thermal insulation in your buil-

ting operation is necessary (e. g., at
night) to prevent considerable cooling.
During reduced operation, the heating
equipment remains in operation with
reduced temperature for any outdoor
temperature and the pump runs.
Normal Operation: The feed tempera-
ture is regulated continuously accor-
ding to the heating curve. The time
control is without function.

8.3 Adjusting the Heating Curve
The heating curve determines what feed
temperature will be set by the heating equip-
ment for a particular measured outdoor tem-
perature. By means of a correctly adjusted
heating curve, a constant room temperature
is maintained for any outdoor temperature.
The heating curve (Fig.
results from a base point (c) and the maxi-
mum feed temperature (e).
8.3.1 Base Point
Adjustment (c)
The base point of the heating curve is the
feed temperature in °C at + 20 °C outdoor
temperature. Values between 10 and 60 (°C)
can be set.
The heating curve shown in Fig.

Temperature (e)
On the feed temperature selector of the hea-

The maximum feed temperature setting of

temperature of –15 °C.
