flow temperature (radiator temperature) in °C
when the outside temperature is +20 °C. It
can be set to values between 10 and 60 (°C).
The heating curve shown in Fig.
base point of 25 °C. This setting of the base
point should be selected as a first starting
point.
In case your heating equipment per-
Tip
mits, select a lower setting value (e. g. 20). In
case the room temperature is too low with ful-
ly opened thermostat valves, select a higher
value. (e. g. 30).

between
45 and 87 °C.
The maximum flow temperature selected here
is only reached with an outside temperature of
–15 °C (Fig.
