When this value is reduced correctly then
room temperature increase will be stopped.

8.16
Using parameter
paralel curve movement
set
required room temperature according to
formula:
Required room temperature = 20°C +
heating curve paralel movement.
Example.
To reach room temperature 25°C value of
heating curve movement must be set for
5°C. To reach room temperature 18°C value
of heating curve paralel movement must be
set for -2°C.
In this configuration a thermostat can be
connected. It will level inaccuracy of heating
curve adjustement in case when its value will
be too big. In such case value of decrease of
preset mixer room temperature from
thermostat should be set i.e. for 2°C
.
After
discontecting thermostat plugs preset mixer
cycle temperature will be reduced. By correct
adjustement of this reduction will stop
temperature increase of temperature in
heated room.

Controller ecoSTER200 automatically moves
the heating curve depending on preset room
temperature.
The
controller
relates
adjustements to 20 degrees C, i.e. for preset
room temperature = 22 degrees C the
controller will move heating curve by 2
degrees C, for preset room temperature = 18
degrees C the controller will move heating
curve by -2 degrees C. In some cases
described in point 8.16 it can be necessary to
adjust heating curve movement.
In this configuration room thermostat
ecoSTER is able to:
reduce temperature of heating cycle by a
constant value, when preset temperature in
a room will be reached. Similarly like it was
described
in
previous
point
(not
recommended), or
automatically, constantly correct heating
cycle temperature.
It is not recommended to use both these
possibilities at the same time.
Automatic correction of room temperaturę is
done according to formula:
Correction = (preset room temperature –
measured room temperature) x room
temperature factor / 10
Example.
Preset temperature in heating room (set in
ecoSTER200) = 22 degrees C. Measured
temperature in room (using ecoSTER200) =
20 degrees C.
room temperature factor
= 15
Preset mixer temperature will be increased
by (22 degrees C – 20 degrees C) x 15/10 =
3 degrees C. Correct value of parameter
must be found room temperature factor.
Scope: 0…50. The bigger value of factor the
bigger
correction
of
preset
boiler
temperature factor. When set on value “0”
preset mixer temperature is not corrected.
Attention: setting too high value of room
temperature factor may cause cyclic room
temperature fluctuations.

WEATHER CONTROL
Depending
on
measured
outside
temperature, automatically controlled can be
either preset boiler temperature and mixer
cycles temperatures. By correct adjustment
of heating curve temperature of heating
circuits is counted automatically depending
on value of external temperature. Thanks to
that by choosing proper heating curve for
given building, room temperature remains
approximately the same – no matter what
outside temperature.
