Adjusting the heating curve
If the heating circuit is always too warm or too
cold, the
fl ow temperature
must be adjusted. This
can be done using two parameters:
"Flow at -10°C"
and
"Flow at +10°C"
.
No large jumps in temperature
Do not set any large jumps in temperature when
adjusting "Flow at +10°C" and "Flow at -10°C":
For
underfl oor heating, never more than 2°C
For
radiators never more than 4°C
You may need to alter the fl ow temperatures
again after one or two days, but working in small
steps will help you to set the heating circuits more
precisely, thus saving energy.
During the transition period -> "Flow at +10°C"
If the heating circuit is always too warm or too cold
during the
transition period
(spring and autumn),
only
the fl ow temperature for
"Flow at +10°C"
is
reduced or increased
.

Factory settings for the
heating circuit
With
software versions 1.20.0
and higher,
the system confi guration for the heating circuit
offers the user a choice between
underfl oor and
radiator heating
.
This choice pre-sets some of the parameters in the
heating circuit. These parameters and their factory
settings can be seen in the table below:

In winter -> "Flow at -10°C"
If the heating circuit is always too cold or too warm
in winter
,
only
the fl ow temperature
"Flow at -10°" is increased or reduced
.
