Select this position when the thermal in-

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-

ing up late as an exception (e. g., party). In this
case, the setting on the time switch (accesso-
ry) for reduced operation is ignored. Do not
forget to switch back again later to automatic
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 heating curve (Fig.
sults from a base point (c) and the maximum
feed temperature (e).
When commissioning, set flow temperature
control so that the dot is pointing to the right

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 permits,
Tip
select a lower setting value (e. g. 20). In case
the room temperature is too low with fully
opened thermostat valves, select a higher
value. (e. g. 30).

cia (e), the maximum heating flow tempera-
ture can be set between approx. 40 °C and
approx. 90 °C.
The maximum flow temperature selected here
is only reached with an outside temperature of
–15 °C (Fig. , Point e).

Note: The feed temperature selector (e) is
also the switch for summer operation
( , left end position).
Therefore, note the setting for the
average feed temperature (Fig.
Point e) for winter operation.
The required radiator temperature (flow tem-
perature) for an outdoor temperature of
–15 °C is contained in the design data of the
heating system. If this information is not avail-
able, values gained by experience must be
used.
